Earlier this month, the EPA and CARB certified the Cummins ISB 6.7 L as the first diesel school bus engine to meet Clean Air Act requirements of 0.20 g of oxides of nitrogen (NOx) per brake horsepower hour without the use of emissions credits. This week, Blue Bird tipped its hat in recognition of the achievement.
“This accomplishment by our diesel engine partner is excellent news for our school bus customers and fully supports our leadership position in offering green solutions to the school bus industry,” said Phil Horlock, president and CEO of Blue Bird Corporation, which has produced more than 10,000 SCR-equipped school buses. “Blue Bird is focused on providing customers with the best in affordable, green technology and Cummins’ SCR technology gives our customers the ability to achieve near-zero emissions.”
The company said Coweta County Schools in Newnan, Ga., about 40 miles southwest of Atlanta, operates 2011 and 2012 model-year powered by the Cummins ISB and reports that maintenance service has been minimal.
“Our Blue Bird buses with SCR technology provide us with seamless operation. System maintenance is minimal with upkeep performed during regular scheduled maintenance intervals,” said Keith McCullough, shop foreman at Coweta County Schools. “We have zero complaints with our Blue Bird buses.”
Earlier this month, Tom Hodek, GM of Cummins’ Bus Business, said the certification reaffirmed the company’s confidence in utilizing SCR technology to meet emissions standards.
The certified Cummins ISB 6.7L is equipped in all Blue Bird Vision and All American school buses.
