    摘要： An engine includes an angular velocity detecting means 10 for detecting a rotation angular velocity of a crankshaft 11 of the engine, a torque generated by the engine detecting means for detecting a variability of the angular velocity amplitude obtained by the angular velocity detecting means 10 as the variability of the torque generated by the engine. The engine compensates a fuel injection quantity by comparing the angular velocity amplitude detected by the angular velocity detecting means with the adequate angular velocity amplitude.

    摘要： Provided is an engine rpm control device which gradually reduces the output speed of an engine drive object when reducing the engine rpm. The engine rpm control device (20) includes a target engine rpm correction means used upon detection of an engine failure. The target engine rpm correction means has a storage device (51) containing a map of the correlation characteristic between the engine rpm and the output speed of object to be driven by an engine (100). The target engine rpm correction means corrects the target engine rpm so that an instructed engine rpm (Nset) or a derating target engine rpm (Nset') is shifted to a predetermined failure-preventing engine rpm (N2) while maintaining the reduction ratio of the output speed of the drive object at a predetermined ratio.
