Diesel BMW engines TwinPower Turbo
BMW Twin Power diesel engines embody the principles of BMW EfficientDynamics: a combination of outstanding fuel efficiency, increased power and excellent driving performance. Vehicles with diesel engines can serve as models of efficiency and dynamics. At the same time, the BMW TwinPower Turbo 3-cylinder diesel engines are ideal entry-level powertrains; The innovative 4-cylinder BMW TwinPower Turbo engines and the powerful 6-cylinder BMW TwinPower Turbo diesel engines do their job with exceptionally low emissions and frictional losses. Diesel units from the BMW EfficientDynamics family with a lightweight aluminum design are equipped with variable geometry turbochargers and CommonRail direct fuel injection latest generation.
From the base series to the M5 super sports car, the BMW brand has always defied automotive logic. Cars that seemed incredibly fast on paper exceeded all expectations when launched into the series and when we met in person. Many, if not all, BMW engines work like magic, but when the hood of another Bavarian masterpiece opens, there are no ancient Germanic runes under it, only the inscription “TwinPower Turbo” flaunts on the protection of the power unit.
BWM has always preached a policy of turbocharging and rear wheel drive. Today, you will not find a brand power unit that does not have at least one turbocharger, not to mention a series of high-performance diesel engines with three- and four-turbine units.
Twinpower plays important role when it comes to efficient and dynamic BMW petrol and diesel engines. But what is TwinPower Turbo in reality and what does it have to offer the automotive world?
When it comes to gasoline engines, TwinPower Turbo, there are three components that are used in all modifications, from 3 to 12 cylinders:
valvetronic;
direct fuel injection;
turbocharging
Turbodiesels are equipped with a common rail injection system.
Valvetronic– electronic variable valve. This is a technology developed by BMW that optimizes fuel consumption by adjusting valve lift. The developers claim that this technology alone can reduce fuel consumption by 10%.
Volvetronic- powerful electronic technology. It provides continuous and precise control of intake valve lift. This means that when the Bavarian owner presses the gas pedal, the valve opening control starts, instead of the usual throttle valve intake systems open.
The system uses a set of rockers controlled by an electronic camshaft. Since it is able to regulate the valves from fully open to almost closed, the engine does not need to rev to increase the load.
Valvetronic was first introduced in 2001 on the 316ti series and was used primarily for mass-market supercharged engines such as:
N42 straight-4;
N52 straight-6.
But the system was not used on the N54 twin-turbo. Instead, the turbocharged N55 straight-6 that replaced it in 2009 with the same performance as the top-end 7 Series N74 twin-turbo V12 was fitted with valvetronics. After that, the technology was applied to almost all BMW cars.
High Precision Injection– direct injection systems with central multi-toothed injectors. They gradually replaced the technologies used in the 2000s. Supercharged and turbocharged engines used piezo injectors. However, the new BMW N55 6-cylinder turbo engine, launched in 2010 and installed in the 335i, 535i, X3, X5 and X5 models, uses a solenoid injection system developed by Bosch. This system was chosen by the Bavarians to keep prices competitive in the North American car market.
The name TwinPower Turbo has confused many car owners. They did not understand what was under the hoods of their BMWs. In this regard, the company was sued for defrauding a large number of people. The document called the TwinPower Turbo a "false twin" and stated that the Bavarians launched an advertising campaign to deceive customers. It's all about the word "double", which is present in the title. Its presence was not a guarantee of equipping engines with two turbochargers.
The TwinPower Turbo initially appeared on a twin-span single turbo (installed on the 5 Series Gran Turismo in 2009, and in 2010 the E90 335i, 135i, X3 and X5 models appeared), starting with the N55 (turbocharged six-cylinder engine) and N74 (6-liter V12 unit with two turbochargers). It was equipped with the 2009 760i and 750Li models. Two-speed turbocharging is the core technology for BMW's TwinPower Turbo.
The twin-turbo design starts with an exhaust manifold separating the exhaust gases. They are carried through different spirals called "scrolls". The turbo has two nozzles of different diameters, they are needed to ensure a quick response of the power unit. BMW names special exhaust manifold own design Cylinder-Bank Comprehensive Manifold or CCM.
It should be recalled that modern engines BMW TwinPower is not necessarily equipped with two-stroke turbochargers. What they do have, however, is a great exhaust manifold that traps more exhaust gases for delivery to the turbos, delivering lag-free power.
Three-cylinder revolution: B37 and B38 TwinPower Turbo. Gasoline and diesel
BMW's next revolutionary solution is three-cylinder petrol and diesel engines that can compete with modifications with more cylinders. They are built in a modular system, using the same 500cm cylinders, paired with TwinPower Turbo technology producing 120-220 horsepower.
It is known that diesel units received the designation B37, and gasoline - B38. The first samples are installed on a hybrid sports car i8 series FWD 1 and MINI. They are also used by the RWD 1 and 3 series as starter modifications. model range engines.
The best 4-cylinder turbos in the world
In 2004, the production of a direct injection engine developed jointly with PSA Peugeot Citroen began. In 2011, BMW designers developed the N13 model, in which the body was changed oil filter- it was installed longitudinally. The engine was installed in the 114i, 116i and 118i models.
Perhaps a promising engine for BMW now is the N20. Its working volume is 2.0 liters, there is a four-cylinder turbocharger. The motor also has "TwinPower Turbo" written on the cover. This engine replaced the less powerful straight 6 sibling in the 20i, 28i, and is a viable and very efficient alternative.
There are 2 modifications of N20. The 184 PS version is less powerful and available for X1, xDrive20i, F30 320i, 520i, base Z4 sDrive20i. The top variant of this 2.0-liter TwinPower engine has a power of 245 hp, is used in the F30 328i, 528i, X1, X3 and Z4 models.
