Purpose and Role in the Injection System

The fuel injector for OM602 engine is responsible for precisely dosing diesel fuel into the combustion chamber, which directly impacts engine smoothness, dynamics, and fuel consumption. In Mercedes diesel engines, a properly functioning injector nozzle is crucial for maintaining stable idle, easy starting, and reduced exhaust smoke.

This component has been specifically designed for the OM602 engine's characteristics, ensuring it maintains the correct opening pressure, spray pattern, and response time required by this engine's design.

Construction and Functional Parameters

The presented injector belongs to the category of injector nozzles and works with the diesel fuel supply system. Its construction is based on a precisely manufactured spray tip and an opening control mechanism, enabling:

• stable fuel atomization in the combustion chamber, matched to the piston and cylinder head geometry of the OM602,
• uniform operation of all cylinders, resulting in reduced vibrations and smoother driving,
• reduced fuel consumption due to the correct spray pattern and dosing,
• decreased exhaust emissions through proper combustion of the diesel-air mixture.

Diesel injection systems are particularly sensitive to the quality and condition of injectors, making the use of an original nozzle with the correct characteristics essential for both engine performance and durability.

Benefits of Using an Original Injector Nozzle

Selecting the correct injector for a Mercedes W903 with an OM602 engine helps avoid problems associated with improper combustion and component overload. Using this part ensures, among other things:

• maintenance of the engine's original operating parameters,
• improved idle quality and performance under load,
• reduced risk of damage to pistons, valves, and turbochargers resulting from incorrect injection,
• easier diagnostics of the fuel system due to compliance with factory settings.

This product is from the Mercedes group, which facilitates matching it to specific vehicle configurations and ensures compatibility with other fuel system components.

Component Condition and Service Application

The injector is offered as a used part, making it an attractive solution for maintenance repairs on older commercial and passenger vehicles based on the W903 platform. This type of component is often chosen for:

• single-cylinder repairs when only one injector has been damaged,
• temporary repairs on a limited budget,
• restoring the original engine configuration after previous unsuccessful modifications.

Prior to installation, the standard workshop procedure is recommended, including parameter checks on a test bench and replacement of necessary seals according to the vehicle manufacturer's technology.

Selection and Additional Technical Information

To correctly select an injector for a specific Mercedes W903 model, it is advisable to use manufacturer markings and vehicle data. Product descriptions include information such as brand, fuel type, and condition, which help verify compatibility with your vehicle. Additionally, the system may use the OEM part number, interchange numbers, and SKU for precise component matching.
