Diesel engine BMW 2.0. Four most reliable BMW engines. BMW N20 engine modifications

(Cars BMW 125i BMW 220i, BMW 228i, BMW 320i, BMW 328i, BMW 420i, BMW 428i, BMW 520i, BMW 528i, BMW X1 2.0, BMW X1 2.8, BMW X3 2.0, BMW X3 2.8, BMW X4 2.0, BMW X4 2.8, BMW Z4 1.8, BMW Z4 2.0 release after 2011)

The N20 engine is a four-cylinder BMW engine with a turbocharged and direct gasoline injection into a cylinder, which is installed on various BMW models with indexes 1.8i, 2.0i and 2.8i at the end of the name after 2011.

Before we proceed to the conversation about the BMW N20 tuning, I propose to get acquainted with its design and modifications.

The BMW N20 engine was first introduced in 2011 along with the BMW X1 2.8 xDrive car. In the future, this engine appeared on the following models: BMW 125i; BMW 220i, BMW 228i; BMW 320i, BMW 328i; BMW 520i, BMW 528i; BMW X1 2.0 xDrive, BMW X1 2.8i xDrive; BMW X3 2.0 xDrive, BMW X3 2.8 xDrive; BMW X4 2.0 XDrive, BMW X4 2.8 xDrive; BMW Z4 1.8i, BMW Z4 2.0i and BMW Z4 2.8i.

During the release of various models of BMW N20 engines, the following engine control units were used (ECU): MEVD 172.2, MEVD 1724, MEVD 1729, MEVD 172P.

Initially, an engine with a capacity of 245 hp was presented. At 5000 - 6,500 rpm, and the torque of which reached 350 nm. at 1250-4800 rpm.

Motor modifications BMW N20.

Power and torque diagrams of various BMW N20 engines.

Consider the features of the design of this motor.

Fully aluminum block of cylinders with wear-resistant coating of the walls of cylinders. This coating is formed as a result of gas-gauge spraying of the molten steel wire, which results in an electrocardial metallization (EDM) with iron aluminum. This technology allows on the one hand to ensure the advantages of fully aluminum blocks of cylinders (alusyl), providing a minimum gap between the piston and cylinders, and on the other hand provides high strength of the cylinder wall.

The cranked shaft with the diameter of the connecting rod and the root neck of 50 mm, turned out to be sufficiently easy for the motor with such power (13 kg against 21 kg on the BMW N52 motor).

A new engine control system of Bosch MEVD 172X, based on Infineon Tricore processors, which provides greater speed of work compared to predecessors. The program store is now located in the processor itself and there is no loss when transferring information between different elements of the control unit.

System of lubricant with performance adjustment with an electromagnetic regulator, which will ensure the necessary oil pressure in any conditions.

Combining into a unified management system of all modern gas distribution systems and mixing: the system of adjusting the position of the camshaft Double Vanos.; System of stepless adjustment of inlet valves Valvetronic; System of direct gasoline injection into a cylinder and turbocharger with turbine Twinscroll.

All these systems are combined into a common name. TVDI (TURBO-VALVETRONIC-DIRECT-INJECTION) and provide the widest possibilities for adjusting the phases of gas distribution and the formation of local combustion zones of the mixture in the cylinder with the required degree of enrichment.

Valvetronic. Consists of a system of stepless adjustment of the stroke of valves and the phase adjustment mechanism of gas distribution Vanos. With which it is possible to flexible control of the course and phases of intake valves, as well as adjustment of the phases of the exhaust valves.

The mechanism is based on the eccentric shaft of a worm electric drive and a complex system of pushing levers. This is already 3 generation of this system, which despite the complexity of the design as a whole has already proven its reliability.

Also, adjusting the stroke of the ink valves ensures the function of throttling and allows you to control the engine power instead of throttle, which ensures high reaction rate to the position of the gas pedal.

As well as on the BMW N55 motor, the film Valvetronic is located inside the head of the cylinder head and no longer acts as an alien tide on the valve lid.

Turbochards. - The BMW N20 motor uses a turbocharger with one turbine made by technology. Twinscrollwhich allows you to isolate the exhaust gases by group of cylinders 1-4 and 2-3.

This significantly increases the efficiency of the turbine and allows you to simultaneously use the turbine to drive not only the pressure and temperature of the exhaust gases, it and the energy of the pulse superior wave. Thus, due to the special design of the exhaust manifold and the turbocharger, the minimum time of the engine reaction is achieved on small revolutions.

Adjusting the performance of the turbocharger occurs due to the opening of the bypass damper and redirecting the part of the exhaust gases bypassing the turbine. This flap is controlled by a vaccinal drive and a piezoelectric valve.

As in previous motors, the turbocharger and the exhaust manifold forms a single part, which provides minimal distances between the exhaust valve and the turbine, as well as the overall compactness of the design.

In general, thanks to all these newest technologies and systems, a rather interesting motor was turned out, which is 113 kg with weight. (against 178 kg at BMW N52) provides a significantly better characteristic of a torque and economy.

Technical characteristics of the BMW N20 motor:

Tuning motor BMW N20.

How easy it is to understand from the previous description, in fact, only two BMW N20 motors: one with a compression ratio of 10: 1, and the other with a compression ratio 11: 1. Otherwise, the richness of the model range is provided by the various settings of the engine control unit.

