    摘要: A misfire detector detects a misfire in a cylinder based on a maximum value and the minimum value of the angular speed. A first crank angle range is defined in such a manner as to include a crank angle in which the angular speed is maximum during a power stroke. A second crank angle range is defined in such a manner as to include a crank angle in which the angular speed is minimum during the power stroke. The maximum value of the angular speed is calculated within the first crank angle range, and the minimum value of the angular speed is calculated within the second crank angle range. The calculated maximum and minimum values are brought close to actual values to enhance a reliability of the misfire detector.
