PHINIA Inc. is showcasing its latest gaseous fuel injection and ignition technologies at the International Vienna Motor Symposium, taking place from April 22–24, 2026. The company is presenting research and hardware demonstrations that highlight the real-world readiness of its systems designed for hydrogen, compressed natural gas (CNG), and ammonia, while also demonstrating compliance with upcoming Euro 7 emissions requirements.
At the 47th edition of the symposium, PHINIA’s technical paper titled “Future Gaseous Fuels: Latest Development in Injection, Ignition and Combustion” outlines advancements across three alternative fuel types. The company’s low-pressure gaseous injection technology is positioned as ready for current and future CNG applications, while its next-generation low-pressure direct injection system delivers improvements in power output, emissions performance, and fuel efficiency compared with conventional port fuel injection systems.
PHINIA also showcased a 13-litre commercial engine demonstrator converted from diesel to hydrogen using its high-flow port fuel injection (PFI) technology. The demonstrator recorded an indicated thermal efficiency exceeding 45 percent, highlighting the potential of hydrogen-powered internal combustion engines in reducing emissions while maintaining performance.
According to Jean Luc Beduneau, the company’s latest research demonstrates that gaseous fuels are no longer theoretical solutions but are ready for practical deployment. He noted that advanced fuel technologies can significantly reduce emissions while maintaining engine performance, supporting the transition to lower-carbon mobility across on-road and off-highway applications.
PHINIA is also presenting its Flexispark ignition system, engineered to manage the variable combustion characteristics of gaseous fuels such as hydrogen and ammonia. The system is designed to improve ignition performance while reducing spark-plug wear, addressing one of the key challenges associated with alternative fuel combustion.
At its display at the Hofburg Vienna Conference Centre, PHINIA is showcasing the Alpine Hy6 hydrogen internal combustion engine, developed in collaboration with Alpine as part of the Alpenglow hydrogen programme. A vehicle equipped with the Hy6 engine and PHINIA’s fuel system has achieved a top speed of 312.9 km/h, demonstrating the performance potential of hydrogen-powered combustion technology.
Todd Anderson emphasized that the transition to lower-carbon mobility requires scalable and practical solutions. He noted that advanced combustion technologies combined with alternative fuels such as hydrogen offer a compelling pathway to reduce emissions while maintaining the performance and durability expected by customers.
With its latest innovations, PHINIA aims to demonstrate that alternative gaseous fuels can play a key role in the future of sustainable mobility, bridging the gap between traditional combustion engines and fully electric solutions.
