摘要
以某型防爆柴油机为例,对其进行加装废气处理水箱前后的外特性和十一工况对比试验,测出防爆柴油机输出扭矩、输出功率与十一工况下废气中主要成份CO、NO_X及HC含量、排气温度与油耗率,从而得出废气处理水箱对防爆柴油机动力性、排放特性与经济性的影响。测试结果显示:加装废气处理水箱后,动力性有所降低,在最大扭矩处,输出扭矩和输出功率均下降2.3%;CO排放量在高负荷工况下有所增加,最大增幅为24.9%;_排放有很大的改善,最大排放降幅为19.5%;HC排放量变化不大;排气温度不高于60℃,降温效果显著;油耗率最大增加4.6%,经济性下降。
Take a certain type of explosion-proof diesel engine as an example, The comparative test of the external characteristics and 11 working conditions before and after installing the waste gas treatment tank was carried out, The output torque, output power and CO, NO_X and HC contents, exhaust temperature and fuel consumption of the main components of the exhaust gas under the condition of 11 were measured, Therefore, the influence of waste gas treatment tank on the dynamic performance, emission characteristics and economy of explosion-proof diesel engine is obtained. Test results show： After installing the waste gas treatment tank, the dynamic performance is reduced, and at the maximum torque, the output torque and output power are both decreased by 2.3%. CO emissions increased at high load conditions, with a maximum increase of 24.9%. NO_X emissions have improved significantly, with a maximum emission reduction of 19.5%. HC emissions did not change much; Exhaust temperature is not higher than 60 ℃, the cooling effect is remarkable; The fuel consumption rate increased by 4.6% and the economy decreased.
