DEF DELETE CUMMINS

CUMMINS UREA DELETE

Cummins is one of the manufacturers that uses SCR (Selective Catalytic Reduction) technology in their diesel engines, which requires the use of diesel exhaust fluid (DEF) or urea to reduce emissions of nitrogen oxides (NOx).

A “urea delete” or “DEF delete” for Cummins engines specifically, would refer to the process of removing or disabling the SCR system. This typically involves removing the DEF/urea tank, dosing unit, and catalyst, and reprogramming the engine control module (ECM) to disable the SCR system.

There are several reasons why someone might choose to delete the urea system on a Cummins engine:

1.-Cost: Urea/DEF is an additional fluid that needs to be purchased, stored, and refilled regularly. Removing the urea/DEF system eliminates this additional cost.

2.-Simplicity: Removing the urea/DEF system simplifies the engine, making it less complex, and less prone to issues or malfunctions.

3.-Performance: Removing the urea/DEF system can improve the performance of the engine by reducing the amount of exhaust gas that is recirculated back into the intake.

4.-Emissions: SCR systems are a crucial component in reducing emissions of nitrogen oxides, removing it might affect the emissions levels

It’s important to note that removing or disabling the urea system in a Cummins engine may not be legal in all jurisdictions, and can also void the vehicle’s emission warranty, so it’s important to check the laws and regulations before doing any modification. Additionally, It’s also important to know that removing these systems makes the engine illegal to use on public roads.
