ION CURRENT USE FOR COMBUSTION RESONANCE DETECTION, REDUCTION AND ENGINE CONTROL

摘要

A system and method for detection, reduction of combustion resonance and engine control is provided. The system senses ion current within one or each cylinder of a multi-cylinder engine and determines combustion resonance from the ion current signal. In addition, the system may determine an engine control strategy to reduce combustion resonance based on the feedback from the ion current signal.
