| Abstract: | The measurement principle is introduced in the emission test of diesel vehicles and the defect is analysed in the loading, power scanning control, exhaust measurement control method about the LugDown test facilities. Based on the control requirements of the national standard and the working characteristics of LugDown test facilities, the improvement method is discussed in the power scanning performance, parasitic gliding performance, exhaust measurement process control, test gear selection and the initial scanning speed control etc. |
