Research on the Full-Flow and Partial-Flow Dilution Sampling Systems for Exhaust Gas of Engine

Abstract:

This paper analyzes the principle of operation, the feature of systems, the contrast of advantages and disadvantages of the two different systems which are Full-flow dilution sampling system (FFDSS) and Partial-flow dilution sampling system (PFDSS).This paper researches the correlation of this two different systems and the ways of improving the correlation. Many researches show that the correlation of the PM's test is below 10%.The PFDSS can replace the FFDSS in the special case. Some detailed suggestions of improving the systems to meet the future requirements are presented in the last of this paper.
