    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 method and apparatus for adaptive profile correction for rotating position encoders in reciprocating engines measures a raw engine speed derived from a rotating position encoder (107) driven by a reciprocating engine. A first corrected engine speed (1103) is provided dependent on the raw engine speed and a predetermined first encoder profile while the engine is operating bounded within a first speed range (905), and a second corrected engine speed (1103) is provided dependent on the raw engine speed and a predetermined second encoder profile while the engine is operating bounded within a second speed range (903). A microcontroller (1205) derives a processed acceleration signal (1207) dependent on the measured engine speed and provides it to an external acceleration based misfire detection system (1201) which provides a misfire indication (1203) back to the microcontroller (1205) if a combustion misfire behaviour is detected in the processed acceleration signal (1207).
