Method for preventing pre-ignition of fuel-air mixture in cylindrical chamber of internal combustion engine with high compression ratio or turbo charging, involves operating internal combustion engine by Otto-engine

摘要

The method involves operating an internal combustion engine by Otto-engine. An associated cylindrical inner pressure and a position of center of gravity of combustion of the cylinders are determined for current operating cycle depending on the detected angular velocity gradient of the crankshaft of the internal combustion engine.
