Operating method for direct injection internal combustion engine involves control unit setting relevant parameter to produce knocking on rota basis for defined cleaning interval

摘要

The method involves operating the engine with knocking combustion on a rota basis for a defined cleaning interval (R) with corresp. setting of a parameter (ZZP), e.g. the ignition timing, by the control unit that is set to prevent knocking for normal engine operation. The duration and state of the cleaning interval are defined by the control unit.
