Technical Characteristics of the 1.4 TDI Injector

The presented component belongs to the Injector Nozzles category and is designed for the 1.4 TDI diesel engine. The pump injector design combines the functions of a pump and an injector in a single unit, enabling high injection pressure directly at the combustion chamber. This solution promotes:

• precise atomization of diesel fuel in the combustion chamber,
• maintenance of stable engine operating parameters across the full load range,
• better control over fuel dosage, which translates to smoother operation and better fuel economy.

The injector works with a Diesel fuel supply system, making it crucial to maintain fuel cleanliness and regularly check the condition of the entire injection system.

Application in VW Polo 9N with BMS Engine

The VW Polo 9N BMS Fuel Injector Pump Injector 1.4 TDI has been developed for the power units used in this model, ensuring proper matching in terms of operating parameters and control. The correct injector nozzle directly influences:

• easier cold engine starting,
• smooth idling, without excessive vibrations or misfires,
• maintaining power and torque according to the engine manufacturer's specifications.

Selecting the right pump injector is particularly important for small-displacement engines, where any loss of injection system efficiency quickly leads to a noticeable drop in performance.

Benefits of Using an Original Injector Nozzle

Choosing an original Volkswagen injector nozzle helps maintain factory engine operating parameters and reduces the risk of problems typical for faulty injectors. A correctly selected pump injector aids in:

• reducing fuel consumption through precise dosage,
• reducing smoke and exhaust emissions, which is important for technical inspections,
• protecting cooperating components such as pistons, valves, and the turbocharger from the effects of improper combustion.

Component Condition and Installation Recommendations

The offered pump injector is a used component, which in practice means it requires professional installation and verification of operating parameters after installation in the vehicle. It is recommended to have the installation performed by a specialized service center equipped with the appropriate tools for:

• checking the tightness of the injection system,
• verifying fuel correction values in the engine control unit,
• assessing engine operation under load after replacing the component.

This approach minimizes the risk of repeated disassemblies and allows for quick detection of any irregularities in the fuel supply system's operation.
