An engine includes an angular velocity detecting meansfor detecting a rotation angular velocity of a crankshaftof 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 meansas 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.

Engine

A cetane number detection device in which an angular velocity detection device () for detecting the rotation angular velocity of the crankshaft () of an engine (), and which detects a variation in the value of the amplitude of the angular velocity detected by the angular velocity detection device () as a variation in cetane number.
