Description:
A DEF Doser Injector (also called a Urea Injector, DEF Injector, or SCR Doser) 2511446C1 is a component in modern diesel vehicles that sprays DEF (Diesel Exhaust Fluid) into the exhaust system to reduce emissions.

Part Number: 2511446C1
Condition: New
Manufacture/Brand: Cummins

Fits 2511446C1 For Cummins Engines EPA13 15 liter ISX/QSX

Purpose of using 2511446C1

When DEF is sprayed into hot exhaust:

  • DEF converts into ammonia

  • The ammonia reacts in the SCR catalyst

  • Harmful NOx (nitrogen oxides) are converted into nitrogen + water

This is how diesel vehicles meet emissions laws.

3. Controlled by the ECM/PCM

The engine computer decides:

  • When to spray

  • How much to spray

  • Spray timing based on exhaust temperature & load
