ROUSH CleanTech announced that, beginning mid-2023, all its Autgas engines will be certified to near-zero NOx emissions, as it has received California Air Resources Board (CARB) certification for 2023 model year Autogas engines at 0.02 grams per brake horsepower-hour. Previously available as an added-cost option, the ultra-low NOx emissions package is now standard on every LPG engine sold by ROUSH CleanTech.

The engines emit 90% less NOx emissions than allowed under 2023 regulations, and are 60% cleaner than California’s 2024 low-NOx standard, without compromising performance or efficiency.

“Customers can rest easy knowing that ROUSH CleanTech LPG engines provide ultra-low NOx emissions with no added cost today. And, we are well on our way to meeting California and EPA’s emissions standards for 2027 and beyond,” said Todd Mouw, executive vice president at ROUSH CleanTech.

Fleet operators purchasing 2023 models will have a greater chance of accessing state and federal funds that incentivise near zero emission vehicles, including the Infrastructure Investment and Jobs Act’s Clean School Bus Program and the Volkswagen Environmental Mitigation Trust settlement, among others.

ROUSH CleanTech first released low NOx engines in 2018. In 2021, it became the first manufacturer to receive CARB’s ultra-low 0.02 grams per brake horsepower-hour certification for Blue Bird school buses and commercial vehicles. “We didn’t wait for the regulation to go into law. We already achieved it,” commented Mouw.

The company’s newest technology and a growing renewable Autogas supply showcase how the fuel is no longer simply a “bridge” to help fleets reach U.S. emissions goals, but rather a destination transportation energy. Once fleets adopt bioLPG, they will operate with the same power and reliability as conventional LPG. This renewable fuel has an ultra-low carbon intensity, and at the point of combustion it is actually carbon neutral.
