Filed:

Mar 1, 2001

Appl. No.:

09/797231

Inventors:

Chris Turner - Whitewater WI
Christine Richardson - Delavan WI
Robert D. Kern - Waukesha WI
Gerald C. Ruehlow - Oconomowoc WI

Assignee:

Generac Power Systems, Inc. - Waukesha WI

International Classification:

H02K 900

US Classification:

310 58, 310 59, 290 1 B

Abstract:

An air flow structure is provided for controlling the flow of air through an enclosure of a generator. The enclosure has first and second opposite ends and the generator includes an alternator and an engine driving the alternator. A first air flow generator draws ambient air into the chamber through the first end of the enclosure and directs the first portion of air in the chamber across the engine. A second air flow generator draws a second portion of the air over the alternator, and thereafter, combines the first portion of air directed over the engine and the second portion of air drawn over the alternator. The second air flow generator urges the combined air from the enclosure through the second end thereof.

International Classification:

F02D 9/00

US Classification:

123438, 123402

Abstract:

A method and device is provided for regulating the air-fuel mixture provided to an engine of a stand-by electrical generator during the exercise thereof. The engine is exercised at a predetermined speed less than the normal operating speed of the engine and each cylinder receives an air-fuel mixture having an air component and a fuel component. To exercise the engine, the air component and the fuel component in the air-fuel mixture provided to the engine is reduced. In addition, the volume of the air-fuel mixture provided to each cylinder of the engine is balanced.

International Classification:

F02B 13/00

US Classification:

123575, 123527

Abstract:

A fuel selection device is provided for allowing a user to connect the cylinders of an internal combustion engine to a user-selected fuel source. The fuel selection device includes a housing that defines a cavity for receiving a moveable selector therein. The selector defining first, second, third and fourth flow paths. The first and second flow paths are used for flowing a first type (e. g. , natural gas) of fuel from a fuel source to the cylinders of the engine. The second and fourth flow paths are used for flowing a second type of fuel (e. g. , liquid propane vapor) from a fuel source to the cylinder. The selector is movable between a first position wherein first and second cylinders communicate with the first and second flow paths, respectively, and a second position wherein the first and second cylinders communicate with the second flow path and fourth flow paths, respectively.

International Classification:

H02K 7/18
H02K 9/02

US Classification:

290 1 A, 290 1 B

Abstract:

An electrical generator has an internal combustion engine and an alternator mounted to the engine and operative to generate electrical power during running of the engine. The alternator and the engine are arranged vertically to reduce the footprint of the electrical generator. The components of the electrical generator are contained within an enclosure defined by a base panel, a set of upright side panels, and a roof panel. When the roof panel is removed, each of the side panels can be independently removed from engagement with the base panel, which allows for easier access to the components of the electrical generator, such as for maintenance, service, and repair. The components are arranged so that cooling and exhaust air flow paths are defined within the enclosure.
