Gas Technology Institute Grant For the Late Stage Development, Demonstration, and Product Launch of Cummins Westport ISX11.9G Natural Gas Engine Project

The Gas Technology Institute and Cummins Westport, Inc. will demonstrate a unique, low-emission, high efficiency natural-gas engine designed for regional hauling and heavy vocational truck applications. The advanced ISX11.9 G natural gas engine fills an important market gap – there is currently no such engine option available for long distance class 8 trucking.

Swift Transportation will demonstrate one of the engines in a highway tractor for 12 months, logging approximately 2,000 miles per month while hauling loads up to 80,000 lbs. gross vehicle weight.

The project will complete all necessary development, testing, certifying, and demonstration needed to commercialize the ISX11.9 G natural gas engine, with a goal of achieving 20 percent market penetration for this class of engine.

Grant Amount

$1,777,364

Match Funding

$3,600,000 from the project’s participants.

Project Participants

Gas Technology Institute (GTI) is an Illinois-based, not-for-profit Research and Development organization for the energy industry. For this project GTI will provide overall project leadership and management.

Cummins Westport Inc.(CWI) is a joint venture company of Cummins Inc. and Westport Innovations Inc. which was formed in 2001. Indiana-based CWI will be the technical lead in the project, providing engine development, engineering, fabrication, testing, and performance verification.

Swift Transportation is one of the largest on-highway freight carriers in the world. Swift Transportation will function as a demonstration partner and will demonstrate one engine in a highway tractor for 12 months.

Cummins Cal-Pacific, CWI’s California distributor, will assist and support the vehicle testing and data collection process here in the state.

Project Benefits

The new engine should improve fuel economy up to 10 percent from current spark-ignited natural-gas powered engines used in Class 8 trucks. The project will reduce greenhouse gas emissions by 20 to 25 percent and fuel use by at least 20 percent or the equivalent of 10,770 diesel gallons per truck annually.
