Very often I have to read questions - "Tell me about the Hyundai Solaris and Kia Rio motors, they are reliable or not, how much are (resource), what problems are, pros and cons and so on." After all, these Korean cars are one of the best-selling and very big interest. For a long time I did not write this video (I thought everything was said before me in hundreds of videos and articles), but readers want my opinion, so today I decided to write. As usual will be the video version at the end ...

It is worth noting that these power units are standing on most other Korean cars class above, such as Kia Ceed and Cerato, as well as Hyundai Elantra., I30 and Creta. They are also common in Russia, and therefore the information will be interesting and their owners.

For impatients I want to say one thing - these engines are reliable as a hammer, there are no more frequent problems with them - no. You can safely take.

But for those who want to learn more about the motors of these Korean units, read on.

What motors put?

Let's start with old cars (2010 - 2016 releases), there are only two power units, generations. Gamma 1,4 liters (107l.s.) and 1.6 liters (123 hp)

At the moment (since 2017), that on Solaris, that two engine options are installed on Rio - these are the so-called Kappa (volume of 1.4 liters - 100 hp) and Gammaii (1.6 liters - 123 hp) .

The Kappa generation began to be installed on the "poor" versions of the new generation of cars only in 2017, in high grades there is a changed engine Gammaii (unlaspped name)

EngineGamma (G4.Fa I.G4.Fc)

Perhaps, I will start with the description of these engines, as well as with the characteristics of the structure (the analysis will be very detailed, so stock tea):

Where they produce: The plant is in China (Beijing Hyundai Motor Co). Often to this country is a very biased attitude that "mole" is all poor quality and so on. However, it is not worth confused by the underground and factory production (this is a huge difference). And so on the passage of the iPhone, too, in the subway.

Fuel supply system recommended gasoline and compression ratio : Injector, distributed injection (MPI). I think this is a plus, because this system is very simple, nozzles do not have contact with combustion cameras (like the GDI direct injection), here they are built into the intake manifold. They have a cost of cheaper, the pressure below (there is no analogue of the TNVD), and you can clean them yourself. In general, I advise you to read, everything is simple in her fingers. Gasoline can be poured, works perfectly on it (this is another plus). - 10.5.

Engine block : I will not attempt for a long time now - yes he is aluminum with thin-walled dry sleeves from the cast iron (they are inserted at the time of production). As many "shouting" (in various forums) that the power unit is disposable and that "MOL" rode 180,000 km and all throw out (a little later). However, as practice shows, these motors are perfectly repaired. There are a bunch of rollers on the Internet, where these old worn sleeves are thrown out and new ones are put on their place (and further piston and so on). So Russian masters can a lot - this is a fact!

Cylinders, pistons, crankshaft: 4 pieces in a row, pistons Lightweight oiling and compression rings of normal sizes (although they could be thicker). Crankshaft And his liners do not cause any complaints, go for a very long time (this node is not a problemal link)

GRM system : On the engine of Solaris - Rio, two camshafts are installed, 4 valves per cylinder (that is, 16 valves). - No, only pushers are installed. It is worth, with a hydraulic "tensioner" chain. There is one, standing on the inlet shaft.

: Intake - plastic, with the inlet geometry change system (VIS). Graduation - stainless steel. In essence, everything is very simple.

Butter: It is allowed to replace every 15,000 km, recommended synthetic 5W30, 5W40. The volume is about 3.3 liters. Operating temperature - 90 degrees Celsius

Resource declared by the manufacturer : about 200,000 km.

Differences of motors 1.4 and 1.6 liters : Weak version wears abbreviation G4. Fa (1.4l-107) , the older version is known as G4. Fc (1.6l-123) . Engines are practically identical, the difference is only that powerful version Piston stroke - 85.4mm, and in a weak 75mm (different crankshaft). Thus, "1.6" just sucks a larger amount of fuel - everything else without change (it will be very detailed in the video version).

