12-cylinder engine BMW

The 12-cylinder engine established on cars BMW of 7 Series, - a limit of technological perfection on the given site of the market. Engines are supplied by system Valvetronic which regulates position of 24 inlet valves. Thanks to it extremely exact control of giving of air in a zone of burning of the engine is carried out, reducing the expense of fuel and emission of the fulfilled gases. Thanks to high degree of compression direct injection of fuel provides the maximum capacity in 327 кВ (445 ПС). The technology does not demand inlet collectors: fuel is injected directly into each cylinder, mixing up with air before. The big 6-litre engine develops full capacity, reaching the maximum value of the twisting moment, economy of fuel and the control over level of emissions. In a combination to such innovations as system of work of valves Double-Vanos, the generator cooled by a liquid or system of emission with близкорасположенными to the engine catalysts and system рециркуляции the fulfilled gases power units of this design rise on new level of perfection.
