Direct injection GDI, FSI, TSI, TFSI

Cleaning of injector

  • External ultrasonic
  • Internal specialized chemical detergent under pressure up to several hundred bars depending on the injector generation

Testing of injector

  • Electronic with accurate weighing of injection doses for various pressures and opening times
  • Spray test at high pressure
  • Injector Reaction Test - Determine how many microseconds elapse from current drive to actual gasoline injection. The test is performed by a piezoelectric sensor mounted in the injection chamber of the device.
  • Test at the same fuel pressure at which the injector operates in the engine
  • Revitalization of the piezo injector stack of the Siemens VDO injectors, which require this

Depending on the generation of the injector, the maximum fuel pressure is between 120 bar and up to several hundred bars in the latest solutions.
After each test, we provide a protocol with detailed results.

Benefits for the customer

  • Specialized injector cleaning can improve it
  • Advanced testing simulates engine conditions, after the test you will find out if and which injectors need replacing
  • Revitalization of the piezo stack restores its parameters
