Abstract: A misfire detection system and method measures fluctuations of air charge ingested into an engine (303) preferably as fluctuations of the engine's intake air pressure or as fluctuations of the mass air flow. A misfire indication (337) is provided dependent on a behavior of the fluctuations of air charge. Preferably, to eliminate errors associated with engine transient operating conditions, such as acceleration, the fluctuations of air charge are differentiated (325) before a misfire detection mechanism (333) is used to determine misfire behavior.

Abstract: A modified trimmed mean filtering method and apparatus for a misfire detection includes acquiring a time-continuous series of acceleration data samples (601) representative of acceleration behavior of a reciprocating engine. And, providing a filtered acceleration data sample (607) dependent on an average acceleration magnitude of a portion of the acceleration data samples bounded within a range of amplitudes and, preferably, a time-centered acceleration data sample (606) of the fixed length time-continuous series of acceleration data samples. A misfire condition can be indicated (409) dependent on a magnitude of the filtered acceleration data sample.

Abstract: A method for detrending engine positional data includes acquiring positional encoder data over a plurality of consecutive engine revolutions as the engine is decelerating. Then, a trend (207) in the acquired positional encoder data consistent with behavior occurring at less than a frequency of one cycle per engine revolution is identified. Next, corrected positional encoder data (208) is generated dependent on removing the identified trend (207).
