Title: Method and device for detecting the self-ignition threshold in internal combustion engines
Inventor: MOSER WINFRIED
IPC: F02P17/00
Filed: 1983-12-22
Abstract: A method and a device for detecting the self-ignition threshold of the compressed fuel/air mixture in internal combustion engines is proposed. For this, the pressure characteristic supplied by a pressure sensor (5) in a combustion chamber (3) of an internal combustion engine is processed in a computer (7) so that, in parallel with the instantaneous pressure characteristic, the energy conversion of the combustion as well as an auxiliary function are determined. By means of this auxiliary function, it is possible to specify a self-ignition threshold, i.e. to specify a limit, regardless of whether knocking combustion is occurring or not. In this way, a value which permits knocking to be controlled (8 to 13) can be determined. The invention is similarly suitable for spark-ignition and for self-ignition internal combustion engines. <IMAGE>
