ABSTRACT:
A misfire detection method and apparatus includes measurement of combustion induced torque in an internal combustion engine and provision of time-ordered first, second, and third acceleration data samples dependent on the torque. A misfire is indicated when a magnitude of the second acceleration data sample has a magnitude less than a misfire threshold, and less than a magnitude of both the first and third acceleration data samples.
