What is Exhaust Fluid?

[DelJocelyn]

Exhaust fluid is a liquid used to reduce nitrogen oxide pollution in diesel vehicle emissions. Below is an introduction to related automotive exhaust content: 1. Regulatory Standards: Automotive exhaust emission standards are quality requirements established to reduce harmful gas production, encouraging automobile manufacturers to improve technologies regarding emitted pollutants such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter. Both Europe and the United States have formulated relevant standards, while Mainland China primarily adopts European standards. 2. Air Pollution: Vehicle exhaust is another major factor in air pollution, containing carbon monoxide, nitrogen oxides, and other solid particles that adversely affect human health—especially leaded gasoline, which poses greater harm. Different vehicles also emit distinct odors. Automotive repair experts note that normal exhaust should be colorless and odorless, whereas varied colors or unusual smells in vehicle emissions may indicate potential malfunctions.
