Abstract
An engine driven generator has an inner rotor type generator with capacitor and AVR (Automatic Voltage Regulator) is selectively connected to a cam shaft, which rotates with half the speed of a crankshaft. An outer rotor type generator with inverter is selectively connected to a flywheel affixed to the crankshaft. Power generated by an engine at adequate rotating speed is fully transmitted to the generator and rotor speed of the generators satisfies requirement. A direction of rotation of crankshaft conforms with the typical standard of the industry relating to engines and generators.
Claims9
An engine generator comprising:
- a rotor and a stator;
- a single-cylinder, four-stroke cycle, spark ignition internal combustion engine having a crankshaft and a cam shaft which rotates with half speed of the crankshaft;
- wherein the rotor is selectively affixed to the cam shaft to be rotatable with the cam shaft and the stator is selectively affixed to an inner surface of a generator case affixed to an engine block, said engine generator being driven by said cam shaft.
