Title: IC engine knock control by ignition retardation - employing relay energised via idling speed detection and limit switches to transfer timing control from cylinder specific to idling 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) for the cylinder concerned, when knock is detected, as seen on a plot of ignition advance against time. Above idling speed the prescribed characteristic is read from a memory to activate the characteristic knock memory (KKS) from which the amt. of retardation is derived. When knock arises at idling speed from, e.g. regular fuel, hot weather, heavy auxiliary loading and severe pre-ignition by digital idling stabilisation (DLS), unnecessary retardation is suppressed so that smooth acceleration can take place. ADVANTAGE - Largely optimal engine operation is guaranteed during transitions from idling to higher ranges of power output.
