Abstract

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.
