VANCOUVER, B.C. — Westport Innovations has introduced its new low-emissions liquid petroleum gas (LPG) engine for mid-size trucks.

Customers will be able to order the 195-horsepower Cummins Westport B LPG Plus propane engine as of May 15. The new engine incorporates much of the same technology as the B Gas Plus natural gas engines designed by Westport.

Drive-by-wire technology, advanced electronic controls, improved sensors, knock detection and wider range fuel capability are some of the features the company says its incorporated into its new engine.

“The positive feedback we’ve received on the performance of the B LPG Plus has confirmed our expectations for this engine. There is a significant opportunity for this engine with mid-size truck and bus customers who are looking for a robust and reliable LPG engine. We’re confident our proven Plus technology delivers real customer value, and we look forward to expanding our business into this market
area,” says Hugh Foden, president of Cummins Westport.

The LPG Plus engine emits 12 per cent less nitrogen and non-methane hydrocarbons and 70 per cent less particulate matter than the upcoming 2004 Environmental Protection Agency standards, the company says. The engine will be available throughout the Cummins network of dealers. More information is also available at
