An engine is provided with a fuel injection device, a state determination unit (58), an atmospheric pressure sensor, and an injection period control unit. The state determination unit (58) determines whether the engine is in a steady or transient state. The atmospheric pressure sensor detects the atmospheric pressure. The injection period control unit performs a steady process for calculating the fuel injection period in a steady state, a transient process for calculating the fuel injection period in a transient state, and an atmospheric pressure correction process for correcting the fuel injection period on the basis of the atmospheric pressure. The injection period control unit changes either whether or not the atmospheric pressure correction process is performed or the contents of the atmospheric pressure correction process, between cases when the engine state is steady and cases when the engine state is transient. |
