As shown in Figure 1-Figure 3, air inlet pipe 2 is at least partially disposed in shell 1.Specifically, air inlet pipe 2 is suitable for and starts
Machine exhaust pipe is connected, and the exhaust gas from engine is conducted to progress tail gas clean-up in exhaust gas cleaner 100.
Escape pipe 3 is connect with shell 1, and it is logical that gas flowing is formed between the outlet 31 of escape pipe 3 and the import 21 of air inlet pipe 2
Road 4.Specifically, one end of escape pipe 3 links together with shell 1, and the other end of escape pipe 3 is connect with exhaust tail pipe of automobile
Together, wherein the exhaust gas from engine enters exhaust gas cleaner 100 from the import 21 of air inlet pipe 2, is flowed via gas
Channel 4 is discharged from the outlet of escape pipe 3 31.
Further, it with reference to Fig. 2, is provided in gas flow channel 4 for being flowed into from import 21 and from 31 outflow of outlet
The tail gas clean-up structure 5 that is purified of gas.Specifically, when exhaust gas is flowed into the tail gas clean-up knot in gas flow channel 4
When at structure 5, tail gas clean-up structure 5 can carry out catalyzed conversion to exhaust gas, and it is harmless to human body and environment to make exhaust gas conversion
Gas, later, it is inverted after gas from outlet 31 outflow exhaust gas cleaners 100 complete exhaust gas processing.
