Abstract
An engine generator set apparatus including an internal combustion engine including a drive shaft driving an electrical generator, the engine and the generator being disposed along a longitudinal axis. A housing substantially enclosing the engine and generator, the housing including air inlets and air outlets. A fan drawing outside ambient air through the air inlets in the housing and along an inlet air pathway, the generator being axially disposed intermediate of the fan and the engine.
Claims22
An engine generator set apparatus, comprising:
- an internal combustion engine including a drive shaft;
- an electrical generator driven by the drive shaft of the internal combustion engine, a longitudinal axis being defined through the drive shaft, the generator being disposed along the longitudinal axis;
- a housing substantially enclosing the engine and generator, the housing including air inlets and air outlets;
- a fan drawing outside ambient air through the air inlets in the housing and along an inlet air pathway, the generator being axially disposed intermediate of the fan and the engine;
- a heatsink attached to control electronics being disposed in the inlet air pathway and
- a radiator disposed with a major surface of the radiator facing substantially transversely of the longitudinal axis of the engine and the generator.
