LOAD CONTROL METHOD DURING ENGINE MISFIRE AND LOAD CONTROL SYSTEM DURING SAME MISFIRE

摘要

A load control method at the time of a misfire of the engine and a load control system at the time of the misfire are disclosed in which an output limit rate is calculated by calculating an additional stress with respect to a crankshaft from a torsional vibration of the crankshaft, A first step of calculating an additional stress with respect to the crankshaft based on a vector sum of the crankshaft torsional vibration exciter force at the time of detection of misfire; A second step of determining whether or not the calculated additional stress exceeds a permissible stress with respect to the crankshaft; and a control step of controlling the engine to reduce the operation output of the engine by a predetermined amount when the calculated additional stress exceeds an allowable stress, returning to the first step, If it is determined that the additional stress on the crankshaft is less than the allowable stress on the crankshaft, the additional stress on the crankshaft is increased And characterized in that it comprises a fourth step of controlling the driving output of the engine on the basis of the third step, the output limit ratio to obtain the output limit ratio.
