IN general view Mercedes engine is a long line of both petrol and diesel automobile motors different power and configuration.
One of the founders of the Mercedes-Benz automotive company (now the Daimler A. G. concern) was a German engineer, the creator of the world's first high-speed four-stroke single-cylinder power unit, Gottlieb Daimler. It is with his light hand all cars of the company, from the first day to the present, are aggregated with motors manufactured by Mercedes.
The car is an essential attribute of modern society. However, the appearance of the first cars was preceded by the invention of engines internal combustion(ICE), the history of which dates back to the distant 18th century. At the origins creation of ICE stood Gottlieb Daimler (Daimler-Motoren-Gesellschaft) and Karl Benz(Benz & Cie. Rheinische Gasmotorenfabrik in Mannheim).
Initially, both inventors were competitors, but due to the post-war crisis that hit all of Germany, they were forced to unite. The automobile company they created (1926) for some time bore the name of its owners (Daimler-Benz), but subsequently changed its name to Mercedes-Benz (Mercedes is the name of the daughter of one of the first customers of Daimler-Motoren-Gesellschaft).
As a result of its development, the company, over more than 100 years of its existence, has become a transnational concern Daimler A.G., which is currently one of the leaders in the global automotive industry. In many ways, this was facilitated by the fact that the company, starting from the first days of its existence, developed and manufactured internal combustion engines for its cars.
Daimler A.G. engines
Mercedes engines that are produced concern Daimler A.G., amaze with their diversity. Among them you can find motors:
- with inline or V-arrangement cylinders;
- with the number of cylinders from 4 to 12;
- atmospheric versions;
- supercharged (compressor, turbine or twin-turbo);
- sports versions of increased power.
All Mercedes power units (both gasoline and powered by diesel fuel) are very different. high reliability and operational durability.
Diesel engines
Mercedes diesel engines deserve a special mention. Mercedes-Benz company installed the first diesel engine in the world a car. It happened in 1935 when Taxi Mercedes 260 in the back of the W170 was aggregated diesel engine first generation OM 636 (power 43 horsepower).
Since then, a diesel engine in a passenger car will not surprise anyone. At the same time, Mercedes diesel engines, the design of which has been brought to perfection, have no equal in terms of power and efficiency. These motors are constantly being improved. For example, in 1997, the OM 611 4-cylinder diesel engine appeared with direct injection fuel common rail, which received the designation CDI.
Then 5 (OM 612) and 6 (OM 613) cylinder power units were developed, various modifications of which develop power from 156 to 231 hp. With. The year 2008 was marked by the appearance of a new generation of Mercedes diesel engines, labeled OM 651. The power units of this series have almost completely replaced the engines of previous generations.
Gasoline engines
Mercedes has been producing gasoline engines since its inception. Used in their manufacture a large number of technical innovations, which are designed to increase the performance of engines and reduce the amount of toxic substances in exhaust gases.
In addition, when developing new models, much attention is paid to reducing fuel consumption. The specialists of the concern approach the introduction of new products very carefully. So, working on the introduction of pressurization systems, the developers opted for a compressor, with which you can make a smooth increase in power without the unpleasant effects inherent in turbines.
The first engine mechanical compressor appeared in 1995. It received the designation M 111. Seven years later, a more modern power unit M 271 with power from 122 to 192 hp. With. (cylinder displacement 1.8 l), equipped with a multi-point fuel injection system. This engine was manufactured from 2003 to 2005. You can recognize it by the CGI marking. The same engine was produced with a turbocharger, developing power up to 204 hp. With.
Starting from 2004, a V-shaped 6-cylinder M 272 power unit with multi-point fuel injection was put into production. intake manifold. There are versions with direct injection. It was first installed in Mercedes-CLS vehicles, and then in E-Class models in the back of W212. In 2010, more than modern motor M 276, however, the M 272 engine is produced by Daimler A. G. today.

Description
The power unit M 272 is a V-shaped 6 cylinder engine with 4 valves per cylinder and multipoint or direct fuel injection. The model was developed to replace the obsolete M 112 E28 engine, which has been produced since 1998.
