    Abstract: PURPOSE: A combustion time discriminating method of a compression-ignition engine and an apparatus thereof are provided to control a direct injection type compression-ignition engine by analyzing the vibration signal of the engine block. CONSTITUTION: A combustion time discriminating method of a compression-ignition engine comprises following steps. A block vibration signal which is generated by the combustion of an engine is measured(S101).