Constructively differed of these motors only in the form of pistons. For motors with a compression ratio of 11: 1, a piston with a smaller amount of deepening in the bottom of the piston is used.

Thus, any motor with a compression ratio of 10: 1 can be pushed to the power level of 245 hp. This applies to the BMW Z4-1.8i, BMW 125i, BMW-X1 20I and BMW-X3 20I models, as well as some models with an index 20i, on which there is a low compression engine (supplied to poor gasoline countries, the S858 option).

For the remaining models with the N20B20-U0 motor to achieve the parameters, the identical factory must be changed by the piston. However, the practice has shown that the motors with the degree of compression 11 as a whole work perfectly on the regular firmware of 245 drugs.

Considering the foregoing, we can concure the conclusion that the most effective way to forcing the BMW N20 motor is.

Of course, there is reason to believe that in adverse conditions (hot weather, high load and impaired engine thermal mode) The detonation control system will reduce the engine power on some value, but still it will be greater than regular 184 drugs.

Let's look at what is the degree of compression and the danger of its high values.

The degree of compression is the geometric indicator of the engine, which is determined by the ratio of the total volume of the cylinder to the general combustion chamber. The higher the degree of compression, the higher the pressure in the cylinder before the ignition of the fuel mixture, and, accordingly, the higher the temperature and pressure of the working fluid at the beginning of the tact work. As well as higher engine power and its better economy.

However, it is possible to raise the degree of compression to a certain limit, overcoming which you can destroy the engine.

What is having a higher degree of compression. The answer, in general, is obvious - detonation. When the compression pressure is exceeded above, the local burning zones of the fuel mixture with supersonic velocity - explosions inside the cylinder, which lead to the occurrence of shock waves that destroy the engine.

Usually for a modern motor operating on gasoline 91-98, the compression ratio is in the range of 10.2-11.3. For turbocharged motors, the compression ratio is reduced to 8.5-9.5. This is due to the fact that for the occurrence of detonation, the absolute pressure in the cylinder before ignition is critical, and not the nominal value of the compression ratio. For obvious reasons, motor turbocharged pressure in the cylinder is greater than atmospheric with the same degree of compression.

However, BMW motors with direct fuel injection into the cylinder and Valvetronic have become an exception to this rule. For example, the BMW S55 motor, having a sufficiently high degree of superior (liter power of 143 HP), has a compression ratio of 10.2: 1.

This is primarily due to the features of the working process of motors. TVDI: Due to the formation within the cylinder of local zones with a normal or slightly enriched mixture and evaporation of injected fuel, ideal conditions for combustion of the fuel mixture are created. Thus, it became possible for the reliable operation of such engines with turbocharged with a compression ratio of 10-11 without detonation.

The design of the BMW N20 motor, as a whole, identical to the S55 motor from BMW M3 F80 and taking into account liter power in 122 hp. and technology TVDI, Compression at 11: 1 does not look so much high.

It should be understood that after an increase in power up to 245 hp. Some restrictions will appear during the operation of such a motor:

1. It is necessary to use only gasoline AI 98. The use for this gasoline motor 91 is categorically contraindicated, and 95 is undesirable.
2. Requirements for the cooling system are increasing - picky health control: regular flushing of the radiator and checking the thermal mode of operation of the engine.
3. Requirements for lubrication system increase: unambiguously apply a short oil change interval and control over the state of engine parts for the formation of deposits on them, which may worsen the heat removal from the GBC parts.

Otherwise, your BMW with an index 2.0i end of the model name can easily get under the hood of 245 hp.

If you want to get the power of more than 245 drugs, then the piston is still better replaced.

When tuning a BMW N20 motor with a low compression ratio without a special risk for reliability to obtain a power of 290 drugs and a torque of 420 nm.

Tuning and warranty

Perhaps the most exciting question: Is it possible to increase the power and save the warranty?

Apparently an unequivocal answer to this question can only be given by specialists from the BMW-AG itself. We can only provide for a number of events that it would be impossible to detect traces of chip tuning by means of standard diagnostics (maintaining original firmware identification numbers and programming records)

Unfortunately at the moment there is no possibility to work through the OBD2 connector. The engine control unit must be dismantled, then by activating the boot mode, you can download or pour the program.

You can pour either a standard program or modified.

In the case when you need to debug a program or for one reason or another, it is necessary to regularly change it, it is possible to install a special board into the computer that can turn on the boot mode without dismantling the ECU from the intake manifold. What will significantly simplify the work on chiptuning.

Earlier I was interested in buying cars "without looking." This time the approach was founder. I visited a test drive at a direct competitor, visited a couple of alternative car dealerships.

Challengers were Lexus GS, Mercedes E-Class, Audi A6 V6 Quattro. In BMW, the test was given a diesel three-liter BMW 5-Series with a full drive. A little was familiar with such a motor, rode shortly before it on x5 and x6. I liked him before, but the price was upset.

It is a pity that there was no shares on such a complete, as on Audi A6. The test machine with the engine did not turn out more. But in the presence of several BMW 5 to choose from, different configuration, colors and discounts!

