California certifies next-gen LPG school bus engines to lowest NOx in market

ROUSH CleanTech has become the first original equipment manufacturer to receive California Air Resources Board’s (CARB) 0.02 grams per brake horsepower-hour certification for 2022 model year vehicles. The optional ultra-low CARB certification is 90% cleaner than current emissions standards for nitrogen oxides (NOx). The new engine certification covers ROUSH CleanTech Gen 5 Autogas engines for Blue Bird school buses.

“Blue Bird is the leader in clean emissions school buses with over a decade of selling experience, and more than 20,000 clean and cost-reducing LPG school buses on the road,” said Matthew Stevenson, president and CEO of Blue Bird Corporation. “Equipping our buses with the lowest NOx LPG engine is great news for the environment, our customers and our children.”

“Since the introduction of our Ford 7.3L V8 LPG engine in 2020, our team has worked tirelessly to gain this emissions certification,” said Todd Mouw, president of ROUSH CleanTech. “We remain committed to providing cost-efficient, advanced vehicle solutions for the school bus market that reduce environmental impact.”

In addition to being 90% cleaner than national emissions requirements, ROUSH’s next-gen Autogas engines achieve 2027 proposed standards on NOx.

Blue Bird Autogas school buses equipped with the ultra-low NOx engines will provide school districts and school bus contractors multiple advantages in seeking funding from the new Infrastructure Investment and Jobs Act’s Clean School Bus Programme.

The provision awards $2.5 billion for the purchase of low- and zero-emission school buses, including LPG which is identified in the legislation as an emerging alternative fuel. Funding is slated to be released beginning in 2022 and continuing through 2026, with project implementation as soon as next year. For more information, please visit this link
