Purpose and Technical Characteristics

The offered fuel rail with injectors is dedicated to M270 series engines installed in Mercedes W212 models with gasoline engines. The injector nozzles used are optimized for operating pressure and fuel system characteristics, allowing for the maintenance of the correct fuel-air mixture composition across the full range of loads.

A gasoline system requires stable, repeatable injection, making the complete fuel rail with injectors a key element influencing engine running smoothness, fuel consumption, and exhaust emissions. The use of an original Mercedes solution helps maintain the engine's factory parameters.

Application in M270 Gasoline Engine

M270 engines utilize precisely controlled gasoline injectors that must work in conjunction with the vehicle's control electronics and fuel system. A properly selected fuel rail:

• Stabilizes fuel pressure across all cylinders, minimizing delivery variations.
• Ensures uniform gasoline atomization, supporting efficient combustion and correct throttle response.
• Facilitates diagnostics and servicing – a complete fuel rail with injectors allows for faster replacement of the entire assembly.

By maintaining original geometry and mounting points, installation in the engine bay is predictable and does not require modifications to the fuel or intake system.

Benefits of Using Genuine Mercedes Injector Nozzles

Choosing genuine Mercedes injector nozzles, even used but functional, offers a sensible compromise between cost and quality. This type of component allows for:

• Restoring proper fuel system operation in cases of starting problems, rough idling, or power loss.
• Reducing the risk of improper fitment, which is common with aftermarket parts of uncertain specifications.
• Maintaining compatibility with engine control unit software, which is important for adaptations and service procedures.

Using components that comply with original design specifications helps maintain stable combustion parameters, contributing to smooth operation and predictable vehicle behavior in daily use.

Condition, Verification, and Part Selection

The fuel rail with injectors is a used part from a dismantled vehicle. Before reinstallation, it is recommended to subject this component to standard servicing procedures, such as leak testing, potential injector cleaning, and performance verification on a diagnostic bench. This minimizes the risk of further issues within the gasoline fuel system.

When selecting this part, pay attention to compatibility with the specific M270 engine version and vehicle year. Manufacturer markings and reference numbers are helpful for precise matching of the rail to a particular car model.
