Apparatus for detecting misfire in multicylinder internal combustion engines |
摘要 |
An apparatus for detecting occurrence of misfire in a multicylinder internal combustion engine detects a rotational speed of the engine in each expansion stroke of each cylinder, calculates a change of the engine rotational speed fluctuation quantity in accordance with a value of the detected rotational speed, and sets a misfire determination value for each cylinder based upon a determination result of the engine operating condition. Misfire determination is made for each cylinder based upon the misfire determination value for each cylinder and the change of the rotational speed fluctuation quantity, thereby elevating the accuracy of detecting occurrence of misfire in each cylinder.
