| Abstract: | The objective of the study is to gain understanding the factors which would affect NO_x 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). |