My not solvent appearance helped. I have already decided to buy at the price of price in a couple of days. The manager thought that I had doubts and began to call every day with a special offer for me. As a result, the final discount turned out about 300,000 rubles! Pleasantly!

Approach to the client in BMW at a good level, when issuing a bottle of wine or champagne gave a bottle. As a result, I bought the BMW 520i. Motor 2.0 liter, two turbines, 184 horsepower. Automatic transmission on 8 gears. Color "Brazilian cherry". Salon black. Artificial material that is more durable of genuine leather. Runflat tires with full color. Oil dipstick is missing.

Impression

At the go, I liked the car from the first meters. This is the case when the characters coincide. By smoothness, the machine turned out to be more comfortable than BMW, on which I had to ride before. Whipped, chain, at high speeds stable.

The optimal motor for ride is slightly above average. Allows you to go confidently, allowing sharp overtaking on the tracks in the usual speed ranges. Start from the place is not a formula, but for me sufficient.

The sound of the engine during disperses is not a four-cylinder, much more solid, and at idle - normal. The maximum speed machine performs, experimented a couple of times. Consumption corresponds to the passport characteristics, experimented in various modes.

The minimum 4.7 liters per 100 km machine utilizes, provided that smooth movement in a straight line at a speed of about 65 km / h. The tracks went out 5.8-6 l at speeds of about 110 km / h. In cities, the variation is large from 8 to 14 liters, depending on traffic jams.

ACP is really the best! Transfer switches wonderful! Engineering masterpiece. In Eco mode, the movement in the rolling, the engine turnover is dropped to idle, with no braking with a motor. On the descent of rolling speed grows. That is, the effect is the same, as on the mechanics, turn on the zero point. The manager in the cabin said that there is a certain opening mechanism in the box, the clutch semblance. It breaks the connection of the motor with wheels when moving rolling.

Sport mode holds the transmission below the usual so that the engine turnover is kept in the maximum motion return range. It allows you to ride more intense, but in general the car becomes sharp, nervous. Quickly, but not comfortable. Bored. And listen to the sound of the motor on top of music do not want.

Salon in the BMW 5-series F10 looks very good. For me personally, there are several disadvantages that are believed exclusively to this configuration. No, or not enough, lumbar stop, do not like the not folding rear back.

I am a skier, and I do not like to carry the skis on the roof. Closed boxes are too massive, and ordinary mounting on the transverse arcs do not protect against dirt on the roads, besides, they are noisy at speed. There was no exit, bought original crossbars in the foot holes on the roof and to them ski fasteners.

They are stamp BMW, but very much like Thule products, which is not bad in principle. Convenient design, thoughtful. But immediately after washing on the road, it is impossible, the locks of the fasteners freeze completely. It is necessary to dry carefully, a simple purge compressor is not enough.

The climate in the car is excellent, noises from the minimum airflows. Music on the Four. In car audio, I understand a little, I can distinguish the quality. Here is not a masterpiece, but tolerable. In any case, I have not met better sound in basic equipment.

Who needs a better sound, you can take the extra charge of Harman / Kardon or Bang & Olufsen. The latter is more expensive than the average car in Russia. Cruise control is convenient, with digital indication. There is an interesting LIM button, limiting speed.

Start-stop system did not like! I do not leave the feeling that for the sake of fuel economy, I voluntarily utilize the battery and starter. I did not consider it, but I am sure that the saved gasoline at cost does not compare with their purchase.

The start-stop system at each start of the motor is activated, I disconnected it with the button each time. It is said that she has a firmware that remembers the previous mode and saves it with the next engine start. But I did not reach it.

Runflat tires. We already exploit on them already the second car, no inconvenience. Bought a car on summer RF. In winter, I bought a set of ordinary wheels and a branded kit (spare track + jack + key). The difference in hardness with ordinary is felt only on the day of shifting.

Then these sensations are blurred in daily operation and do not remember at all about what rubber you are going. The spare wheel lies in the trunk of 6 months and takes a third of the space. A couple of times in traveling it prevented, it was not useful to directly appropriate.

On Summer RF, there was a serious puncture, caught a nail 150 km / h. Reacted the pressure sensor. Visually the wheel looked usually, went further. On the way drove onto the tireage, the pressure gauge showed 0.5 or 0.8, externally nothing special. Removed the wheel, made, put back in 5 minutes.

In the trunk lies a compressor for a bicycle, which needs a constant swap. The device itself is compact, lies in a niche. Power is more than enough, I hope for the car it is not useful.

