Purpose and Role in the Injection System

The offered diesel injector for Mercedes belongs to the Injector Nozzles category and is the final component of the fuel supply system in a diesel engine. Its function is to precisely atomize diesel fuel in the combustion chamber, which contributes to:

• stable operation of the OM602 unit across the entire RPM range,
• proper mixture combustion and reduced smoke,
• maintaining factory power and torque parameters,
• controlling fuel consumption in the daily operation of a commercial vehicle.

By preserving the original opening and spray pattern characteristics, this used OEM part allows for the restoration of proper engine running smoothness without the need for a costly replacement of the entire injector set.

Compatibility with Mercedes W901, W903, W905

The injector nozzle for OM602 engine has been specifically designed for Mercedes W901, W903, and W905 series vans. This means:

• geometry matched to the OM602 cylinder head and injector seats,
• compatibility with the diesel fuel system used in these generations,
• possibility of installation in place of the factory part without any modifications to the system.

Such precise fitting simplifies servicing and reduces vehicle downtime, which is particularly important for fleet and commercial applications.

Technical Characteristics and Benefits of Use

The injector operates within the fuel system of a diesel engine, where spray pattern and sealing are critical parameters. Using an original injector nozzle allows for:

• maintaining the correct injection pressure across the entire load range,
• reducing uneven idling and jerking during acceleration,
• minimizing the risk of excessive smoke and unburnt fuel odor,
• protecting cooperating components such as pistons, valves, and the turbocharger, thanks to more complete combustion.

Choosing a used OEM part is a sensible compromise between repair cost and maintaining factory performance, especially for vehicles that are used intensively but have a controlled service budget.

Diagnostics and Prevention for the Injection System

When replacing an injector nozzle, it is advisable to pay attention to symptoms typical of wear in diesel fuel system components, such as starting difficulties, power loss, or increased fuel consumption.
