    • PURPOSE: Method and device of detecting misfiring of an internal engine are provided to earlier detect what cylinder suffered misfiring, depending on the peak position of an angular velocity filtered by a band pass filter. CONSTITUTION: A method of detecting misfiring of an internal engine comprises next steps. The angular velocity of a rotating shaft and the position of the top dead center of a reference cylinder are detected. A rotating frequency depending on an angular velocity and another frequency depending on the rotating speed of an engine(30) are compared. It is determined whether misfiring occurred. If yes, then filtering is performed so that only a frequency corresponding to the rotating speed of an engine of signals depending on the angular velocity can pass. A pulse signal depending on the position of the top dead center of a reference cylinder is divided by the number of cylinders.
    • 目的:提供检测内部发动机失火的方法和装置,以便根据由带通滤波器滤波的角速度的峰值位置,早期检测出哪个气缸发生了失火。 构成:检测内部发动机的点火的方法包括以下步骤。 检测旋转轴的角速度和参考气缸的上死点的位置。 比较取决于角速度的旋转频率和取决于发动机(30)的转速的另一频率。 确定是否发生失火。 如果是,则进行滤波​​,使得只有与根据角速度的信号的发动机的转速相对应的频率才能通过。 取决于参考气缸上死点位置的脉冲信号除以气缸数。
