Abstract
An engine housing assembly (1) has a cover (2) and a body (4). Longitudinal baffles (10, 12 and 17) on cover (2) cooperate with baffles (13, 14, 60 and 61) on body (4) to seal against engine (8), to provide a first chamber (16) adjacent the intake side of the engine, and a second chamber (50) adjacent the exhaust side of the engine. An inlet opening (22) and exhaust opening (24) in body (4) facilitate movement of the air through the housing by fan (45) to restrict recirculation of engine heat in the housing, thus minimizing vapor lock. An opening (33) between baffles (17 and 16) allows a flow of heated air from the exhaust side of the engine over carburetor (44) to minimize carburetor icing.