Structurally, the V-shaped cylinder block (camber angle 90 degrees) and its two heads are made of aluminum. Cylinder liners are made of silumin. The gas distribution mechanism (GRM) is driven by a double roller chain, the service life of which is 150 thousand km.
Characteristics:
- use of a DOHC type gas distribution system (two camshafts in each cylinder head);
- instantaneous change in the valve timing of intake and exhaust valves;
- dampers are installed in the intake manifold, which allows you to quickly change its length;
- the presence of a balancing shaft installed in the collapse of the cylinder block, which eliminates engine vibrations.
In total, more than 10 modifications of this engine were developed (M272.940 - M272.952). They were installed on Mercedes-Benz cars with indices 280 and 300.
Maintenance
Maintenance of the power unit M 272 E30 is reduced to regular and timely replacement engine oil (every 10,000 km) and coolant. It is also recommended to periodically inspect the engine for leaks and promptly eliminate them.
All engines of the M 272 family are critical to fuel quality. Fuel use Low quality leads to catalytic failure.
The roller chain of the timing drive is replaced after 150,000 km of run. At the same time, the chain tensioner and dampers are also changed.
Faults
The M 272 E30 engine is simple and reliable in operation. Subject to all manufacturer's requirements, big trouble will not deliver to the owner of the car. However, he also has typical malfunctions, the main of which are given in the table.
| MALFUNCTION | CAUSE | SOLUTION |
|---|---|---|
| Lit control lamp check engine(errors 1200 and 1208). | 1. Wear of balancer shaft sprockets. | Worn parts must be replaced. |
| 2. Stretched timing chain. | ||
| Engine oil leak. | Worn plastic plugs in cylinder heads. As a rule, a malfunction appears after 50,000 km of run. | Plugs need to be replaced. |
| Motor "troit". | Intake manifold flaps failed. The malfunction manifests itself after a run of 100,000 km. | The intake manifold assembly needs to be completely replaced. |
tuning
You can increase the power of the M 272 E30 engine in various ways:
- Purchase and install on standard piston group compressor. To do this, you need a kit kit from Kleemann / Lotec and others. This will increase the engine power to 380 hp. With. The disadvantage of this solution is the very high cost.
- There are also cheaper ways:
- remove catalytic converters and replace regular firmware for sports (chip tuning). This will increase the power of the power unit by 15 ... 20 liters. With.;
- replace regular camshafts for sports (phase 268/268, rise 11/11), which will also add power to the motor (about 25 horsepower).
If such an article had been written twenty or thirty years ago, its message would have been unambiguous - power Mercedes units perhaps not the most innovative, but among the competitors' motors there are hardly any more durable ones.
Today, Mercedes engines use a large number of technical innovations designed to reduce the number of harmful emissions and increase productivity while reducing fuel consumption. Unfortunately, this took a toll on legendary durability. And if nothing terrible is still happening to the engine block and head, then malfunctions of the injection system or supercharger have become something commonplace. Troubleshooting is usually expensive. It is gratifying that the company quickly learns from its mistakes and quickly overcomes them.
Petrol engines 1.6, 1.8, 2.0 M 111 / M 271

Compressor or turbocharger.
Mercedes has been rather cautious about supercharging gasoline engines. The Germans relied on a compressor instead of a turbine in order to provide a smoother increase in power without the unpleasant effect of "turbo lag". The result was presented in 1995 in the face of the M 111 motor with a mechanical compressor driven by a conventional ribbed belt. Seven years later it was shown over modern version- M 271.
The most widespread is the 1.8-liter version of the M 271 with a multi-point injection system with various degrees of forcing: from 122 to 192 hp. In some models, a modification with direct fuel injection was used. It was produced between 2003 and 2005 and developed 170 hp. It can be recognized by the CGI markings.
The desire to reduce capacity led to the creation in 2008 of the 1.6-liter M 271 with a compressor. Its use was limited to the C-class W204 and the not very successful CLC. The engine did not have direct injection.
The latest version of the 1.8-liter M 271 with direct injection received a turbocharger instead of a compressor. This motor developed from 156 to 204 hp.
