A silencer mounted close to the engine exhaust manifold defines a conical flow passage 2 leading to an annular passage 3 containing vanes which set up a swirl in the gases entering the expansion chamber 5 before entering the outlet pipe 12 via the passage 9 and the perforations 6. The flow of gas in the silencer serves to reduce the pressure in the exhaust manifold. <IMAGE> |
