Development of the Ford QVM CNG Bi-Fuel 4.9L F-Series Pickup Truck 960850

A bi-fuel (Compressed Natural Gas [CNG] and gasoline) pickup truck has been developed using the Ford Alternative Fuel Qualified Vehicle Modifier (QVM) process. The base vehicle's 4.9L engine has been specially modified for improved durability on gaseous fuels. The base vehicle's configuration has been designed for conversion to bi-fuel CNG operation. A complete CNG fuel system has been designed and qualified, including fuel tanks, fuel system, and electrical interface. The completed vehicle has been safety and emission certified, demonstrating CARB Low Emission Vehicle (LEV) emissions in MY95. This paper details the design objectives, development process, CNG components, and integration of the two fuel systems.
