還元装置。The blow-by gas flow control valve includes a blow-by gas flow control valve disposed in the middle of the blow-by gas passage of the engine, a temperature switch that closes only when the outside temperature is below about zero degrees Celsius, and an engine switch that closes only when the engine is not operating. The flow control valve includes a cylindrical valve housing having an inlet port and an outlet port on both end walls, and is arranged in the axial direction within the valve housing, and has an effective opening area of the inlet port and an effective opening area of the outlet port. a tapered valve member having a variable opening area; and an end wall on the side where the outlet port is provided, and the valve member is arranged between the valve member and the valve member, and the valve member increases the effective opening area of the outlet port. and a PTC heater attached to the valve housing, and the temperature switch and the engine switch are connected in series to the PTC heater. The engine's blow-by gas reduction device is a special feature.
