Title: IC engine knock control by ignition retardation - retarding ignition by load-dependent amt. based on sum of previous corrections stored in memory
Inventor: CZUB EKKHARDT DIPL ING
IPC: F02P5/152
Filed: 1992-02-26
Abstract: The method involves retarding ignition by an amt. (Rh) from a prescribed horizontal characteristic ( alpha v) corresp. to partial loading, which is obtd. from summation of late corrections (SK), as seen on a plot of ignition advance ( alpha z) against time (t). This amt. is taken from a knock memory and weighted with a factor dependent upon the load. Hence with a known occurrence of knock only a small retardation of the ignition is necessary and the engine can be operated close to the knock limit. ADVANTAGE - Engine operation is optimised with small number of occurrences of knock during changes of load, by stable control at relatively low cost.