Compressor wear.
For a long time, no one undertook to restore the compressor, offering only to change it. Fortunately, today mechanics have mastered the technology of its regeneration. The cost of such a service is about 100-120 dollars, including dismantling and installation. The most common compressor failure is rotor bearing wear as well as clutch failure.
If an annoying howl is emitted while the engine is running, then it's time to intervene. But be careful: exactly the same sound is made by worn generator bearings. You can buy a used compressor from a scrapyard for about $300, repairing a clutch costs about $500, and absolutely new unit will cost $1,500. Unfortunately, the compressor life is short - just over 100,000 km.
Timing chain jump.
Timing chain wear, unfortunately, is asymptomatic. She can jump over already after 60-80 thousand km. It is a pity that a weak single-row chain is used to drive the timing. Fortunately, its replacement is not too expensive - about $ 250. The fault applies only to M 271 motors.
Oil leakage from the valve timing regulator.
A typical malfunction of the older generation of M 111 engines. Oil begins to drain from the electromagnets, damaging electrical harness. Effective Elimination defect is a time-consuming task and, worst of all, not always feasible.
The use of engines 1.6-1.8 K / T (M 111, M 271)
These motors were used only in cars brand Mercedes. They were always located longitudinally in front. All units were assembled at only one plant in Germany.

Conclusion
If you decide on a Mercedes with a compressor, then be sure to choose a newer version of the M 271 and be prepared to invest in replacing the timing chain from the very beginning. The advantages of the 1.8 K engine are low fuel consumption. It is better to stay away from older versions of the M 111. Alternatively, you can opt for the naturally aspirated 2.0 16V or later 2.4 V6.
Gas engine V6 2.5-3.5 M 272
Short description.
V-shaped 6-cylinder;
24-valve;
Multi-point injection / direct;
For middle class cars and above, SUVs.
An aluminum V-6 with the code designation M 272 debuted in 2004. She became the successor to the M 112 V6, which has been used since 1998. The main changes are the use of the DOHC system (two camshafts in the head) and 4 valves per cylinder instead of 3. The design uses a number of modern solutions: instant change in valve timing of intake and exhaust valves, intake manifold variable length(i.e. dampers are present). In addition, a balancing shaft is used, which eliminates vibrations caused by a large camber angle of the block. As a rule, in V-shaped motors an angle of 60 degrees is used (i.e. a full shaft revolution divided by the number of cylinders), and in the M 272 engine it is 90 degrees.
Most units of the M 272 family have multipoint injection into the intake manifold. In 2006, a version with direct fuel injection debuted. Initially, the engine new system injection got Mercedes-CLS, and is currently used in the E-Class W212 with the designation CGI. In 2010, the successor to the M 276 was introduced, however, the M 272 series motors are still being produced today.
Operation and typical faults
The M 272 engine has only one characteristic malfunction. But its elimination is expensive, and the consequences are quite serious. Therefore, it is quite difficult to recommend the V-shaped six Mercedes.
Worn balance shaft teeth.
The defect has become so widespread that in the United States, owners faulty cars filed a lawsuit against a US company claiming free repair broken engines M 272. Wear of the gear teeth of the balancing shaft accelerates the wear of the chain and can cause it to jump. In addition, as a result of improper operation of the gas distribution system, dangerous composition mixture in the cylinders, which leads to the destruction of the catalyst. The fault affects all engines with serial number up to 2729…30 468993 inclusive. Repair parts are not too expensive (about $250), but the procedure requires the removal of the engine, which will cost about $700-1000.

Diesel engine 200-220 CDI-OM 611
Short description.
4-cylinder;
16-valve;
Common rail injection system;
Turbocharger;
For middle class cars and above, vans.
In 1997, a major change took place in the history of Mercedes diesel engines: for the first time, a Common Rail type direct injection engine was used. It was used in the first generation mercedes c-class with a station wagon. At the same time, the designation CDI appeared, which is still used today.
