Application and Technical Characteristics

The presented injector is dedicated to BMW F-series models with LCI facelift, equipped with the B47 diesel engine. The nozzle's design has been developed to meet the requirements of modern common rail injection systems, enabling accurate diesel fuel atomization in the combustion chamber and maintaining the correct operating pressure across the entire load range.

As an original BMW part, the injector maintains factory operating parameters, supporting correct mixture combustion, reduced smoke, and sustained nominal engine performance. The use of the correct injector nozzle is crucial for even operation of all cylinders and for protecting components such as the turbocharger or the particulate filter.

Benefits of Using an Original BMW Injector Nozzle

Selecting the right injector for the B47 engine directly impacts the engine's durability and the vehicle's user comfort. Using an original BMW injector nozzle allows for, among others:

• Stable Fuel Delivery – reducing vibrations, uneven idling, and power loss.
• Improved Diesel Driving Refinement – reducing combustion noise and enhancing throttle response.
• Fuel Consumption Optimization – proper fuel spray formation promotes efficient combustion.
• Exhaust System Protection – correct fuel dose and injection timing limit excessive smoke and DPF load.

By maintaining factory parameters, replacing a worn nozzle with an original BMW part helps restore predictable vehicle behavior and reduce the risk of secondary failures resulting from improper fuel injection.

Component Condition and Vehicle Matching

The offered injector is a used part, allowing for an economical restoration of the injection system's functionality while maintaining the original manufacturer's specifications. Before installation, it is recommended to verify compatibility with the specific engine version and compare the markings with the currently installed component to ensure full compatibility with the fuel system and engine control unit.

In case of replacing a single injector nozzle, it is advisable to consider checking other fuel system components to avoid dosing differences between cylinders. A correctly selected and functional injector significantly influences the even load distribution on the engine and the reduction of vibrations transmitted to the body.

Injection System Diagnostics and Prevention

Symptoms of wear or damage to diesel injector nozzles – such as starting difficulties, smoke, power loss, or increased fuel consumption – often appear gradually. To better understand the symptoms and consequences of neglecting the injection system, it is worth reading the article Diesel Injector Failures – How to Recognize Them and What Their Neglect Entails, which discusses typical symptoms, diagnostic methods, and the consequences of driving with faulty injectors.

Regular monitoring of engine operating parameters and prompt reaction to the first signs of improper fuel injection help reduce repair costs and maintain stable, predictable operation of the diesel engine in the long term.
