Westport Fuel Systems Inc. displayed its HPDI™ fuel system on commercial vehicles equipped with its commercially available LNG and bio-LNG and its hydrogen capable and proven variant H₂ HPDI. The vehicles were presented at the Advanced Clean Transportation (ACT) Expo 2023 in Anaheim, California.
Alternative fuels used in internal combustion (IC) engines are necessary to achieve a zero-emissions transition in the next two decades. The HPDI fuel system enables existing IC engine architecture to operate with a variety of alternative fuels, including natural gas, biomethane, syngas and hydrogen, as increasingly popular alternatives to diesel fueled engines.
Equipping a diesel cycle engine with the HPDI fuel system allows OEMs to leverage existing vehicle and manufacturing infrastructures, engineering competencies and resources, while improving performance and emissions. An HPDI fuel system-equipped IC engine fueled with H₂ achieves near zero CO₂ emissions, while delivering peak performance spanning power, efficiency, and torque.
“With impending regulations and the overall desire for cleaner transportation, fleets need solutions that are not only viable for their operation but are technically available, affordable, and consistent with market realities,” said David M. Johnson, CEO of Westport Fuel Systems. “Our HPDI fuel system is a practical solution at the OEM level supported by market-available fuels when a vehicle hits the road. This translates to a realistic, immediate path forward for fleets to achieve their decarbonization goals.”
Westport’s HPDI fuel system solution significantly reduces capital investments by utilizing current powertrain, driveline, and compression ignition engine platforms, as well as preserves crucial engineering expertise and current supply chains, all resulting in expedited time to market and a low-cost option to CO₂ compliance in long-haul trucking. It is currently collaborating with three global commercial transportation OEMs to evaluate the performance, efficiency and emissions of the OEMs’ engines equipped with Westport’s H₂ HPDI fuel system, which was first introduced in 2022.
Westport also continues to see growth across its hydrogen fuel component business as it continues to supply and meet increasing demand for complete fuel systems for hydrogen fuel cell and hydrogen internal combustion engine applications; from high-pressure tank valves to low-pressure electronic fuel control.
