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. CConversion systems must be certified as compliant with 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 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, 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 fueling infrastructure and volume fuel discounts are available.
