Application in Mercedes W176, W204, W212 Models

The presented gasoline injector has been developed for popular Mercedes compact and mid-size class models such as the W176, W204, and W212. The design, compliant with the manufacturer's standards, enables the maintenance of correct fuel rail pressure, proper spray pattern angle, and stable idle and under-load operation.

Thanks to its factory design, the injector works with the original engine control unit, the OBD diagnostic system, and factory injection maps, which facilitates adaptation after installation and reduces the risk of ECU memory errors.

Technical Characteristics of the Gasoline Injector

As a component from the injector nozzles category, this fuel injector is responsible for precise gasoline delivery to the combustion chamber. Appropriately selected flow parameters and needle opening characteristics allow for:

• stable fuel delivery across the full engine speed range,
• even operation of all cylinders, which translates to improved engine smoothness,
• maintenance of the correct mixture composition during cold starts and under high load conditions,
• efficient gasoline combustion, contributing to the maintenance of factory performance and fuel consumption.

The injector is designed for gasoline fuel systems, with appropriately selected resistance to temperature and fuel rail pressure, which is important for long-term operation.

Benefits of Using an Original Mercedes Injector Nozzle

Choosing an original Mercedes fuel injector allows you to maintain the parameters specified by the vehicle manufacturer. Key benefits include:

• factory compatibility with the engine – no need for modifications to the fuel or electrical system,
• correct interaction with sensors and the control unit, which reduces the risk of errors related to the air-fuel mixture,
• consistency with other components of the injection system, such as the fuel rail or high-pressure pump,
• maintaining predictable vehicle behavior during acceleration, constant speed driving, and in eco/comfort/sport modes.

This series of components is often used for standard replacement of worn injectors as well as for fuel system repairs after improper operation due to low-quality gasoline.

Condition, Installation, and Diagnostics of the Injection System

The offered injector is a used component, allowing for economical repair of the fuel system while maintaining the original manufacturer's specifications. Before installation, it is recommended to verify the fuel system's tightness, the condition of the seals, and to check operating parameters on a diagnostic tester after starting the engine.

When replacing the injector, pay attention to:

• cleanliness of the head seats and the fuel rail,
• correct tightening torque of the fasteners, in accordance with service documentation,
• injector adaptation in the engine control unit, if required for the specific model.
