Abstract: A generator structure is provided for generating electrical power. The generator structure includes an enclosure having first and second spaced sidewalls interconnected by first and second end walls so as to define an interior. First and second generator sets are positioned within the interior of the enclosure. Each generator set includes an engine, an alternator driven by the engine for generating the electrical power and a radiator operatively connected to the engine. Means are provided for synchronizing the electrical power generated by each alternator.

Abstract: A fan drive arrangement and method is provided for facilitating the cooling of engine coolant flowing through a radiator and an engine. The fan drive arrangement includes a variable pitch sheave assembly which moves between a first high speed position and a second low speed position. Variable pitch sheave assembly is interconnected by first and second drive belts to first and second drive pulleys operatively connected to the crankshaft of the engine and by first and second fan belts to corresponding fan pulleys connected to a fan shaft of a fan. Variable pitch sheave assembly includes first and second drive belt receiving grooves for receiving corresponding drive belts therein and first and second fan belt grooves for receiving corresponding fan belts therein. The depths of the fan belt grooves and the drive belt grooves of the variable pitch sheave assembly are varied in response to the temperature of the engine coolant flowing through the radiator so as to vary the fan speed accordingly.

Abstract: A generator structure is provided having an improved air flow arrangement. The generator structure includes an enclosure having an interior for receiving an engine and an alternator therein. A roof structure is positioned on the enclosure and includes an eave portion and an attic portion. The eave portion has an inlet which communicates with the ambient air external of the generator structure, an outlet communicating with the interior of the enclosure and input flow path therebetween. The attic portion has an inlet communicating with the interior of the enclosure, an outlet communicating with the ambient air external of the generator structure and an exit flow path therebetween. An air flow generator draws ambient air through the inlet flow path in the eave portion of the roof structure into the interior of the enclosure to cool the engine and the alternator and urges air from the interior of the enclosure through the exit flow path in the attic portion and out of the generator structure.
