エンジンの排気装置。 A first on-off valve that opens when supercharging and closes when non-supercharging, an exhaust turbine of a supercharger, and an exhaust gas are installed in a first exhaust passage extending from the exhaust port of the front bank of the V-type horizontal engine. The purifiers are arranged in this order when viewed from the engine, and the second exhaust passage extending from the exhaust port of the rear bank of the engine is connected to the first exhaust passage between the exhaust turbine and the exhaust purifier.
A second on-off valve that joins the exhaust passage and closes during supercharging and opens when not supercharged is disposed in the second exhaust passage, and a portion of the second exhaust passage upstream of the second on-off valve is connected to the second exhaust passage. An exhaust system for a V-type horizontal engine with a supercharger, characterized in that the exhaust system communicates with the first exhaust passage upstream of the first on-off valve.
