GEORGETOWN, Texas — The EPA has certified CleanFUEL USA’s liquid propane engine built on a General Motors 6.0L chassis.

CleanFUEL’s advanced propane engine utilizes the patented Icom JTG Technology and System manufactured by Icom North America and offers the same horsepower, torque and performance as gasoline-powered engines while producing 87 percent less hydrocarbons and 50 percent less toxins than gasoline, the company said.

The engine also features CleanFUEL’s liquid propane injection (LPI) system to provide a high-performance, fuel-efficient alternative to gasoline and diesel engines. CleanFUEL’s system reportedly performed 25 percent better than comparable gasoline and diesel engines tested against current EPA standards, also reporting a zero particulate matter emissions rate. 

Type A school bus manufacturer Collins Bus Corp. will display its propane-powered bus featuring CleanFUEL’s EPA-certified 6.0L LPI system April 9-12 at the NPGA Southeastern Convention & International Propane Expo in Atlanta.  

“It’s essential to deliver innovative products that meet our customers’ demand for clean-fuel alternative vehicles,” said Kent Tyler, president of Collins Bus Corp. “We are excited to partner with leaders in the propane industry, such as CleanFUEL USA and the Propane Education & Research Council to expand fleet options for school districts evaluating greener modes of transportation to take advantage of federal tax incentives.”

CleanFUEL’s liquid propane engine is now undergoing testing by the California Air Resources Board. The company expects it to be fully certified and commercially available by this summer.