The engine was marked OM 611. It has 4 cylinders and a working volume of 2.2 liters. The first samples developed 125 hp. and 300 Nm of torque. Compared to its predecessor OM 604, the new unit received an increase in power by 30%, torque - by 100%, and fuel consumption fell by 10%. The injection system operates at maximum pressure 1350 bar. Initially, the engines were equipped with a turbocharger with a constant geometry, and since 1999 a supercharger with adjustable position turbine blades. The working volume was also slightly reduced from 2151 to 2148 cm3. The gas distribution system is driven by a chain, there are two shafts in the head, there are four valves for each cylinder.
The OM 611 engine family has several different modifications. In passenger cars (C and E-Class), a unit labeled 200 CDI (102-115 hp) and 220 CDI (124-143 hp) was used. In addition, there are variations with 82 and 102 hp. for Vito, Viano and Sprinter vans, 122 hp - for Vito and Viano, and 129 hp for Sprinter.
In 2002, with the debut of the E-Class W211 series, the new generation 4-cylinder engine OM 646 and its derivatives, the 2.7-liter OM 647 and 3.2-liter OM 648, were introduced. Despite the similar design, about 80% of the components new.
270/320 CDI (OM 612 /OM 613)
The next direction in the development of the OM 611 engine family was an increase in the number of cylinders. The 5-cylinder unit was designated OM 612, and the 6-cylinder unit was designated OM 613. The first, marked 270 CDI, developed from 156 to 170 hp, and the second, 320 CDI 197 hp. Mention should also be made of the 3.0-liter version of the 612 OM with 231 hp, designed for the C 30 CDI AMG.
Operation and typical faults
Mercedes diesel engines of the previous generation were famous for their incredible endurance. Due to the more complex design, sometimes there were problems with the OM 611. Just a larger number of elements had more chances to break. Fortunately, serious malfunctions didn't happen very often. The cylinder-piston group has high strength. The turbine and dual-mass flywheel typically last several hundred thousand kilometers. It should be borne in mind that the mileage of the car in the ads for sale coincides with the real one only in exceptional cases. When choosing a car with CDI, you must be guided by an assessment technical condition specific instance.
Difficult start.
Usually associated with pump wear. high pressure, less often with a malfunction of the injection system - injectors.
Intake manifold.
In many versions of the engine, dampers were installed in the intake system, the closing of which led to an increase in the turbulence of the air entering the cylinders, which improved the quality of its mixing with fuel. Malfunctions of this element lead to a noticeable decrease in engine power and a slow increase in speed.
Thermostat.
CDI engines warm up rather slowly. But if even after several tens of kilometers the motor does not reach the desired temperature, then the thermostat will have to be replaced.
Application of OM 611
4-cylinder engines were used in class C and E cars, and in minibuses. 5 and 6 cylinders in larger models.
Mercedes C-class W202: 09.1997-05.2000;
Mercedes C-class W203: 05.2000-02.2007;
Mercedes E-class W210: 06.1998-03.2002;
Mercedes V-class: 03.1999-07.2003;
Mercedes Sprinter: 04.2000-05.2006.
Conclusion
Very good engine for its time - an inexpensive injection system and a durable cylinder-piston group.
In the case of the E-class, instead of version 220 CDI, you can consider a model with 270 CDI.
Diesel engine 200-250 CDI-OM 651
Short description.
4-cylinder;
16-valve;
common rail;
Turbo or biturbo boost.
In 2008, Mercedes introduced a new generation of turbodiesel with the designation OM 651. Initially, the unit had a working volume of 2.2 liters, and since 2011, a 1.8-liter unit has replenished the family. Both diesel engines have the same cylinder diameter, but the smaller one received a shorter piston stroke - 83 mm instead of 99 mm. The compression ratio in both versions is 16.2:1.
The engine debuted in its best form- 204 hp It was installed on C class cars 250 CDI. The power unit had twin turbocharging and Delphi piezoelectric injectors. The same solution (biturbo and piezoelectric injectors) was applied a little later in a weaker 170-horsepower version of the 220 CDI. And if there were no special problems with supercharging, then the nozzles caused a lot of suffering. They were so serious that in 2011 the 220 CDI was modified, and since 2012 the 250 CDI received conventional electromagnetic nozzles.