DifferenceGamma I.Gammaii (G4FG)

As I have already written above, the generation of GAMMA engines was raised not only on Hyundai Solaris and Kia Rio, but also on Ceed, Cerato, Elantra, I30 and say Creta. That's just if there was a 123 hp on Solaris (Rio), then let's say on various "sits", "Elantrah" and other C-grade was 128-130 hp. Why is that?

Everything is simple:

There is a distinction for both Gamma and Gammaii, motors:

Gamma. - these are power units with one phase displayer on the inlet, 1,4 liter volumes (code designation G4FA.) and 1.6 liters ( G4FC.).

Gammaii. - Until 2016, they were installed only on Ceed, I30, Cerato, Elantra, etc. (Swim power from 128 to 130 hp). Since 2017, it is also installed on Solaris, Rio and Creta (the power is artificially understated until 123l.s.). The only difference is that there are two phase masters on both shafts, the volume is 1.6 liters (code designation G4FG.). Otherwise, the design is identical

In the dry residue - since 2017, the motors on solaris and Rio became other (both on Elantra, Sids and others), both 1.4 and 1.6 liters. Let not be critical, but they differ.

Pros, cons and resource

In probably, from the resource - it will be the first plus . The manufacturer gives about 200,000 km, but now there are cars since 2010, which have already passed 500 - 600,000 km and you know, the motors work, despite anything (no matter how they scold them).

Really aggregates are fragile And often it is often not at the best 92 gasoline. It is worth noting a convenient location, you can only get there and easily replace (candles, air filter), intake and exhaust manifold, engine cushion. Short inlet, and this is not unavailable (than it is shorter, the less pumping losses for suction). There is also no such large volume of plastic as many modern motors. The main thing is to serve on time (yet I recommend changing the oil once every 10,000 km), pour high-quality synthetics (still there is a phasemator and chain tensioner), well, and pour 95 gasoline.

In minuses (Although it is not cons, but my recommendations). The noisy operation of fuel injectors is not mortally, but the fact (it seems not the rigging chain). There are no hydrocompensators (there are ordinary pushers) they need to be changed (by selecting new height) approximately every 100,000 km. Chain mechanism, and the timing chain itself is also desirable to replace up to 150,000 km. Sometimes there are (he simply can crumble), the baby falls into the cylinders and can very quickly kill the motor. The problem is not massive, but it happens how dealers are assigned from low-quality fuel, so refuel on normal gas stations

If you summarize the Motor G4FA or G4FC, G4FG - then they really have a large resource now. As one motorist told me - "Reliable as a hammer and that not all the Japanese do so now." That is why they are so loved by many taxi.

EngineKappa 1.4.MPI (G4LC)

As I think this is a continuation of GAMMA engines, however, Kappa has their own chips. Code name G4. LC . Before installing on Solaris and Rio, this engine was installed on Hyundai i30 and Kia Ceed.

Power : The very first thing worth noting, its number horse power - 99.7 hp (It is written in the nomenclature that 100 hp). This is done specifically for tax, because in earlier versions of Ceed and I30 such motors developed about 109 hp. So after the purchase you can restore the justice of the factory firmware () from Korea

Where is going : According to the latest information, they are shipped directly from Korea (about China talking does not go).

Fuel supply system, gasoline, compression ratio: Here, the distributed fuel injection (MPI) nozzles is installed in the plastic intake manifold. Gasoline at least 92. compression ratio of 10.5

Engine block: Aluminum with dry cast-iron sleeves. In essence, the design similar to Gamma, however, the KAPPA block is facilitated by 14 kilograms, compared with the predecessor! This causes alertness, the motors are "thin", and here there are still 14 kg from somewhere.

Cylinders, pistons, crankshaft: 4 - cylinder, located in a row. Pistons are even more facilitated than the predecessor. However, how does the manufacturer assure piston cooling nozzles - It is really plus. Rolling rods are thinner, but they are longer. The crankshaft is similar to G4FA and G4FC, but according to my neck, a little already. Again, relief in everything is not very good.

GRM: 16 valves (4 per cylinder). Again, there are no hydrocompensators, there are ordinary pushers. But there are two phase displayers on intake and graduation raids (D-CVVT). There is a lamellar gear chain.

