New natural gas school bus with ultra-low NOx is available in the U.S.

The bus, manufactured by Blue Bird, will feature an engine developed by ROUSH CleanTech that is 90% cleaner than the Environmental Protection Agency’s (EPA) most stringent heavy-duty engine standard of 0.2 grams per brake horsepower-hour (g/bhp-hr). It is also the first high-volume production CNG Type-C school bus engine certified to California Air Resources Board’s (CARB) optional low nitrogen oxide (NOx) emissions standard of 0.02 g/bhp-hr.

“Our customers want bus innovations that are environmentally friendly and allow them to access emissions-based grant funding, and the Blue Bird Vision CNG bus delivers,” said Phil Horlock, president and CEO of Blue Bird Corporation. “This is a huge step for Blue Bird and the school bus industry as we continue to be the first to bring the newest and cleanest engine technology into our lineup of buses.”

ROUSH CleanTech developed the technology using Ford’s 6.8L V10 engine. “After concentrating on reaching CARB’s optional low-NOx standards for our LPG engine, we bring our Roush engineering success to the CNG engines by reaching the same ultra-low emissions levels,” said Ryan Zic, vice president of school bus sales at ROUSH CleanTech.

This certification will help school districts obtain funding that supports NOx-reducing projects, such as the Volkswagen Environmental Mitigation Trust. More than 150 school districts operate about 5,500 CNG buses in the United States.

The new 0.02 ultra-low NOx option is now available to order for Blue Bird Vision CNG school buses.
