How to Treat Automotive Exhaust?

[LeAmara]

There are mainly the following methods for treating automotive exhaust: 1. Direct method: First, the carbon particles in diesel engine exhaust are captured by a collector and catalytically converted. The nitrogen oxides in the exhaust are then reduced or directly decomposed in a second catalytic converter using an appropriate reducing agent. 2. Indirect method: Simultaneously eliminate carbon particles and nitrogen oxides in the exhaust on a catalytic collector, that is, use the particulate matter (PM) collected on the filter to reduce (NOx). Here are some other introductions: 1. Introduction: Diesel engine exhaust has an extremely complex chemical composition, and the composition of the exhaust varies significantly with the engine's operating conditions. 2. Types: The emitted pollutants include carbon particulate matter (PM), nitrogen oxides (NOx), CO, and hydrocarbons (HC), among others.
