Emission control for gasoline vehicles:
• Core role: The exhaust gas produced by the gasoline engine after combustion contains a large number of harmful gases, and the three-way catalytic converter converts these pollutants into harmless substances through the REDOX reaction:
CO → CO2 (Conversion of carbon monoxide to carbon dioxide)
HC → H2O + CO2 (hydrocarbons break down into water and carbon dioxide)
NOx → N2 + O2 (Nitrogen oxides decompose into nitrogen and oxygen)

A Diesel Particulate Filter (DPF) is a device used to reduce particulate emissions from the exhaust of a diesel engine.
DPF uses high-performance ceramic materials (such as cordierite, silicon carbide) as the carrier, these materials have high heat resistance, corrosion resistance and good mechanical strength, can withstand high temperatures and complex working conditions. For example, silicon carbide (SiC) materials have better heat and thermal conductivity than traditional cordierite, and are more suitable for high load conditions
Structure

1. Shell:
Material: Usually made of stainless steel, with good high temperature and corrosion resistance
Function: Protect internal components from external mechanical damage and environmental impacts
2. Damping layer:
Material: Usually used expansion gaskets, such as aluminum silicate fiber and expanded mica
Function: Provides sealing, insulation and stability to prevent high-temperature gas leakage
3. Carrier:
Materials: Common carrier materials include honeycomb ceramic and metal materials (such as stainless steel)
Shape: The carrier is usually designed as a honeycomb structure to increase the surface area of the catalyst and improve the catalytic efficiency
4. Catalyst coating:
Materials: Catalysts are usually composed of precious metals (such as platinum, palladium, rhodium) that are precisely sprayed onto the support
Function: At high temperatures, the catalyst can accelerate the REDOX reaction of harmful substances in the tail gas

Installation Instructions

The installation position of the three-way catalytic converter:
1. Located on the exhaust manifold: that is, the head section of the exhaust pipe, which is one of the most common installation positions of the three-way catalytic converter, is at the connection between the engine exhaust port and the exhaust pipe, and can contact the newly discharged high temperature exhaust gas for the first time, which is convenient for the treatment of harmful gases
2. In the first section of the exhaust manifold drum: generally located under the chassis of the car, from the appearance of the drum similar to the shape of a marching kettle or a long kettle, this position can make the three-way catalytic converter work in a more stable airflow environment, which is conducive to improving catalytic efficiency.
3. Between the front and back oxygen sensors: the oxygen sensor is used to monitor the oxygen content in the exhaust gas, in order to adjust the fuel injection and combustion state of the engine, the three-way catalytic converter between the front and back oxygen sensors can better play a catalytic role according to the feedback signal of the oxygen sensor to ensure the conversion effect of harmful substances in the exhaust gas.
4. In the middle of the exhaust system manifold and muffler: In this position, the three-way catalytic converter can purify the exhaust gas after the initial collection and diversion of the manifold, and then transfer the purified exhaust gas to the muffler for noise reduction.
