り低く設定されたことを特徴とする過給機付エンジン。In a supercharged engine that is provided with a supercharger for the engine body and a heat riser that heats the intake air in the intake pipe with heated cooling water after cooling the engine body, the air flows into the heat riser. Here, a first return channel is provided that allows the cooling water that has been heat exchanged with the intake air to flow back from the heat riser to the radiator, and a second return channel that returns the cooling water from the engine body to the radiator.
A return waterway is provided, and an on-off valve is provided that closes the first return waterway and opens the second return waterway in conjunction with an increase in supercharging pressure due to operation of the turbocharger. A supercharged engine characterized in that a second thermostat is provided in each of the second return channels, and the valve opening temperature of the second thermostat is set lower than that of the first thermostat.
