Natural Gas Engines

WWI engines feature advanced engineering and reliable operation with emissions compliance to China III, China, IV or China V standards. The current engines are widely used in city bus, coach, and heavy-duty truck applications in China or exported to other regions globally. For future product development, Westport has advanced its injector technology to be adaptable to Weichai’s engine platforms and reduced the cost of key components.

WWI continues to experience strong growth in its initial natural gas engine business and anticipates numerous opportunities for an expanding partnership into new target markets.
