What is HPDI?
High Pressure Direct Injection is a fuel system used to reduce CO2 in long-haul trucking and other high-load and off-road applications. HPDI technology replaces greenhouse gas-emitting fuels, like diesel, with carbon-neutral or zero-carbon fuels like biogas or hydrogen. HPDI is affordable, durable, efficient, and maintains (or even improves) the performance characteristics that have come to be associated with diesel.
H2 HPDI
- 20% more power, 15% more torque
- Near Zero CO2 emissions
- Lowest cost to CO2 compliance
- Preserve existing engine manufacturing
LNG HPDI
- Same torque, efficiency, and reliability as diesel engines
- 20% CO2 reduction tailpipe
- 100% CO2 reduction with Bio-LNG
- No change to vehicle or engine architecture
What applications use HPDI?
HPDI technology is highly versatile and can be used with several alternative fuel sources and in several transportation applications.
Westport Fuel Systems is the proud inventor of HPDI.
