Purpose and Role in the Fuel System

The Mercedes injector nozzle for Vito W639 and Sprinter W906 models with the OM646 engine is responsible for the precise atomization of diesel fuel within the combustion chamber. The correct injection characteristics directly influence:

• Stable idle operation and reduced engine vibrations,
• Smooth acceleration without jerking or power loss,
• Fuel consumption control under typical operating conditions,
• Reduced exhaust smoke and maintenance of proper emission parameters.

A properly selected injector nozzle is particularly important in diesel engines, where the precision of the fuel dose and injection timing determines the engine's running smoothness and durability.

Technical Characteristics and Compatibility

This component belongs to the Injector Nozzles category and is designed for Diesel fuel systems. Using an original Mercedes solution ensures:

• Original engine operating parameters for the OM646 in Vito W639 and Sprinter W906,
• Correct fuel pressure and spray pattern across the entire load range,
• Compatibility with the factory engine control unit and injection maps.

The injector nozzle has an assigned OEM part number and associated interchangeable numbers, which facilitates the selection of the correct part based on service documentation or manufacturer catalogs, eliminating the risk of using an unsuitable replacement.

Condition, Origin, and Benefits of Use

The offered Mercedes injector nozzle is from the used parts segment, allowing for an economical repair of the injection system while maintaining original manufacturer specifications. This solution is particularly beneficial when:

• a single injector needs replacement in an already operational engine,
• it is important to maintain compatibility with factory equipment rather than using random aftermarket parts,
• the ability to match the existing fuel system configuration is crucial.

Using an original injector nozzle helps reduce the risk of starting problems, power drops, or excessive smoke, which are typical issues with faulty or incorrectly selected injection components.

Diagnostics and Operation of the Injection System

When replacing an injector nozzle in a diesel engine, it is advisable to pay attention to symptoms typical of wear or damage to injection components, such as uneven cold running, increased fuel consumption, or characteristic knocking sounds.
