Operating direct injection internal combustion engine involves feeding fuel from high pressure region in which pressure depends on engine operating mode and operating point

摘要

The method involves feeding fuel from at least one high pressure pump in a fuel system high pressure region (20), whereby fuel passes from the high pressure region directly into at least one combustion chamber of the engine and the pressure in the high pressure region depends on the current operating point of the engine. The fuel pressure in the high pressure region also depends on the operating mode (B1-B3) in which the engine is being operated. AN Independent claim is also included for the following: a computer program for implementing the method and a control and/or regulating device for operating an internal combustion engine.
