Abstract
The exhaust muffler comprises a body (12) of ceramic material which is enclosed within a metal case (1) defining an inlet chamber (16) and an outlet chamber (18) for the exhaust gases. A blanket (20, 22) of refractory fibres resisting high temperatures, assembled with a very small amount of binder and substantially without water of constitution, is highly compressed between the body (12) and the case. A sealing element (24) surrounding the body (12) is interposed between the blanket and the gas outlet chamber (18).
