  "textContent": "A misfire detecting portion executes a misfire detection control that involves evaluating the presence or absence of a misfire in the engine on the basis of the angular speed computed by the angular speed computing portion, and outputting an alert signal for informing about a misfire when a misfire is present. A learning portion conducts learning of the operational parameter on the basis of the detection value of the sensor when the engine rotation speed is within a predetermined first range that is larger than a predetermined idling rotation speed. A learning completion evaluating portion evaluates whether learning by the learning portion is completed. A misfire detecting portion conducts misfire detection control under the condition that the learning is completed. The misfire detecting portion does not conduct misfire detection control when the learning is not completed.",
