Hydrogen Engine

PHINIA’s portfolio includes low pressure H2 injectors for port fuel injection (PFI) configurations. For medium pressure port fuel and direct injection in hydrogen applications we provide the Direct Injector-Compressed Hydrogen Gas (DI-CHG injector) that meets the needs of powertrains with high flow capacity, optimized mixing, flexible packaging and advanced controls. The DI-CHG10 is package compatible with current production 7.5mm tip GDi injectors and suitable for power ranges up to 60kW/cylinder, whilst the larger 9.8mm tip DI-CHG15 injector extends the potential power to 90kW/cylinder for heavy duty commercial vehicle applications.

The injectors have been developed for large flow sections and optimal injector sealing. The specific materials chosen for the injectors ensure durability and help to avoid hydrogen embrittlement. The systems feature a controller and software that allows for a boost system upgrade, EGR and water injection as well as ignition and knock detection.

PHINIA has system specification, integration and calibration capabilities to deliver complete turn key hydrogen propulsion projects.