Availability of problems

There was one serious breakdown. Its difficulty is not technical plan, but rather in the circumstances under which everything happened. On the day the car did not show signs of life. No way! I called a taxi and went on business, on the way I called the Central Agency BMW by number with a Moscow code. Answered the girl. I explained to her the situation. She asked VIN and said that he would call back. And the main problem was that the nearest dealer in another region. Go to it about 500 km. The girl called back instantly, said to wait for the tow truck. In the evening of the same day, the crane arrived from Irkutsk, gently loaded and left. The next day they called from the service in Irkutsk. They said that they found a malfunction and eliminated it. Asked my opinion on how best to return the car. After a couple of days I took it myself. Clarified the cause of the fault. It turned out, the satellite security system Cesar Satellite was shot. By the way, the evacuator of the stranger, the service does not have any relationship. I paid his work myself, although I did not invite him. I gave him about 45,000 rubles, later the dealer sent me exactly this amount to the account. Next breakdown - Parktronic. She showed that I was all the sensors around the obstacle, both in front and rear. Chose the time to service. Understood quickly. Wrought off the wiring from one sensor in the bumper, for this reason the whole system could not work. Asked how this is possible in the new car. They said that there was a blow to exactly the angle of the bumper, where the sensor is located, or the sensor itself, so the connection was damaged. I was very surprised by this arrogance, because I know that I did not beat the car. I was invited to the repair area, put a bright lamp and finger showed barely notable traces on the paint, which are practically not noticeable. And indeed, the very corner. The diameter is such as if this angle was tortured, and then he himself returned to the previous position. I assume that the neighbors in the parking lot tried. The sensor was changed for free, did not take anything for work, although this is not a warranty case. Trifle, but it's nice that there is such a service. There was still a replacement of a pair of stabilizer stabilizer rates when running 50,000 km. Cars exploit active, runs are usually large. On this car drove a little more than 50,000 km per year. Sold after 1 year and 3 months of operation when running about 57,000 km. I do not suffer greed, so I sold the car in a couple of days.

Outcome

The car is good in everything, or almost everything. The most important thing is that he is trouble-free. That is why I bought the next almost the same. If someone considers the purchase of the BMW 5-Series F10, then do it boldly. Regrets later, I think it will not. Good luck to all)

This review presents BMW gasoline and diesel engines used in the past 15 years. Because of the huge range of power units of the Bavarian company, we cannot cover all engines and their options. However, let us dwell on the most famous and popular engines.

BMW is one of the world's leading manufacturers offering the most advanced and advanced power units in the market. Therefore, it is necessary to be ready for big care for maintenance and repair. For examples, it is not necessary to go far - for many owners, it becomes a surprise. The need to periodically replace the TRG chain drive used in all modern BMW engines. Chain and tensioner, as a rule, are taught about 200-300 thousand km. At the same time there is noise, and the engine works unevenly. To replace the timing chain, it is necessary to prepare about 20-30 thousand rubles. In the case of old copies, difficulties occur when trying to carry out overhaul - materials used for the manufacture of cylinder sleeves do not allow them to recover.

What expenses await you after buying a used BMW depends on the state of the car and the engine version under the hood. Our review will definitely help make the right choice.

Gasoline engines

1.8 I N42, 2.0 I N46

Short description:

Atmospheric

4-cylinder

16-valve

Multiple fuel injection (distributed)

The N42 and N46 engines from 2001 to 2007 are one of the most popular four-cylinder BMW units on the secondary market, mainly due to the "Three" E46 and the Compact version based on it. These motors can be found in "units" E87 and Troika E90 of the initial production period. It seems that BMW with a 4-cylinder engine is not a real BMW. But it is necessary to honestly admit that these small engines are unique technical masterpieces. Both are equipped with a timing chain drive, both have a Double Vanos system - a system for adjusting the phases of gas distribution and exhaust valves, as well as the Valvetronic system - the original solution for smooth changes in the height of the inlet valves, replacing the familiar operation of the throttle.

The main advantage of the presence of the ValveTronic system is a significantly lower fuel consumption (on average by 1.5 l / 100 km), compared with conventional engines.

What is interesting, the Motors N42 and N46 perfectly perceive the transition to work on liquefied gas. The main thing is the right choice and professional LPG installation.

Well-groomed 4-cylinder engines do not require large operating costs. Visible an instance with a real mileage of less than 200,000 km, you will be satisfied with your choice.

Malfunctions due toLPG.

Despite the fact that the motors without consequences perceive the transition to work on liquefied gas, a non-professional approach to the choice and installation leads to sad consequences. Valvetronic does not tolerate amateur, the result of which damage to the head of the cylinder block and burned valve seat. Before purchasing a car with LPG, you need to visit the car service and check the motor status.

Multiple fuel injection (immediate)

Models of compact and middle class

In 2006 and 2007, a new era began for BMW lovers. It was then that the German manufacturer updated the line of the engines by entering completely new motors into it. Some of them are two modified engines: 1,6-liter power 122 hp - N43 B16 and a 2-liter capacity of 143 and 170 hp (N43 B20). Both engines received a direct fuel injection. This means a decrease in fuel consumption with the preservation of high characteristics. But on the other hand, it means a higher cost of possible repair and complexity of the LPG installation.

Operation and typical faults

The N43 series engines are considered among the most reliable among modern BMW motors. They are ideal for those who look after the BMW E90 and, as a rule, does not wind up a lot of kilometers per year. But still problems are found.

Valve train chain

There are cases of premature wear of the timing chain chain. The problem concerns, above all, cars collected until 2009.

Uneven work

Failure in the operation of the ignition system due to the failure of coils. Symptoms are accompanied by an engine malfunction signaling device.

Failure of the fuel pump

This malfunction more often worries 6-cylinder engines, which will be written below. But sometimes the fuel pump failure has to be encountered in earlier copies of 4-cylinder engines. Alarm symptoms - problems with the launch and lack of thrust in the upper range of revolutions.

