Since 1999, Renault Concern starts the release of K4M engine, which is perhaps the widespread distribution among Renault gasoline engines. Installed on renault cars: Megane, Logan, Sandero, Kangoo, Fluence, Scenic, Clio 2, Duster, Laguna, as well as on Nissan Almera. G11 I. Lada Largus.. The force aggregate It was created on the basis of the previous motor - K7M, but unlike the predecessor, received 2 lightweight camshafts (respectively, and 16 valves), as well as other pistons and hydrocomathers. Motor has received its further constructive development on Nissan cars for which the H4M engine (HR16DE) was created.

The K4M engine has a lot of modifications that are unambiguously identified to complete the engine labeling (numbers and letters after the engine code). For example, a motor that is sold from us has a label "Renault K4MD812" engine. This means that the power unit is equipped with phase regulators, and completed with mechanical box Transmissions. Some motors are not equipped with phase regulators, the degree of compression and engine firmware are distinguished. Therefore, in the market you can meet the K4M engines with the spread of power indicators - from 102 to 115 hp.

Features of operation and resource

The main operational lack of K4M engines is a relatively short term of the timing belt. According to the recommendations of the manufacturer's manufacturer, the Rules for replacing the GDM should be carried out once every 60,000 km of run or 1 time in 4 years. In this case, the cost of spare parts required for this procedure on a 16-valve motor is sufficiently high. Together with the GDM kit, the water pump usually changes, although it is definitely the need to replace this node can be determined only after disassembling the drive of the gas distribution mechanism. An interesting feature associated with the K4M engine is that the rules for replacing the timing belt for car Lada Largus, installed in 120 thousand km, although the engine itself, and the components are absolutely identical. In this regard, many owners of Lada Largus change the timing set more often of the regulations, and vice versa - Renault holders sometimes pull this procedure, justifying this AvtoVAZ recommendations. In any case, it is not recommended to tighten with this procedure, since the scope of the timing belt on the K4M series motors clearly leads to the valve fad and necessity overhaul.

The frequency replacement of the timing belt with interest is compensated by the resource of the engine. These force aggregates easily overcome a run of 400 thousand km (naturally, with proper care and not loaded operation).

Fuel consumption is approximately 8.5 liters in a mixed cycle. For the route, this figure is 6.7 liters, which is quite a bit, but in the city, the 16-valve can "eat up" to 12 liters of gasoline per 100 km. By the way, K4M without any consequences "digest" Russian 92nd gasoline, why it is so popular in Russia.

Typical engine malfunctions K4M

Among the most common problems of the K4M engine can be listed:

• motor often Troit. This is usually associated with a malfunction of the ignition coil, nozzles or candles, but may mean problems with the mechanism of gas distribution or piston groupTherefore, it is worth starting diagnostics from measuring compression.
• floating turns. A typical malfunction is most often solved by the diagnosis and replacement of the ignition coil or the crankshaft position sensor, or with a factor of the K4M phase regulator.

In this, perhaps, the list of typical K4M engine faults can be finished, since by and large, the motor is reliable and the owner does not deliver special trouble.

Renault K4M 1.6 16V engine is used to install Renault Logan 1.6, Renault Sandero 1.6, Renault Megan 2 and 3, Renault Lagoon, Renault Scenic.
Features. The main difference engine Renault. K4M from and this is the head of the cylinder block with two camshafts for intake and exhaust valves (GBC 16V). Cylinder block, crankshaft, Flywheel K4M and K7M are identical. The engine is produced with a phase regulator (115 hp) and without it (102 hp). Unlike eight-smelled engines, K4M works quieter (including due to the presence of hydrocompensators), it is more elastic, it is more powerful and more economical. The engine resource is still high - 350-450 thousand km. It is worth paying more attention to the fuel filled, due to poor-quality gasoline, turns on idlingThere are failures on the go.

