Motor family N55 is newest development BMW specialists, which came to shift the Motors of the N52 and M42 series. These BMW engines are distinguished by reliability and more than once received a prestigious reward motor year.

This engine modification is designed for use with powerful sports sedans and provides cars with excellent dynamics and excellent fuel efficiency.

Motor bMW series N55 is designed from a six-cylinder unit that used the BMW M52 engine. The motor received additional turbocharger, which made it possible to significantly increase its power.
We also note that improved, in comparison with MO 42 engines, ecology indicators, which managed to be done by using the gas recirculation system.
BMW company successfully implements a strategy for reducing its power units, which allows the power without loss of power to reduce the car mass and improve fuel efficiency indicators.
Today everything gasoline engines BMW, installed on older BMW models, use turbocharger. Motor N55, as well as the first modifications of M10 motors, received a compact turbine, which made it possible to significantly raise the power of the motor. This force aggregate Differs in increased requirements for service. BMW oil and all used technical fluids Must comply with the manufacturer's recommendations.

Description

This modification of the engines combines excellent dynamic characteristics, is distinguished by reliability, which consistently affects the popularity of the power unit.

According to statistics, the model BMW 535, which is set to N55, accounts for about a third of the fifth generation sales.

This motor received the latest Bavarian development - Twin-scroll supercharger, which is a turbine with two snails with a different diameter that actively uses exhaust gases. German engineers managed to completely eliminate turboyami effect, so the BMW engine appears from the lowest revolutions.

This power unit, as well as the M42 motor model, is completed various species Transmissions. It can be both a six-speed mechanics and a number of automatic boxes. The greatest popularity together with the BMW N55 engine received eight-adjusted automatic boxeswhich differ in smoothness of work and provide a car excellent dynamics.

BMW engines are made of fully aluminum alloy, which ensures the ease of the force aggregate. In this case, the BMW engine is not afraid of overheating and can operate in extreme temperature conditions.

Aluminum began to be used on the M20 series engines, and the BMW M40 engine was the first completely aluminum sea. Another significant advantage of using such metal alloys in BMW engines is their ease, which made it possible to reduce the mass of the engine by 40 kilograms compared to the M42 motor.

We also note the use of ValveTronic system on the N55, which changes the height of the valve lifting, which in turn allows you to optimally control the operation of the power unit.

For the first time this system was applied to the M40 series. On the low revolutions inlet valves rise to minimum heightThat ensures optimizing the operation of the BMW engine and reduces fuel consumption. But it is worth the driver to press the gas pedal as the Valvetronic system increases the move inlet valvesthat will allow you to raise the torque and improves the dynamics of the car. This system is lubricated by BMW oil under high pressure and requires relevant service.

In 2012, an upgraded version of this BMW engine was developed, which received the N55HP index. New BMW engines obtained a modified output collector and other small changes that allowed to increase power up to 315 horse power.

Moreover, the maximum torque is achieved with 1,300 revolutions per minute. Similar indicators of traction on the nides are characteristic of diesel engines and power units of the M10 series, and the BMW N55HP engine itself provides excellent dynamic indicators. New Motor got a modified lubrication system in which BMW oil moves with increased pressure in system.

Tuning

When making motors of the M50 and N55 series, German engineers used the latest technological advances, which allowed them to design and make a powerful power unit, which gives more than one hundred horsepower from one liter volume.

This is a truly grandmaster line, which is characterized only for the most powerful and high-tech engines.

If we talk about the possibility of tuning this engine, it should be noted that the possibilities for increasing the capacity are significantly limited. You can explain the like that already initially in front of the engineers was tasked to make the most powerful engines BMW. And that is why any work on increasing the power of the M52 and N55 motor can lead to a decrease in the reliability of the force aggregate.

Only replacement is possible exhaust system In M50 and N55, which allows you to add about a dozen horsepower.

