The technology enables a “downsized” natural gas solution that is cost-competitive while providing similar levels of power, torque, and fuel economy to a larger diesel engine. Westport ESI technology allows, for the first time, a spark-ignited natural gas engine to exceed the performance of a comparable state-of-the-art diesel engine.

To achieve its goals of lower emissions and better fuel economy, FPT significantly downsized the 0.9-liter liter TwinAir engine compared with its 1.2-liter liter engine, which has similar performance characteristics, making it 23% shorter and 10% lighter. The total weight of the system is minimized using durable low-weight materials.