Malfunctions and engine repair K4M

Engine Renault Logan. K4M 1.6 l. 102 hp Not new, a number of different modifications are used. company Renault. Since 1999, on the Renault Megane, Renault Clio II, Renault Laguna models and others. Represents development K7m. Series, with new GBC, already 16 valve. Differences Many: Another head with two camshafts, lung camshafts themselves, other pistons, hydrocomathers, etc. Motors are like a phase management, and without it, the compression ratio varies from 9.5 to 10, with this and the firmware is associated with a small scatter of engine power indicators, and the rest of the K4M is identical. A whole list of indexes after the name K4M shows: toxicity standards (Euro-3 \\ 4 \\ 5), type of check-in, presence of a phase management, compression ratio and other trivia associated with a feature of the installation in each particular car. In nature, there is a modification of a given motor called K4M RS, on wide shafts, sawdwood, it gives 135 hp. with a volume of 1.6 liters.
By cons of 16 valve motors, we will take the highning of the spare parts, the timing belt K4M when the flap of the valve turns, therefore, once in 60 thousand km, you need to change the rollers, belt and ridewith a calm soul. In addition, there are failures in the work, turns are floating from poor quality fuel. Compared with 8 valve Engine, 16V works quieter, more economical, no vibrations and many other advantages. If you choose with which engine to take Logan / Sandero / Largus, then definitely 16 valve K4M your choice. In the case of cars more - Duster, Megan, etc. look at 2.0 liter motor .
It is worth saying about frequently occurring faults, the engine K4M is not rarely troit, the problem is usually in the ignition coil, nozzles, candles, measure compression and proceed already from this.
Unstable, floating turns on K4M Logan 1.6 Engine are usually caused by the crankshaft position sensor or the ignition coil.
Since 2006, a successor to K4M has been produced, called H4M, on Nissanovsky labeling HR16DE, look for details about it.

Renault K4M 16 Valve Engine Tuning.

Chip tuning, engine firmware K4M 1.6 16 valves

An ordinary engine chipovka, simultaneously with the replacement of the exhaust on the barn, is able to slightly improve the danimic indicators of the motor, + \\ - 120 hp Get quite possible. You can supplement it. You can install the drives of the drive 10 phase 270, a little wider than the standard, go a little more fun and gives some more hp. To move on, you need to come up with something else.

Compressor on Renault K4M

Exactly as on K7M or K7J., with a big desire, the Motor can be attached to the PC-23 compressor and inflated about 140-150 hp. The degree of compression of standard K4M is not too high, 0.5 bar will withstand. There are no ready-made whales on this motor, but by contacting the manufacturer, you will collect the desired configuration for a specific car. To implement the project, you will use Volgov nozzles, straight-flow exhaust, shafts phase 270-280, and to configure all this online, the ABIT motor control unit will be required.

Turbine on Renault K4M 16 valves

System 1 in 1 as a compressor, only instead of PC-23, we put the turbine TD04, all the nozzles, shafts, etc. We put the same thing. In practice, such configurations give a little over 150 hp. It will be difficult to get outstanding dynamic indicators, but the fact that the car will go faster for sure. As for the resource ... Someone thinks about the resource when it comes to superfluous? 🙂

Today in many countries of the world, including the Russian Federation, in large quantities there are cars Renault, Logan, Sandero, Megan, Almera. What could be common between these models? This machines installed the K4M engine. This power unit has proven itself from a positive side.

Many specialists, owners of these machines, characterize it as a reliable, economical motor. It is a logical continuation of such a line of engines as K7M, which has received minor constructive changes.

What does he represent

This power unit serves as a base for several models of machines of various manufacturers. The K4M motor is a motor having a volume of 1600 cm 3, in which 16 valves are installed in the GBC. As fuel mixes Gasoline is used, installed on recent models Renault, as well as LadalarGus, Nissanalmera.

To the main differences that Motor K4M from the K7M version can be attributed to new version Head of BC. She received two camshafts separately for intake and release valves.

This is reported by the inscription 16V on the body of the machine, as well as on the head of the cylinder block. If we consider the design of the cylinder block, the crankshaft, then they are the same for both versions of the motors. The Renault Logan 1.6 engine may have a phase regulator for models, the power of which is 115 hp, or such for motors with less power.

The owners note a slight decrease in the noise of the working power unit, this contributes to the hydrocomathers in the gas distribution mechanism of the power unit.

A few words about the engine design

The design of the DVS has four cylinders, the operating cycle consists of four cycles. Works on gasoline, the power system has a block for electronic control of fuel injection, ignition. The motor device has an inline arrangement of work cylinders with pistons. Their rotation is carried out in one crankshaftwhich also transmits rotation to two camshafts.

The system for cooling the closed type motor has a forced circulation. Antifreeze is used as coolant. The lubrication system was performed by combined, that is, the engine oil is supplied to the friction places under pressure, as well as spraying.

