  • Publication number: 20190383704
    Abstract: To provide a controller for an internal combustion engine which can determine presence or absence of misfire with good accuracy, even when the rotational variation occurs due to factors other than misfire. A controller for an internal combustion engine calculates, as a reference detection period, the detection period detected within a reference angle interval including a top dead center; calculates a period deviation which is a deviation between the reference detection period and the each detection period; calculates a former period deviation integration value by integrating the period deviation in a former angle interval before the top dead center; calculates a later period deviation integration value by integrating the period deviation in a later angle interval after the top dead center; and determines presence or absence of misfire in the combustion stroke based on the former period deviation integration value and the later period deviation integration value.
