As shown by the regulatory agencies decisions to require all fuels in its HD-OBD certification, propane autogas and others like compressed natural gas are moving into the mainstream.

ROUSH CleanTech is the first propane autogas fuel system manufacturer to receive the Environmental Protection Agency’s and California Air Resources Board’s heavy duty-onboard diagnostics certification for all its engines. Until 2018 model year, alternative fuel vehicles had been exempt from this certification, but are now held to the same requirements as gasoline vehicles.

“Vehicles powered by a fuel other than gasoline or diesel should no longer be considered alternative,” said President Todd Mouw. “As shown by the regulatory agencies decisions to require all fuels in its HD-OBD certification, propane autogas and others like compressed natural gas are moving into the mainstream.”

This HD-OBD certification applies to all vehicles over 14,000 lbs GVWR. The onboard monitors will now track and report out the continuing compliance of the emissions performance of the vehicle, as they have since 2016 for gasoline vehicles. Passenger cars and light-duty vehicles have come equipped with onboard diagnostic systems since the 1990s.

All of ROUSH CleanTech’s propane autogas-fueled vehicles with Ford 6.8L 2V and 3V engines, including medium-duty fleet vehicles and school buses, are covered under the CARB HD-OBD certification. The 3V engine is also the first and only propane autogas engine available in class 4-7 vehicles certified to the optional low nitrogen oxide level of 0.05 g/bhp-hr.

“We continue to invest in innovative technology and the customer experience,” said Mouw. “Our customers deserve the best alternative-energy solutions we can bring to allow them to meet their economic and environmental sustainability goals.”
