Simulation and Investigation Effect of Different Parameters on Ion Current Signal in SI Engines

The application of ion current signals is one of the most recent approaches in engine management systems. Nowadays, this signal is used for control of some parameters such as; air to fuel ratio, spark advance, knock and misfire in internal combustion engines. Weak signal makes some problems for detection and weak detection can not be used for optimal implementation. Therefore investigation of parameters that affects on this signal is important. In this paper the effects of different parameters on ion current signal in SI engines, such as; temperature, equivalence ratio, fuel type, engine load, humidity, EGR and carbon deposits are investigated.