We can recommend setting the exhaust from M52 and M5, which gives a motor with a volume of three liters with great sound and increases its power. Installing a new exhaust from M5 or from model 550 forces the replacement of bumper with exhaust pipes.
Installing a new engine control unit allows you to reconfigure the modes of the power unit, adding it about 30 horsepower. This tuning is characterized by simplicity and has an affordable cost. At the same time, it must be said that such a chip tuning significantly reduces the motor resource, especially the turbine, which can break under the increased load. As a result, every 100-120 thousand kilometers requires expensive overhaul.
Extreme tuning programs for increasing the power of the N55 motor power involve the installation of a new turbine from Motors M 42, which ensures the maximum possible pressure. Such works allow you to get about 100-150 additional horsepower. According to the dynamics, such a formated N55 will be approached by the older eight-cylinder model with a volume of 4.4 liters. However, the indicators of reliability and resource of the forced engine are significantly reduced.

M10 engine

Volume 1.5, 1.8, 2.0 liters
M10 is a 4-cylinder 8-valve small-litter engine. It apparently should be recognized as a long-lived record for the BMW engines. An incredibly successful constructive was designed for 114 body in early 60s. With the "original" execution of M10, the Russian car enthusiast can easily familiarize himself with the Muscovite-412 or 2140 under the hood (it was M10 AZLK copied when developing a "its" engine). Such a longevity on the one hand talks about a wonderful design, on the other, it makes it clear that in the late BMW models, this engine looks too obsolete.

Before this engine appeared in the "New Class" sedans 1500, the post-war BMW engines were represented by a pre-warning upgraded 2 liter row six, excellent, but very expensive aluminum V8 and several adapted motorcycle engines. The history of M10 engines originates in 1958, when the engineer Alex Falkenhausen proposed 1 liter four cylinder enginewhich was proposed to be installed on the 700 model. This engine did not get into production, but the basic concepts of his design found the use of a "new class" engine. It was a design with a cast-iron cylinder block, aluminum head and a chain drive of one camshaft. It was created with a margin that allowed to subsequently bring a working volume to 2 liters and gave many variations of this motor during almost a quarter of a century. On the 2 liter version in 1973, the turbine was also installed - these engines were used in the 2002 Turbo models.

The M10's "new" history was established on E12 (models 518, 520i), E21 (315, 316, 318, 318i, 320i), E28 (518) and E30 (315, 316, 318i).

M20 engine 2.0, 2.3, 2.5, 2.7 liters

The M20 is a 6-cylinder 12-valve engine comparatively small (for BMW) volume and camshaft belt - was developed and began to be produced on BMW back in 1977 under the M60 labeling.

Mostly the engine was intended for the new and first car of the 5th series in the 77th year - E12. To create modern, economical and not expensive versions of cars. In addition, for the 3rd series cars, a more powerful engine was also required, under the hood of the Trex BMW, it was simply enough enough space for engines M30 (M89).

The new engine was different from his senior M30 fellow easier design and camshaft belt drive. Nevertheless, the engine retained the cast iron block of cylinders with an aluminum head. An important innovation in M60 was the appearance of a camshaft belt drive, instead of the chain used earlier.

In the 82nd year, the M60 engine was slightly upgraded and it received the M20 marking. Also, the M20 began to call the previous issues, and the name M60 was assigned in 93 to a completely different engine. The troubles between M20 and M60 were very insignificant.

On M20 there is no fuel pump in the cylinder block, and the number of teeth on the belt of gas distribution - M60 - 111, M20 - 128 has changed, and from the 85th year - 127. Accordingly, the gears of the timing mechanism changed, as well as the belt tensioner roller.

The further development of the M20 brought 2.5 liter 170 strong version and the deformed 2.7-liter modification.

The feature of the M20B27 engine of 2.7 liters was that the engine was strongly defined. He issued only 125 hp At 4800 rpm, but it had a very high torque of 241 HM at 3250 r. For which he received the nickname "petrol diesel".

The models equipped with such a motor had the designation 325E, 525e, and on the US market 328E and 528e, respectively.

The M20 engine was installed on the cars of the third and fifth series.

