Changing the way fuel injectors are tested

The VPUD fuel injector test rigs are compatible with fuel injectors and safety valves from hundreds of different engine models.
Our cooperation with acknowledged engine designers has resulted in unique solutions like:

  • IOP SafeTest technology for MAN Diesel 2-stroke slide-valve fuel injectors
  • Scalable pump technology for Wärtsilä 2-stroke fuel injectors
  • Air-powered test rigs for 4-stroke engine injectors, allowing fast and precise adjustment of opening pressure second to none
  • Activators for electronically controlled injectors & pilot valves
  • Adapters for injectors with integrated fuel pump
  • Systems for test of combined gas-diesel injectors

The unique solutions of  OBEL-P ‘s valve pressure test units enables customers to:

  • Reduce emissions, fuel consumption and engine fouling.
  • Reduce Maintenance Costs
  • Replace two units with one
