Cummins Westport engines are 100% natural gas engines for use in on-road automotive vehicle applications, such as urban transit, shuttle and school bus, and medium and heavy duty trucks. Cummins Westport engines are not conversions, or retrofits. We do not offer products to convert a diesel engine to run on natural gas.
