Westport Fuel Systems Inc. Press Release and Form 6-K Filing

Westport Fuel Systems Inc. has filed a Form 6-K report, incorporating a press release dated April 30, 2026. The press release announces the North American demonstration of Westport's high-pressure CNG fuel storage system combined with Cespira's on-engine HPDI™ fuel system at ACT Expo 2026. This technology aims to provide heavy-duty trucks with diesel performance and efficiency using compressed natural gas (CNG), a more readily available alternative to liquefied natural gas (LNG) in North America. The system is designed for diesel combustion engines and offers lower emissions, diesel-cycle performance, and comparable maintenance schedules to diesel engines. Westport also highlights the HPDI system's adaptability to hydrogen, presenting a potential pathway for hydrogen adoption in heavy-duty transportation. The company believes this technology will enable fleets to reduce emissions and operating costs while facilitating a transition to lower-carbon fuels.
