PURPOSE: An abnormal combustion monitoring method of a cylinder is provided to repair promptly and regulate harmful exhaust gas by checking and alarming cause of vibration of an engine to a driver with detecting knocking, misfire, partial burning and unbalanced combustion between cylinders. CONSTITUTION: The angular acceleration of each cylinder is measured, and knocking is controlled by detecting knocking in sensing different angular acceleration(ST10,ST20,ST30). Misfire is detected in not knocking, and rpm of the engine is compared with the reference value at misfire(ST40,ST50). The engine warning lamp is turned on after enriching fuel in case of rpm of the engine to be over the reference value(ST60,ST70). Stabilization of the engine is decided in case of rpm of the engine to be less than the reference value(ST80,ST90). The engine warning lamp is turned on by deciding unbalanced combustion between cylinders in stabilizing the engine and deciding partial combustion in not stabilizing the engine(ST100,ST110). The engine warning lamp is turned on with checking over three times in deciding the partial combustion(ST120,ST130,ST140).
