Westport HPDI™ is a complete system offering OEMs the flexibility to differentiate their natural gas product lines easily while also maintaining maximum commonality with conventional engines and powertrain lines.
HPDI™ consists of a fully integrated on engine and off engine fuel system components and electronic control solution, with a cryogenic tank and integral high pressure liquefied natural gas (“LNG”) pump mounted on the chassis of the truck and plumbed to the engine where fuel pressure is regulated before being supplied to the injectors via high pressure fuel rails.
Westport™ HPDI™ 2.0 is a complete system offering OEMs the flexibility to differentiate their natural gas product lines easily while also maintaining maximum commonality with their conventional diesel fueled products.
At the heart of the engine is a revolutionary patented injector with a dual concentric needle design. It allows for small quantities of diesel 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.
