ABSTRACT:
A system and method compensates for systematic irregularities in measured engine velocities caused by torsional flexing in the crankshaft during rotation to improve the accuracy of misfire detection. A set of generated correction factors is stored in a table that are derived empirically using a test engine. The correction factors are adjusted during on-board operation of the engine whenever a safe adaptation time is determined.
