Purpose and Compatibility

The presented injection system for BMW F20, F30, and F31 LCI with B47 engine has been designed for the 125d and 325d diesel versions. The construction corresponds to BMW's factory solutions, which facilitates proper fitting with engine accessories, wiring harnesses, and the control unit.

The system is suitable for modern diesel units where precise fuel metering, stable rail pressure, and repeatable injection parameters across the full load range are crucial.

Technical Characteristics of the Injection System

As an element from the injector nozzles category, the kit includes components responsible for delivering fuel to the combustion chambers in the B47 engine. The high-pressure technology used enables:

• precise atomization of diesel fuel in the cylinder, promoting even mixture combustion,
• maintaining stable system pressure within the injection system across a wide range of engine speeds,
• accurate fuel metering depending on engine load and operating conditions.

The system is adapted for Diesel fuel, in accordance with the requirements of the B47 unit used in BMW F20, F30, and F31 LCI models.

Condition, Origin, and Benefits of Use

The offered BMW injection kit comes from the brand's original production line, which translates to proper fitment with other fuel system components and engine accessories. As a used part, it represents a cost-effective solution for users who expect parts with factory geometry and operating parameters while maintaining a reasonable service budget.

Using a complete injection system to replace worn-out components allows for:

• reducing starting problems with the diesel engine,
• decreasing the risk of uneven idling and jerking during acceleration,
• maintaining the proper dynamics of the B47 unit in the 125d and 325d versions.

Selection, Diagnostics, and Operational Safety

When selecting an injection system for BMW F20, F30, or F31 LCI with a B47 engine, it is worth paying attention to compatibility with the engine designation and body version. Properly selected injector nozzles and accompanying components are crucial for maintaining the correct mixture composition, exhaust emissions, and engine running smoothness.
