Propane Vehicle Conversions
Vehicle conversions provide alternative fuel options for fleets. Certain light-duty propane vehicles can be ordered from a dealer. A qualified system retrofitter (QSR) can also reliably convert certain in-service light-, medium-, or heavy-duty vehicles for propane operation. Conversion systems must be certified as compliant in accordance with U.S. Environmental Protection Agency (EPA) regulations. EPA lists these systems as Certified Clean Alternative Fuel Conversion Systems.
Propane vehicle conversions in the United States require U.S. Environmental Protection Agency (EPA) certification and a QSR should perform the installation. For more information about regulations, codes, and standards, see the Vehicle Conversions page.
Under a Clean Cities American Recovery and Reinvestment Act Project Award, the Railroad Commission of Texas developed a four-part series on converting vehicles to propane. The materials provide technical training on retrofitting, servicing, and fueling propane-powered vehicles. They also cover troubleshooting and diagnostics for IMPCO Technologies Inc., CleanFuel USA, Roush CleanTech, and Prins Alternative Fuel Systems.
The upfront costs to convert fleet vehicles to propane can be offset by lower operating and maintenance costs over the lifespan of the vehicles. Propane can be an attractive option when the overall cost per mile to operate a propane vehicle is taken into consideration.
