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.

主权项

1. An engine system with advance detection of detonation and/or pre ignition, the system comprising:
a turbocharged engine comprising a turbo waste gate, the turbocharged engine being 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 with a frequency which is predetermined to be unsafe, and a control coupled to said detonation and/or pre ignition detector and configured for selectively operating said turbo waste gate responsive to said alert being provided.
