Abstract
Diesel vehicles have advantages over gasoline vehicles in fuel economy,with a big feature of less CO2 emission. However, it is well known that diesel vehicles exhaust nitrogen oxide (NOx) and the particulate matter (PM) , which causes air pollution. In order to encourage the broad use of diesel vehicles, it is necessary to develop clean diesel engines that are installed with a revolutionary high-performance after-treatment devices such as DPF, CSF. In this report, the recent trends of R & D's of the advanced after-treatment devices are introduced.
