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.
