Background technique

Energy shortage and environmental pollution are global problems, and they are two major problems restricting the sustainable development of the automobile industry. Traditional cars not only consume a lot of petroleum resources, but also their exhaust is the main cause of air pollution and global greenhouse gas emissions. Governments and automobile manufacturers of various countries have begun to accelerate the control and improvement of automobile exhaust emissions.

The exhaust gas treatment technology of diesel engines at home and abroad is mainly reflected in three aspects: one is pre-engine treatment; the other is internal purification; the third is the research and development of after-treatment.