Intake and exhaust manifold : As usual intake - made of plastic, with the inlet geometry system (VIS). Graduation - stainless steel, with a catalyst built into it.

Lubrication: You need to pour 5W30 or 5W40 synthetics, it is allowed to replace 15,000 km (the volume is also about 3.3 liters). Works at a temperature - 90 degrees Celsius.

Manufacturer's resource - about 200,000 km.

Pros and consKappa.

If you compare G4LC and G4FA (1.4 liters), then the generation of KAPPA maximum power is achieved at 6000 rpm. Whereas Gamma at 6,300 rpm. Reached it by a longer piston stroke:

Gamma1.4. , stroke-75mm, diameter-77mm

KAPPA1.4. , stroke-84mm, diameter-72mm. That is, it is less, but walks more.

Even pluses are good fuel savings (up to 0.2-0.3 liters per 100km, if compared with the opponent) and the elasticity of the engine, it is also there are two phase displayers. Well, the weight loss by 14 kg, also gives advantages in overclocking and fuel consumption.

Here are also worth the metal chokes, thermostats, there are cooling of cylinders in nozzles. With due service (changing the oil after 10,000 km and pour good), more than 250,000 km walk (it is proved by operating I30 and CEED). By the way, it is put on Rio X-Line now

The minuses can be called relief of all and all, especially block, rods, pistons (by 14 kg). Of course, "" is also possible (folk craftsmen), but will be more accurate and difficult. Again noisy noisy, it's just a design specificity. We change the pushers every 100,000 km and the chain mechanism of 150,000 km (although it is not expensive, according to modern standards). As on many modern cars, there may be problems with jams from the catalyst (but this is not a claim to this power unit).

The motor also turned out to be successful, and he picks up much faster than the opponent, it goes easily to 250,000 km and practically nothing problems with proper care.

Now we look at the video version of the article, I think it will be interesting.

If you summarize - it can be said that any 1.4 or 1.6 liter motor on machines Hyundai Solaris., Elantra, I30, Creta, as well as on Kia Rio, Rio X-Line, Ceed, Cerato - Walk without any problems, often just huge runs of 500 - 600,000 km. Take, do not be afraid.

Owners of budget vehicles useful to learn the features of the power units installed on cars Kia. RIA. The upcoming study is devoted to the advantages and disadvantages of these engines, recommendations for proper maintenance and content. The proposed publication will help determine suitable fuel and oil.

Not every driver can afford a business class car from leading European manufacturers. Most are content with small, choosing domestic cars.

There is another one a budget optionprovided to the Russian market of Korean vendors of automotive equipment. This article will tell, what is the engine Kia Rio in reality, and what measures will help the owner to maintain the original characteristics of the unit for a long time.

Characteristics of the power plant Kia Rio

Korean manufacturers took care of the convenience of Russian motorists. Their creation is great for domestic roads. This is facilitated by the following characteristics. power aggregate:

• the possibility of refueling gasoline AI-92. For most budget owners vehicle The issue of saving is in the first place, so the use of low-cost fuel is important;
• in difficult conditions russian roads A special anti-corrosion composition is very useful, which protects the bottom of the body from exposure to domestic dirt;
• the harsh climate is not a hindrance to start the engine. The developers have provided the ability to start a motor at temperatures to -35 0 C. Therefore, the car perfectly established itself even in the conditions of the northern regions;
• domestic communal services are struggling with icing winter roads, richly sprinkled with salt. Korean manufacturers secured the radiator, protecting it with a special composition that protects from such turmoil.

It should be noted that at Kia Rio, the installation of power units of two types, differing in volume and power. Each of them requires separate consideration.

Features 1.4-liter motor Kia Rio

To begin with, we note that this power unit is basic. Its feature is considered to be the ability of 6300 revolutions per minute to develop the power of the engine, which is equivalent to 107 horsepower. Taking into account the use of AI-92, this is a very good indicator. The mechanical transmission allows only 11.5 seconds to reach a speed of 100 km / h.

