徴とする過給機付エンジン。 A first throttle valve is provided in the main intake passage, and a second throttle valve is provided downstream of the supercharger in the supercharging passage having the supercharger, and the first throttle valve opens at a set opening or more. In a supercharged engine in which the secondary air passage connected to the exhaust system is branched from the supercharging passage between the throttle valve and the first throttle valve, when the engine temperature is low, the second throttle valve starts to open. A supercharged engine characterized by being provided with a second throttle valve control means that sets the valve opening degree to be larger than when the engine temperature is high and also causes the second throttle valve to fully open when the first throttle valve is fully open. .
