Abstract:
1. An engine comprising: an engine torque detection means including an angular velocity detecting means for detecting a rotation angular velocity of a crankshaft of an engine, wherein the engine torque detection means detects a variability of an angular velocity amplitude obtained by the angular velocity detecting means as the variability of the torque generated by the engine; a load detecting means for detecting an engine load; a rotation number detecting means for detecting the engine rotation number; an injection quantity map for calculating the fuel injection quantity based on the load by the load detecting means and the rotation number by the rotation number detecting means; an angular velocity amplitude map that represents an assumed angular velocity amplitude that is defined by the rotation number detected by the rotation number detecting means and by the injection quantity calculated using the injection quantity map; and an injection quantity compensation means for compensating the injection quantity map by comparing the angular velocity amplitude detected by the engine torque detection means with the assumed angular velocity amplitude determined using the angular velocity amplitude map.
