Westport's Joint Venture, Cespira, Unveils Enhanced HPDI 3.0 Fuel System

Cespira, the joint venture between Westport and Volvo Group, has announced new technical details about its HPDI 3.0 fuel system.

The latest generation of high-pressure direct injection technology retains proven combustion principles while advancing fuel rail-pressure control, hardware durability, and system integration.

HPDI 3.0 supports liquefied natural gas (LNG) and renewable bio-based liquefied natural gas (bioLNG) today while preserving adaptability for future low- and zero-carbon fuels.

The new fuel system's architecture improves fuel economy and engine performance, simplifying OEM calibration and unlocking greater power and efficiency from high-performance compression-ignition engines.
