What is twin turbo on BMW. TwinPower Turbo on BMW motors than they differ and what their advantages
This allows you to arrange intake and outlet channels in such a way that their length is reduced at a larger cross section at the same time. Due to this, the pressure loss on the output of the exhaust gases is significantly reduced. The optimal bandwidth of the flow ensures the special design of the total exhaust manifold, the four pipes of which "serve" two cylinders. The separation of exhaust gases continues until it comes to the turbine wheel. Thus, a constant, free from no countercurrent pressure on both "snails" TWIN SCROLL turbocharger is created. The maximum pressurization pressure of the system is 1.5 bar. The use of double supervision technology Twin Scroll Twin Turbo with a common exhaust manifold of a special design allows you to additionally reveal the potential boosting capabilities. The new M TwinPower Turbo engine is distinguished by an exceptionally acute response characteristic and extremely high thrust, achieved at low speed and continuously retained to a high revolutions. All this is accompanied by a characteristic version of the BMW version of M, amazingly powerful and rolling sound of the engine, which emphasizes its revolutions and acute reaction to the addition of "gas". Developing high power The V8 engine has a corresponding cooling system designed individually for each model. It includes in particular indirect cooling of adequate air, which further improves the technical potential of the engine in particularly dynamic motion modes. The new TWINPOWER Turbo engine works with maximum efficiency. In addition to the high Precision Injection Injection Inject Injection, the M and BMW X6 M model is equipped with numerous BMW EfficientDynamics technologies: along with brake energy recovery, it is controlled by an electric fuel pump depending on the need, the air conditioner compressor is turned off, as well as regulatory consumption (and therefore Also functioning depending on the needs) of the hydraulic fluid in the body of suppression of the body rolls. Models have an average fuel consumption over the EU cycle of 13.9 liters per 100 kilometers. Emission CO2 of both models is 325 grams per kilometer. Cars are respecting the American Ecological Standard LEV II and the requirements of Euro 5 in Europe.

These new generation engines have become even more economical, environmentally friendly and powerful than their predecessors. Innovative technologies that are cornerstles of BMW EfficientDynamics strategies combine the latest fuel injection systems, the Valvetronic system, including Double-Vanos, as well as innovative turbocharging technologies. The result was the creation of particularly efficient power units, which brightly demonstrate the BMW experience in the area of \u200b\u200bthe Motor Station.
Diesel engines BMW TwinPower Turbo
BMW EfficientDynamics principles are embodied in Diesel engines BMW Twin Power: the combination of the highest fuel efficiency, increased power and excellent driving qualities. Cars with diesel engines can serve as samples of efficiency and dynamics. At the same time, 3-cylinder Diesel engines BMW TwinPower Turbo are ideal power-level power units; Innovative 4-cylinder engines BMW TwinPower Turbo and powerful 6-cylinder Diesel engines BMW TwinPower Turbo perform their work with extremely small harmful emissions and friction losses. Diesel units of the BMW EfficientDynamics family with lightweight aluminum design are equipped with turbochargers with a variable geometry and a direct-injection direct injection system of the last generation.
