Cummins Westport Inc. said today that its new low-emissions LPG engine for mid-size truck and bus applications will be available for order May 15.

The 195-hp Cummins Westport B LPG Plus propane engine features the same advanced technologies found in the Cummins Westport C Gas Plus and B Gas Plus natural gas engines, the company said.

The engine will be available in new vehicles manufactured by ElDorado National, Elgin Sweeper Co., Ottawa Truck, and Freightliner Custom Chassis Corp.

"The positive feedback we've received on the performance of the B LPG Plus has confirmed our expectations for this engine," said Cummins Westport president Hugh Foden. "We look forward to expanding our business into this market area."

The B LPG Plus engine is certified to emit 12% less oxides of nitrogen and non-methane hydrocarbons and 70% less particulate matter than the coming 2004 ceilings established by EPA for heavy-duty trucks and buses.
