PHINIA Presents Gaseous Fuel Injection and Ignition Systems at Vienna Motor Symposium 2026

PHINIA Inc. is presenting research and hardware demonstrations at the 47th International Vienna Motor Symposium, running April 22–24, 2026, to show that its gaseous fuel injection and ignition systems for hydrogen, compressed natural gas (CNG), and ammonia are ready for real-world deployment and capable of meeting Euro 7 emissions requirements.

The company's technical paper, "Future Gaseous Fuels: Latest Development in Injection, Ignition and Combustion," outlines advances across three fuel types. PHINIA's low-pressure gaseous injection technology is rated ready for current and future CNG applications, while its next-generation low-pressure direct injection system delivers improvements in power output, emissions control, and efficiency over conventional port fuel injection.

On a 13-litre commercial engine demonstrator converted from diesel to hydrogen using PHINIA's high-flow port fuel injection (PFI) injector, the company recorded an indicated thermal efficiency (ITE) exceeding 45 percent.

"Our latest research proves that gaseous fuels are not just theoretical; they are practically deployable today," said Jean Luc Beduneau, Director of Innovation & Engineering Excellence at PHINIA. "With the right technologies, internal combustion engines can significantly reduce emissions while maintaining performance, supporting the transition to lower-carbon sustainable mobility across a wide range of on-road and off-highway applications."

PHINIA's Flexispark ignition system is also on show, designed to handle the variable combustion characteristics of gaseous fuels — from ammonia to hydrogen while managing spark-plug wear.

At its stand in the Hofburg Vienna Conference Centre, PHINIA is displaying the Alpine Hy6 hydrogen internal combustion engine, developed in partnership with Alpine's Alpenglow hydrogen programme. A car fitted with the Hy6 engine and PHINIA's fuel system has recorded a top speed of 312.9 km/h.

"The transition to lower-carbon mobility requires solutions that are innovative, scalable, and ready for real-world use," said Todd Anderson, Chief Technology Officer at PHINIA. "Advanced combustion technologies, combined with alternative fuels such as hydrogen, offer a compelling and practical route to reducing emissions while preserving the performance and durability customers expect."
