D. Injector (G2 Type) a. Outline The injectors inject the high-pressure fuel from the rail into the combustion chambers at the optimum injection timing, b. Characteristics rate, and spray condition, in accordance with commands received from the ECU. ‡ A compact, energy-saving solenoid-control type TWV (Two-Way Valve) injector has been adopted. ‡ QR codes displaying various injector characteristics and the ID codes showing these in numeric form (30 base 16 char- acters) are engraved on the injector head. The 4HK1/6HK1 engine common rail system optimizes injection volume con- trol using this information.
When an injector is newly installed in a vehicle, it is necessary to enter the ID codes in the engine ECU using the ISUZU Diagnostic tool. c. Construction 56'SHIW FEWIGLEVEGXIVW 7SPIRSMH:EPZI 'SRXVSP'LEQFIV 4VIWWYVM^IH*YIP JVSQ6EMP 'SQQERH4MWXSR 2S^^PI7TVMRK 4VIWWYVI4MR 2S^^PI2IIHPI 5) -19-
