Application in OM651 Engine

The presented injector for OM651 diesel engine operates within a precise fuel supply system, responsible for the proper atomization of diesel fuel in the combustion chamber. A correctly selected injector nozzle helps maintain stable engine operation, reduce smoke, and preserve the factory power and torque parameters.

In OM651 engines, the use of the appropriate injector is crucial for:

• maintaining smooth idling, free from vibrations and misfires,
• proper cold starting, especially in low temperatures,
• controlling fuel consumption and reducing excessive exhaust smoke.

Technical and Fuel Characteristics

This injector belongs to the category of injector nozzles and is designed for use with Diesel fuel. The component's construction is adapted to the high operating pressures typical of modern common rail systems, enabling precise fuel delivery across a wide range of engine loads.

A properly selected injector nozzle:

• stabilizes the combustion process across the entire RPM range,
• reduces the risk of piston overheating and excessive thermal load on the engine,
• supports compliance with emission standards, when the engine's ancillary equipment is functioning correctly.

Component Condition and Benefits of Installation

The injector is offered as a used part, allowing for economical repair of the injection system while maintaining the original manufacturer's specifications. This type of solution is particularly beneficial for vehicles with intensive use, where a reasonable service cost is important while preserving correct engine operating parameters.

Selecting the right injector nozzle for a Mercedes W204 or W212 enables:

• reducing the risk of incorrect fuel dosing,
• decreasing the load on the high-pressure pump,
• maintaining predictable vehicle behavior during acceleration and under load.

Diagnostics and Preventive Maintenance of the Injection System

When replacing an injector in a diesel engine, it is advisable to pay attention to symptoms typical of wear, such as uneven running, increased fuel consumption, or smoke under load. It is good practice to combine the installation of a functional injector with checking operating parameters on a diagnostic tester and assessing the condition of other fuel system components.
