How to Introduce the Mercedes-Benz 271 Engine?
1 Answers
Mercedes-Benz 271 Engine is designed with a base displacement of 1796cc. The engine is no longer named according to the displacement but based on the engine's output power. The supercharger is more efficient than the previous generation M111 engine, and the mid-range torque output is more ideal. Engine Smooth Operation Analysis Function: The engine operation is continuously monitored to prevent the three-way catalytic converter from being subjected to excessive thermal stress in case of poor combustion ignition. If the engine control module detects poor combustion ignition during smooth operation analysis, the corresponding fuel injector will no longer be activated after a certain number of ignition failures. However, a maximum of only two fuel injectors will be shut off simultaneously. Fuel Supply System Control Function: The M271 engine adopts a single-line fuel supply method. The fuel supply system is regulated and monitored by the engine control module and the fuel pump control module. The fuel pump draws fuel from the supply module and delivers it to the fuel rail through the fuel filter. The fuel pressure regulator is integrated inside the fuel filter, and the pressure relief valve limits the fuel pressure to approximately 380kPa. There is a check valve at the fuel supply point of the fuel filter to prevent fuel pressure from dropping when the fuel pump is turned off.
