Operating self-ignition internal combustion engine involves self-ignition of main injection event occurring after start and before end of high-temperature phase of pre-injection event

摘要

The method involves injecting fuel directly into a combustion chamber with an injection nozzle, whereby some fuel is injected as a pre-injection during a working cycle and the rest as a min injection at a later time and a homogeneous pre-mixture is formed for the pre-injection, with which a homogeneous combustion phase is initiated in the form of a low-temperature phase and a high-temperature phase. The self-ignition of a main injection event occurs after the start and before the end of the high-temperature phase of the pre-injection event.