For the manufacture of the cylinder head of 1.6 16 Motor valves K4SU use aluminum alloy. The gas distribution mechanism drive device is designed in such a way that the rotation of the camshaft is carried out using a toothed belt.

Their rotation through the rocker and the hydrocomathers are transmitted to intake and exhaust valve. The simplicity of such a design has one significant disadvantage. When the toothed belt is climbing or other damage to its working area, the valve piston jets.

Valve of this motor have different sizes Not only for plates, but also their lengths. Inlet valves have big sizesboth plates and their length. In this motor, the connecting rods are made of steel by forging. Piston K4M differ from K7M with its originality, they are produced with a diameter of 79.465 to 79,475 mm. The mass of such a product is approximately 450 grams.

Little Motor Maintenance

Any DVS, including K4M, needs periodic maintenance. The regulations for conducting such work in detail in detail in the instruction manual for the car, but it will not be superfluous to recall this again.

First of all, it should be reminding that special attention should be given the state of the toothed belt, tensioner rollerother elements of the drive mechanism of gas distribution. Otherwise, during damage to these parts, the valve can be brought, and these are the significant costs of repairing the power unit. Replacing these products should be made when running 60 thousand km of run.

Important! Especially dangerous for a toothed belt hitting its surface motor oilThe slightest leaks should be eliminated immediately.

The next factor requiring the close attention of the driver of the machine with the K4M engine is timely replacement Motor oil. On the frequency of such an operation also informs in detail the instruction manual vehicle. Choosing oil to replace the regulations, buy those stamps that manufacturer recommends.

According to the regulations, the replacement of motor oil is made when running 15 thousand kilometers of a run or one year of operation of the machine. If some pouring oil into the engine can be found from the instruction, then where to produce such an operation or where the lubricant is not specified.

If there is a little experience in maintaining the machine. You can perform such an operation on your own.

The plant is poured with 5W40 or 5W30 oil, try to apply the same for your car. High quality manufacturers motor lubricants Many, properly approach their choice and your car will be a long period to "run" without problems. If the replacement of lubrication is made in conjunction with oil filterOils will be required about 4.8 liters, if without a filter, there will be enough 4.5 liters enough.

In order for the resource of the engine fully, it is impossible to forget about its nutrition and breathing. This fully refers to fuel and air filter in the gasoline supply system. By regulations air filter It is subject to replacing about 30 thousand km of run or after two years of operation.

But here can be their own characteristics that depend on what conditions the machine is operating. If it occurs in high dusting conditions, the air filter should be changed more often.

If we talk about gasoline, then there are our pitfalls here. Unfortunately, today you can still meet gas stations that offer gasoline dubious quality. The use of poor-quality fuel can completely remove the power unit in order, which will result in significant financial costs for its recovery. The manufacturer recommends using gasoline, the octane number of which should be at least 92 units.

Tip! If you have to add fuel to an unknown gas station, fill it with its minimum amount so that you can reach the refueling you know and add high-quality gasoline.

What else to know

When operating the engine K4M, the spark plugs play an important role. The manufacturer makes recommendations on which candles are suitable for this motor. The plant is set to products that have a catalog number 7700500155, but you can also use Eyguem, RFC58LZ2E, SageMRFN58LZ, CHAMPIONRC87YCL.

The K4M engine is the development of the K7M series.

Double-liter gas engine Renault is set to numerous models of this French automaker. There are several options for motors, which, depending on its modification, are issued from 102 to 138 horse power.

All modifications of this motor have interchangeable parts, with the exception of the forced version, which is installed on CLIO Sport. This F4R engine in the forced version can develop power in 180 horsepower.

Specifications

The K4M engine has the following specifications:

K4M engines are installed on Renault Logan, Sandero, Kangoo (1 and 2), Duster, Megane (1, 2, 3), Clio 2, Laguna (1, 2), Scenic, Fluence, Lada Largus and Nissan Almera G11.

F4R engine is installed on: Renault Duster., Megane 2, Laguna, Espace, Clio Sport.

Description F4 R.

Starting with gray. 1980, Motors in Renault are indicated as XNY ZZZ:
X is a series of motor;
N is a digit that denotes the engine architecture (4 - for gasoline power units with 4 valves per cylinder; 7 - gasoline motors with distributed injection and 2 valves per cylinder; 9 - diesel with immediate injection);
Y - letter denoting a worker;
ZZZ is a number indicating any features of the design (for example, non-venerable numbers indicate cars with an automatic transmission, which are measured with mechanical).

