Intended Use and Compatibility

The offered fuel injector for OM646 engine is designed for use in Mercedes Vito W639 and Mercedes Sprinter W906 vehicles with a diesel engine. The OEM construction guarantees proper geometric fit to the cylinder head, correct sealing in the bore, and compliance with the fuel injection system's factory operating parameters.

This component belongs to the injector nozzles category, meaning it is responsible for precise diesel fuel metering directly into the combustion chamber. This allows for maintaining the correct rail pressure, uniform cylinder operation, and proper engine response under load.

Technical Characteristics of the Injector

The injector operates within a Diesel fuel system, where precise fuel spray formation and dose repeatability are crucial. The nozzle design enables:

• stable fuel atomization across a wide RPM range,
• maintaining the correct mixture composition in the cylinder,
• reducing smoke during acceleration and under load,
• smoother operation of the OM646 unit.

The original Mercedes standard manufacturing promotes compatibility with the factory engine control unit map, which is important for diagnostics and post-installation adaptation.

Practical Application and Benefits of Installation

The good working condition of the injector directly impacts the vehicle's operational parameters. Installing the offered injector nozzle can help in:

• reducing rough idling,
• decreasing the risk of misfires in individual cylinders,
• improving cold diesel engine starting,
• maintaining proper fuel consumption in daily operation.

For OM646 units used in Vito and Sprinter, a functional injector is key to maintaining proper vehicle dynamics under full load and reducing excessive vibrations transmitted to the body.

Condition, Origin, and Servicing Aspects

The offered injector nozzle is a used component, originating from an original Mercedes fuel system. This type of component is often chosen as an economical servicing solution, especially for fleet repairs or when replacing a single injector in an OM646 engine.

Before installation, standard servicing procedures are recommended, such as:

• verifying the seal of the bore in the cylinder head,
• using new sealing washers in accordance with manufacturer recommendations,
• correctly tightening the mounting with the appropriate torque,
• performing injector adaptation in the control unit, if required for the specific vehicle.

Diagnostics and Technical Knowledge

If your Mercedes exhibits symptoms such as louder engine operation, smoke, or loss of power, it is worth checking the condition of the fuel injection system.
