気装置。 An exhaust pipe for guiding exhaust gas from the engine is disposed within the exhaust duct, the exhaust duct is provided so that the lower surface of the exhaust duct is flush with the vehicle floor, and the exhaust duct is formed on the lower surface of the exhaust duct. An exhaust control valve that opens and closes an opening and a cross section of the exhaust duct is provided near the downstream side of the exhaust pipe in a flow path within the exhaust duct, and when the vehicle speed is below a predetermined value, exhaust gas is directed from the opening to the exhaust duct. discharge downwards,
When the vehicle speed exceeds the predetermined value, the exhaust gas is discharged from the exhaust port at the downstream end of the exhaust duct, and the opening is closed by the exhaust control valve on substantially the same plane as the lower surface of the exhaust duct. Features: Exhaust system for in-vehicle engines.
