Purpose and Role in the SCR System
The SCR AdBlue Injector operates in close proximity to the selective catalytic reduction converter, where it doses the agent based on signals from the engine control unit. A properly selected component ensures:
- stable operation of the exhaust gas aftertreatment system in 3.0 TDI diesel engines,
- maintaining the efficiency of the SCR catalyst across a wide range of loads and temperatures,
- reducing the risk of limp-mode associated with AdBlue dosing errors.
Thanks to its appropriate spray pattern, the urea solution mixes evenly with the exhaust gases, promoting efficient NOx conversion and improving the overall performance of the exhaust system.
Benefits of Using an Original Injector Nozzle
The selection of the correct injector nozzle in the SCR system directly impacts vehicle operation. Using a component that matches the factory specification allows for:
- correct AdBlue dosing without excessive agent consumption or under-dosing,
- stable exhaust emission parameters, which facilitates passing periodic technical inspections,
- reduced risk of exhaust system clogging by crystalline deposits,
- better compatibility with engine electronics and NOx sensors.
For diesel engines like the 3.0 TDI, a functional AdBlue injector is crucial for maintaining a balance between performance, fuel consumption, and emission levels.
