General info – IOP SafeTest Technology

Experience shows that the injectors can be damaged if tested incorrectly. The damage occurs because the condition during testing of the fuel injectors is different to the condition when the engine is running. Traditional testing, where multiple openings take place during the “Opening Pressure Test” and the “Atomising Test”, very easily damages the injector.  Therefore, the testing procedure needs to be modified.

Slide-valves were introduced in 2002 and today most new engines from MAN B&W are delivered with the new generation of fuel injectors. To ensure optimal injector performance, the injectors are to be tested at regular intervals, as specified by MAN B&W Diesel.
