Injector valves (206a-d), E39
| Injector valves (206a-d), E39 |
| Location |
The injectors are fitted in the engine bay, in the cylinder head under the intake ports.
Injector, cyl 1 (206a), E39
Injector, cyl 2 (206b), E39
Injector, cyl 3 (206c), E39
Injector, cyl 4 (206d), E39
| Main task |
The task of the injectors is to inject fuel directly into the combustion chambers.
| Type |
High-pressure, direct injection, returnless multiport fuel injection system with injectors placed inside the combustion chambers.
The injectors, all identical, consist of internally opening, electric solenoid valves with six holes that generate the desired spray pattern.
ECM, control module, E39 (590) controls each injector with 65 V, which opens the injector, and then holds it open with 12 V.
