Abstract (en)

[origin: EP1122418A2] The method involves setting a defined injection pressure as an initial pressure, increasing the injection pressure starting from the initial pressure while simultaneously checking whether the injection valves open, ending the pressure increase as soon as at least one of the valves no longer opens, reducing the injection pressure by a defined extent and using the reduced pressure as the maximum injection pressure.
