Product Description
Automobile exhaust gas recirculation valve (EGR valve) is a device for controlling engine exhaust gas, which is usually installed on the engine intake. The main function of EGR valve is to reintroduce a part of exhaust gas into the combustion chamber of the engine to reduce the emission of nitrogen oxides (NOx).
Specifically, the working principle of the automobile exhaust gas recirculation valve is to introduce a part of exhaust gas from the exhaust pipe into the intake passage of the engine by controlling the opening and closing of the EGR valve when the engine is working. These exhaust gases contain a certain amount of oxygen and nitrogen, which enter the combustion chamber after being mixed with fresh air, so as to lower the combustion temperature and reduce the generation of nitrogen oxides, thus reducing the engine emissions.
The functions of automobile exhaust gas recirculation valve mainly include the following points:
1. Reduce the emission of nitrogen oxides: The exhaust gas recirculation valve can reduce the generation of nitrogen oxides during engine combustion, reduce the emission of harmful gases in automobile exhaust, and meet the environmental protection emission standards.
2. Reducing combustion temperature: By introducing some exhaust gas, the temperature in the combustion chamber of the engine can be reduced, the generation of nitrogen oxides can be reduced, and the service life of the engine and exhaust system can be prolonged.
3. Improve fuel economy: Proper exhaust gas recirculation can improve combustion efficiency, improve fuel economy and reduce fuel consumption of automobiles.
Generally speaking, the automobile exhaust gas recirculation valve is an important emission control device, which can reduce the emission of nitrogen oxides, reduce the combustion temperature and improve the fuel economy by recycling part of exhaust gas, which is helpful to protect the environment, prolong the engine life and improve the automobile performance. Therefore, regular inspection and maintenance of the exhaust gas recirculation valve is an important measure to maintain the normal, environmentally friendly and efficient operation of automobile emissions.
