切替装置。 A dual cylinder body consisting of an inner cylinder and an outer cylinder is interposed in the middle of the exhaust pipe of the engine, and the inside of the inner cylinder is connected to the first cylinder.
In the exhaust passage, the gap between the inner cylinder and the outer cylinder is configured as a second exhaust passage, and a switching valve selectively introduces exhaust gas into both exhaust passages, the switching valve is rotatably provided between a horizontally closed position fitted to the upstream end of the inner cylinder and a vertically open position about a valve axis that intersects the inner cylinder in the radial direction. The exhaust gas inlet is configured with a butterfly valve, and is provided with an exhaust gas inlet having a diameter smaller than the inner diameter of the upstream end in a collecting case on the upstream side of the cylinder body and communicating with both the exhaust passages, so as to be close to and opposite to the upstream end of the inner cylinder. An engine exhaust gas switching device characterized by:
