• proper mixture combustion, which contributes to maintaining the engine's smooth operation.

Benefits of Using an Original Injector Nozzle

Using an original injector in the 2.0 TDI DTNB engine helps reduce the risk of problems typical for high-pressure systems. Precisely selected injector opening and closing parameters affect:

• even engine operation at idle and under load,
• efficient cold starts, without excessive smoke,
• maintenance of the correct torque characteristics across the entire RPM range.

By adhering to the factory design specifications, the injection system remains consistent with the engine control unit's maps, facilitating diagnostics and subsequent servicing.

Component Condition and Practical Application

The injector is offered as a used part, which is a cost-effective solution for users seeking original components at a reasonable price, while ensuring proper fitment for a specific engine variant. This type of component is particularly useful for:

• injection system repairs after diagnosing uneven engine operation or starting problems,
• targeted replacement of a damaged injector in a single cylinder,
• restoring the factory configuration after previous unsuccessful modifications.

Injection System Diagnostics and Prevention

When selecting an injector nozzle for a diesel engine, it is advisable to pay attention to symptoms typical of wear or damage to this component, such as uneven idle operation, power loss, or increased exhaust smoke.
