Application in OM651 Engine

The presented injector for OM651 diesel engine operates with direct fuel injection, responsible for forming a precise dose of diesel fuel in the combustion chamber. A correctly selected component from this group is crucial for:

• Stable idle operation – reducing vibrations and RPM fluctuations,
• Proper cold start – particularly important in diesel engines,
• Maintaining adequate power and flexibility across the entire RPM range,
• Exhaust emission control – proper fuel atomization facilitates compliance with environmental standards.

Thanks to its compatibility with the OM651 unit, the injector works with the factory engine control unit, simplifying adaptation and diagnostics in service conditions.

Compatibility with Mercedes W176, W204, W212 Models

The Diesel injector for Mercedes W176, W204, and W212 has been designed with the factory fuel system architecture of these body generations in mind. Appropriate geometric and hydraulic matching allows for installation in:

• Mercedes W176 – compact body with OM651 engine,
• Mercedes W204 – C-Class with a diesel engine,
• Mercedes W212 – E-Class with the same engine type.

The selection of the correct injector for a specific vehicle version should always be confirmed based on catalog data and part numbers in the service documentation, which minimizes the risk of incorrect fuel system configuration.

Technical and Fuel Characteristics

The injector belongs to the category of Injector Nozzles and is designed for use with Diesel fuel. This means that the component's construction – flow channels, needle, nozzle – has been optimized for diesel fuel parameters such as viscosity, operating pressure, and the required fuel spray pattern.

Key advantages of this solution include:

• Precise fuel metering across a wide range of engine loads,
• Stable atomization promoting uniform mixture combustion,
• Compatibility with the factory common rail system used in the OM651 engine.

A component configured in this way allows for predictable engine behavior in both city driving and at higher highway speeds.

Condition, Selection, and Service Aspects

The offered injector is a used market component, which is an attractive solution for users looking for an economical yet original-equivalent part for their fuel system. Before installation, it is recommended to verify its operating parameters on a diagnostic bench and check for leaks to ensure proper functioning in the specific engine.

In case of problems with the diesel engine's operation – such as uneven running, smoking, or power loss – it is worth consulting a guide describing typical symptoms and diagnostic methods.
