Abstract: A control system for a standby generator includes a control box mounted in a standby generator enclosure with a control panel coupled to the control box that is selectively openable to provide access into the control box. One or more fasteners may be mounted to the control panel to selectively hold the control panel closed, and one or more generator control components may be mounted in the control box and operated by the control panel.

Abstract: A standby generator having an engine with oil drain tube that facilitates removal of engine oil from the standby generator is disclosed. The standby generator includes an enclosure comprising a plurality of sidewalls, with an opening formed in one of the sidewalls, and an engine positioned within the enclosure. The engine further includes an oil drain and an oil drain tube having a first end coupled to the oil drain and a second end that opens and closes to selectively drain oil from the engine, the oil drain tube being positionable so as to extend out through the opening. The opening in the one of the sidewalls is lower than the oil drain, such that the oil drain tube is positioned with a downward angle when extending from the oil drain and out of the enclosure through the opening.

Abstract: A cylinder head and push rod tube configuration for an internal combustion engine is disclosed. The cylinder head includes a first end comprising a recessed rocker arm cavity. The cylinder head also includes a second end opposite the first end and defining an upper end of a combustion chamber. The recessed rocker arm cavity has a lower surface with a pair of push rod tube bores therethrough. The second end of the cylinder head has a pair of push rod tubes positioned in the push rod tube bores between the recessed rocker arm cavity and the second end. An intake port and an exhaust port each extend through the cylinder head to the combustion chamber.

Abstract: A cylinder head for an internal combustion engine is disclosed having an intake port geometry configured to reduce fuel puddling and improve fuel atomization. The cylinder head includes a housing having a recess defining a top portion of a combustion chamber. The cylinder head further includes intake and exhaust ports defined by channels extending from the top portion of the combustion chamber to an outer end of the housing. An intake valve is positioned within the cylinder head to control communication of the intake port with the combustion chamber, and an exhaust valve is positioned within the cylinder head to control communication of the exhaust port with the combustion chamber. The intake port further includes a cross-section having a modified D-shape with a single 90 degree corner. The modified D-shape cross-section extends substantially a length of the intake port.

Abstract: An air flow guide/diverter is disclosed for mounting to a cylinder head of an internal combustion engine. The air diverter directs cooling air to multiple locations on the cylinder head. The air diverter includes a main diverter shield having a proximal end extending from a cooling source to a distal end extending to the rear of the internal combustion engine. The air diverter includes a first arcuate member attached to the main diverter shield between the proximal end and the distal end of the main diverter shield, and a second arcuate member connected to the main diverter shield near the distal end of the main diverter shield. The air flow guide creates multiple channels of air to provide more efficient cooling with little added cost.

Abstract: A system for a flywheel assembly for use in conjunction with an internal combustion engine is disclosed. The flywheel assembly includes a flywheel in rotational association with a crankshaft of the internal combustion engine. The flywheel assembly further includes a cooling fan mounted over the flywheel, and capable of rotation therewith. The cooling fan and the flywheel are secured in a constant axial position relative to the crankshaft by virtue of a drive-cup and a retaining nut. Further, the flywheel includes a plurality of integrally formed, intersecting support ribs, for providing excellent dynamic stiffening (e.g., damping) capabilities to the flywheel assembly for substantially reducing and/or eliminating radiated noise.

Abstract: An air intake component and assembly, as well as an associated carburetor assembly and related method of assembly, are disclosed. In at least some embodiments, the intake component includes a surface capable of being coupled at least indirectly to a carburetor assembly, where the surface includes first and second orifices, a first channel capable of communicating engine intake air from a first location to the first orifice of the surface, and a second channel by which at least one of the first location and a second location is connected to the second orifice. The second channel is capable of communicating at least one of a primer air pressure pulse from the at least one location to the second orifice and fuel fumes from the second orifice to the at least one location. In at least some further embodiments, the intake component can be fitted with any of several interchangeable covers.

Abstract: A V-twin engine having a crankcase and a pair of cylinders defining a V-space therebetween, wherein the V-space is substantially enclosed, and a carburetor is positioned within the V-space. An intake air preheating arrangement supplies heated intake air to the carburetor, and a carburetor heating arrangement heats the V-space and the carburetor which is positioned within the V-space. Each of the foregoing arrangements, used separately or in combination within one another, aids in preventing “freeze-up” of the carburetor during running of the engine in a cold environment.
