We pay high attention to the technology research and development, Therein we have cooperation with Chinese Academy of Sciences Lanzhou Institute of Chemical Physics (Resource Chemistry and New Environment Protection Material, New and High Technology Innovation Research Centre) in investigating and developing environmental protection automobile exhaust treatment devices, Like three way catalyst. The contents of science and technology reach the standards of national new and high technology industries. The products are tested in cars and the techniques meet European Ⅲstandard for exhaust emissions while the European Ⅳ standard is in the process.
