Abstract

The device comprises a post-combustion chamber bounded by a casing and connected to the engine exhaust pipe, a blower driven by the engine for sending additional air into the post-combustion chamber and a heat-exchanger for pre-heating the additional air by the exhaust gases from the post-combustion chamber. The pos-combustion chamber and the heat-exchanger are constituted by three co-axial cylinders, the assembly being arranged so that the exhaust gases are introduced into the axis and at the center of the post-combustion chamber, the outer cylinder and the intermediate cylinder defining a peripheral zone in which the additional air circulates. The intermediate cylinder and the inner cylinder define an intermediate zone in which the exhaust gases from the combustion chamber circulate in countercurrent to the additional air. The device is useful for two-stroke, four-stroke and rotary piston engines.
