Purpose and Role in the Fuel System

The fuel rail with gasoline injectors is responsible for evenly distributing fuel to individual cylinders and maintaining the correct operating pressure in the system. In the M260 engine, the use of an appropriate fuel rail is crucial for:

• stable engine operation across the entire RPM range,
• correct mixture composition and efficient gasoline combustion,
• maintaining the nominal power and torque specified by the manufacturer,
• limiting fuel consumption and exhaust emissions to factory-set levels.

Selecting the correct fuel rail for a specific M260 engine version is important for both repairs and professional fuel system upgrades.

Construction and Functional Parameters

The presented fuel rail for gasoline engines is a complete assembly with pre-installed injectors, which simplifies installation and reduces the risk of errors during system assembly. The design intended for M260 units in the W177 body ensures:

• precise fuel metering by each injector,
• appropriate spray pattern geometry adapted to the M260 engine's combustion chamber,
• compatibility with the factory engine control unit and injection maps,
• maintaining correct cold start and high load characteristics.

The system is designed to operate with gasoline, which is crucial when selecting injection components for a specific engine type.

Practical Application and Benefits of Installation

Installing a complete fuel rail with injectors in place of a worn or damaged unit can, in many cases, restore proper engine running characteristics. In practice, this means:

• reduction of jerking and misfires during acceleration,
• smoother idle operation and reduced vibrations,
• easier starting in various temperature conditions,
• reduced risk of component overheating resulting from incorrect mixture composition.

For workshops specializing in the Mercedes brand, using a complete fuel rail is a convenient service solution that reduces repair time and simplifies fault diagnostics.

Used Product Characteristics

The offered fuel rail with gasoline injectors is a used part obtained from disassembly. Such components are often chosen as an economical alternative to new parts, especially for modern engines where the cost of brand-new components is high. When selecting a used part, it is advisable to pay attention to:

• compatibility with the specific engine version and vehicle year,
• correct manufacturer markings and reference numbers,
• absence of mechanical damage to the fuel rail body and injector seats.

A correctly selected fuel rail allows for the preservation of the engine's original operating characteristics without the need for intervention in the control unit's software.