On the open highway, such an engine consumes only 4.9 liters of fuel. Riding on the city streets increases the absorption of gasoline to 7.6 liters. Moving in a mixed cycle is characterized by a fuel consumption of 5.9 liters.

In another measurement system, 1.4 l corresponds to the volume of 1396 cm 3. The engine has four acting cylinders. Each of them has 4 valves. The working stroke of the piston is determined by the value of 75 mm inside the cylinder with a diameter of 77 mm.

Finally, we note that fully using the resource engine Kia. Rio, the driver is able to develop speed up to 190 km / h. Such indicators are very acceptable for domestic motorists who prefer quick riding with minimal fuel costs.

Features 1.6-liter engine

A relatively small volume, however, allows the power unit to develop the power of the engine, comparable to the efforts of 123 horses of horses. This allows the driver to feel unshakable confidence in the reliability of the vehicle.

Personally, I lie into the gas tank of such an engine exclusively AI-95. In this case, save, refueling cheaper fuel, it is very unreasonable because it may adversely affect performance features Motor for Kia Rio.

The next distinguishing feature of the engine equipping Kia Rio is the TRG drive represented by a chain mechanism. This greatly simplifies the replacement process and increases the durability of the device. Although the chain timing and helps to increase some rigidity of driving and noise in the cabin, these disadvantages are completely compensated by the growth of reliability and endurance of the force aggregate.

When driving around the city, a 1.6-liter engine consumes approximately 8 liters of fuel. If you intend to take a journey through an open track, the fuel should be pouring into the tank at the rate of 5 liters. It is somewhat more difficult to determine how much gasoline needs when driving on the combined type of terrain. Experienced drivers for a mixed cycle are 6.6 liters.

Dynamic indicators of the engine are similar to the previous model. Only the magnitudes of the piston stroke and the diameter of the cylinders are distinguished. For power plant 1.6 l They make up 85.4 and 87 mm, respectively.

Motor shortcomings 1.6 l

Possessing a sufficient number of positive characteristics, the model of the motor has also has a rather substantial flaw. They deserve a separate mention:

• limit space motor compartment With a sufficiently large engine size makes it very problematic access to some nodes. Therefore, to renovate certain details can only after additional dismantling of the power plant;
• since the engine temperature in operation has quite high indicators, problems may occur due to the material of the manufacture of the cylinder head. As is known, aluminum is bad to carry thermal overvoltages. However, this flaw is compensated for by the production capacity of the technological alloy;
• ignition and gas distribution systems are subject to replacement only in the kit. It simplifies overhaul engine, reducing labor costs, but makes it impossible to partially replace parts of the indicated mechanisms;
• perhaps the most significant disadvantage of the underlying power aggregates is considered low maintainability. Even professionals specialized Services With a huge reluctance taken for overhaul after damage to the main nodes.

Listed flaws do not diminish the indisputable advantages of this motor. They should also be considered more detailed.

Advantages of the power unit 1.6 l

Most modern motorists prefer to acquire cars with such an engine. When choosing the following positive sidescharacterizing the motor:

• savings by low fuel consumption. Moderate ride on the combination cycle route requires only 6 liters of fuel. Personally, I always lens gasoline from this calculation;
• the extreme reliability of the main functional nodes is attractive, which ensures the trouble-free operation of the KIO RIO sedan engine for more than 200 thousand kilometers;
• high dynamism, characterized by the possibility of overclocking up to 100 km / h in just 10.3 seconds;
• the optimal distribution of the characteristics between the engine and the transmission creates an excellent elasticity of the power plant. This instills confidence to the driver in the most difficult road situation.

Despite some difficulties caused by the inability partial replacement Certain elements of the gas distribution mechanism and the ignition system, for professional mechanics of specialized service workshops, the repair of the engine Kia Rio is quite familiar. A fair service is considered fairly acceptable.

The exclusiveness of the resource of the power unit is confirmed by the owners of cars, which over a five-year period overcame more than 300 thousand km. A wonderful fact is that in the sedan did not show any tangible engine problems.

