AIR-COOLING APPARATUS FOR AUTOMOTIVE ENGINE

摘要

A vehicle is provided which has an engine space having an opening arrangement for the admission of air when the vehicle is in motion. Air moves into the engine space along a determinable passage. An engine is arranged in the engine space in intercepting relationship with the passage to be cooled by air flowing therethrough. The engine includes a double wall exterior forming an air jacket into which air is forced under pressure by a blower in order to provide a second source of cooling for the engine. The double wall exterior includes inner and outer walls connected by heat transmitting plates and provided with cooling fins. The air jacket is connected to a passenger space into which heated air is admitted by a shut-off valve. The engine may have cylinders arranged either longitudinally or laterally of the vehicle and the forced air cooling may be provided in such a manner as to be in opposite direction to the natural cooling through the aforesaid space.
