| Abstract: | Environment is severely affected by a large amount of particles exhausted from diesel engine,among which PM2. 5 is the main reason for haze weather. Main research direction of environmental protection technology is to reduce diesel engine emissions, especially particulate emissions. From many aspects of fuel, interior control and particulate emission after-treatment technology,the paper has analyzed influencing factors of diesel particulate emissions and some control measures,expounding main technology characteristics and application of emissions after-treatment device of the exhaust gas recirculation and selective catalytic reduction and so on currently at home and abroad,furthermore giving prospect of diesel after-treatment technology to meet ultra-low emission requirement in the future. |
