Description

technical field [0001] The invention relates to a motor vehicle engine in an internal combustion engine, and more particularly relates to a motor vehicle engine exhaust purification device. Background technique [0002] In recent years, scientific research has found that when the motor vehicle engine is working, the exhaust gas contains hundreds of components, including carbon monoxide CO, hydrocarbon HC, nitrogen oxides NO X , sulfur dioxide SO 2 , lead compounds and various solid particles such as PM, which seriously pollute the environment and endanger human health. There are mainly two ways to purify motor vehicle engine exhaust: internal purification and external purification. Internal purification is achieved by improving the structural design of the motor vehicle engine, controlling the combustion process, or using clean fuel; external purification is achieved by adding a purification device to the exhaust pipe of the motor vehicle engine. At present, the external ...
