[4] Injector (G2 Type) (1) Outline a. The injectors inject the high-pressure fuel from the rail into the combustion chambers at the optimum injection timing, rate, and spray condition, in accordance with commands received from the ECU. (2) Characteristics a. A compact, energy-saving solenoid-control type TWV (Two-Way Valve) injector has been adopted. b. QR codes displaying various injector characteristics and the ID codes showing these in numeric form (30 alphanumeric figures) are engraved on the injector head. The J05/J08 engine common rail system optimizes injection volume control 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 HINO Diagnostic tool.
