Numerical analysis of catalytic efficiency of diesel exhaust purification based on multimedia aided regression model

Automotive diesel has become an international trend, and more and more attention has been paid to the purification of diesel engine. In the face of the European emission standards, we need to develop emission control technologies applicable to high standards. Outside purification is the key to this technology. In this paper, the technology of diesel engine purification outside and outside of China is analyzed. The principle, characteristics, treatment effect and application prospect of various methods are analyzed. In this paper, the process and influence of the tail gas production in diesel engine fuel combustion are expounded. The chemical characteristics and chemical reaction equations of harmful tail gas, the emission hazard of diesel engine and the method and significance of exhaust gas treatment are listed. With the continuous development of multimedia technology, multimedia teaching plays a more and more important role in the field of modern teaching. At the same time, multimedia teaching is a breakthrough in the traditional backward teaching mode. Multimedia assisted instruction is widely used all over the world, and it also faces many problems caused by improper use while improving students’ academic achievements. Multimedia assisted and regression models are adopted in this paper.
