发明名称 Method and engine control unit to detect combustion misses in part-engine operation
摘要 In a method for detecting combustion misses in cylinders of a combustion engine in part-engine operation in which only some of the cylinders are operated by the injection of fuel, a positional angle of the crankshaft is assigned to an angle segment; each angle segment is assigned to the particular cylinder which predominantly provides the torque for moving the crankshaft through the angle segment; an irregular running datum is determined as a function of a difference of segment pass-through times of immediately successive angle segments; and a combustion miss is detected if the irregular running datum exceeds or undershoots a limit value. In part-engine operation, the irregular running datum is determined only for two successive angle segments that are assigned to a combusting cylinder and to a non-combusting cylinder.
