Abstract

A power generation system is provided including a power boost regulator operative to provide load matched voltage operation of an AC power source.

Claims (28)

1. An engine assembly including:

an engine including a cylinder head, a crankcase, and a crankshaft positioned in the crankcase; and

an alternating current (AC) power generator assembly coupled to the crankcase and driven by the crankshaft, the AC power generator assembly including

a housing,

a magneto assembly including a stator and a rotor,

a flywheel coupled to the magneto assembly and positioned in the housing, and

a shroud member at least partially disposed inside the housing, the shroud member positioned to block air flow between the housing and the flywheel.

2. The engine assembly of claim 1 , a wall of the crankcase including a plurality of apertures configured to direct air from outside the engine to the stator of the magneto.

3. The engine assembly of claim 1 , the flywheel including a plurality of spaced apertures, the shroud member directing air flow from the stator through the spaced apertures of the flywheel.

4. The engine assembly of claim 1 , wherein the shroud member includes a circumferential wall at least partially disposed inside the housing and extending between the housing and the flywheel.

5. The engine assembly of claim 1 , wherein the shroud member is coupled to the housing between the housing and the crankcase.

6. The engine assembly of claim 1 , wherein the shroud member is integrated with the flywheel.

7. The engine assembly of claim 1 , wherein the housing includes a plurality of apertures extending through an outer wall of the housing, and the plurality of apertures are configured to direct air flow from the flywheel to the outside of the engine.

8. The engine assembly of claim 7 , wherein the AC power generator assembly further includes a recoil starter positioned between the flywheel and the housing, and the recoil starter includes a plurality of apertures configured to direct the air flow from the flywheel to the apertures of the housing.

9. An engine assembly including:

an engine including a cylinder head, a crankcase, and a crankshaft positioned in the crankcase, the crankcase including at least one opening; and

an alternating current (AC) power generator assembly coupled to the crankcase and driven by the crankshaft, the AC power generator assembly including

a housing,

a magneto assembly including a stator and a rotor positioned in the housing,

a flywheel coupled to the magneto assembly and positioned in the housing, and

a shroud member positioned to cause air received through the at least one opening in the crankcase into an interior of the magneto assembly.

10. An engine assembly including:

an engine including a cylinder head, a crankcase, and a crankshaft positioned in the crankcase; and

an alternating current (AC) power generator assembly coupled to the crankcase and driven by the crankshaft, the AC power generator assembly including

a housing,

a magneto assembly including a stator and a rotor,

a flywheel coupled to the magneto assembly, and

a shroud member coupled to the housing and positioned to block air flow between the housing and the flywheel, the shroud positioned so that an airflow passes through an interior of the magneto assembly to the flywheel and subsequently out of openings in the housing.
