Westport to develop next-gen
LNG fuel system for truck OEM
Westport Fuel Systems announced that it has been awarded
a development program by a global heavy-truck manufacturer
to adapt its LNG (liquified natural gas) HPDI fuel system
to meet Euro 7 emissions requirements for heavy-duty
vehicle applications.
" This new program exemplifies our longstanding relationship
with the OEM, emphasizing our shared vision of creating
sustainable transport solutions around the world, " said
Anders Johansson, VP of heavy-duty OEM for Westport Fuel
Systems. " Our LNG HPDI fuel system enables long-haul trucks
to significantly reduce CO2
emissions now while fully meeting
a fleet's performance demands for payload, performance and
durability, as well as stringent Euro 7 emission regulations. "
According to Westport, the value of the program is estimated
to total $33 million USD and will be funded by its OEM
partner. Westport also states that work on the program has
already begun, and the company has targeted a launch date
" within the next few years. "
Gassed up
Westport's HPDI fuel system consists of a fully integrated " tank
to tip " solution, with a cryogenic tank and integral high-pressure
LNG pump mounted on the chassis of the truck. The system is
plumbed to the engine where fuel pressure is regulated before
being supplied to the injectors via high-pressure fuel rails.
The system also features a patented injector with a dual concentric
needle design which, according to Westport, allows for
small quantities of pilot fuel and large quantities of natural gas to
be delivered at high pressure to the combustion chamber. The
natural gas is injected at the end of the compression stroke. The
system was developed specifically to meet the Euro 7 standards,
which will be implemented from mid-2027 onwards.
