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%.
