Purpose and Function in the Injection System
The injector mounting bracket for Mercedes W204 with OM651 engine is responsible for the rigid, repeatable seating of the injector in the cylinder head bore. Correct clamping and guidance of the injector are crucial for:
- maintaining combustion chamber seal around the injector seat,
- stable injector nozzle operation under varying engine loads,
- reducing vibrations and micro-movements that can lead to leaks or seat damage.
This component works with a Diesel injection system, where precise injector positioning directly influences the fuel spray pattern, engine running smoothness, and exhaust emissions.
Construction and Fit for OM651 Engine
The bracket is designed as part of the injector nozzles category, tailored to the specific geometry of the OM651 engine head used in the Mercedes W204 class. Its construction ensures:
- factory fit to the injector seat in the diesel engine,
- appropriate rigidity and resistance to thermal and mechanical loads typical for diesel units,
- correct transmission of clamping force to the injector body, promoting even seating against the bore.
As an OEM Mercedes part, the bracket complies with factory assembly tolerances, facilitating installation and minimizing the risk of incorrect injector positioning.
Benefits of Using an Original Bracket
Using the original injector mounting bracket in a diesel engine offers tangible operational benefits:
- stable injector mounting reduces the risk of exhaust blow-by at the seat and carbon deposit formation,
- improved injection system repeatability promotes uniform operation of all cylinders,
- reduced load on the injector seat due to proper force distribution, which can extend cylinder head lifespan.
This solution is particularly important in modern diesel units, where injector positioning precision affects performance, fuel consumption, and noise levels.
Item Condition and Service Application
The offered bracket is a used part, making it an attractive option for repairs and servicing of the injection system in the Mercedes W204 with OM651 engine. It can be used for replacing a single injector or during comprehensive fuel system maintenance when restoring proper injector nozzle mounting is necessary.
It is always advisable to verify the correct bracket for a specific engine configuration based on manufacturer markings or service documentation to ensure full compatibility with the vehicle's injection system.
