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.
