Our flagship LNG fuel system optimal for heavy-duty vehicles

The heavy-duty freight sector has historically been difficult to decarbonize given the challenge of replacing diesel without compromising on vehicle performance and economics. There is now a solution with Westport™ High Pressure Direct Injection 2.0 ("Westport™ HPDI 2.0"), a fully OEM integrated system that enables heavy-duty trucks to operate on natural gas with reduced fuel costs, reduced CO2 emissions, and diesel-like performance.

Westport™ HPDI 2.0 features the only natural gas technology retaining the performance and efficiency of a diesel engine—critical for heavy duty engines in demanding commercial applications—while significantly reducing greenhouse gas ("GHG") emissions. Developed and validated to rigorous OEM standards, Westport™ HPDI 2.0 can be integrated into any engine and truck manufacturer’s offer.


Proven Performance


HPDI 2.0 offers the same power (>400hp), torque, engine braking and drivability as diesel, required to meet the harsh demands of heavy duty transport with no change in the driving experience.
High Efficiency


With optimized combustion, an HPDI 2.0 equipped engine can achieve diesel engine efficiency (within 1%) with inherently low engine-out unburnt methane emissions.
Low GHG Emissions


Designed to allow engines to meet the latest stringent emission regulations including Euro VI, HPDI 2.0 reduces GHGs by 20-100%[1] compared to the equivalent diesel engine on a well-to-wheel basis.
Fuel Cost Savings

Cost Savings

Fleets can realize significant cost savings when fueling with natural gas. The U.S. Energy Information Association ("EIA") predicts that the price of natural gas will remain below the price of petroleum diesel for decades.

What is HPDI 2.0?

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. HPDI 2.0 consists of a fully integrated “tank to tip” 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.

HPDI 2.0

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.

1 Low end of range is geologic natural gas; high end of range is renewable natural gas.

Market Opportunity

Providing GHG reductions of 20-100%[2] on a well-to-wheel basis while preserving the same performance as a diesel engine, Westport™ HPDI 2.0 is an integral part of the full spectrum of measures that the transportation sector will need to combat GHG emissions effectively.

A truck equipped with the Westport™ HPDI 2.0 system is an ideal solution for fleets wanting to reduce their fuel costs and offer decarbonized regional and long distance road transport solutions to their customers with no compromise on vehicle performance.

For end-users in the retail, food and beverage and additional sectors that have set ambitious internal sustainability plans with GHG/ CO2 emissions reduction objectives, Westport™ HPDI 2.0 is the best solution to achieve their targets for regional and long distance road transport operations without increasing transport costs.
