CE Series School Bus to Have 8.8-Liter PSI Engine,
Oklahoma-Built Buses for the 2015-2016 School Year
Navistar International’s IC Bus unit is promoting its CE Series school buses, which can handle up to 78 passengers, with the 8.8-liter dedicated propane autogas engine from Power Solutions International for the 2015 model year.
“Purpose-built for the school bus industry, the CE Series with PSI propane engine is designed to provide diesel-like performance with higher torque at lower engine speeds,” IC says.
“Our customers asked for a better propane fuel choice for the market and we answered,” IC Bus president John McKinney says in a release.
More Power = Less Strain
“Our IC Bus CE Series with PSI’s 8.8-liter LP engine will be the first school bus specifically engineered to run on propane without sacrificing power, performance or durability,” McKinney said.
With a torque rating of 565 foot pounds at 1500 rpm, the bus will have better acceleration and hill climbing capability, with less noise and vibration. “Minimal revving reduces engine wear, oil usage and maintenance, while increasing durability and efficiency,” IC says.
“Until now, the propane vehicle market had been supported by underpowered engines that are required to run at high-speeds to get the required power,” PSI chairman and CEO Gary Winemaster says in the IC release.
Ready for the 2015-2016 School Year
“The PSI 8.8-liter engine is an economic, low-speed solution that boasts diesel-like performance, high durability, reduced noise and overall wear with all the benefits of alternative fuels,” Winemaster said.
PSI reported U.S. EPA certification of the 8.8-liter engine earlier this past summer (F&F, July 15).
IC Bus said Tuesday that it will build the propane-powered CE Series buses at its assembly plant in Tulsa, Okla. Deliveries will begin in summer 2015 and the vehicles are to go into service for the start of the 2015/2016 school year.
Navistar reported late last month that Trish Reed has been named VP and general manager of IC Bus, bringing more than 24 years of industry experience including VP of business operations at Navistar Financial Corp and specialty vehicles GM at Uptime Parts.
