Application in the 2.5 TDi AVR Engine

The presented fuel injector works with the 2.5 TDi AVR diesel engine used in the Volkswagen LT 35. This component is responsible for the accurate atomization of diesel fuel in the combustion chamber, which is crucial for proper torque, engine smoothness, and reduced exhaust smoke.

Thanks to its design tailored to the specific engine unit, the injector allows for maintaining factory engine operating parameters, such as:

• stable idle speed without undesirable fluctuations,
• correct response to load across the entire RPM range,
• efficient diesel combustion while maintaining the correct fuel dose.

Technical Characteristics and Role in the Injection System

The injector operates within a Diesel fuel supply system, where high precision in nozzle opening and closing is crucial. A properly selected component helps maintain:

• correct injection pressure within the range specified by the manufacturer,
• uniform fuel atomization in the combustion chamber,
• repeatability of doses between individual cylinder operating cycles.

These parameters are important for both the durability of the engine unit and for maintaining correct exhaust emission values and fuel economy.

Benefits of Using an Original Volkswagen Injector Nozzle

Using an original injector in the AVR engine brings a range of practical operational benefits:

• Assembly Compatibility – fitting into the cylinder head socket and the fuel system designed for the LT 35 eliminates sealing and positioning issues.
• Consistency with Factory Calibration – the nozzle opening characteristic aligns with the engine control strategy, facilitating the maintenance of correct injection maps.
• Reduced Risk of Uneven Operation – proper fuel atomization reduces the risk of vibrations, jerking, and power drops resulting from incorrect injection.

For diesel engines like the 2.5 TDi, the condition and quality of injectors directly impact engine lifespan, making the selection of a component with appropriate parameters particularly important.

Condition, Selection, and Diagnostics of the Injection System

The offered injector is a used part, allowing for an economical repair of the fuel supply system while maintaining the original design specifications. Before installation, it is recommended to verify the remaining fuel system components to ensure even operation of all cylinders.
