PROBLEM TO BE SOLVED: To solve a problem that, when a low-temperature injection mode, for instance at cold start, is switched to a normal injection mode, engine rotation speed drops greatly for a moment and in some situations, misfire is caused.SOLUTION: An engine apparatus of the invention comprises an engine 1, a fuel injection device 49 for injecting fuel into the engine 1, a motor generator 74, a battery 76 connected to the motor generator 74. The fuel injection device 49 can execute plural injection control modes. The engine device is configured such that, in association with switching of the injection control mode in the fuel injection device 49, the motor generator 74 is driven as an electric motor with electric power of the battery 76, and driving force of the engine 1 is assisted with auxiliary driving force of the motor generator 74. |
