Testing of common rail systems

For more than decades LIWO has been entrusted with leak test for large series injection pumps, valve technology, injectors and distributor technologies of Common Rail Systems.

Reference project: Leakage test for fuel rail under high pressure

Brief description:

  • Helium leak test for common rail applications
  • Equipped with one rotary indexing table each for testing/loading and final loading
  • Separate input/output stations
  • Part marking by grain unit
  • Sniffing device, optional
  • Limiting leakage rate: 1.8x10-4mbar*l/s
  • Test medium: helium
  • Test pressure: 450 bar 
  • Part cycle: approx. 30s
