ABSTRACT:
An apparatus and corresponding method for detecting misfires of a motor vehicle internal combustion engine. The apparatus includes a speed sensor for generating a signal. Also, the apparatus includes a filter means for filtering noise-related events from said signal corresponding to sensed engine speed to thereby produce a filtered output signal. In addition, a pressure sensor for measuring average manifold absolute pressure over a cylinder firing event to set a misfire threshold change in engine speed value is shown. A comparison means for comparing said filtered output signal with said threshold change in engine speed value to detect an engine misfire condition for said cylinder firing event is also included.
