摘要
重点研究Pt/Pd/Rh堇青石催化剂对降低柴油机NOx排放的影响,并在一台4100Q柴油机上进行了试验研究。研究结果表明,该类型催化转化器具有较好的稳定性,对发动机的燃油经济性影响不大,但易受碳烟和SOF的影响。
The objective of the study is to gain understanding the factors which would affect NOx reduction in diesel for use of Pt/Rh/Pd catalyst. In this paper, a number of tests were conducted on a 4100Q,DI diesel. It shows that this kind of precious metal catalytic converter has good endurance ability and little side effect on the fuel economy. However, the catalyst can be covered easily by soot and soluble organic fractions （SOF）.
