摘要： Systems and methods useful for detecting a combustion fault in a combustion engine include determining cylinder power density values for cylinders present on the engine during its operation and determining cylinder imbalance parameters for the cylinders, based on the cylinder power density values. The cylinder imbalance parameters are compared with a provided diagnostic threshold value.

摘要： Combustion within an internal combustion engine is diagnosed and includes monitoring crankshaft angular velocity and generating a combustion phasing value for a combustion chamber based on the crankshaft angular velocity. The combustion phasing value is compared to an expected combustion phasing value based on a predetermined start of injection crank angle and combustion phasing differences greater than an allowable combustion phasing difference are identified based on the comparison.