The manufacturer provides for the need technical inspection After passing every 10 thousand km. Even medium wealth car owners may well afford to use the services of specialized workshops. The available cost of service is explained by the simplicity of the structure of the power unit.

There are several secrets capable of increasing the motor resource:

• the term of the reliable service of the car largely depends on which oil is poured into the Kia Rio engine. It is recommended to choose the brands of proven manufacturers, without taking into account the seasonality of petroleum products. Also should be updated regularly motor oil For Kia Rio, necessarily replacing with this oil filter. Manufacturers have a maximum mileage on the same lubricant, determined by 15,000 km. However, experienced drivers try to change the petroleum product every 7000 km;
• gasoline should be poured exclusively on specialized gas stations. This will help exclude the use of poor-quality fuel. Cheap counterfeit fuel can quickly deal with a fully effective power unit;
• the last board concerns the driving style. The calm measured ride will save the car much longer than the car rather than.

Engine Kia Rio 1.6 Litra issues 123 hp At 155 nm of torque. The Power Aggregate Gamma 1.6 liters came to replace the Alpha series engines in 2010. A power unit has been developed by the Korean Concern Hyundai and is established on a variety of promotional models. The power unit has shown himself in our market, as a reliable and unpretentious motor.

To date, this Motor Kia Rio has several modifications with a variable gas distribution phase on the shaft inlet, with a double phase change system on both shafts, with a distributed fuel injection MPI, with direct fuel injection. Based on this atmospheric motor, the Korean Concern is even a version with turbocharged. Naturally, each modification has its own power indicators and fuel consumption.

Kia Rio 1.6 Engine Device

Kia Rio 1.6 engine It is an inline 4-cylinder, 16 valve unit, with an aluminum cylinder block and a timing chain drive. The inlet shaft is the actuator mechanism for changing the phases of gas distribution. Distributed fuel injection with electronically control. In addition to the aluminum block, the block, the crankshaft pastel and pallet is made of the same material. Refusal to use heavier cast iron made it possible to make it easier to facilitate the entire power unit.

GRM drive Kia Rio 1.6 l.

Hydrokompensers at the new Motor Rio 1.6 is not. Valve adjustment is usually carried out after 90,000 kilometers, or if necessary, with an increased noise, from under valve cover. The procedure for adjusting the valves is to replace the pushers that cost between valves and camshafts. The process itself is not easy and not cheap. The chain drive is very reliable if you monitor the oil level.

Engine characteristics of Rio 1.6 liters.

• Working volume - 1591 cm3
• Number of cylinders - 4
• Number of valves - 16
• Cylinder diameter - 77 mm
• Piston stroke - 85.4 mm
• Power hp - 123 at 6,300 revolutions per minute
• Torque - 155 nm at 4,200 revolutions per minute
• Compression ratio - 11
• GRM - chain
• Maximum speed - 190 kilometers per hour (with automatic transmission 185 km / h)
• Acceleration until the first hundred - 10.3 seconds (with automatic transmission 11.2 sec.)

• Fuel consumption in the mixed cycle - 5.9 liters (with automatic transmission 7.2 liters)
• Fuel consumption on the highway - 4.9 liters (with automatic transmission 6.4 liters)

It is already known that the next generation Kia Rio will receive an upgraded version of this engine. A double phase change system and an intake manifold with a variable geometry will appear. True, it will not affect the capacity, but the fuel consumption and exhaust toxicity can be reduced to lower. The engine is fully adapted to the consumption of gasoline of the AI-92 brand. The same

Cars Kia Rio. For the Russian market, equipped with transversely located four-stroke four-cylinder gasoline injection 16-valve DOHC CWT engines with a working volume of 1.4 and 1.6 liters. Appearance The engines in the composition of the power unit are shown in the figures below.

