Westport awarded development contract to adapt and commercialize next gen LNG HPDI Fuel System for Euro 7 vehicle platform

Westport Fuel Systems has been awarded a development program by a global heavy truck manufacturer to adapt Westport’s Next Generation LNG HPDI fuel system to meet the Euro 7 emissions requirements for heavy-duty vehicle applications.

The value of the development program is estimated to be US$33 million and will be funded by the original equipment manufacturer (OEM). Work on the program is already underway with a targeted launch of the new LNG and liquified biomethane fueled product within a few years.


The Westport Next Generation LNG HPDI fuel system consists of on- and off-engine components: Fuel Rail, HPDI Fuel Injector, Gas Rail Inlet Injector & Gas Rail Vent Valve, Rail Pressure Regulator, HPDI Control Software, Integrated Gas Module, Cryogenic High-pressure Pump and Cryogenic Tank.

Westport’s Next Generation HPDI fuel system has been developed to meet the Euro 7 standards and will introduce the following new features:

  • Improved fuel pressure control, thereby improving fuel efficiency

  • Supporting higher pressure fuel supply systems to maximize engine performance and Brake Thermal Efficiency (BTE)

  • Improved reliability and durability

  • On Board Fuel Consumption Monitoring (OBFCM)

The program marks Westport’s next major engagement with the OEM to develop lower carbon solutions for heavy-duty trucking with the development of Westport’s Next Generation LNG HPDI fuel system encompassing on- and off-engine components. This new fuel system is an evolution of the existing HPDI LNG truck application from the OEM that is commercially available today and has been on the road for several years.

The Euro 7 standards are aimed at reducing air pollution from road transport, addressing pollutants such as nitrogen oxides (NOx) and particulate matter, by lowering emissions limits from new motor vehicles sold in the European Union, versus the standards currently set out in Euro VI. Final agreement on the new regulation remains outstanding, but for heavy-duty vehicles the European Commission’s proposal is to implement the new standards from mid-2027.
