The Function of Diesel Exhaust Fluid (DEF)?

[McHannah]

Automotive Diesel Exhaust Fluid (DEF) serves to convert nitrogen oxides (NOx) in vehicle exhaust into harmless nitrogen and water, enabling vehicles to meet national emission standards. The consequences of not using DEF and methods to resolve DEF warning light alerts are as follows: Consequences of not using DEF: Excessive emissions that pollute the environment; oxidation of chemicals within the vehicle system, leading to clogged DEF injectors and potential system failure; reduced vehicle performance. The primary functions of DEF include treating exhaust to reduce pollutants, optimizing engine performance, and improving fuel efficiency. Methods to resolve DEF warning light alerts: Replace the DEF solution; replace the water heating valve; replace the DEF pump and power supply module connector.
