Vapor fueled engine
A fuel supply assembly is provided that may allow for use of vaporized fuel to power an engine and enhance fuel efficiency. The fuel supply assembly may include a vaporizing tank, a heating source, a temperature control and a monitoring and control system configured to control intermixing of ambient air and vaporized gasoline to maintain a desired hydrocarbon level in an exhaust.
1. A fuel supply assembly comprising:
a vaporization tank to vaporize an amount of fuel;
a heating element coupled to the vaporization tank and adapted to vaporize the amount of fuel;
an air conduit to supply an amount of air to mix with the vaporized amount of fuel; and
a controller adapted to control a mixture of the vaporized amount of fuel and the amount of air to maintain a desired carbon level present in an amount of combustion exhaust.
2. The fuel supply assembly of claim 1 further comprising a temperature sensor coupled to the vaporization tank and adapted to monitor the temperature of the amount of fuel.
3. The fuel supply assembly of claim 1 further comprising an exhaust sensor adapted to monitor the combustion exhaust for the presence of carbon content.
4. The fuel supply assembly of claim 3 wherein the exhaust sensor monitors the combustion exhaust for O 2 emissions and determines the presence of carbon content based on the O 2 emissions.
5. The fuel supply assembly of claim 1 further comprising a fuel controller for selectively providing the vaporized amount of fuel and/or liquid fuel to a combustion chamber.
6. The fuel supply assembly of claim 5 wherein the liquid fuel is a residual fuel, the residual fuel consisting of a portion of the amount of fuel.
7. The fuel supply assembly of claim 1 further including, a plurality of valves, the plurality of valves controlled by the controller to maintain the mixture of air and the vaporized amount of fuel.
8. The fuel supply assembly of claim 1 wherein, the air conduit supplies the amount of air into the vaporization tank to mix with the vaporized amount of fuel.
9. A method comprising:
supplying an amount of fuel into a vaporization tank;
increasing the temperature of the amount of fuel in the vaporization tank to vaporize the amount of fuel;
supplying an amount of air through an air conduit;
mixing the amount of air and the vaporized amount of fuel; and
controlling the mixing of the amount of air and the vaporized amount of fuel to maintain a desired carbon level in an amount of combustion exhaust.
10. The method of claim 9 further comprising conveying the intermixed amount of air and vaporized amount of fuel to a combustion engine.
11. The method of claim 9 wherein, the controlling the intermixing of the air and the vaporized amount of fuel to maintain a desired carbon level in the amount of combustion exhaust includes using a plurality of valves to control the amount of air that is inducted into the vaporization tank.
12. The method of claim 9 further comprising, continuously monitoring the combustion exhaust for the presence of carbon content.
13. The method of claim 12 wherein, the monitoring further comprises monitoring O 2 emissions and determining the presence of carbon content based on the O 2 emissions.
14. The method of claim 9 farther comprising, purging the vaporization tank periodically.
15. The method of claim 9 wherein the inducting the amount of air through the air conduit to mix with the vaporized amount of fuel comprises inducting the amount of air through the air conduit and into the vaporization tank to mix with the vaporized amount of fuel.
16. The method of claim 9 farther comprising, increasing the temperature of the vaporized amount of fuel and the amount of air.
