Description
Hydrogen injectors are components of the fuel system of gas piston engines that run on hydrogen or on natural gas with added hydrogen. The “Engine Solutions” division of the manufacturer develops and supplies injectors and ignition systems for mobile and stationary engines; the headquarters of the injection business is in Vienna, the leading automotive plant is in Poland, the competence center for ignition and control systems is a unit in Girard, Ohio, USA, and localized production for Asia is in Guangzhou. For power generation, the main application is stationary gas-engine generator sets and cogeneration plants.
The program covers three hydrogen supply methods. H2PFI — injectors that feed gas into the intake port upstream of the mechanical intake valve; H2DI — direct-injection injectors into the main combustion chamber; H2ePCC — injectors for direct or indirect injection into the prechamber. The platforms are designated GV and GVC. For stationary plants below 1 MW, GVC10 (PFI) and GVC24 (DI) are used; for 2–4 MW units, GV40/GVC40; for large units above 10 MW, GV400; ignition is the AH2IS-S system. For mobile engines with displacement of 6–10 L, 10–13 L and from 15 L, GVC10, GV7/GVC13, GV8 and GV40/GVC40 with AH2IS-M ignition are intended.
The nozzle is adapted to the specific engine design, and top-feed and side-feed versions are available; the injectors provide high homogeneity of the air-fuel mixture in the cylinder and work on the low-pressure supply principle. A special alloy is used to protect against hydrogen embrittlement. The patented real-time ignition system adjusts spark energy within microseconds, reducing the risk of misfires, knocking and pre-ignition and extending spark plug life. The AdaptH2 complete solution (the manufacturer and Prometheus) combines the injector, adaptive ignition and prechamber for ultra-lean hydrogen combustion.
Operating experience is confirmed: more than 20 field engines run on injectors from the manufacturer with over 8,000 hours of operation, operation on 100 % hydrogen is achieved, and the first 1 MW hydrogen engine (INNIO) runs on H2PFI injectors; retrofitting of serial natural gas injectors for 100 % H2 operation is possible. Production follows automotive quality standards.
