Application in OM651 Engine and Compatibility

The presented injector holder mount has been developed for the OM651 engines used in Mercedes C-Class W204, E-Class W212, S-Class W221 models, as well as in W906 commercial vehicles. It is responsible for the stable seating of the injector in the cylinder head, which reduces the risk of leaks, exhaust blow-by, and improper fuel atomization.

The dedication to specific Mercedes vehicle generations allows for maintaining factory assembly geometry, which is crucial for correct injection timing and maintaining diesel engine performance parameters.

Technical Characteristics and Function in the Injection System

The holder operates in the demanding environment of a diesel engine, where high injection pressures, variable temperatures, and vibrations occur. Its function is to:

• maintain constant pressure of the injector against its seat in the cylinder head,
• ensure axial alignment of the injector nozzle relative to the combustion chamber,
• limit micro-movements of the component that could lead to wear of the seat or seals,
• stabilize the operation of the injection system under varying engine load.

A correctly selected injector mount directly impacts uniform fuel delivery, exhaust emissions, and engine running smoothness, especially in diesel engines where injection precision is paramount.

Component Condition and Benefits of Using an Original Part

The offered kit is from the Mercedes parts group and is an original component, which translates to maintaining factory manufacturing tolerances and full compatibility with the OM651 engine design. Thanks to this, the holder works correctly with the cylinder head, injector, and other fuel system components without requiring modifications.

Choosing an original injector holder mount means:

• maintaining the connection rigidity designed by the manufacturer,
• reducing the risk of leaks around the injector seat,
• easier diagnostics and servicing in the future, due to compliance with technical documentation.

Importance of Proper Diesel Injector Mounting

In engines powered by Diesel fuel, any play or deformation in the injector mounting area can result in a drop in compression, exhaust blow-by, and consequently increased fuel consumption and unstable engine operation. Using the appropriate injector holder in the OM651 engine helps to:

• maintain correct pressure in the combustion chamber,
• reduce noise and vibrations associated with improper injection,
• increase the durability of injector seats and seals under the injector.
