Some of you may not know we are able to carry out Petrol Injector testing and cleaning! We invested in an ASNU petrol injector machine and are able to service your injectors to help you optimize engine performance! We often add this service onto an Intake Valve Carbon Clean as whilst we are in the engine it makes sense to test and clean the injectors at the same time!
GDI is an abbreviation for Gasoline Direct Injection, a process where the fuel is injected directly into the combustion chamber. On a GDI system, the fuel is injected directly into the combustion chamber at a much higher pressure than manifold systems, up to 200 bar.
These systems now require fuel pumps and injectors made of stainless steel and must be capable of performing at a much higher specification than ones seen on previous manifold injection systems. Both designed to deliver very precise quantities of fuel at extremely high pressures and in short increments, in some cases for fractions of a millisecond.
To control these systems, the ECU is also of a higher specification and required to supply a higher current of up to 90v on some systems. There are many manufacturers of this type of system, but Robert Bosch is recognised as one of the leaders in the development of GDI Technology.
The ASNU system has been designed for comparing injector against injector at a safe operating level. The ASNU system allows the user to visually examine the injectors on an individual cycle or in sequential mode, where they can compare the performance of the injectors under a range of simulated Millisecond & RPM driving cycles already programmed into the ASNU system. The injectors can be operated at various RPM & MilliSecond settings, restricted only by the number of injectors being tested in the sequential testing operation.
Once tested we clean the injectors in the ultrasonic bath and replace any required seals.
