CleanFuel USA Reports U.S. EPA and CARB Approvals of FCCC Product,
Agency Nods Pave the Way for Bobtail Trucks and Type C School Buses

CleanFuel USA reports U.S. EPA and California Air Resources Board certification for the S2G chassis from Freightliner Custom Chassis Corp. The chassis features an 8.0-liter GM block engine, up to 350 horsepower, modified for dedicated liquid propane operation by Powertrain Integration with CleanFuel USA fuel system.

The certification paves the way for bobtail trucks – with propane delivery outfits high on the list as sales prospects – and propane fueled Saf-T-Liner C2 school buses by Thomas Built Buses – like FCCC a unit of Daimler.

Both are to commence production in September.

S2G chassis-based trucks are the only propane autogas vehicles on the market with a GVWR of 33,000 pounds, CleanFuel USA says. “The S2G greatly expands fleet offerings using this clean and abundant alternative fuel,” COO Wayne Moore says in the certification announcement.

Rigorous Testing and Validation

“The S2G has undergone years of rigorous and comprehensive reliability testing,” CleanFuel USA adds, “such as validation of the complete engine assembly (including the heavy duty accessory drives), engine durability tests, heavy-load testing and multiple rounds of high-altitude, cold and hot weather testing.”

The S2G certifications should mean more propane-powered Daimler Thomas Built  school buses, too.

“Our vehicles are held to an immensely high engineering standard, and the S2G is certainly no exception,” said Bryan Henke, FCCC’s manager of product marketing.

“The countless hours that the engineering teams put into testing and validating each and every component of the chassis, engine and fuel system is paying off as we are now able to offer a superb propane autogas product to the medium-duty market.”

‘Very Easy Trucks to Work On’

“They’re very easy trucks to work on,” Freeman Gas fleet manager Larry Shehan says in a CleanFuel USA video. “Everything is right there in front of you.”

Michigan’s New Eagle supported development of control technology for the Powertrain Integration engine. An S2G-based bobtail truck was shown at this year’s Work Truck Show in Indianapolis by PERC, the Propane Education & Research Council and STS, Signature Truck Systems, this mast March (F&F, March 8).

The factory-installed CleanFuel USA fuel system is supported through FCCC’s nationwide service network.

CNG Too from Thomas Built – Later

Propane autogas costs an average of 30 to 40% less than gasoline and about 50% less than diesel, CleanFuel USA notes.

Thomas Built is also preparing a compressed natural gas version of the Saf-T-Liner C2 school bus, waiting for the methane version of the 6.7-liter Cummins ISB to be released by Cummins Westport. The vehicle will be available in early 2015, says Thomas Built sales VP Ken Hedgecock.

“Alternative fuels is not a one-size-fits-all,” Hedgecock told F&F. “We want to make sure there are a variety of options based on customers’ needs.”
