GAS TECHNOLOGY INSTITUTE LATE STAGE DEVELOPMENT, DEMONSTRATION, AND LAUNCH OF A CUMMINS WESTPORT ISX11.9G NATURAL GAS ENGINE

<< Return to Projects

The Gas Technology Institute and Cummins Westport, Inc. are in the process of demonstrating a unique, low-emission, high efficiency natural-gas engine 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. The engine will be demonstrated 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 and stands to achieve a 20 percent market penetration for this engine.

Grant Amount

$1,777,364

Match Funding

$3,622,636 from the project's participants.

Project Benefits

The new engine demonstrated in this project could improve fuel economy up to 10 percent from current spark-ignited natural-gas powered engines used in Class 8 trucks. The project has the potential of reducing 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.
