Mercedes-Benz M274 2.0T engine

We did not know before, like as seen in the domestic new Mercedes-Benz E-Class sedan that sets the code for the M274's longitudinal 2.0 l turbocharged engine, this is indeed disappointing, but the good news is that in 2014 year, Mercedes-Benz will be adjusted on the dynamic E-Class sedan, in addition, the new Mercedes-Benz C-Class, Mercedes-Benz GLK-Class models will also use this new engine.

In the Mercedes-Benz modular system, code-named M274's 2.0T engine used in longitudinal platform. The actual displacement of this engine is 1999mL, bore and stroke of 83mm and 92mm respectively, the compression ratio of 9.8: 1, audi a4 quattro turbo this parameter is set in line with the characteristics of a turbocharged engine.
Like many turbocharged engines, 2.0T's M274 engine also been adjusted to provide high and low-power two versions of the engine, including low-power version of the engine's maximum power of 184 hp and maximum torque of 300 N • m high power version of the engine which two data respectively 211 hp and 350 N • m. In order to weaken the turbo lag as much as possible to the driver bring bad driving experience, this station engineer 2.0T engine's maximum torque output speed is set at a 1250rpm, thereby enabling faster start acceleration response, intake and exhaust dual variable timing system and variable valve lift system which has played a key role. However, early intervention turbo engine at low speeds for fuel economy will have some impact.
The use of direct injection technology can make up for the above-mentioned fuel economy issue to some extent, M274 engine uses a third-generation Mercedes-Benz direct injection technology, piezo injectors can be achieved within a stroke engines fuel injection up to 5 times, and the injector direct injection system in general will only be two injections. audi a6 quattro turbo In order to keep pace with the action injectors, spark plug ignition system can support in thousandths of a second (one millisecond) for four consecutive discharges, in order to make the fuel burn more fully.
In other technical aspects, vw passat 1.8 turbo M274 naturally does not lag behind in its class, in addition to the above-mentioned gas distribution technology, variable-displacement oil pump and start the machine is equipped with high-power engine start-stop system and so are the engine of highlights.
