Purpose and Technical Characteristics

The offered injector set for BMW 520d N47 is designed to work with the Diesel engine type used in the facelifted (LCI) E60 and E61 models. The system's design is based on precise injector nozzles, responsible for proper high-pressure fuel delivery, which directly impacts engine smoothness, dynamics, and fuel consumption.

The set's components are from the original BMW fuel system, ensuring that factory operating parameters, spray pattern geometry, and compatibility with the N47 engine control electronics are maintained.

Benefits of Using the Injector Set

Replacing worn injection system components with a tested set from a dismantled vehicle allows for the restoration of correct engine operating parameters. The use of this product can lead to:

• More stable engine operation at idle and under load, without undesirable vibrations or misfires of the fuel-air mixture,
• More predictable throttle response, improving driving comfort in urban traffic and on the road,
• Reduced exhaust smoke during acceleration, resulting from proper diesel fuel atomization,
• Maintenance of correct fuel consumption values, which helps protect the particulate filter and other exhaust system components.

For owners of N47 diesel engines in the BMW 5 Series LCI, using a properly selected injector set is crucial for maintaining engine durability and reducing the risk of costly future repairs.

Category: BMW Injector Nozzles

The presented product belongs to the Injector Nozzles category, which are components responsible for precise fuel metering in diesel engines. For the N47 engine in the BMW E60/E61 LCI, correctly selected injector nozzles are particularly important due to high operating pressures and exhaust emission requirements.

Condition and Practical Application

The offered injector set for BMW E60/E61 LCI is a used product, sourced from a dismantled vehicle. This type of solution is often chosen by informed users seeking a compromise between repair cost and maintaining the original manufacturer's specifications. Using original used parts helps maintain the integrity of the fuel system without the need for aftermarket replacements with uncertain parameters.

The set is designed for diesel engines, making it particularly suitable for vehicles used intensively – both for long-distance travel and daily city driving, where the injection system is exposed to variable loads and frequent start-up cycles.

Injection System Diagnostics and Prevention

Before installing the set, it is advisable to perform thorough diagnostics of the fuel system to confirm that injectors or related components are indeed the source of the problems. A detailed guide on the symptoms and consequences of injector damage in diesel engines may be helpful – you can find it in the article "Diesel Injector Faults – How to Recognize Them and What Neglecting Them Entails". This will help you better plan the scope of service work and avoid unnecessary costs.
