With reference to the technical requirements of Corning Incorporated, after several years of research and development, our company improved the existing technical equipment. We can produce diesel particulate filters with maximum diameter up to 330mm, with averge pore diameter of 10 ~ 12μm, and porosity close to that of the world's advanced level. We were the first in China to industrialize diesel particulate filters with “large diameter, multi-pores, high porosity”. Meanwhile, we’ve also undertaken a task in 2012 National Industry Promotion and Technological Transformation Special Fund Support Project to produce nitrogen and oxygen sensors and catalytic converter post-processing system used in medium and heavy-duty diesel vehicles.
