    摘要： A misfire detecting method in which misfire detection is carried out based on a rotating condition of an output shaft (7) of an internal combustion engine. A volumetric efficiency of the internal combustion engine is detected, and the misfire detection is prohibited when the detected volumetric efficiency is smaller than a predetermined load condition discrimination value.

    摘要： In an engine, the elapsed time for rotation through 30 degrees crank angle near top dead center of the compression stroke and the elapsed time for rotation through 30 degrees crank angle near 90 degrees after top dead center of the compression stroke are found and the amount of torque fluctuation is found from these elapsed times. Whether the vehicle is driving on a rough road is judged from the amount of fluctuation of the angular velocity of the crankshaft. When it is judged that the vehicle is driving on a rough road, the correction of the air-fuel ratio based on the amount of torque fluctuation is prohibited.

    摘要： A misfire detecting method wherein, when a judgement that an internal combustion engine is operated in a special condition in which a load on the internal combustion engine suddenly varies is made, the detection of misfire is prohibited, to prevent the occurrence of erroneous detection. When a judgement that the current time is immediately after an engine has been started is made (S3), or when a judgement that the current time is immediately after an ignition key has been turned off is made (S4), or when a judgement that a deceleration operation of the engine, a speed changing operation of a transmission or the rough load running of a vehicle is carried out is made (S5-S7), a processor repeatedly performing misfire detecting processes aborts a misfire detecting process in the present cycle immediately to avoid the occurrence of erroneous detection which is liable to happen when the vehicle runs on a rough road and so on.

    摘要： Engine speed variations following combustion events within the cylinders of a multi-cylinder internal combustion engine are compared with a threshold (12) during a predetermined number of combustion events. A distribution of speed variations exceeding the threshold with respect to the cylinders is formed (14). The distribution is analysed (17) to determine whether misfire is occurring, as indicated by speed variation following combustion occurring in half or less than half of the cylinders, or whether the vehicle is driving over a rough surface, as indicated by speed variation following combustion occurring in more than half of the cylinders.
