Intended Use and Characteristics of the Injection System

The presented injector set system for BMW X1 E84 20D 20Dx is designed to work with the N47 diesel engine producing 177 HP. It is responsible for precise high-pressure fuel delivery, which is crucial for the engine's smooth operation, acceleration dynamics, and stable cold starts.

The components included in the set are compliant with the manufacturer's original concept, which facilitates installation in place of the original system. This allows for maintaining proper combustion parameters, reducing smoke, and preserving the correct torque characteristics across the entire RPM range.

Diesel Engine Fuel Supply Technology

The injection system in the Diesel N47 engine operates based on high-pressure fuel delivery, which requires precise calibration of all components. The applied technology enables:

• precise atomization of diesel fuel in the combustion chamber, improving the efficiency of mixture combustion,
• stable idle operation and reduction of engine vibrations,
• better throttle response at low and medium RPMs, important for everyday city and highway driving,
• maintaining proper fuel consumption while preserving the engine's factory performance.

A properly selected injection system directly impacts exhaust emissions, noise levels, and engine durability, which is particularly important in modern BMW diesels.

Benefits of Using the BMW Injector Set

Using a complete injector system dedicated to the BMW X1 E84 20D 20Dx ensures cohesive operation of all fuel supply components. In practice, this means:

• maintaining compliance with BMW's factory specifications for the N47 177 HP engine,
• easier diagnostics and servicing due to predictable fuel system behavior,
• reducing the risk of incorrect fuel delivery, which could lead to power loss or uneven engine operation,
• the possibility of restoring proper diesel engine operation after previous injection issues.

The system is designed for Diesel fuel, which is consistent with the factory configuration of the N47 unit in the BMW X1 E84 20D 20Dx.

Condition, Installation, and Service Application

The offered set comes from the group of used BMW injector nozzles, making it an attractive cost-effective alternative to new components, especially for operational repairs or restoring vehicle functionality after a fuel system failure. Before installation, standard service procedures are recommended: leak testing, verification of operating parameters on a diagnostic bench, and adaptation in the engine control unit according to manufacturer procedures.

A system configured in this way can be used for both routine repairs and comprehensive engine rebuilds, where maintaining the consistency of fuel supply components is crucial.
