Blue Bird first to offer ultra-low NOx, type-C school bus fueled by CNG
 

May 8, 2019. School districts and transportation contractors can now purchase buses fueled by compressed natural gas (CNG) that are 90 percent cleaner than the national emissions standard, opening more opportunities for funding that supports reduced emissions.

   “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. It’s the first high-volume production CNG Type-C school bus engine certified to California Air Resources Board’s optional low nitrogen oxide emissions standard of 0.02 grams per brake horsepower-hour (g/bhp-hr).

   “After concentrating on reaching CARB’s optional low-NOx standards for our propane engine, we bring our Roush engineering success to the CNG engines by reaching the same ultra-low emissions levels,” said Ryan Zic, director of school bus sales at ROUSH CleanTech.

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