Tri-fuel electric power generator

1. An electricity generator comprising:

a generator section which is a complete standalone electricity generator designed to operate on a hydrocarbon fuel, the generator section including:

a rotations per minute (RPM) control unit;

an internal combustion engine which has a crankshaft;

an electromagnetic conversion component which converts rotational motion of the crankshaft into electricity; and

a crankshaft sensor which senses rotational speed of the crankshaft thereby creating an RPM control signal, the RPM control signal being provided to the RPM control unit which controls the rotational speed of the crankshaft; and

a fuel conversion section which adapts the generator section to operate on alternative fuels that are different than a designed fuel of the generator section, the fuel conversion section including a first fuel source and a second fuel source, the first fuel source providing a methanol-containing fuel and the second fuel source providing liquefied petroleum gas (LPG) providing or flare gas.

2. The electricity generator of claim 1 wherein the hydrocarbon fuel is methane or propane.

3. The electricity generator of claim 1 wherein generator section is of a conventional electromagnetic type which converts the input mechanical energy from rotation of crankshaft into a generally sinusoidal electric current or voltage.

4. The electricity generator of claim 1 wherein the electromagnetic conversion component is of a dynamo or alternator design.

5. The electricity generator of claim 1 further comprising a fuel selector switch to select a fuel for operation of internal combustion engine.

6. The electricity generator of claim 5 wherein the generator section includes a manifold and the fuel conversion section includes one or more fuel injectors.

7. The electricity generator of claim 6 wherein if methanol is selected, the methanol is fed to the fuel injectors and then to the manifold.

8. The electricity generator of claim 6 wherein if methanol is selected, the methanol is directly injected into engine cylinders.

9. The electricity generator of claim 6 wherein if LPG or flare gas is selected, the fuel is provided directly to the manifold.

10. The electricity generator of claim 6 wherein the fuel conversion section further includes an engine control unit which receives the RPM control signal from the generator section while sending an ignition control signal to ignition coils.

11. The electricity generator of claim 10 wherein the engine control unit receives signals for manifold air, manifold air temperature as well as accessing a lambda table, EV table, and ignition advance table all of which are used for engine control.

12. The electricity generator of claim 10 wherein the engine control unit controls engine speed via throttle.

13. The electricity generator of claim 10 wherein spark ignition timing is managed by the engine control unit based on crank position signal from generator section.

14. The electricity generator of claim 10 wherein a spark advance table, a lambda table, which are functions of manifold air pressure (MAP), manifold air temperature (MAT), engine speeds, and load, are calibrated and then saved in the engine control unit.

15. The electricity generator of claim 10 wherein the fuel conversion section further includes at least an oxygen sensor.

16. The electricity generator of claim 15 wherein remaining oxygen in an exhaust is detected by the oxygen sensor resulting in changes in engine management since different fuels have different stoichiometric air fuel ratios.

17. The electricity generator of claim 10 further comprising a catalytic converter.