Specifications 1.6 I N 43 B 16, 2.0 I N 43 B 20

Application

The N43 series engines were used in all small and medium-sized BMW models. The 1.6-liter motor was used as in Mini and Peugeot.

If someone plans to install gas equipment on this motor, then it is better to pay attention to older N42 and N46 engines. In other cases, this is a very good choice.

Alternative

The direct alternative to this motor can be a 4-cylinder diesel N47.

2.0i - 2.8i M52

Short description:

Atmospheric

6-cylinder

24-valve

Models of medium, top class and sports

M52 family engines debuted in 1994 on BMW 3 series E36 cars. M52 - Further development of reliable and powerful M50. The main difference is the use of an aluminum block, which made it possible to reduce the weight of almost 20 kg. Together with light rods, a chain tensioner and a graduate collector, a new engine has become easier than the predecessor almost 30 kg.

The M52 engines family are represented by motor vehicles 2.0, 2.5 and 2.8 liters, developing 150, 170 and 193 hp. respectively. S52 with a capacity of 243 hp A volume of 3.2 liters, installed on M3 and intended for the North America market, is closely related to M52.

In 1998, the BMW 3 E46 series appeared an updated M52TU engine appeared. It is distinguished by the use of a system for changing the phases of gas distribution inlet and exhaust valves (Double Vanos system). In the first engines, the change in the phases of gas distribution was carried out only on the intake shaft. The engine power has not changed, but the characteristics on low and medium turns have improved.

Operation and typical faults

M52 family engines are a classic genre. He enjoys a good reputation, belonging to lasting and reliable, but does not tolerate tough exploitation and negligent service.

Trucking gasket GBC and cracks in GBC

Row six-cylinder engines are sensitive to overheating: a long head can burst. At best, triggers the gasket of the GBC. The troubles are facilitated by frequent problems with the cooling system and the radiators fan drive. Ignoring the symptoms of overheating can lead to a planning result, when the most efficient and economically advantageous way of repair will be the acquisition of another motor in working condition.

Distributional position sensor fault

The defect is manifested by uneven engine operation and sluggish engine spinning after warming up. The refusal can also be accompanied by a difficult launch - for a long time to turn the starter. Cheap analogues will cost less than 1,500 rubles, Siemens products are more expensive - about 3000 rubles. The replacement will not be difficult even for a non-specialized mechanic.

High oil consumption

In old age, the degree of wear of most engine elements is increasing. A considerable contribution to the oil consumption brings the oil-giving caps producing their resource.

Ignition coils

One coil for M52 engine costs about 2000 rubles.

Application

M52 family engines were installed both in small cars of the series 3 and Z3 and in the flagship BMW 7 series.

BMW 3 series E36: \u200b\u200b04.1994-08.2000

BMW 7 series E38: 08.1995-11.2001

BMW 5 E39 series: 11.1995-09.2000

BMW Z3: 04.1997-01.2003

BMW 3 series E46: 02.1998-05.2002

Rating: ☆☆☆☆

In principle, each of the M52 engines is worthy of recommendations. The 2,8-liter version of the engine is in the greatest demand. It is considered the most reliable and guarantees satisfaction from operation. However, find a well-kept copy every day is becoming more difficult.

Alternative

In the case of high-generation models, in particular BMW 3 E36 series, you can choose M50.

2.2, 2.5 and 3.0M54.

Short description:

Atmospheric

6-cylinder

24-valve

Distributed fuel injection

The M54 series gasoline engines are one of the best BMW row six. They fell under the hood of many Bavarian models.

R6 M54 debuted in 2000 in three versions: 2.2, 2.5 and 3.0. All options received a system for changing the phases of the gas distribution of intake and exhaust valves (Double Vanos).

The owners praise not only a pleasant sound and good engine performance (especially 2.5 and 3.0), but also reliability. However, you should not count on fuel efficiency.

M54 engine disappeared from the list of proposals in 2007 along with the BMW E46 convertible.

Operation and typical faults

Serious malfunctions are rare and most often arise due to very large runs, negligent maintenance and non-professional repair.

The only problem is an overly high oil consumption. Losses arise as a result of oil fracture and due to the specific design of the oil separator, which leads to clogging of the ventilation valve of crankcase gases. As a result, excessive pressure in the engine is increasing, which contributes to even higher loss of oil.

Application

The N52 engines family debuted in 2004 with a 3-liter engine in the BMW 630i E63 car. In 2005, his modification with a working volume of 2.5 liters appeared. For weight saving, the engine block is made of aluminum and magnesium alloy. There is also a system of smooth change of valve stroke Valvetronic and a voltage distribution system of Double Vanos. The engine that came to shift in 2011 is a direct heir to N52, but already with turbocharging and 4-cylinders - a typical example of downsaysing.

Operation and typical faults

Noise of hydrocompensators

The problem concerns primarily engines made at the initial stage of production - until November 2008. Subsequent engines obtained the recycled head of the cylinder block.

Cooling system failure

There are malfunctions in the electric pump of the cooling system, resulting in serious consequences. Replacing costs about 15,000 rubles.

