Measurement of Diesel Particulate Emission By a Partial Flow Dilution Tunnel-Examination of Stability of Exhaust Gas Split Ratio
Published July 14, 1992 by Society of Automotive Engineers of Japan in Japan
A venture type partial flow dilution tunnel has already been developed to measure the diesel particulate. In this paper, the stability of exhaust gas split ratio during the diesel 13 mode test in Japan is examined using a newly developed automatic controller of the split ratio. As results, it can be clear that the exhaust muffler is necessary to stabilize the split ratio and also the deviations of gas split ratio is with ±3% for each mode of the D13 mode test.
