HPDI (high pressure direct injection) for heavy-duty trucks and high horsepower applications HPDI is designed for heavy- and medium-duty trucks and high horsepower applications such as mine-haul trucks and power generators. Westport™ HPDI natural gas engines on the road are producing approximately 50% less nitrogen oxides (NOx), 80% less particulate matter (PM), and 20-25% less carbon dioxide (CO2) emissions than equivalent diesel engines.

CNG-DI (compressed natural gas direct injection) for light- to medium- duty trucks and city work vehicles Westport™ CNG-DI hot-surface ignition technology has been applied to light- and medium-duty commercial vehicle engines in the 2-litre to 10-litre range. Testing on prototype engines using HSI shows up to 20% less greenhouse gas emissions (mainly carbon dioxide) than equivalent diesel engines, and 30% increased fuel efficiency over current natural gas engines.

H2DI (hydrogen direct injection) We develop advanced fuel injection hardware, electronic controls, and provide research and engineering support for BMW and Ford’s hydrogen programs. Learn more about H2DI. ^top

HCNG (hydrogen-enriched compressed natural gas) for transit buses We calibrate natural gas engines to operate on a blend of hydrogen and compressed natural gas called HCNG. HCNG buses, powered by Cummins Westport LBSI engines, retain the same power and torque of natural gas buses, while producing about 50% less NOx. Learn more about HCNG. ^top

LBSI (lean burn sparked ignited) for transit buses and medium-duty trucks Cummins Westport engines use Lean Burn Spark Ignited technology and are designed to meet the most stringent emissions regulations and provide efficient and reliable service. They are certified to the toughest USA EPA 2005 (Environmental Protection Agency) and CARB (California Air Resources Board) regulations, as well as to EURO III emissions standards.
