Abstract
The aim of this work is to develop an improved method for knock control in gasoline engines. This should enable higher power output compared to existing methods of knock control without raising the level of knock probability. An analysis of a known knock controller shows, that information about distance to knock limit is not used in knock control. Based on this analysis a design of a new knock controller is developed. This controller uses cylinder-pressure signals to estimate the distance to knock limit and to control ignition angle. An improvement in power output is proven using engine tests.
