The Technology

Current hydrogen rich fuel direct injectors suffer from low flow cross section, non-reliable closure and a non-optimized jet structure, which have a detrimental effect on the engine performance.
Achieving higher flow rate, shorter open-close timing and higher backward pressure resistance (in the cylinder) was done by improving the direct injector design. Changes in the injector design provide rapid and convenient calibration of the valve lift, sealing force and magnetic force which allow optimized injector configuration, well suited to different working conditions such as in-line pressure and flow rates. These properties were achieved while keeping a compact dimensions suitable to ICE requirements and improvement of air-gas fuel mixing.

Advantages

  • Calibration and adaptation to different working conditions and engine sizes
  • Improved sealing quality
  • Improved timing performance
  • Specifically design to use with hydrogen gas
  • Long service life due to calibration capability

Applications and Opportunities

  • Higher efficiency of internal combustion engine
  • Hydrogen injection to fuel cells, industrial processes such as chemical manufacturing, metal production, and electronics manufacturing