COMMON RAIL Injection System

The power unit with codenamed M47 is a 2-liter diesel engine used from 1998 to 2007. Interestingly, under the code M47, two generations of 2-liter diesel engines are hidden: the first generation - until 2003, a working capacity of 1951 cm3, and since 2001, a new generation of 1995 cm3 working volume. The first M47 was with an TNVD, and the second with the Bosch Common Rail injection system.

The 2-liter M47 can be found as in the models with the mark "18", for example, BMW 318D, and marked "20", for example, BMW 320D. With the same working volume, they differ in equipment and developed power. M47 1951 cm3 was also used by the English Rover in the Land Rover Freelander, MG ZT and ROVER 75.

Along with increasing capacity, the engine received balancing shafts. Turbocharger instead of vacuum control purchased more accurate electric. A good torque curve was obtained thanks to the use of a variable inlet geometry of the intake manifold: the dampers adjust the air flow depending on the rotor of the engine. Each version of M47 has a timing chain drive, and in this series of engines, unlike the N47 receiver, it is placed in an easily accessible place - in front of the engine. All M47 have a two-mask flywheel, and the last instances can be equipped with a DPF filter.

Operation and typical faults

M47 engine advanced in technical plan and sometimes causes difficulties from mechanics with proper conclusions in diagnosis. However, compared to the successor N47, it should be considered as a less problematic and more successful motor. Versions with power from 143 hp Provide excellent performance, and at the same time quite economical. For example, a 163-strong 320D consumes an average of about 6.6 l / 100 km.

Destruction of intake manifold dampers

This is a typical malfunction of many BMW diesel engines, including six cylinders. The dampers responsible for changing the geometry of the intake manifold can break and fly from the axes, hitting directly into the engine. This leads to damage to the head of the cylinder block (the destruction of combustion chambers), turbocharger, and sometimes pistons.

Premature failure of the turbocharger

Lowly the resource of the turbocharger often accuses the increased period of oil replacement. To prolong his life, it is better to reduce the prescribed intersavice oil replacement intervals. Since the turbocharger has electrical control, not all workshops involved in the restoration of turbines can adjust it after repair. However, it is technically possible.

Wear shkiva

The source of suspicious knobs from the engine often becomes the separated damper pulley, which is responsible for the drive of attachments. However, sometimes, similar noise makes a two-mask flywheel, located on the other side of the engine.

Application

In view of a large power range, the M47 series engine was installed in a compact BMW 1 series, a crossover X3 and even in the BMW 5 series.

Among similar turbo diesel engines of their years, M47 succeeded in technical terms and in terms of performance. This is a very good engine, although it is not worth counting on a cheap service. It has a number of technical solutions that require high maintenance costs. However, the engine cannot be described as very problematic.

Alternative

Among the diesel engines BMW, in principle, there is no large selection, except the 2-liter M47. The remaining engines are much more powerful.

COMMON RAIL Injection System

Models of compact, middle class and SUV

In March 2007, BMW released a new generation of two-liter diesel engines N47. The engine design has changed fundamentally: the cylinder block is made of aluminum alloy, which made it possible to save 17 kg, the timing of timber moved from the front of the motor to the back - to the flywheel. Most of the engines of this series came across the energy recovery system during braking, the so-called Efficient Dynamics.

All engines of the N47 series with a capacity of 163 hp Piezoelectric injection system COMMON RAIL with a working pressure of 1800 - 2000 bar. Weaker engines are equipped with electromagnetic nozzles with a working pressure of 1600 bar. Since the new engine has a greater torque than M47, the crankshaft had to be strengthened. Very interesting versions with a capacity of 204-218 hp, which have a consistent predatory with two turbocharger of various sizes. This is the strongest 2-liter turbodiesel in the world. In 2013, the N47 of the working volume of 1598 cm3 appeared with a reduced step and diameter of the cylinders and another block design. He received the designation 14D, and its power is 95 hp

Operation and typical faults

Diesel N47, taking into account productivity, is a very economical engine. High estimates deserve performance, minimal vibration and pleasant sound. A powerful torque, available already from low revolutions, indicates that even large and heavy cars, such as 520D and X3, will not experience any problems with the dynamics. BMW 520D F10 Weight more than 1600 kg is satisfied on average just over 7 l / 100 km, which is a very good result. N47 in terms of fuel consumption is more economical than its predecessor M47.

Imperfection TRM

Located in uncomfortable place, the timing chain drive turned out to be extremely unreliable. In poor-quality lower stars, the teeth were rapidly wear out, which led to damage to the chain. Noise from worn items could appear after 60,000 km. In extreme cases, it came to the jump of the chain or its rupture. Theoretically, the manufacturer solved the question in 2010, but opinions about the achievement of a positive result of contradictory. There are cases when after warranty replacement of the timing chain, the alarming noise appeared again - approximately, after 150,000 km.

Badgent damper

The problem is similar to the one that exists in M47: the flaps are cleared, fly and fall into the engine, damaging it and turbocharger.

Piezoelectric nozzles

They are used in high power engines. The nozzles of this type are not subject to recovery, so if their owner malfunction is expected to be high. Under normal operating conditions, nozzles confidently go more than 200,000 km.

Application

Since March 2007, the engine gradually replaced its predecessor. In the new version of the "Five" 2-liter biturbo replaced the 6-cylinder diesel 525d.

