摘　　要：随着我国车辆排放标准的不断更新和执行,内燃调车机车的碳烟排放,已成为制约其正常生产作业的重要因素之一,为了研究碳烟排放的净化滤芯材料,基于实验测试,确定三种滤芯材料(泡沫镍,金属纤维毡、304不锈钢网)的碳烟过滤特性和阻力特性.实验表明,300目的 304不锈钢网净化效果最佳.With the constant updating and implementation of the vehicle emission standards in China,the soot emission of the diesel shunting locomotives has become one of the important factors which restrict normal production and operation.In order to study the filtration material for soot emission,soot filtration characteristics and resistance characteristics of three kinds of filtration material(foam nickel,metal fiber felt and 304 stainless steel mesh)were determined based on experimental tests.Results show that 300 mesh 304 stainless steel mesh has the best filtration effect.