Engine Kia Rio (front view): 1 - bracket fastening the right support suspension of the power unit; 2 - Drive Belt auxiliary aggregates; 3 - generator; 4 is a beggaging valve of a gas distribution system (CWT); 5 - the tube of the oil-filling neck; 6 - Cylinder head cover; 7 - oil level indicator (oil-metering probe); 8 - fuel ramp; 9 - inlet tube; 10 - Cover candlestones; 11 is the camshaft position sensor; 12 - throttle assembly: 13 - water distributor; 14 - switching and gear selection mechanism; 15 - gearbox; 16 - Crankshaft position sensor; 17 - starter; eighteen - oil Carter; 19 - pressure sensor run; 20 - oil filter; 21 - cylinders block; 22 - pointer guide nala; 23 - thermostat case; 24 - the plug of the oil-flow hole; 25 - Pallet Oil Carter.

Both engines are almost completely the same in design and differ only in the radius of the crankshaft crankshaft (different piston stroke: the engine is 1.4 liters - 74.99 mm, and the engine is 1.6 liters - 85.44 mm) and the block height Cylinders. In this regard, all the operations on the repair and maintenance of the engine in this section are described on the example of the engine with a working volume of 1.6 liters. Work on the engine with a working volume of 1.4 liters is completely similar.

Engine operating volume (liter) - one of the most important design parameters (characteristics) internal engines combustion of DVS), expressed in liters (L) or cubic centimeters (cm3). The operating volume of the engine largely determines its power and other operating parameters. It is equal to the amount of working volumes of all engine cylinders. In turn, the working volume of the cylinder is defined as a product of the cylinder cross-section area for the length of the piston working stroke (from NMT to BMT). According to this parameter, long-time engines are distinguished with a length of the piston code greater than the diameter of the cylinder, and the short-spectacular piston is less than the diameter of the cylinder, so when the cylinder is diameter is 77.0 mm, and the engine is 1.4 liter for both engines, and 1, 6 l - long-purpose.

Engines - with row vertical location of cylinders, liquid cooling. Engine switchgears are driven by chain.

A distinctive feature of the engine car Kia. Rio is the presence of him electronic system Changes in gas distribution phases (CWT), dynamically regulating the position of the inlet camshaft. This system allows you to establish the optimal phases of gas distribution for each moment of operation of the engine, resulting in increased power, the best fuel efficiency and less toxicity of exhaust gases.

The gas distribution phase change mechanism, mounted on an intake switchgear, by the electronic engine control unit, turns the shaft to the desired angle in accordance with the engine mode.

The mechanism of changing the phases of gas distribution is hydraulic mechanismconnected to the engine lubrication system. Oil from the engine lubrication system enters through the channels in the gas distribution mechanism. Rotor 2 (Fig. Below) turns camshaft By command of the engine control unit.

Mechanism of changing phases of gas distribution: 1 - body of the phase change mechanism; 2 - rotor; 3 - Oil Canal.

To determine the instantaneous position of the camshaft, a camshaft position sensor at the rear of the camshaft is set. The camshaft holder is located on the cassetting of the position sensor ring.

A solenoid valve, a hydraulically controlling mechanism, is fixed on the head of the cylinder block. Electromagnetic valve, in turn, manages the electronic unit Engine control.

The use of the CWT mechanism provides a smooth change in the angle of installing an inlet camshaft in the position of the early and late opening of the valves 3 of the gas distribution (Fig. Below), the control unit determines the position of the intake camshaft along the signals of the camshaft position sensor and the crankshaft position sensor and gives the command to change the position shaft.

The process of changing the phase of gas distribution: A - installing an intake camshaft to the position of the early opening of gas distribution valves; B - installation of an intake camshaft in the position of the late opening of gas distribution valves; 1 - distribution shaft; Z - mechanism for changing the phases of gas distribution; 3 - electromagnetic valve of the gas distribution phase control system.

In accordance with this command, a spool 2 (Fig. Below) is moved by an electromagnetic valve, for example, in the direction of a larger advance of the opening of the inlet valves. At the same time, the oil supplied under pressure enters through the channel in the housing of the gas distribution mechanism into the CWT mechanism housing and causes a rotation of the camshaft in the desired direction. When the spool is moved in the direction corresponding to the earlier opening of the valves, the channel for later opening them is automatically connected to the drain channel. If the camshaft turned to the desired angle, the spool of the solenoid valve on the control unit command is set to a position in which the oil is maintained under the pressure on both sides of each of the clutch rotor blades. If the distribution unit is required to the side of the later opening of the valves, the regulatory process is carried out with the oil supply in the opposite direction.

