CleanFUEL USA propane chassis attains certification

Posted on July 18, 2013

CleanFUEL USA, the nation’s first developer of liquid propane fuel injection systems, received Environmental Protection Agency (EPA) and California Air Resources Board (CARB) certification for the S2G chassis from Freightliner Custom Chassis Corp. (FCCC).

The engine and fuel system may now be purchased and used in all 50 states and Canada for up to 33,000 lbs. gross vehicle weight ratio (GVWR).

The chassis, which includes an eight-liter engine built by Powertrain Integration from a General Motors long block and a liquid propane injection (LPI) system manufactured by CleanFUEL USA, will be in full production by early September.

The S2G touts a carbon monoxide rating of 60% below and a nitrogen oxide rating of 20% below EPA set standards for heavy duty vehicles.

In addition to emissions certification, the S2G has undergone years of rigorous and comprehensive reliability testing, 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 joins other propane autogas vehicles CARB-certified with CleanFUEL USA's LPI system, including the GM 6.0-liter G4500.
