8 FUELSYSTEM2.2LDICOR FUELSYSTEMCOMPONENTS: CommonRail It is a fuel reservoir having an integrated rail pressure sensor. (Fig. 3) Feature: 1600 bar operating pressure NOTE Whenever fuel rail is removed from the Engine, always cover the inlet and outlet openings of the rail with the protective caps. INJECTOR (Fig. 4) Solenoid operated Injectors capable of fuel injection at very high pressures with desired quantity and with desired injection advance. Injector is clamped with a claw. The injector is electronically controlled. It allows multiple injections with short intervals between each injections. NOTE Injectors not to be inter changed in field during service since individual injector characterization is different and I2C no. of each injector is fed to the ECU during engine assembly. Features: 1600 bar operating pressure Fast solenoid actuator 2 pilot injections and 1 main injection The Injectors have to be removed in case of the following reasons Compression pressure in each cylinder needs to be checked for any possible reason like high engine oil consumption, high blow by, low power and pickup. In case cylinder head has to be removed and disassembled. If Injectors are damaged due to dust entry in the high pressure fuel system. In this case replace the injectors. NOTE Replace the clamp mounting screw and washer every time it is removed. Remove the injectors with sealing copper washer one by one. If the Injector is stuck in the bore do not use a pulling tool as it may damage the nozzle holder. If the sealing washer is still in the injector holder well, use extractor to remove it.