Weaker versions (up to 200 CDI 143 hp) used less troublesome solenoid injectors from the start. In addition, these engines had a single variable geometry turbocharger.
The OM 651 has replaced a wide range of older generation 4, 5 and 6-cylinder longitudinal and transverse engines ranging from compacts to vans.
Operation and typical faults
A shadow on the reputation of OM 651 was cast by problems with piezo injectors. The scale of the defect was enormous. To eliminate defects during warranty period, had to stop the current production of engines. It must be admitted that Mercedes conscientiously approached the issue of eliminating the problem. Motors with conventional injectors did not create such problems.
Piezoelectric nozzles.
This standard fault first years of production. The engine switched to emergency mode. There were cases sudden stop motor. At present, the scale of the problem is small.
Valve train chain.
With increasing mileage, more and more facts are being recorded about problems with the timing chain. The replacement is troublesome - the chain is located at the rear of the engine.
Pump leak.
Another problem that is gaining momentum with increasing mileage and the age of cars.
Application of OM 651
The OM 651 engine has found wide application, ranging from compact models to limousines, sports cars and even vans.

Epilogue
Legendary Mercedes engines in pursuit of power, low flow fuel and environmental friendliness have lost their former reliability. The block itself cylinder-piston group designed for at least 500,000 km, but auxiliary equipment fails much earlier, and repairs are very expensive.
Mercedes cars are the epitome of quality and style, because German manufacturer produces reliable cars that are adapted to any road. The Mercedes contract engine is designed for high mileage and is great for replacing the “native” engine.
A little about contract motors
Boo motor mercedes benz - this is a line of 4, 5, 6-cylinder units. They are in-line or V-shaped. For the most powerful cars units of the V8 and V12 series were produced. There are supercharged motors equipped with twin turbo, compressor and turbine. sports cars AMG series are equipped with V8 / V12 engines. Apart from power motors diesel production continues. Such engines come in various configurations, power and volume.
You can buy a Mercedes contract engine at Auto Parts. Enough to pick up suitable model and place an order.
Typical Mercedes engine failures
The need to replace a used engine for a Mercedes arises as a result of the manifestation of the most common breakdowns:
- unusual motor noise during operation indicates normal wear and tear compressor. The same sound indicates a broken generator bearing;
- stretching or jumping the timing chain - such a breakdown is asymptomatic. Occurs when high mileage at 60–80 thousand km;
- a leak engine oils. As a result of runoff motor fluid damage to the harness occurs from electromagnets;
- balance shaft failure. Its teeth wear out over time, reducing the period of use of the motor. A possible violation of gas distribution provokes the formation of a dangerous mixture, leading to the destruction of the catalyst;
- startup difficulties. The internal combustion engine may refuse to start due to damaged injectors and a worn out high pressure pump, in which case it is worth considering replacing with a used Mercedes-Benz engine;
- interruptions in the operation of the exhaust manifold lead to a decrease in power;
- thermostat malfunctions cause the unit to stop heating up even after a long operation.
The occurrence of one of these problems leads to the fact that the motor needs to be changed. The price of a used Mercedes engine depends on specific model and its power.

Mercedes cars in the back of the W124 were produced in Germany from 1984 to 1996. At the time of its debut at the Seville Motor Show, the W124 was presented to the general public with seven types various engines. These models are: 200, 230E, 260E, 300E, 200D, 250D, 300D. The presence of the letter "E" after the numbers in the model name petrol car at that time it meant that the engine was injection. In 1993, the entire Mercedes family in this body became known as the E-class and the letter moved to the beginning of the model name. Engines with a carburetor were no longer produced, and there was no longer any need to indicate the difference with additions to the name. At diesel options the model has lost the "D" marking. It was replaced by an addition in the form of DIESEL, or TURBODIESEL.
In 1987, the 300D TURBO was added to the engine lineup, and a year later, the 200E and 250D TURBO.
In 1989, the entire series of diesel engines was modified to meet the requirements of the Diesel-89 program. The prechambers were updated in the engine design, and a new fuel pump. As a result, exhaust smoke has decreased by 40%.
