At the heart of the HPDI fuel system is an injector with a dual concentric needle design.

Volvo and Westport Fuel Systems have partnered to jointly promote and develop Westport's High Pressure Direct Injection (HPDI) technology. In doing so, the companies intend to "mov[e] forward affordable, sustainable transportation solutions using the internal combustion engine operating on renewable fuels now and hydrogen in the future."

The HPDI system has been deployed in thousands of Volvo trucks across Europe, underscoring its effectiveness in achieving carbon neutrality, according to the companies.

Since the commercial release of HPDI in 2018, fleets have collectively avoided hundreds of thousands of tons of CO2 emissions annually.

“We believe HPDI-powered internal combustion engines, running on hydrogen and renewable fuels, play a crucial role in global decarbonization efforts in commercial transportation," said Lars Stenqvist, CTO Volvo, in a statement. "The joint venture enables us to combine this fuel system with our strategic expertise to guide OEMs and fleets as they navigate the energy transition.”

“This is a momentous occasion for Westport and the HPDI technology," said Scott Baker, VP, product development and technology officer of the joint venture, in a statement. "The alliance between our two companies affirms our steadfast commitment to drive decarbonization in the heavy-duty sector utilizing alternative fuels while still providing the efficiency, power and durability that comes with diesel cycle engines."