Models of the middle class and above, and SUV

M57 engines family with the Injection System Common Rail debuted in 1998, i.e. Less than a year after the first diesel engine was presented with the CR system for the Serial car Alfa Romeo 156. Diesel BMW received many Awards "Engine of the Year" in its category. This power unit was used by other manufacturers: the 2.5-liter version of M57D25 hit Opel Omega, and a more powerful version in Range Rover.

Diesel with the designation M57 has a cast iron block, 6 cylinders located in a row and aluminum head with two upper camshafts. Power supply high pressure pump, fuel ramp and nozzles - depending on the year of the production of electromagnetic or piezoelectric.

In the process of production, its design changed several times: in later models indicated by M57N and M57N2, the timing chain is activated only one camshaft, and on another camshaft is transmitted through a toothed gearbox. Similarly introduced modifications with electrical control of turbine blades, a new generation Common Rail injection system with a higher operating pressure and solid particle filter. The top version of the M57TU2D30 has two turbocharger and power 286 hp

Operation and typical faults

The first versions of the M57 engine are considered not killed. There are cases when the BMW 5 series with this engine drove 1,000,000 km without overhaul.

Inlet collector flaps

More powerful versions of the M57 engine are equipped with a system of change in the length of the intake manifold. The weakening of the fastening of the dampers and their "splint" is the most common aless M57. An experimental mechanic will determine the presence of a defect on a rumor. Many are resorted to removing dampers, but it is not recommended to do. The prevailing opinion of the majority is that after removing the dampers, the engine works as well - not exactly exactly. The engine is worse reacting to gas in the lower range of revolutions. The cost of restoring dampers from 5000 rubles and higher.

Damage to pulley M57N.

In the upgraded version of the engine with the index n, relatively quickly fails the pulley of the drive of the attachment, mounted on the crankshaft. This may damage the units, such as air conditioning compressor.

Fuel injectorsCOMMON RAIL.

In earlier versions of the engine, they were durable, but later, from about 2003, the resource was significantly reduced and amounted to just over 100,000 km. In the old versions, the electromagnetic nozzles of the company BOSCH can be restored. In later, especially Buturbo, only replacement. The price of 12,000 rubles per piece is quite reasonable, especially since we are talking about the car dear and prestigious brand.

Inlet reservoir rupture

Met only in the most first parties engines.

Application

The M57 engine is set to a longitudinal front, and the torque is transmitted to the rear wheels or two axes in XDrive versions, where the front wheels get the necessary traction force through the drive shaft.

Each engine has its drawbacks, but M57 is not too significant, and malfunctions can be found and eliminated at the very beginning of their development. The six-cylinder Diesel BMW guarantees a sporting dynamics with a reasonable fuel consumption. The older the engine, the more reliable it. Recommended versions 184 and 218 hp

Alternative

The gasoline 3-liter engine without turbocharging also has excellent dynamic characteristics, is extremely reliable, but consumes 15% more fuel.

Models of the highest class, and SUV

The advanced engine N57 debuted in 2008. The new letter designation is quite justified, since the power unit was fully developed from scratch. Its block is made of aluminum, which is likely to later affect its durability. The Common Rail injection system operates at a pressure of up to 2000 bar. N57 is the first serial engine with a triple superior: this version of the engine, developing 381 hp, received the designation N57S. After such a motor, Buturbo will not surprise none. N57 engines are very often combined with a full drive. A pair of motor is installed only the 8-speed "automatic". All N57 have a diesel filter.

Operation and typical faults

Cutting chains

This problem takes an increasingly acute character, and BMW does not cover the costs in the post-warranty period. Large intervals between oil replacements adversely affect the condition of the tensioner and the chain itself.

Appearance of Nagara

The owners report that the N57 engine is inclined to accumulate in inlet channels. In some cases, already at 70-80 thousand km, the mileage needed a disassembly of the engine for cleaning it.

Application

Aluminum N57 gradually replace the old M57. The engine is not used in other brands.

N57 is not the engine on which you can save. It has excellent performance, but its service is worth a fortune.

Alternative

Similar characteristics provide only 4.4 TURBO V8 engine, indicated by N63.

Conclusion

General Rule concerning BMW engines Simple: All motors such as gasoline and diesel, rather durable and have relatively few weak points. However, if a malfunction appears, it is necessary to prepare for large expenditures on its elimination. You should avoid buying a cheap car, with a dubious past. Such savings will quickly come out. It is also impossible to neglect the regular control of the engine's technical condition.

To the restyling version of the BMW X3 Facelift 2014, a new generation of diesel engines was presented, which in subsequent years can become an integral part of the European BMW Car Park. The B47 engine, as well as its predecessor N47, has four cylinders and 2.0 liters of working volume. Numerous enhancements were aimed at reducing fuel consumption and improving the sound of the motor. In one of the interview with Christian Bok (Christian Bock), heading a new engine development project, disclosed information about many technical features of a new 4-cylinder diesel unit, which is offered in options from 150 and 190 hp

It is impossible to overestimate the significance of the economical, but a powerful diesel engine for the European market. For example, Motor 520D not only longly dominates in the BMW of the 5th series, but also very popular in the 3rd series and models of elevated passability x1 and x3. With the release in 2014, the restyled version of the BMW X3 F25 LCI previously used engine N47 will go to a well-deserved rest and will be replaced by the new BMW B47.