Simultaneously with the release to the market of the new BMW 3 sedan series, 4 engines featured high torques and efficiency and created using BMW TwinPower Turbo technology were presented. These engines will become the heart of the new BMW 3 sedan series. Modern and "responsive" 2-liter engines with BMW TWINPOWER Turbo technology are the most powerful power units in a new generation of four-cylinder gasoline engines. An award-winning six-cylinder gasoline engine served as a technological basis for their creation. According to the BMW EfficientDynamics Program Development Strategy, the task assigned to the design of new engines was reduced to improving dynamic characteristics while reducing fuel consumption and toxic emission volumes. The new BMW 3 series sedan will also be equipped with proven its effectiveness with a 2-liter four-cylinder Diesel engine BMW TwinPower Turbo, developing all the same high power, but now this engine has become more economical and less toxic. The engine with an aluminum alloy crankcase establishes standards in many respects and combines the latest generation direct injection system and the turbocharger with a variable turbine geometry. BMW 335i is emphasized Sports: With a high torque, a power plant with a capacity of 225 kW (306 liters) disperses the BMW 3 series sedan from 0 to 100 km / h in just 5.5 seconds, spending an average of 7.9 l / 100 km At the level of CO2 emissions in 186 g / km. For BMW 328i and BMW 320i are characteristic of impressively high dynamism and efficiency. BMW 328i takes only 5.9 seconds to accelerate up to 100 km / h, and the fuel consumption will be only 6.4 liters / 100 km, and the CO2 emission level is 149 g / km. The sports character of the BMW 320i is manifested in overclocking from 0 to 100 km / h in 7.3 seconds, and the engine with a capacity of 135 kW (184 liters), spending an average of 6.1 to 6.3 liters of fuel, will allow you to receive Permanent pleasure from economical driving. The BMW 320D diesel engine has a power of 135 kW (184 liters.) And spends only 4.4 to 4.5 liters per 100 km of way at CO2 emissions level in 117-118 g / km. Application of Optional BMW BluePerformance technology means that the BMW 320D today meet the requirements of the EU6 standard, which will take effect only in 2014.
On the way from the basic series to the sports supercar M5, the BMW brand has always challenged the laws of automotive logic. Cars that seemed incredibly fast on paper, exceeded all expectations when started in a series and in real acquaintance. Many, if not all BMW engines work, as if by magic, but when the hood opens the next Bavarian masterpiece, it does not turn out to be an ancient German runes under it, only "TwinPower Turbo" is shown on the protection of the power unit.
BWM always preached the turbocharging policy and rear drive. Today, do not meet the power unit of the brand, which has no at least one turbocharger, not to mention a series of high-performance diesel engines with three- and four-track installations.
TwinPower plays an important role when it comes to efficient and dynamic gasoline and diesel engines BMW. But what is TwinPower Turbo in reality and what can he offer to the automotive world?
When it comes to gasoline engines, TwinPower Turbo, that is, three components that are used in all modifications, from 3 to 12 cylinders:
Valtronik;
direct fuel injection;
Turbocharddv.
Turbodiesel rails are equipped with the Common Rail injection system.
Valvetronic - electronic variable valve. This technology developed by BMW, which allows you to optimize fuel consumption by adjusting the valve lift. The developers argue that this technology itself is capable of reduced fuel consumption by 10%.
Wolvetronik - Powerful electronic technology. It provides continuous and accurate control over the lifting valve. This means that when the Bavarian owner is pressed the gas pedal, the opening of the valves is started, instead of the usual throttle, the intake systems open.
The system uses a rocker set controlled by an electronic camshaft. Since it is capable of adjusting the valves from fully open to almost a closed state, the engine does not need turnover to increase the load.
Valvetronic was first introduced in 2001 on the 316TI series models and was used mainly for high-rise engines focused on massive sale, such as:
N42 STRAIGHT-4;
N52 Straight-6.
But the system was not used on a dual turbocharger N54. Instead, the Turbocaddv N55 Straight-6, replaced it in 2009 with the same characteristics as the N74 Twin-Turbo V12 of the top 7th series, was equipped with a Valtronik system. After that, the technology was used almost on all BMW cars.
High Precision Injection - direct injection systems with central multilay-mounted injectors. They gradually replaced the technologies used in the 2000s. Jets with a superior and turbocharged used piezo-sector nozzles. However, the new 6-cylinder turboformator BMW N55, launched in production since 2010, installed in models 335i, 535i, x3, x5 and x5, uses a solenoid injection system developed by Bosch. This system was chosen by Bavarians to maintain competitive prices in the North American automotive market.
