ROUSH CleanTech (Livonia, Mich.) has received the Environmental Protection Agency’s and the California Air Resources Board’s heavy duty-onboard diagnostics (HD-OBD) certification for all its engines. Until the 2018 model year, alternative fuel vehicles had been exempt from the 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 ROUSH CleanTech president Todd Mouw. “As shown by the regulatory agencies’ decisions to require all fuels [be included] in its HD-OBD certification, propane autogas and others like compressed natural gas are moving into the mainstream.” ROUSH explains that the HD-OBD certification applies to all vehicles with a gross vehicle weight rating (GVWR) of more than 14,000 lb.

“Vehicles powered by a fuel other than gasoline or diesel should no longer be considered alternative,” said ROUSH CleanTech president Todd Mouw. “As shown by the regulatory agencies’ decisions to require all fuels [be included] in its HD-OBD certification, propane autogas and others like compressed natural gas are moving into the mainstream.”
ROUSH explains that the HD-OBD certification applies to all vehicles with a gross vehicle weight rating (GVWR) of more than 14,000 lb. Onboard monitors will now track and report 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.
