Abstract: A cooling system for an OHC type four-stroke cycle internal combustion engine having a valve chamber lubricated by oil mist. The system includes an accommodating space accommodating a transmission mechanism, a blower fan rotatably driven by a crankshaft, and a cooling air channel extending between a combustion chamber and the valve chamber disposed above the combustion chamber. The cooling air channel includes a primary air channel formed between intake and exhaust ports and extends toward a spark plug located on the downstream side of the cooling air channel. The cooling air channel also includes an air guide channel for guiding the air to an upstream inlet of the primary air channel and is defined by a wall which faces the upstream inlet of the primary air channel and extends laterally. The wall extends vertically in the accommodating space and is formed with an oil mist passage extending vertically therein.

Abstract: The present invention is directed to an auxiliary power unit for use with a vehicle, typically a truck. The power unit uses an air-cooled generator and associated auxiliary engine to supply power and air regulation requirements to the truck on demand. The air-cooled auxiliary engine is employed with an electrical generator and a compressor to provide the auxiliary power unit. The unit is self-contained in that it is not interconnected with the vehicle liquid coolant systems. A remote control module directs the operation of the power unit to supply heating and air conditioning to the vehicle interior by a sleeper unit. The sleeper unit provides a heating source and a coolant source that are powered by the power unit. A housing for the power unit is designed to assist in cooling and maintenance of the power unit. A series of air inlets are used to direct cooling air from the surrounding air over the generator, engine, and a condenser, so that operating temperatures of the power unit van be maintained within acceptable parameters. The housing also has an access cover that allows the contained power unit to be removed from the housing on a series of guides or channels, thereby facilitating the serviceability of the unit.
