Fuel System 113 Diesel Control System
Injector
Description
☢
WARNING
As the Piezo-Injector operates under maximum DC 200V, there may be a risk of an electric shock
caused by shorted control line etc. So when repairing the injector or its wiring, disconnect the
battery negative (-) terminal from the battery and wait for about 30 seconds.
Components
The injectors are installed on the cylinder head and inject the compressed fuel stored in common rail into each
cylinder by ECM control signal. This consists of the piezo actuator, the hydraulic coupler which amplifies output of
the piezo actuator, the pressure control valve which moves the needle, the needle which opens or closes the
injection hole of the injector, the fuel inlet nipple, and the fuel return nipple