TWINPOWER TURBO name has confused many car owners. They did not understand what was under the hoods of their BMW. In this regard, a lawsuit was filed with a lawsuit for a large number of people. TwinPower Turbo document was called the "false twin" and it was said that the Bavarians launched an advertising campaign in order to deceive buyers. It's all about the word "double", which is present in the title. Its presence was not a guarantee of equipping engines to two turbocharging.
Initially, TWINPOWER Turbo appeared on a two-ranking single turbocharging (installed on the 5th series Gran Turismo in 2009, and in 2010 there were models E90 335i, 135i, x3 and x5), starting with N55 (six-cylinder turbocharging engine) and N74 (6-liter V12 Aggregate with two turbocharging). They were equipped with models 760i and 750li 2009 release. Twin-speed turbocharging is the main technology for TwinPower Turbo BMW.
The design with two turbines begins with an exhaust manifold separating exhaust gases. They are conducted through different spirals called "scrolls". Turbo has two nozzles of different diameters, they are needed to ensure the rapid response of the power unit. BMW calls a special graduation manifold of its own development of Cylinder-Bank Comprehensive Manifold or CCM.
It should be reminded that modern BMW TwinPower engines are not necessarily equipped with two-stroke turbocharger. But they have an excellent graduation collector, which catches more exhaust gases to feed into the turbine, which provides power without lag.
Three-cylinder revolution: B37 and B38 TwinPower Turbo. Gasoline and diesel
Three-cylinder gasoline and diesel engines have become another revolutionary solution of BMW, which can compete with modifications having a greater number of cylinders. They are built according to a modular system where the same 500-centimeter cylinders are used in conjunction with TwinPower Turbo technology with a capacity of 120-220 horsepower.
It is known that diesel units received the designation B37, and gasoline - B38. The first samples are installed on the hybrid sports car of the I8 series FWD 1 and MINI. They are also used by the RWD 1 and 3 series as starting modifications of the modular row of engines.
Top 4-cylinder turbo in the world
In 2004, the engine production with a direct injection, developed in conjunction with PSA Peugeot Citroen. In 2011, BMW designers developed the N13 model in which the oil filter housing was changed - it was installed longitudinally. The engine was installed on the model 114i, 116i and 118i.
Perhaps a promising engine for BMW is now N20. Its working volume is 2.0 liters, there is a turbocharger with four cylinders. The motor also has the inscription "TwinPower Turbo" on the lid. This engine replaced the less powerful Street-6 fellow in the models "20i", "28i", is viable and very effective alternative.
There are 2 modifications N20. The 184 PS version is less powerful and is available for X1, XDrive20i, F30 320i, 520i, base Z4 SDRIVE20i. The top version of this 2.0-liter TWINPOWER engine has a capacity of 245 hp, used in F30 328i, 528i, x1, x3 and z4 models.
Straight-6 TwinPower Turbo: N55
When the TWINPOWER TURBO technology is installed on a 6-cylinder engine, its advantages become apparent. The motor with two Turbines N55 replaced the more expensive N54 unit in 2009. But both modifications are very similar to each other. Comparable access to its own 4-liter V8 BMW, with a lighter block and lower torque, even more tan, which can be found in E92 M3 with a powerful S65 V8.
The power of N55 is 302 hp, the torque is 300 nm (400 nm). It is installed in models 335i, 135i and all modifications of SUV. There is an even more powerful version under the index N55HP, with a capacity of 315 hp, torque of 450 nm. This version includes top models, such as 640i, 740i, and even sports superheavy Hatchback M140i.
The engine debut took place in 2009, it began to be installed on the fifth series GT. Equipped with an advanced version of the 6-cylinder engine, BMW 535i Gran Turismo is able to accelerate up to 100 km / h in just 6.3 seconds. The maximum speed of this beast is limited to 250 km / h. As for fuel consumption, the BMW 535i GT consumes 8.9 liters per 100 kilometers. CO2 emission rate - 209 g / km.
