Off-Engine Control Technologies for Exhausting Particle From Vehicle Diesel Engines

The developing background of the off engine control technologies was described briefly. The common measures to control particle emission such as, diesel engine exhaust particle filter, the technique of engine emission control with plasma, the cyclone filtration technology for reducing engine particulate emissions, the oxy catalyst and the combined technology used to control vehicle engne emission were introduced emphatically. The problems lying in each measure were analyzed in accordance with Chinese specific conditions. The analysis showed that diesel engine exhaust particle filter and the combined technology are the better ways to control exhaust particle from vehicle diesel engine.
