Technical Characteristics of the Injector

The presented injector belongs to the category of injector nozzles and is factory-designed to work with a Diesel engine. Its construction ensures precise fuel metering, proper atomization in the combustion chamber, and stable engine operation across the full range of loads.

Its original Mercedes origin helps maintain compliance with the engine's factory operating parameters, such as injection pressure, fuel spray pattern, and nozzle opening time. This allows the injector to contribute to maintaining the proper running characteristics of the OM629 unit and reduce the risk of incorrect fuel mixture combustion.

Application in the OM629 Engine and Benefits of Installation

The OM629 Diesel Fuel Injector is intended for injection systems used in Mercedes ML and GL W164 models with a diesel engine. Using a component from the same design family as the factory part helps maintain:

• consistency of injection system operating parameters – eliminating the need for adaptations of aftermarket solutions with different characteristics,
• stable engine performance – proper fuel doses contribute to maintaining power and torque at the manufacturer's specified levels,
• smoother engine operation – correct fuel atomization reduces vibrations and uneven idling.

For the user, this translates to more predictable vehicle behavior, easier diagnostics, and the possibility of continued vehicle use while adhering to the original design specifications.

Used Condition – A Practical Approach to Repair

The offered injector nozzle is a used part, representing a sensible compromise between repair cost and maintaining the original manufacturer's specifications. In many cases, installing a functional injector from a dismantled vehicle allows for the restoration of correct fuel system operation without the need to invest in a new set.

This solution is particularly beneficial for repairs on individual cylinders or when diagnostics clearly indicate damage to a specific nozzle. Choosing an original part from the aftermarket also facilitates subsequent servicing and potential further testing of the injection system.

Diagnostics and Prevention for the Injection System

To maximize the potential of the offered injector, it is advisable to ensure proper diagnostics of the entire fuel system – from the high-pressure pump to the fuel rail and other nozzles. A helpful guide describing typical symptoms and consequences of neglect in this area can be found here: diesel injector faults – how to recognize them and what are the consequences of neglecting them. Thorough diagnostics before installation reduce the risk of repeat interventions and allow for a better assessment of the condition of other components.
