A particulate separation system that can be used to study the characteristics of the diesel particulate agglomeration and cyclone s eparation is developedIt includes a diesel particulate agglomerator and a cycl one separator mainlyA preliminary investigation on the cyclone separation tech nology for controlling the exhaust particulate from a diesel engine is conducted The experimental results show that the diameter distribution of the diesel par ticulate is changed after they pass through the agglomerator,almost 30%～40% o f the particulate agglomerated from less than 10μm to larger than 10μm ,this change contributes to trap diesel particulateWith this system installed on the exhaust pipe of a singlecylinder engine,the particulate separation effi ciency is around 40%～60% under typical engine running conditionThe backpres sure of this system is less than 5 kPa on full load condition,much less than tha t of other methods of particulate filtrationThis technology has the possibilit y to open a new prospect for particulate reduction because of its simplicity,rel iability and low resistance
