Super-Gas™ Vehicle Conversion 2001-01-2473

The composite fuel, trademarked as “Super-Gas™”, a combination of Propane (LPG) and Compressed Natural Gas (CNG), is stored in liquid form at relatively low pressures (1460 psig) as compared to traditional CNG systems. Vehicle conversion systems for this fuel system utilize many of the same components (conversion kit) as commercially available CNG systems.
Currently, three vehicles have been converted to operate in Super-Gas™ utilizing CNG conversion kits from three different after-market manufacturers. Driving testing has shown almost a two times increase in range compared to CNG for the same tank volume. Furthermore, RG-240 emission tests were successfully passed when the appropriate vehicle conversion is used. Finally, vehicle performance improves greatly even under heavy loads.
Although the cost of the Super-Gas™ conversion kit is similar to the CNG's, the benefits of extended range and vehicle performance justify the investment.
