An installation for purifying the exhaust fumes of an internal combustion engine in operation has a hot gas line (10) separated from the fuel supply that opens into the combustion air intake channel (4) and a catalysing element (7) through which the gas flows and which contains rare earths, in particular cerium, arranged in the line (10). The catalysing element (7) has an alloy body (9) of composition metal and the hot gas is moistened air or exhaust fumes from the engine.
