Appl. No.:
09/993651

Abstract:
Through a series of valves that are preset to control the fuel flow, volume low and high for starting, idling and high maximum RPM engine running. The fuel delivery system is coupled to fuels of choice. Fuels consisting of the following: Liquefied petroleum gas (LPG), compressed natural gas (CNG), liquefied natural gas (LNG), and biogas. It can also be used with a combination of gases and liquefied hydrocarbon fuels. The Fuel Delivery Valving and Hose System is connected to the fuel source with a hose slid over a male barb and clamped in place. The fuel source can be a fuel tank, a fuel tank with a regulator or directly to a fuel line. The hose from the fuel source is connected to the main shut off valve on the inflow side. A piece of hose is connected to the main shut off valve on the outflow side to an inflow tee, the tee allows the fuel to go in two directions simultaneously or separately. The hose connected to the secondary part of the tee goes to the low RPM valve. This valve outflow controls the low volume of fuel for starting and idling. There is a piece of hose connected to tee outflow side to the high RPM run valve inflow. This high rpm run valve is kept shut until the engine is started, then opened to allow a controlled higher volume of fuel to pass through. A piece of hose is connected to the outflow of the high RPM run valve to a second tee. The low RPM run valve is connected to this same second tee by hose. This creates a loop. When the high RPM run valve is off it directs the fuel through the low RPM run valve for starting and idling. The second tee is connected to the high RPM valve by hose. This valve is preset to insure that the maximum controlled amount of fuel is delivered to the injector. The high RPM valve outflow is connected to a hose that is connected to an injector. This injector is tapped directly into a carburetor insulator or intake manifold.
