SYSTEM AND METHOD FOR ALERTING AND SUPPRESSION OF DETONATION AND/OR PRE IGNITION PHENOMENA IN INTERNAL COMBUSTION ENGINES BY MONITORING RPM FLUCTUATION

摘要

An engine system with advance detection of detonation and/or pre ignition, the system comprising an engine, operative for propulsion of a vehicle by generating rotational motion, whose rotational velocity over time is monitored; and a detonation and/or pre ignition detector operative to provide an alert for impending detonation and/or pre ignition of the engine, if the rotational velocity fluctuates over time to an extent which is predetermined to be unsafe.
