Abstract
An air bleed vapor system is provided having a primary vapor manifold connected to a fuel line take-off for providing a source of liquid fuel to the system. A vapor control module incorporates a precision needle valve for allowing metering of extremely small flowrates of liquid fuel into the vapor manifold. A pressure line is inserted into the PCV intake of a vehicle, and a secondary vaporization chamber is in fluid communication with the pressure line and the vapor control module, and provides an oxygen intake chamber into which an air-fuel mixture can be held at the pressure of the vehicle's crankcase ventilation system. Finally, a delivery vaporization conduit in the form of a linearly elongated chamber is in fluid communication with the PCV manifold of the vehicle.
Claims7
An air bleed vapor system for use with a vehicles positive crankcase ventilation (PCV) system comprising:
- a primary vaporization manifold for mixing air and fuel;
- fuel supply means for delivering liquid fuel to said primary vaporization manifold;
- air supply means for delivering pressurized air from a vehicle's PCV system to said primary vaporization manifold;
- and
- air-fuel delivery means for delivering said mixed air and fuel from said primary vaporization manifold to a vehicle's PCV system;
- wherein said delivered mixed air and fuel has sufficient time, distance, and thermal transfer to fully vaporize any fuel delivered into the system such that the air entering the vehicle's PCV manifold contains a quantity of completely vaporized fuel;
- and
- a secondary vaporization chamber in fluid communication with said primary vaporization manifold for providing an oxygen intake chamber into which an air-fuel mixture can be held at a pressure of the vehicle's crankcase ventilation system.
