Purpose and Function in the Fuel System

The complete fuel rail with injectors is responsible for accurate petrol delivery to the combustion chambers in the M264 engine, working in conjunction with the engine control system and pressure sensors. A correctly selected set from this group ensures:

• stable petrol engine operation across the full range of loads,
• proper fuel spray pattern from the injector nozzles,
• maintenance of the correct mixture composition in both city and highway driving modes.

The solution used in M264 units allows for precise fuel dose control, which translates to improved running smoothness, performance, and fuel consumption.

Set Construction and Technical Aspects

The presented set includes the fuel rail with mounted injectors, which simplifies installation and reduces the risk of errors during system assembly. The use of factory injector nozzle geometry promotes:

• even petrol atomization in each cylinder,
• repeatability of fuel doses at different operating pressures,
• proper cooperation with the original engine control unit in the Mercedes W205.

The system is designed to operate with petrol fuel, in accordance with the requirements of the M264 engine, which is important for component durability and resistance to operating conditions in the engine bay.

Condition, Selection, and Installation

This item is from the used parts category, allowing for an economical repair of the fuel system while maintaining factory-like characteristics. When selecting a fuel rail with injectors for a Mercedes W205 with an M264 engine, it is worth paying attention to:

• compatibility with the specific engine version for the given year,
• appropriate operating parameters for petrol (pressure, injection characteristics),
• compatibility with the existing electrical system and injector harness.

Professional installation, maintaining fuel system cleanliness and replacing seals, minimizes the risk of leaks and problems with starting or uneven engine operation.

Benefits of Using a Complete Fuel Rail

Using a complete set of injector nozzles in the Mercedes W205 with an M264 engine allows for:

• restoring proper vehicle dynamics after a failure or wear of previous injectors,
• reducing the risk of knocking due to proper petrol atomization,
• stabilizing idle RPM and improving throttle response,
• maintaining compliance with factory injection maps stored in the engine control unit.
