With the increasingly strict diesel engine emission standards, universal DPF filter has become one of the necessary technologies for diesel vehicle exhaust emissions to meet the standards.inquiry
Diesel engines have good fuel economy and power and are widely used in various industries, such as motor vehicles, generator sets, and ships. However, particulate matter (PM) emissions from diesel engines have always been a concern. PM can be suspended in the air for a long time, polluting the environment and affecting human physical and mental health. With the increasingly strict diesel engine emission standards, universal DPF filter has become one of the necessary technologies for diesel vehicle exhaust emissions to meet the standards.
Working principle of wall-flow universal DPF filter.
The two ends of the adjacent honeycomb pores are alternately blocked, forcing the airflow through the porous wall, and the particles are trapped in the wall hole and the entrance wall, and the trapping efficiency can reach more than 90%.
We can provide cordierite diesel particulate filters (DPF) and silicon carbide (SIC) DPF.
• Cordierite DPF is widely used in heavy truck emission control. At the same time, it also has the advantage of low thermal expansion coefficient and can be made into a monolithic structure.
• SIC DPF has high mechanical strength, is not easy to fatigue, is resistant to acid and ash corrosion, but also has a large heat capacity and thermal conductivity, and a high thermal expansion coefficient.
