Abstract
In recent years, the air pollution problems and the influence to human which is caused by NOx and PM from diesel engine exhaust gas become severe social problems. More effective post-processing technology is desired. Although the use of DPF is now a leading technology for PM removal, the problem exists on the soot incineration or regeneration at low temperature. In the present study, a regeneration of DPF using ozone generator, and removal of NOx after DPF using ozone generator with the Na_2SO_3 was investigated. The targets are stationary and marine diesel engines. As a result, the regeneration of DPF could be confirmed, and NOx could be removed by 75%.
