US Classification:

123198E

Abstract:

The present invention provides a four-stroke internal combustion engine having reduced noise emissions. The engine includes a filter element having substantially flat inlet and outlet sides, a first housing portion, and a second housing portion coupled to the first housing portion. The first and second housing portions define an air chamber in which the filter element is supported. The second housing portion includes an interior surface, at least one protrusion to space the inlet side of the filter element from the interior surface, and an air passageway. The outlet of the air passageway is positioned adjacent the interior surface to deliver air to the air chamber between the interior surface and the inlet side of the filter element. A ratio of the volume of the air chamber to the length of the air passageway is between about 5 inand about 20 in.

Abstract:

A standby generator includes a standby housing defining a cavity and an internal combustion engine. The engine includes an engine block including a cylinder comprising a piston, an engine housing at least partially covering the engine block, and a crankshaft configured to rotate about a vertical crankshaft axis in response to movement by the piston. The standby generator also includes an alternator configured to generate alternating current electrical power, a controller comprising a rectifier configured to convert the alternating current to a direct current and an inverter configured to convert the direct current to a clean alternating current electrical power, and a transfer switch configured to receive the clean alternating current electrical power from the controller and at least one of grid, solar, or battery power, and configured to supply power to an electrical load. The internal combustion engine, the alternator, and the controller are positioned within the cavity.
