A method is provided for exercising an engine-driven, electrical generator. The generator has a first operation mode wherein the generator generates a predetermined output voltage at a predetermined frequency with the engine running a predetermined operating speed and a second exercise mode. The method includes the step of running the engine at a predetermined exercise speed with the generator in the exercise mode. The predetermined exercise speed is in the range of 40% to 70% of the predetermined operating speed of the engine. In addition, in the exercise mode, the generator generates an exercise voltage that is less than the predetermined output voltage.

Method for exercising a stand-by electrical generator

A method is provided for cooling an engine driven, electrical generator set and for reducing the fan noise associated with operation of the same. The method includes positioning a fan on the first side of the radiator. The temperature adjacent a first side of the radiator is monitored and the fan is rotated in response to the temperature of the air on the first side of the radiator exceeding a threshold. The fan urges air through the radiator in order to cool the engine coolant flowing therethrough.

Method and apparatus for reducing fan noise in an electrical generator

A method is provided for controlling a bi-fuel generator set. The generator set includes a controller, a generator for generating electrical power, and an engine for driving the generator. A flow of gaseous fuel is provided, and operation of the engine and the generator is monitored. The flow of gaseous fuel is adjusted in response to various predetermined operating conditions on the engine. In addition, the flow of gaseous fuel may be selectively passed through a charge cooler remote from a radiator for the engine. The flow of gaseous fuel may be cooled by the charge cooler in response to certain operating conditions on the engine.

Method of controlling a bi-fuel generator set

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.

Air flow arrangement for generator enclosure

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.

Generator structure incorporating multiple electrical generator sets

An apparatus has first and second driven pulleys for powering an engine auxiliary function, e.g., a water pump, and for driving an engine fan, respectively. The apparatus includes a hollow tube-like arbor fixed with respect to the first pulley and having a first arbor surface, e.g., an exterior cylindrical surface. A bearing has a first load-supporting surface, e.g., the interior surface of the bearing, which is mounted to the first arbor surface. A fan drive member is mounted to the second load-supporting surface of the bearing, e.g., the exterior bearing surface, and both the fan and the second pulley are coupled to the fan drive member. The two pulleys are driven by respective belts powered by the engine crankshaft and the pulleys rotate in opposite directions when driven. A new engine incorporating the apparatus is also disclosed.
