BMW 5 Series: Solenoid valve injector
Measures at the solenoid valve injector
The following graphic illustrates the differences between the EURO 6b and EURO 6c versions:
EURO 6 measures, solenoid valve injector
- Solenoid valve injector HDEV5 Bx8 engine, EURO 6b
- Solenoid valve injector HDEV5 EVO Bx8 engine, EURO 6c
- Solenoid valve injector HDEV6 Bx8TU engine, EURO 6c
- Injector seat
- Injection pattern and volumetric distribution
The Bx8TU engines use the HDEV6 solenoid valve injector by Bosch. Due to the more stringent exhaust gas emission regulations required to meet the EURO 6c exhaust emission standards, technical changes were again made to the solenoid valve injectors.
Due to the fuel system pressure increase from 200 bar to 350 bar, the solenoid valve injectors HEDV6 were optimized using suitable materials and coatings. The injection pattern and volumetric distribution have not changed compared with the HDEV5 EVO.
The repair instructions that are currently valid must be carefully followed when removing and installing the injectors in Service. An excessive rotational angle at the injector shank, and excessive tensile and compressive forces during removal and installation can lead to damage and therefore leaks in the fuel system.

Safety information
Warning
The system is designed to operate in certain
conditions and circumstances. Due to conditions
or other factors, the system may not respond.
There may be a risk of accident or risk
of damage to property. Actively intervene as
warranted. Refer to the information in this Owne
Functional principle
Depending on the speed, the system is guided by the lane edges or vehicles
driving ahead.
The position of the lane edges and the vehicle driving ahead is determined with
the help of five radar
sensors and the KAFAS stereo camera.
