ABSTRACT:
A value approximately corresponding to the amount of a change in mean effective pressure calculated on the basis of the revolution period of an engine is used for discrimination of a misfire. In detecting a misfired cylinder by comparing this misfire discriminating value with a slice level, a misfire detection at the coasting time is avoided. Further, a misfire discriminating value corresponding to a misfired cylinder is specified on the basis of a predetermined varying pattern of the discriminating value. The slice level is set to the proper value in accordance with this discriminating value.
