The nozzle often appeared without fuel injection, visual inspection Injector injector removed, if the injector calibration equipment, fuel injector can be relocated checksum Taiwan by Technologyrequirements for verification. The injector calibration equipment may car test, the specific practices:

Remove the fuel injection nozzle and spray hole towards the external high pressure tubing, and then start the engine so that the fuel injection pump work, observe whether the injector fuel injection. If injector available screwdriver regulator screw on the injector gradually spin out, so that the regulator spring preload gradually reduced, then observe the injector effect, if the fuel injection is a good regulator spring tune given the pressure is too high, or due to the injection pump oil pressure is too low.
