Solenoid valve injector for common-rail systems

Operation of the solenoid valve injector

The rapidly switching CRI2 solenoid valve injector allows short injection intervals which inject into the cylinder the amount of fuel required for economical combustion, independent of the driving situation. Up to ten individual injections are possible per injection cycle. In addition, the injection process can be designed with high flexibility. Using multiple injections, the engine's fuel consumption and CO₂, pollutant, and noise emissions can be reduced.

Optionally, a Needle Closing Sensor can be integrated for system pressures of at least 2,000 bar; this significantly increases the injection accuracy over the service life. The CRI2-16 solenoid valve injector has a ball valve; variants from 1,800 bar allow higher system pressures owing to their pressure-compensated solenoid valve.