Solenoid valve Systems of changing phases of gas distribution: A - cavity connected by the potassium in the cover of the cylinder head with the first working chamber of the hydromeflip of the gas distribution phase change mechanism; B - the cavity connected by the channel in the cylinder head cover with the second working chamber of the mechanism of changing the phases of gas distribution; 1 - electromagnet; 2 - valve spool; 3 - ring duct connected by the channel in the cylinder head cover with the second working chamber of the gas distribution phase change chamber; 4 - Ring Oil Retroxide; 5 - ring duct connected by the channel in the cover of the cylinder head with the first working chamber of the mechanism of changing the phases of gas distribution; 6 - Oil supply hole from the main line; 7 - valve spring; 8 - Oil drain hole.

The elements of the CWT system (solenoid valve and the mechanism of dynamic change in the position of the camshaft) are precisely manufactured nodes, in connection with this when performing maintenance Or repairing a system of changing phases of gas distribution is allowed only to replace the elements of the system assembly.

The head of the engine cylinder block is made of aluminum alloy over the transverse cylinder purge (intake and outlet channels are located on opposite sides of the head), the saddles and guide valve sleeves are pressed into the head.

The engine cylinder block is a single casting from a special aluminum alloy, forming cylinders, a cooling shirt, an upper part of the crankcase and five crankshaft supports. At the bottom of the block, five beds are made of indigenous bearings. Special tides, flanges and holes for fastening parts, nodes and aggregates, as well as channels of the main oil line are made on the cylinder block.

The crankshaft rotates in the native bearings having thin-walled steel liners with an antifriction layer. The crankshaft of the engine is recorded from axial movements with two semicircles installed in the dough bed of the middle indigenous bearing.

The flywheel is cast from the cast iron, installed at the rear end of the crankshaft through the installation sleeve and is fixed with six bolts. On the flywheel pressed the gear rim for starting the engine starter. On cars S. automatic box Gears instead of the flywheel install the drive disk of the hydrotransformer.

Pistons are made of aluminum alloy. On the cylindrical surface of the piston head, ring grooves for the oil-circulation and two compression rings are made, the pistons are additionally cooled with oil supplied through the hole in the top head of the connecting rod and sprinkle on the bottom of the piston.

Piston fingers are installed in the piston bosses with a gap and pressed with tension in the top heads of the connecting rods, which are connected by their lower heads with rod crankshaft crankshaft through thin-walled liners, the design of which is similar to the root.

Steel rods, forged, with a core of a foreign cross section.

Combined lubrication system.

A closed crankcase ventilation system is not reported directly with the atmosphere, so simultaneously with the gas suction in the crankcase, there is a vacuum at all modes of engine operation, which increases the reliability of various engine seals and reduces the emission of toxic substances into the atmosphere.

The system consists of two branches, big and small.

When the engine is running on idling And in low load modes, when the vacuum in the intake pipe is large, crankcase gases through the engine crankcase ventilation system, mounted on the cylinder head cover, in the small branch of the system are absorbed by the intake pipe. The valve opens depending on the vacuum in the inlet tube and thus adjusts the flow of crankcase gases.

In full load modes when throttle valve It is open to a large angle, the vacuum in the inlet tube is reduced, and in the air-powered sleeve increases, crankcase gases through the hose of a large branch, connected to the fitting on the cover of the block head, mainly enter the liner sleeve, and then through the throttle assembly - into the inlet tube and In engine cylinders.

Motor cooling system sealed, with expansion BachkomConsists of a cooling shirt made in casting and surrounding cylinders in the block, combustion chambers and gas channels in the cylinder head. Forced cooling fluid circulation provides a centrifugal water pump with a crankshaft drive with a polyclinite belt, simultaneously leading the generator.
