Abstract: A combined generator set and air conditioning compressor drive system is disclosed for use in a mobile vehicle. The disclosed device includes an auxiliary engine, a compressor, and a motor-generator. When an external source of electricity is unavailable, the motor-generator is shaft driven by the auxiliary engine and operated as a generator to provide electricity to the vehicle. The compressor is also shaft driven. When an external source of electricity is available, the motor-generator operates as a motor so as to drive the compressor.

Abstract: An enclosed generator set (10) is provided having an engine (12) and a generator (14). An air cleaner preheater assembly (60) is in airflow communication with a source of ambient air and a source of preheated air to supply the engine (12) with air for use in the combustion process. The air cleaner preheater assembly (60) attaches to a bulkhead (28) which defines an ambient air compartment (36) and a preheated air compartment (38) on the generator set (10). An ambient air passage (68) and a preheated air passage (72) pass through a wall of air cleaner preheater assembly (60). A door (82) is pivotally mounted about an axis of rotation (86) perpendicular to a major surface of the door. The door (82) is variably positioned by a bimetal spring (110) between a first position wherein preheated airflow into the air cleaner preheater assembly (60) is at a maximum and a second position wherein ambient airflow into the air cleaner preheater assembly is at a maximum.

Abstract: An automatic choke apparatus is provided having a choke plate mounted for variable rotation in a carburetor between a closed position and an open position wherein a flow of air entering the carburetor is substantially obstructed in the closed position compared to the open position whereby the flow of fuel entering the engine is increased when in the closed position. The choke plate has a choke shaft arm for rotatably moving the choke plate. The automatic choke apparatus has a throttle plate downstream from the choke plate mounted for variable rotation in the carburetor between an open position wherein a flow of air and fuel mixture exiting the carburetor is at a maximum and a closed position wherein the flow of air and fuel mixture exiting the carburetor is at a minimum. The throttle plate has a throttle lever for rotatably miving the throttle plate.
