Abstract
The objective of the present invention is to provide an engine with improved startability and stable operation regardless of the driving environment and usage conditions. The engine is equipped with a control means, which calculates a standard injection timing on the basis of the target rotational frequency of the engine and a standard injection amount, that is, the amount of fuel injected, and which corrects the standard injection timing using at least one correction amount. A fuel injection control unit calculates a cooling water correction amount on the basis of the target rotational frequency of the engine, the standard injection amount, and the cooling water temperature, and when the cooling water temperature is less than a first prescribed temperature the control unit corrects the standard injection timing using only the cooling water correction amount.