Double-liter (F4 R) Renault engine, 135-138 horsepower, has a belt drive, which slightly reduces the reliability of the power unit.

French engineers, though developed a fairly reliable drive system, but the timing belt clips are not uncommon on this motor, which leads to the need for expensive overhaul engine Renault Logan. Such overhaul can be performed solely using the appropriate equipment and experienced masters.

The feature of the Renault Logan engines is the gas distribution system used, which allows you to optimally adjust the operation of intake valves. The Renault Logan engine has 16 valves, each of which is controlled by electronics. Adjusting the lifting height of the valves is performed using a special phase management, which in milliseconds is able to analyze data from different sensors.

We only note that this phase generator of the engine Renault Logan is due to the increased load, which falls on it during operation, can often fail. On average, the resource of this spare part is 50-70 thousand mileage kilometers.

Service

• Given that properly operation Motor will require opening no more than once in 100 thousand kilometers. However, if the auto owner will neglect the requirements of software, this can lead to serious breakdowns literally after 50 thousand mileage kilometers.
• Availability of U. online engine The volume of 1.6 liters of two camshafts improves the characteristics of the motor, eliminating vibration simultaneously and making it work as much as possible.
• The Renault Logan engine itself is minimal noise and provides excellent comfort while driving at different speeds.
• We also note the use of fuel injection injection, which makes it possible to improve environmental indicators and reduces fuel consumption. This power unit, despite the widespread use of various automated units and a modern injection system, is able to work at 92 gasoline, which reduces the costs of the car owner.
• Renault Duster Engine is a virtually modernized version of the four-cylinder engine, which was successfully produced for 10 years. The use of such a reliable and proven year of the structure of the power unit made it possible to ensure the most reliable operation of the motor.

Subject to the service interval, the Renault Duster engine has a resource of about 400 thousand kilometers. A similar design has a K7J engine installed on Renault Logan and Sandero. These motors have interchangeable parts and differ simplicity in repair.

• In comparison with its predecessor, the Renault Duster engine received an upgraded production system and fully automatic control work of the power unit. By reconfiguring the control unit, you can change the power parameters and thrust of the F3R engine, so it is equal to the same success on both compact cars and a Renault Duster crossover.
• The control of the control unit allows you to significantly increase the torque on the duster, which is positively affected by the vehicle's passability and its controllability on the country road.
• The F3R engine has a simple design, which significantly simplifies its subsequent repair, which can be performed in any hundred. The need to overhaul the engine F3R occurs during runs more than three hundred thousand kilometers.
• The manufacturer recommends regularly replacing the timing belt, which is required every 50,000 kilometers.
• Renault Logan oil is recommended to change every 10,000 mileage kilometers. It is recommended to use the original semi-synthetic oil And to carry out all service events for sure.
• The F4R cylinder block is cast from cast iron, however, due to the use of aluminum for GBC and compact dimensions, this power unit has a light weight, which has a positive effect on the car manageability.
• Depending on the modification of the car, which is installed by the Renault Duster engine, its fuel consumption indicator can vary from 7 to 10 liters of fuel per 100 kilometers of the mileage. When installing on a car automatic box Gear fuel consumption can slightly increase.

Fault

Tuning

1. A variant is possible with a flashing F4R control unit, however, such work will allow you to get 5-6 additional horsepower from the strength, while the cost of such tuning will be high enough, and the F4R engine will start unevenly on low revs.
2. If you need to increase the power of the Renault Duster engine, we can recommend using a whale kit from K7m K7m Clio, which includes reinforced camshafts, engine supports, forward flow and installing a new firmware. All these works allow you to obtain the power of the F4R motor in the area of \u200b\u200b170 horsepower. In this case, any deterioration in the reliability indicators of the Renault Duster engines is not marked. Remember only that these work should conduct experienced motorists.

An additional turbocharging on the F4R would not be recommended to you, since in this case the resource is significantly reduced, which may require major overhaul after 100 thousand kilometers. Yes, and the installation of turbo will allow you to raise the power to the maximum of up to 200 horsepower. In this case, the F4R engine may require overhaul after 50-100 thousand mileage.
