柴油/聚甲氧基二甲醚混合燃料匹配催化型颗粒捕集器的排放特性研究
Experimental Study on Emission Characteristics of Diesel/Polymethoxy Dimethyl Ether Mixed Fuel Matched Catalytic Diesel Particulate Filter
摘要
Abstract
Emission characteristics of a diesel engine fueling diesel/polymethoxy dimethyl ether(PODE)blends was investigated before and after a catalytic diesel particulate filter(CDPF).CDPF filtration efficiency and the effect of PODE addition on the changes in NOx,CO2,and particulate emissions at the front and rear ends of the CDPF were investigated and analyzed.The results showed that the addition of PODE improved the filtration efficiency of CDPF for particulate matter,and the average filtration efficiency of CDPF increased by 3.6%when D90P10(90%diesel+10%PODE by volume)was used.CDPF filtration efficiency for the nucleation mode was lower than 86.39%,and that for the accumulation mode was higher than 91.32%,and that for the nucleation mode was lower than that for the accumulation mode.CDPF filtration efficiencies for particulate matter of different particle sizes are different and increase with the increase of particle sizes.For both fuels,the geometric mean diameter(GMD)of the particulate matter after passing through the CDPF and the NOx emissions decrease,and CO2 emissions increase.关键词
