4D47Ti型柴油机排放试验

Test of 4D47Ti Model Diesel Engine Exhaust

从试验的角度分析了柴油机的活塞压缩比、燃烧室、喷油泵、增压器、喷油嘴偶件、中冷温度等参数对排放的影响;介绍了使4D47Ti型增压中冷柴油机排放达到欧Ⅱ标准所采取的措施。

This paper analyzes effects of the following parameters,such as the piston compression ratio,combustion chamber,injection pump,supercharger,injection nozzle coupling,medium-cooled temperature on exhaust from the angle of test.It also introduces measures adopted which make 4D47Ti model supercharged medium-cooled diesel engine exhaust reach to Europe Ⅱ standard.