Like its predecessor, B47 has four cylinders located in a row, injection system with a common injection pipeline, 1995 cubic centimeters of a working volume and one turbocharger with a variable turbine geometry.

While N47 in the X18D and X20D variants possessed with a capacity of 143 and 184 hp, the new B47 offers 150 and 190 hp. The maximum torque in the case of a 150-strong version remains at 360 Newton meters at 1500-2250 revolutions per minute (earlier: 1750-2500 rpm). In a more powerful series, this figure increased from 380 to 400 nm at 1750-2250 rpm (previously: 380 nm at 1750-2750 rpm).

The increase in the power and torque of the engine significantly improved the driving characteristics of the BMW X3. So, X3 XDrive20D is able to reach the mark of 100 km / h 8.1 seconds, which is four tenth seconds faster than before. In addition, the optimization touched and indicators in the intermediate sprint.

The new B47 corresponds to the EURO-6 environmental standard and is characterized by reduced fuel consumption in the Euro-cycle. Depending on the type of transmission and production series, the decrease in fuel consumption is 0.1-0.4 liters. However, there is always a four-cylinder diesel engine will demonstrate a moderate appetite in practice, still have to find out. In the case of X3 SDRIVE18D, low-resistance tires provided a car consumption of 4.7 liters per 100 km in the standard cycle and the status of the most economical SUV in its class.

With confidence you can say one thing: the B47 engine will gradually displacing the N47 and will still provide high performance and reduced fuel consumption not only by restyling version x3, but also to many other Bavarian cars. Nevertheless, from the point of view of the BMW company, its main advantage is another. Compared to the N47, in the new B47 used much more unified parts, which allows them to purchase them by large batches, weightingly reducing purchase prices.

An article about the best BMW engines are their technical specifications and important features. At the end of the article - an interesting video about how the BMW motors do in China.

BMW has over the years of leading position in the automotive market. Engines constructed by engineers of the famous representative of the German car industry meet all modern requirements. Back in the middle of the last century, the creators of the brand formulated the concept, which reflected the meaning of their existence as car creators. It sounded as follows: "Car - for drivers."

Brand history

In 1917, a logo was created, which in our time is a sign of high quality. But its meaning is known not to everyone. Since the brand history began with aircraft, the created logo is directly related to aircraft - it depicts an airplane screw against the blue sky.

It must be said that two-wheeled transport, manufactured by the German car giant, still conquer the hearts of extreme or high speeds. The first car came down from the conveyor only in 1929.

Since the birth of a car brand, the BMW has experienced several large failures. But despite this, they were able to rise to Auto-Olympus and take their honorable place there. The engines produced by the concern over the course of several years occupy leading positions in the most authoritative global competitions. What motors of the German manufacturer are rightfully considered the best in the world?

The first of the first

1999 became significant for all representatives of the automotive business and production. It was at that year that a competition was first conducted to identify the best car engine. Among the nominees were the largest companies from around the world. The first place is absolutely deserved by diesel engines, released BMW:

The best among gasoline engines

Another important advantage of the aggregate is the ability to develop high speed in a short period of time.

Among gasoline engines issued by BMW, the following models can be noted:

The use of aluminum alloy greatly facilitates the design of the motor. This engine model is characterized by the complexity of the lubrication process.

Best diesel motor

Cars with a diesel engine have long and firmly entered the hearts and garages of motorists around the world. This is really a universal unit. He is "excellent" copes with "traction" loads and is able to withstand the carriage of large cargo on an ongoing basis. At the same time, it perfectly copes with the "urban" mode of work.

Infinite braking and sharp starts are transferred to a diesel engine without any problems. But for high-speed trails and racing cars, this is not the best option.

Efficiency is also an explicit advantage of a diesel engine - diesel fuel cheaper than gasoline.

This motor is presented in two configurations - 1.6 and 2.0 liters. But it was the two-liter power unit that won the above awards. The engine is installed at most models E and F classes.

Achievements of recent years

Modern society dictates all new and new rules. It affected the requirements for internal combustion engines. The car lunch of the 21st century wants to get a maximum power from the motor with a minimum of financial investments.

An important factor is the environmental friendliness of transport. "Less exhausts are more clean air" - this is what consumers require from car manufacturers. And the BMW concern provided fans of his car the opportunity to "make the world cleaner."

The use of aluminum alloys and polymer composites made it possible to significantly reduce the total weight of the engine. The difference with N55, which is gradually replaced by B58, is about 100 kg. Carbon dioxide emission level is fully consistent with the Euro-6 category. What can not but rejoice wrestlers for ecology.

Conclusion

The combination of BMW letters has long been a sign of high quality and innovative technological in the world of automotive industry. This applies to all products converging from the conveyor of the German brand plants. Like the first models created in the early 19th century, modern turbocharged engines are surprised by their technical characteristics.

Since the creation of the first car model 303 to this day, the concept of "car - for the driver" retains its relevance. It is guided by both designers and brand designers. Stylish design and manufacturability - a combination that gives the right to car BMW to wear a proud title of leader of the world car industry.
