METHOD AND APPARATUS FOR DETECTING COMBUSTION PHASE OF ENGINE

Disclosed are a method and an apparatus of detecting a combustion phase of an engine by an angular acceleration signal and combustion data of a single cylinder. The method may include calculating a point of maximum angular acceleration of each engine cylinder during an explosion stroke, detecting a combustion phase of an engine cylinder provided with a combustion pressure sensor, calculating a time difference between the point of maximum angular acceleration and the combustion phase of the engine cylinder provided with the combustion pressure sensor, and determining a combustion phase of an engine cylinder where the combustion pressure sensor is not mounted by using the time difference and the point of maximum angular acceleration of the engine cylinder where the combustion pressure sensor is not mounted.
