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. |

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 over a plurality of rotational cycles of said rotational motion 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. |
