    • The frequency characteristics of such influences of an output torque calculated with a dynamic model and outputted from a motor as are applied to the rotational fluctuations of a crankshaft, and the amplitude (P) and the phase (R) at the time of a damping control by the motor are used to calculate (at S110) an influence component (N30m) based on a 30-degree speed (N30), as the time period needed for the crankshaft of every 30 degrees to rotate by 30 degrees. An influence component (T30m) as the inverse of the influence component (N30m) is subtracted from a 30-degree required time period (T30) thereby to calculate a judging required time period (T30j) (at S120 and S130). The deciding required time period (T30j) calculated is compared with a threshold value (Tref) (at S140) to decide a misfire of the engine. As a result, the misfire of the engine for outputting the power to an after stage through a damper can be judged more reliably and precisely.

Date May 2, 1996A method is proposed for monitoring operations of an internal combustion engine to detect combustion misses for internal combustion engines having dual spark coils. A method is provided for the primary-side monitoring of the spark voltage and/or of the spark duration, and a method is provided for detecting irregular operations. If a faulty ignition is detected in one cylinder at one spark plug by monitoring the spark voltage and/or the spark duration, the second spark plug in this cylinder is then cut off (de-energized) and the reaction to this cut-off is monitored by means of the method for detecting irregular running. If the irregular running detection confirms faulty operation of the internal combustion engine, then the faulty ignition at the first spark plug of a cylinder was correctly recognized and appropriate emergency measures are introduced.
