Abstract
The University of Rostock and IAV GmbH introduce a new approach to optimize the knock control in gasoline engines in this paper. The new knock controller permits a higher power output of the engine, without raising the level of knock probability. In contrast to conventional approaches, information about cylinder pressure is used to estimate the distance to knock limit. The ignition angle is controlled very closely to this limit without exceeding it. The resulting improvement in power output is proven using engine tests. The PhD thesis containing this work was decorated with the award “Hermann Appel Preis 2007” founded by the IAV GmbH.
