Description
[technical field]
The invention relates to a kind of secondary air lead-in device of vehicle.
[background technique]
The power resources of vehicle are by outside fresh air and fuel oil being mixed formation oil gas, oil gas being imported fire generation power in the engine E again.Because firing also of engine E can't be burnt oil gas completely, and can be with part unburned oil gas completely, along with the exhaust system of engine E is discharged waste gas, this exhaust system is made of the air outlet flue Ea of engine E and outlet pipe M, this waste gas is owing to contain the oil gas of part, thereby caused the pollution of engine E institute exhaust gas discharged to improve, and then caused environmental issue.So vehicle manufacturer, can on engine E exhaust system, import secondary air, as shown in Figure 1, the importing of this secondary air, mainly be the air in the external world to be imported by an air pipe P1, filter through secondary air jar C, at least has a filter element in this secondary air jar C, secondary air after filtering is again by pneumatic tube P2, in an one-way valve V imports outlet pipe M (also secondary air can be imported in the air outlet flue Ea), this one-way valve V can prevent that the waste gas in the outlet pipe M from entering in the secondary air jar C, this secondary air can still be the state of high temperature by the waste gas that is expelled to outlet pipe M from engine E after importing outlet pipe M, and secondary air can make the waste gas that engine E is discharged by this, in outlet pipe M, do burning once more, can reduce the pollution of engine E institute exhaust gas discharged.Above-mentioned by on outlet pipe M, importing secondary air, Gu effectively can reduce the exhaust emission pollution of vehicle.But, this secondary air can be imported into normally or can secondary air jar C operate normally, depend on the setting of secondary air introducing port entirely.
The configuration of the vehicle secondary air introducing port of commonly using, with the all-terrain vehicle is example, the configuration that this all-terrain vehicle A secondary air imports, as shown in Figure 2, be on the mounting plate Eb of engine E1, connect and establish an one-way valve V1, this one-way valve V1 can prevent that the waste gas of engine E1 from entering in the secondary air jar C1, this one-way valve V1 is connected with secondary air jar C1 by pneumatic tube P3, the termination in addition of secondary air jar C1 is provided with air pipe P4, the front end of this air pipe P4 has introducing port P41, and the introducing port P41 of this air pipe P4 is on the support F of drag fender T below before being installed in.The configuration of the above-mentioned all-terrain vehicle A secondary air introducing port P41 that commonly uses, make this introducing port P41 expose fully in atmosphere, and this all-terrain vehicle A, the main region of using is seashore or mountain area etc., these zones are the region than juicy and dust, therefore caused dust or water following air easily by introducing port P41, in air pipe P4 enters secondary air jar C1, and make member losses of function such as filter element in the secondary air jar C1, and then make secondary air jar C1 damage can't to operate, cause secondary air normally to be imported in the outlet pipe M or done the action of secondary combustion in the air outlet flue Ea.
Therefore, known secondary air imports arrangement, can't effectively make secondary air jar C1 have dustproof and water proofing property, and then the effect of secondary air can't effectively be brought into play, therefore how to provide one to make secondary air jar C1, have the secondary air lead-in device of preferable dustproof and water proofing property, real is a vehicle manufacturing industry big problem extremely to be solved.