Third Series:

E21 - 320 - 2 liters, only carburetor, 323, 323i - 2.3 liter carburetor or mechanical injection K-jetronic.
. E30 - 320i, 323i - 2.0, 2.3 liters - with K-JECTRINIC injection system or L (E) -Jetronic, 325i, 325E - 2.5, 2.7 liters with Motronic 1.0 Basic injection system.

Fifth Series:

E12 - 520 - 2.0 liters - only carburetor.
. E28 - 520i - K or L (E) -JECTRONIC, 525E - 2.7 liters with Motronic 1.0 Basic injection system
. E34 - 520i, 525i - 2.5, 2.5 liters with injection system Motronic 1.0

BMW M20 engine block head.

The M20 uses several types of GBC, however, the differences between them were very insignificant. The M60 carburetor engines and the K-Jetronic M20 were installed heads with reduced intake channels, more precisely, when the L-Jetronic injection system appears, the inlet channels were significantly expanders.

The smaller cross-channel cross-section was required for more correct mixing (features of the carburetor), as well as for better filling cylinders on small revolutions.

For the M20 B25 engine, the block head was also substantially changed. Namely installed valves of increased size - intake 42, exhaust - 36. Instead of 40 and 34 for other modifications.

Nevertheless, the heads are partially interchangeable, although, sometimes, and with some alterations.

For example, B20 and B23 are completely interchangeable, B25 C B27 C 9/87 are completely interchangeable, and with some alterations B20 / B23 and B27 (up to 12/86), and, of course, carburetor interchangeable with injection.

B27 head one of the most interesting from the heads used.

Depending on the years of release, they were both with thin intake channels (both on the M60 carburetor motor and on the K-Jetronic M20) and the combustion chamber of a similar B20 and with large, almost rectangular intake channels, an increased combustion chamber and camshaft from the 7th necks (if you replace the camshaft then a full copy of B25). But there were also intermediate versions - increased inlets of oval shape, an increased combustion chamber and camshaft with 4 cervices.

Engine M21 2.5 liters (diesel) 82-91 g. (E28, E30)

M21 - 6-cylinder diesel engine - became the first diesel engine in the history of the company BMW. Production has begun in 1982 to equip the 524TD model in the new bodies that appeared E28. M21 was equipped with turbocharged, which allowed and in a diesel version to keep the image of a dynamic machine inherent in all models BMW.. With the release of the new body of the 3rd series E30, the M21 appeared another application - model 324TD.

In 1985, an attempt was made to produce an economical version without turbocharging. But a leisurely 524D and 324d did not fall to taste to buyers. Already the next year, the release of undead diesel engines was stopped and never renewed.

Engine M30 volume 2.5, 2.8, 3.0, 3.2, 3.5 liters

BMW Concern Darling Bernard Oswald from ford. To develop a second generation of six-cylinder engines in the middle of the sixties. The first were six-cylinder engines with seven crankshaft supports. They were used in the new sedans of the E3 series in 1968. A successful formula M10 was re-applied - a cast-iron unit, an aluminum head with a chain camshaft chain drive. After 1972, the razorbank was under the control of Gustav Edrier and then the first model with 4 valves appeared - M88

Engine M30 - large 6-cylinder engine with inline cylinder arrangement, which has modifications 2.5, 2.8, 3.0, 3.2 and 3.5 liters of working volume. It can be found on the 5th series (E12, E28 and E34), the 6th series (E24) and the 7th series (E23 and E32), as well as the famous BMW M1.

The engine turned out to be very successful, both in design and vitality. Of course, in part, the vitality of the engine was provided with its high power. Due to the fact that more powerful engines and load less.

Only modification M30B35 was unsuccessful with a cylinder diameter of 93.4 mm - it turned out to be too powerless. But do not confuse it with the M30B34, which was installed almost all 3.5 liter machines.

M30 is an engine for a quiet ride, it has too heavy piston and too much piston strokes that do not allow him to quickly promote and create large loads on bearings (inserts).

Also, due to the high mass of the piston system, the engine is very demanding of the oil, if it is fed to mineral oil, and at the same time keep it in the range of revolutions of 4-6 thousand, after several thousand it will have to grind the crankshaft. In this engine you need to fill only synthetic oil And if you like to twist it, then on volumes of more than 2.8 liters - necessarily requires the installation of an oil radiator.

