  • Publication number: 20150019112
    Abstract: Knocking and misfire are judged by detecting combustion ions generated in a combustion chamber with an ion sensor, obtaining an integral signal by integrating the ion signal, and comparing the integral signal with a misfire judgment value and a knocking judgment value based on a signal obtained by averaging integral signals of prescribed past cycles. It is possible to: reduce a computation load by detecting misfire and knocking with an identical ion sensor and carrying out a judgment treatment with identical judgment function logic; and detect trace knocking by setting a knocking judgment threshold value and hence increase the accuracy of ignition timing control.