In 1990, a 3.2 liter became available in all body styles of the model. Gas engine M104. In the same year, the 500E model was released with a 5-liter engine and 326 hp. (top)
In 1992, the range of gasoline engines was greatly updated. 4 valves per cylinder appeared in the design, while a new one was installed instead of structurally old injectors electronic system fuel injection. Ultimately, everyone gasoline units increased power, increased torque, decreased harmful exhaust. Then it became available a new version 400E, equipped with 4.2 liter engine(transmission, of course, automatic). At the end of 1992, they began to update and diesel engines. Engines with five and six cylinders received 4 valves per cylinder. Four-cylinder engines and turbocharged diesels still had two. The update improved the performance of the engine and its torque, reduced fuel consumption and exhaust emissions. motor u diesel versions, as with gasoline ones, it began to be equipped with a regular catalyst.
Let's take a closer look at each engine model used on the W124 family.
Petrol
M102.
It appeared in 1980 and was produced until 1993, until it was replaced by the M111. It was a four-cylinder petrol engine.
Produced in both carburetor and injection versions.

M102 and M103 engines are very reliable and normal conditions operation, with correct and timely maintenance quietly pass 500 or more thousand kilometers.
Sores: among the problems, one can single out frequent blockage in the nozzles and, as a result, instability in the operation of the engine. Injectors should be checked regularly and replaced if necessary. In such motors, crankshaft oil seals and front cover gaskets often leak. Oil scraper caps are best changed every 100 thousand km. mileage, otherwise oil consumption will increase. These motors have weak chain Timing and drive sprockets. As a rule, they wear out for 100-150 thousand km. and they need to be repaired.
M104.
Six-cylinder petrol injection engine. Used for W124 in various upgrades from 1990 to 1996.

Perhaps one of the most successful engines of that time. Among the shortcomings, frequent oil leaks due to wear of the cylinder head gasket can be noted - it is treated by replacement. With high mileage, there may be a loss of power. The problem is solved by replacing the air meter, which starts to work poorly after 100 thousand mileage. M111 engines are quite noisy. Often you have to change the spark plugs. The pump has to be changed every 100 thousand.
M119.

The history of the concern begins with the history of two independent companies that opened the era of the global automotive industry. In 1883 Karl Benz founded Benz& Co, the result of which was the world's first mass-produced passenger car, which appeared on the market in 1894. In 1890, Gottlieb Daimler founded the "Daimler-Motoren-Gesellschaft" company, in whose workshops in 1901 the first car appeared under the name "Mercedes" (named after the daughter of one of the co-owners of the company). In 1926, the competing companies merged to form "Daimler-Benz AG", and the car model they produced was named "Mercedes-Benz".
The brand's logo is a three-beam star, symbolizing the three elements - air, water and earth. In addition to the production of cars, trucks and special vehicles The company produced high-power engines for motor cars, boats, ships and aircraft. The name of the concern "Daimler-Benz" was created by outstanding engineers Ferdinand Porsche, Fritz Nallinger and Hans Niebel. By the 1930s, the company had established itself as a designer and manufacturer of luxury cars.
All Mercedes Models:
The history of Mercedes - Benz has many cars that have become iconic: the world's first mass-produced passenger car with diesel engine Mercedes - Benz 260D, elite "770 Grosser", Mercedes W126, generation of class S, indestructible W190, W123, W124, classes C and E, which set new standards of quality and reliability, the famous super-luxury 300s and 600s. Models are produced with reliable and high-tech engines of various modifications, high-quality suspension, reference design interior, body high degree passive safety, new security systems EPS, ASD, 4MATIC. In 1998, Daimler-Benz AG and Chrysler Corporation merged. As a result, the most gigantic automotive corporation in the world, Daimler Chrysler AG, turned out. Having initially relied on elitism and prestige, Mercedes was nevertheless able to become a truly popular brand. When releasing a luxury car, the manufacturer did not forget ordinary consumers: model range there have always been more affordable models. And in any configuration, Mercedes remained a super-reliable (until recently;), prestigious, comfortable and convenient car.