Straight-6 TwinPower Turbo: N55
When TwinPower Turbo technology is installed on a 6-cylinder engine, its benefits become clear. The twin-turbo N55 replaced the more expensive N54 in 2009. But both modifications are very similar to each other. Comparable output to BMW's own 4-litre V8, with a lighter block and lower torque, even more tan to be found in an E92 M3 with a powerful S65 V8.
The power of the N55 is 302 hp and the torque is 300 Nm (400 Nm). It is installed in models 335i, 135i and all SUV modifications. There is an even more powerful version under the N55HP index, with a power of 315 hp and a torque of 450 Nm. Top models such as the 640i, 740i, and even the sporty M140i super-heavy hatchback are equipped with this version.
The debut of the engine took place in 2009, it began to be installed on the fifth series of GT. Equipped with an advanced version of the 6-cylinder engine, the BMW 535i Gran Turismo can accelerate from 0 to 100 km/h in just 6.3 seconds. Max speed this beast is limited to 250 km/h. In terms of fuel consumption, the BMW 535i GT consumes 8.9 liters per 100 kilometers. The CO2 emission index is 209 g/km.

twinturbo and biturbo what is the difference and what are the differences
Contrary to the beliefs of some "experts", the name of the system biturbo or twinturbo do not display the turbine operation scheme - parallel or sequential (sequential).
For example, at Mitsubishi car 3000 VR-4 turbocharging system bears the name TwinTurbo (twinturbo). The car has a V6 engine and it has two turbines, each of which uses the energy of the exhaust gases from its three cylinders, but they blow into one common intake manifold. U, for example, German cars there are systems similar in working principle, but they are not called twinturbo (twinturbo), but BiTurbo (BiTurbo).
By car Toyota Supra two turbines are installed with the inline six, the turbocharging system is called TwinTurbo (twinturbo), but they work in a special sequence, turning on and off with the help of special bypass valves.
The Subaru B4 car also has two turbines, but they work sequentially: on low revs a small turbine blows, and at high, when it fails, the second turbine is connected bigger size.
Let's take a look at both systems now. bi-turbo (biturbo) and twinturbo (twinturbo), or rather, what they write about them in “these your Internets”:
bi-turbo (biturbo) - a turbocharging system, which consists of two turbines connected in series. In system biturbo two turbines are used, one small and the other larger. The small turbine spins faster, but high revs engine, a small turbine cannot cope with compressing the air and creating the necessary pressure. Then a large turbine is connected, adding a powerful charge of compressed air. Consequently, the delay (or turbolag) is minimized, and a smooth acceleration dynamics is formed. Systems biturbo not a very cheap pleasure and are usually installed on high-end cars.
System biturbo (bitrubo) can be installed as on a V6 engine, where each turbine will be installed on its own side, but with a common intake. Either on an in-line engine, where the turbine is installed by cylinders (for example, 2 for a small and 2 for a large turbine), or sequentially, when on exhaust manifold First, a large pipe is installed, and then a small one.
twin turbo (twinturbo) - this system is different from bi-turbo in that it is not aimed at reducing turbo lag or equalizing acceleration dynamics, but at increasing performance. In systems twinturbo (twinturbo) two identical turbines are used, respectively, the performance of such a turbocharging system is more efficient than systems with a single turbine. In addition, if you use 2 small turbines, similar in performance to one large one, you can reduce unwanted turbolag. But this does not mean that no one uses two large turbines. For example, a serious dredge might use two large turbines for even more performance. System twin turbo can work both on V-shaped motors and on in-line ones. The sequence of turning on the turbines can vary, as well as on biturbo systems. 
In general, for even more fun, no one bothers you to stick 3 (!) Turbines or more at once. The goal is the same as for twinturbo. I must say that this is often used in drag racing and never on stock cars.
At the same time as the market launch of the new BMW 3 Series Sedan, 4 high-torque and economical engines based on BMW TwinPower Turbo technology were introduced. These engines will be the heart of the new BMW 3 Series Sedan. Modern and responsive 2-litre engines with BMW TwinPower Turbo technology are the most powerful power units in a new generation of four-cylinder petrol engines. The technological basis for their creation was the award-winning six-cylinder gasoline engine. According to the development strategy of the BMW EfficientDynamics program, the task set for the design of new engines was to improve dynamic characteristics while reducing fuel consumption and toxic emissions. The new BMW 3 Series Sedan will also be powered by the proven 2.0-litre, four-cylinder BMW TwinPower Turbo diesel engine, delivering the same high output, but now more economical and less toxic. The aluminum alloy crankcase engine sets standards in many ways and combines the latest generation common-rail direct injection system with a variable turbine geometry turbocharger. The BMW 335i is emphatically sporty: with high torque power point 225 kW (306 hp) accelerates the BMW 3 Series Sedan from 0 to 100 km/h in just 5.5 seconds, consuming an average of 7.9 l/100 km and CO2 emissions of 186 g/km. The BMW 328i and BMW 320i are characterized by impressively high dynamism and efficiency. The BMW 328i takes only 5.9 seconds to accelerate from standstill to 100 km/h, with fuel consumption of only 6.4 l/100 km and CO2 emissions of 149 g/km. The sporty character of the BMW 320i is evident in the acceleration from 0 to 100 km/h in 7.3 seconds, and the 135 kW (184 hp) engine, which consumes an average of 6.1 to 6.3 liters of fuel, will allow you to get continuous pleasure from economical driving. The diesel engine of the BMW 320d has an output of 135 kW (184 hp) and consumes only 4.4 to 4.5 liters per 100 kilometers with CO2 emissions of 117-118 g/km. The use of optional BMW BluePerformance technology means that the BMW 320d already today meets the EU6 requirements, which will come into force as early as 2014.
