Westport Fuel Systems Inc. engineers, manufactures, and supplies advanced alternative fuel systems and components focused on decarbonizing hard-to-abate transport applications. The company's core technology is its High-Pressure Direct Injection (HPDI) fuel system, which enables heavy-duty engines to operate on clean gaseous fuels such as liquefied natural gas (LNG), compressed natural gas (CNG), liquefied petroleum gas (LPG), and hydrogen. Westport provides comprehensive solutions, including on-engine systems and off-engine high-pressure controls and components, primarily for Original Equipment Manufacturers (OEMs) to facilitate emissions reduction.
