Hydrogen Solutions

PHINIA is developing fuel injection equipment solutions that can meet the demands of both current and future emissions regulations in the automotive industry.

As EU and other countries have set high objectives regarding their carbon footprint, emission standards worldwide are becoming increasingly stricter. At the same time global OEMs are working diligently to find technological solutions for different drivetrains that comply with these standards.

The hydrogen injection system is a particularly critical component for hydrogen propulsion since hydrogen has a substantially lower density than diesel or gasoline. PHINIA is developing solutions for low, medium and high pressure applications.

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.

Hydrogen solutions contribute to carbon neutrality

Hydrogen propulsion, based on existing engine technology and able to leverage the available fuel supply network, is an attractive and fast-to-market solution for powertrains that contributes to the rapid decarbonization the world needs. It requires only slight adjustments to the internal combustion engine while still meeting both zero emission CO2 targets and future emissions regulations.

As a solution provider for hydrogen technology, PHINIA cooperates with OEMs in all vehicle segments – from passenger cars to light and heavy duty, on- and off-road. PHINIA can supply customers with components as well as with complete turnkey applications, having the capabilities to integrate the entire hydrogen injection system, including controller, software and calibration.
