Purpose and Technical Characteristics

The presented fuel injection system component has been designed to work with the Diesel engine in BMW E90 316d and 318d models equipped with the N47N unit. The design of the fuel injection system in these engines requires precise control of high-pressure fuel delivery, making appropriately selected injector nozzles crucial for maintaining correct operating parameters.

The fuel injection system in this application is responsible for, among other things:

• stable fuel metering across the full engine load range,
• maintaining proper N47N unit operation at idle and during acceleration,
• reducing smoke emissions and supporting the correct functioning of the exhaust gas aftertreatment system.

Benefits of Using a Functional Fuel Injection System

In BMW 3 Series E90 diesel engines, the quality of injector nozzle operation directly impacts performance and driving economy. Using a functional fuel injection system component allows for:

• smoother engine operation across the entire RPM range,
• better throttle response when starting off and overtaking,
• stable fuel consumption in line with the N47N unit's design specifications,
• reduced risk of improper combustion, which can lead to accelerated wear of other components.

In the case of diesel units, neglecting the condition of the injectors can result not only in reduced driving comfort but also in increased mechanical stress on the engine and its accessories.

Product Condition and Service Application

The offered fuel injection system component is a used product, making it an attractive service solution for users seeking parts at a reasonable price while maintaining compliance with original BMW specifications. This type of component is particularly useful for:

• comparative diagnostics (swapping the component to verify a fault),
• routine repairs on vehicles used intensively,
• restoring the functionality of the fuel system in fleet or private vehicles.

Prior to installation, the standard service procedure is recommended, including checking the fuel injection system's operating parameters on the vehicle or a diagnostic bench, in accordance with the vehicle manufacturer's guidelines.

Fuel Injection System Diagnostics and Prevention

For diesel engines like the N47N in the BMW E90, typical symptoms of injector nozzle problems include uneven cold running, power loss, increased fuel consumption, or smoking under load. To better understand the symptoms and consequences of neglect, it is worth consulting the guide: diesel injector faults – symptoms, consequences, and diagnostics. This allows for informed repair planning and selection of the appropriate service strategy.
