Application and Function in the AdBlue System

The presented diesel engine injector nozzle operates within the Selective Catalytic Reduction (SCR) system, where it doses the AdBlue solution into the exhaust gas stream. Proper atomization of the agent is crucial for effectively reducing nitrogen oxides and maintaining compliance with emission standards.

The injector works with the OM608 engine in the Mercedes W177 model, ensuring:

• stable AdBlue dosing across a wide range of engine loads,
• proper operation of the SCR catalyst and reduced risk of exhaust system clogging,
• maintenance of exhaust emission parameters at the level specified by the manufacturer.

Technical Characteristics and Compatibility

As a component in the injector nozzles category, this product is designed to operate in a demanding environment of high temperatures and variable pressures. The injector's construction is adapted to the specifics of diesel engines and AdBlue exhaust aftertreatment systems.

To ensure correct vehicle compatibility, pay attention to:

• compatibility with the OM608 unit in the W177 body style,
• fuel type – Diesel, which determines the operating characteristics of the entire fuel system,
• manufacturer's markings and interchangeable numbers, which allow matching the component to a specific factory configuration.

The injector is from the Mercedes brand, which helps maintain consistency with the vehicle's factory specifications and facilitates integration with the existing system.

Component Condition and Installation Aspects

The offered AdBlue injector is a used part, allowing for an economical repair of the SCR system while maintaining the original design. This type of solution is often chosen for servicing heavily used vehicles where both cost and compliance with factory solutions are important.

During installation, it is recommended to:

• thoroughly clean the mounting seat and the AdBlue supply lines,
• check the system for leaks after installing the injector,
• perform computer diagnostics to clear any errors and verify operating parameters.
