Abstract
A combustion engine having at least one outlet passage for expulsion of the burned gases. The outlet passage terminates at the outer surface of the engine and communicates with an exhaust pipe connected to the outer surface by a flange and an intervening gasket. A tubular liner is arranged in the outlet passage and forms an annular cavity together with the wall of the passage. The liner extends free from the outlet passage through the gasket and the flange into the adjoining exhaust pipe.