On the other hand, the advantages of the balance of the row six and high power on low revs with more than compensate for these shortcomings.

Also M30 - was the second and latest Engine To which turbocharging was serially installed - the turbocharged M30 modifications were used only in the 745i models in the body E23. In fact, their volume was 3.2 and 3.4 liters, depending on the modification. But both options were labeled M102. Power is the same - 252 hp The main difference is the ignition and nutrition system.

The engine was installed on cars of the third, fifth, sixth and seventh series.

3rd series:

E30 - 333i - 3.2. Litra, with Motronic injection system. Supplied only in the UAE.

5th series:

E12 - 525 - 2.5 liters with a carburetor, 528 - 2.8 liters. With a carburetor and an injector, 535i - 3.5 liters, only with an injector.
. E28 - models 525i, 528i, and from 85 years 535i and M535i. Starting from the E28 body, only injection modifications were installed.
. E34 - 530i - 3 l., 535i - 3.5 liters. Also, only the injector with the Motronic injection system and the crankshaft position sensor located on the crankshaft damper, and not on the checkpoint.

6th series:

E24 - 628CS with carburetor and injection (628CSI), 633CSI, 635CSI - only injector.

7th series:

E23 - 728 Injector / Carburetor, 730 Carburetor, 732i / 733i, 735i, 745i - A turbocharged version of the motor was installed on the 745i model.
. E32 - 730i, 735i - 3.0 and 3.5 liters, respectively.

BMW M30 engine block head.

The GBC engine BMW M30 is perhaps the most unified of all existing.

Cardinal differences have only carburetor and injection heads, and the difference is so strongly impossible to interpret them in principle.

The rest of the block is completely identical, right up to the gas distribution phases (camshafts).

Otherwise, in the design of the GBC there are no fundamental differences from other BMW motors. The movement of gases through the engine is transverse, the combustion chambers have a three-cell form, V shaped location of the valves with the top camshaft.

M88 24-valve modification M30 1979

On the basis of the M30 engine, a model with two camshafts and 4 valves per cylinder was developed. Initially, they were installed on the M1 supercars, later the same engine with the M88 / 3 encoding engine was installed on the M635CSI model, although later received marking S38 B35.

Engine M40, M42, M43, M44 1.6-1.8 liters since 1987 (E28, E30, E34, E36, E39, Z3)

1.8 liter M40 engine was designed in 1987 to change outdated M10 on the 3rd series (E30 body). He inherited the design of the cast-iron cylinder block already familiar to the M10, but hydrocompensators were already applied in the aluminum head, which, together with the change of chain camshaft camshaft on the belt, made the engine significantly quieter. However, in the next model M43 was again used chain drive camshafts as well as in four-flaped modifications of this engine M42 and M44.

Two years later (in 1989), a lightweight modification of M40 1.6 liters was released (on some sources this engine has a M43 code). M40 engines were widely used to equip junior Bodges E30, E36, Z3.

In Russia, currently sold BMW x5 with gasoline and diesel engines with supervision. Today we will talk about the technical characteristics of these motors. The x5 gasoline engines have a volume of 3 and 4.4 liters, this is a row 6-cylinder unit and more powerful V8. BMW X5 diesel engines have one volume of 3 liters, but all aggregates various power. There are three versions of diesel engines with a superior, double and even triple superposition. Diesel with a triple superior is the main technical novelty X5 third generation.

The blocks of cylinders of all power units are made of aluminum-magnesium alloy. The TRG drive traditionally uses the chain. In the N55B30 gasoline, a working volume of 3 liters is one turbine, from the performance of which depends the final power of the power unit. System of changing phases of gas distribution stands on two distributive shaftx (Bi-Vanos). There is a system for changing the lifting height of Valvetronic III and direct injection Fuel with turbocharger. Behind the supervision corresponds to the TwinScrolf Borg Warner B03. At a more powerful BMW X5 engine (Motor model N63B44) with a volume of 4.4 liters in the configuration V8 costs a double prediment. Further, the technical characteristics of the BMW X5 gasoline engines.

