Purpose and Compatibility

The injector set is designed for Diesel engines used in BMW 218d F45/F46 series and X1 F48 18d with the B47 unit. The design, based on OEM solutions, ensures correct fuel system operating parameters, appropriate injection pressure, and proper fuel atomization in the combustion chamber.

Thanks to the use of the original part number and an extensive list of interchangeable numbers, the set is prepared to work in many equipment variants and model years, which facilitates component selection during advanced service diagnostics.

Technical Characteristics of the Injector Set

The presented BMW injector nozzle set is a component of the common rail system responsible for precise diesel fuel metering. A correctly selected and functional injector set influences:

• stable idle operation – reducing engine vibrations and uneven running,
• proper acceleration dynamics – better throttle response,
• optimal combustion – maintaining fuel consumption at factory levels,
• lower exhaust emissions – correct cooperation with the particulate filter and exhaust gas aftertreatment system.

The injection system in the B47 engine operates under high pressure, therefore the use of appropriately selected injector nozzles is crucial for the durability of the high-pressure pump, turbocharger, and ancillary components.

Condition, Origin, and Benefits of Use

The offered BMW injector set is a used part from disassembly. This is a solution for users looking for an economical alternative to brand-new components while maintaining compliance with the manufacturer's factory specifications.

Choosing original injector nozzles from the aftermarket allows you to:

• reduce repair costs compared to purchasing new components,
• maintain the engine's factory operating characteristics without the need to use aftermarket parts with uncertain parameters,
• retain compatibility with the control electronics and engine control unit software.

Diagnostics and Prevention of the Injection System

Before installing the injector set, it is advisable to perform a full fuel system diagnosis, including measuring injector corrections, checking the common rail pressure, and assessing fuel quality. This helps to avoid re-damaging components due to contamination or improper operation of other parts.
