The Development of Diesel Engine Exhaust Particulate Filter

The diesel engine is widely used in light vehicle;after-treatment of particulate of diesel exhaust gas is becoming research hot spot.Particulate Filter is the most effective after-treatment method solving the diesel exhaust particulate pollution.Aimed at the current situation of DPF in domestic,the research status of filter material and the regeneration technologies of filter in recent years are discussed,and some favorable diesel exhaust particulate filters are introduced,which is combined with filter material and regeneration technologies.The research direction of DPF in the future is put forward.
