This system can be used to accomplish the rea-l time data acquisition, measurement of particulate emission and control of basic transient operatin modes. eywords:diesel en ine; exhausted particulate; transient operatin condition; measurin technique , . , . 1984 , , EPA ; . 2000 10 1 , EURO , 1 , ET C . . , , , .
