Abstract
A generator includes an elongated tubular frame, an internal combustion engine attached to the elongated tubular frame, the engine including an engine block including a cylinder and a crankshaft configured to rotate about a crankshaft axis. The generator further includes a fuel tank attached to the elongated tubular frame. The elongated tubular frame is configured to simultaneously support the internal combustion engine and the fuel tank.
Claims19
An inverter generator comprising:
- an elongated tubular frame;
- an internal combustion engine attached to the elongated tubular frame;
- an alternator attached to the tubular frame, connected to the internal combustion engine, and configured to produce electricity:
- a fuel tank including a flange, wherein the fuel tank is attached to the elongated tubular frame by the flange:
- a housing attached to the tubular frame, wherein the elongated tubular frame is hidden within the housing:
- and
- wherein the elongated tubular frame is configured to simultaneously support the internal combustion engine, the alternator, and the fuel tank such that the housing can be removed without damaging the structural integrity of the inverter generator;
- an electrical outlet;
- and
- a controller comprising an inverter, the inverter configured to receive electrical power from the alternator and provide an electrical output to the electrical outlet;
- wherein the controller is configured to temporarily suspend the electrical output to the electrical outlet at a first speed of the engine and turns on the electrical output after a second speed of the engine is attained;
- wherein the second speed is more than the first speed.

An inverter generator comprising:
- an internal combustion engine comprising:
- an engine block including a cylinder;
- an alternator connected to the internal combustion engine;
- a crankshaft configured to rotate about a crankshaft axis;
- a muffler including a muffler pipe extending along a muffler pipe axis and terminating at a muffler exhaust;
- a first heat shield and a second heat shield each configured to create a barrier between the engine and the muffler, the first and the second heat shields attached to the elongated tubular frame, wherein the first and the second heat shields partially surrounds the muffler, and wherein the first heat shield includes a first gap between the first heat shield and the muffler exhaust and a second gap between the first heat shield and the cylinder:
- wherein the muffler pipe axis is substantially perpendicular to the crankshaft axis;
- an electrical outlet;
- and
- a controller comprising an inverter, the inverter configured to receive electrical power from the alternator and provide an electrical output to the electrical outlet;
- wherein the controller is configured to temporarily suspend the electrical output to the electrical outlet at a first speed of the engine and turns on the electrical output after a second speed of the engine is attained;
- wherein the second speed is more than the first speed.
9 more elements
An inverter generator comprising:

- an electrical outlet:
- and
- a controller comprising an inverter, the inverter configured to receive electrical power from the alternator and provide an electrical output to the electrical outlet;
- wherein the controller is configured to temporarily suspend the electrical output to the electrical outlet at a first speed of the engine and turns on the electrical output after a second speed is attained of the engine;
- and
- wherein the second speed is more than the first speed.