The electronic motor control system allows not only to determine the parameters of the power unit, but also change them. You can increase the power of the BMW engine using chip tuning. In St. Petersburg, this can be done in the Accession Tuning Studio. The process of changing the factory engine control program will increase power and improve dynamic indicators. We read about the standard characteristics of the fifth engines further.

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.

The content of the article:

The view is that the quality and productivity of the engine work depends on its volume, has long been in the past - modern trends in mechanical engineering are based on a decrease in the volume of the motor with simultaneous increase in its power.

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

BMW originates in 1913. In a small at that time, the German town of Munich united two small companies engaged in the production of engines for the aviation industry. A new enterprise was named Bayerische Flugzeugwerke (BFW).

In 1917, a logo was created, which in our time is a sign 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.

The name of BMW, under which the company is known to the modern consumer, appeared in 1920, after the production of any aircraft was prohibited from the Versailles of Germany. For a while, the factory BMW released the brakes for aircraft. But the crews of the company decided not to delay in the air industry - in 1923 the first was created motorcycle BMW..

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 car brand. BMW The company 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 in 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. First place is absolutely deserved diesel motorsBMW released:

The device was produced in two modifications: 3.9 and 4.4 liters. The cylinder block and the crankcase were made of cast iron, which significantly increased the weight of the engine, but at the same time put high strength to the motor.

The best among gasoline engines

Among motorists are very popular with cars with a gasoline engine. Such a demand is explained by simplicity in production and, as a result, a relatively low motor cost.

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

Gasoline engines are not considered too economical, but recently the installation and use of HBO, which operates perfectly in a pair with a gasoline engine internal combustion, solves this problem.

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

The innovative system of Vanos gas distribution can significantly increase the performance of the device, while the fuel consumption is significantly reduced.

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 a clear advantage of diesel - diesel fuel Cheaper than gasoline.

What kind of diesel engine from BMW international experts recognized the best?

16-valve N47., quite successfully replaced its predecessor - diesel M47. 4 cylinders, 2 camshafts, injection system, reaching pressure 2200 bar, aluminum crankcase - this is not all technical advantagesallowed to take the first places in the categories "Best New Developments" and " Best Engine volume from 1.8 to 2.0 liters. "

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 concern BMW. Granted fans of his auto the opportunity to "make the world cleaner."

BMW B58. - gasoline 6-cylinder turbocharged engineArgued by the remarks of car owners in early May 2015. For such a short period of existence, he managed to get several awards of the highest category in international competitions. Among the consumers it is called "Breakthrough in Motor Station" and nothing else.

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.

To minimize fuel consumption in B58 uses an innovative pump control card and a direct highway in the injection system. Under the concept of TwinPower Turbo it means using several technologies at once: Vanos, Valvetronic, TurboCharging and Direct Injection.

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 giving the right cars BMW To carry the proud title of leader of the world car industry.

BMW Engine Decoding

Decoding and designation of the engine BMW according to the engine model:

the family of engines is mainly indicated by the letter:
- M - Engine developed until 2001;
- N - Engine developed after 2001. Since the beginning of the 2000s, BMW revised its naming strategy, in order to simplify understanding and obtain more detailed information About updates in the motor. The innovation for N Series engines has become a new design, parts manufacturing material and technology used in the motor itself;
- B - modular motor. Since 2013, BMW has begun to introduce a new family of modular motors. The first cars that received new engines of the "B" series were hybrid sport car and the lineup Compact mini. Both of these cars were equipped with a 3-cylinder engine B38 with a turbocharger - direct injection - Valvetronic. The family of modular engines B Series includes gasoline and diesel power units that have interchangeable components and architecture (60% of parts are identical, for example, a 3-cylinder engine has components from 4 and 6-cylinder engines B series). The engine volume increases in increments of 500 cubic centimeters - 1.5L - I3, 2.0L - I4, 2.5L - I6, 3.0L - i6, etc.;
- S - Engine BMW Motorsport;
