Injector Purpose and Function
The injector nozzle in the 3.0 TFSI engine is responsible for precise fuel atomization in the combustion chamber, which directly impacts the smoothness of operation, performance, and fuel consumption. In TFSI gasoline engines, maintaining the correct fuel spray pattern and dose repeatability is crucial. Therefore, using an original Audi component helps preserve the engine's factory performance parameters.
The injector works with a high-pressure system, electronically controlled by the engine control unit. A correctly selected nozzle reduces the risk of:
- rough idling and misfires,
- increased fuel consumption with the same driving characteristics,
- excessive strain on the catalytic converter and exhaust system components.
Compatibility and Selection by Part Numbers
The presented injector belongs to the Injector Nozzles category and is dedicated for use in Audi vehicles with the 3.0 TFSI gasoline engine of the B9 generation. Selection is based on the OEM part number and interchangeable numbers – this allows for precise verification of compatibility with a specific engine version and car year.
To avoid purchase errors, it is advisable to compare the markings with the currently installed component or service documentation. Additional support can be found in the guide on verifying parts by OEM numbers, available in the article how to safely buy parts online by OEM numbers, which describes practical methods for checking component compatibility.
Gasoline System Technical Characteristics
The injector operates in a gasoline fuel supply system, which means different requirements compared to diesel units. In a TFSI engine, it is important to ensure:
- precise control of injector opening time under variable load,
- resistance to high temperatures in the combustion chamber,
- stable fuel atomization at high operating pressure.
Although the article diesel injector failures – symptoms and consequences of neglect concerns high-pressure units, the symptoms described there (loss of power, rough running, smoke) can be helpful as general indicators of when it's worth checking gasoline engine injectors as well.
Part Condition and Service Application
The offered injector is a used part, intended for service and repair applications in Audi A4 and S4 B9 vehicles with the 3.0 TFSI unit. This type of part can be used for replacing a single injector or as part of a broader fuel supply system service when it is necessary to restore proper engine operation after experiencing fuel delivery-related symptoms.
Choosing an original Audi injector nozzle allows for maintaining consistency with the engine control unit's factory calibration, which facilitates diagnostics, adaptation, and subsequent vehicle service.
