Exhaust gas dispersion device of catalyst performance test device for purification of exhaust gas of automobile

摘要

the design of the automobile exhaust purification catalyst performance test of exhaust dispersion device on the catalytic performance in the examination room, the chamber is installed in the support plate of the center is blocked, the center around the ucc54ubc84 is installed, and each chamber. only when the exhaust gas in the exhaust gas in the central part of the mouth is in, hit the pipe in the direction of the change in taper pipe on flow of exhaust gas and to be with each other, and the formation of the eddy current and the lag phenomenon, the phenomenon of the amount of exhaust gas to a catalyst in the chamber of the device not to enter because of catalyst performance accurately, compared to the limit.therefore, the design of exhaust pipe installed on the catalytic performance of the catalyst is in the room of the chamber supporting plate in the middle of the exhaust cone to cone fleet (vertex) in the exhaust pipe with a conical coil (vertex) in the exhaust pipe to the design the distribution of women in the various chamber to exhaust is equal as far as possible in each chamber, the distribution of the catalytic performance in the condition of the test to be able to accurately measure the performance of the catalyst can be uc788uac8c.
