Description
Technical field
The utility model relates to a kind of catalyst mounting structure of motorcycle.
Background technique
At present, the catalyst of known motorcycle be installed on silencing apparatus or with bend pipe that silencing apparatus connects in, following several method is arranged:
One, two catalyst of method all are welded in silencing apparatus cavity inside, bend pipe and the welding of silencing apparatus cavity.Because catalyst is welded in the cavity, when bad damages appearred in silencing apparatus, catalyst can not take out and continue use, causes the waste of resource, makes the waste material cost of silencing apparatus be higher than the cost of silencing apparatus own far away.
Method two, a catalyst are welded in the noise elimination cavity, and another catalyst is positioned over the bend pipe afterbody, utilizes graphite grazing, clip connected.The catalyst of pipe bent position can take out, reduced the waste material cost effectively, catalyst damages at noise elimination cavity and still can not remove when bad in the noise elimination cavity, and clamp band type connects makes the silencing apparatus reliability reduce, carbon seal ring causes silencing apparatus gas leakage because of the rhegma of rocking of joint behind the use certain hour, increases the pollution to environment, must often change carbon seal ring, and this kind structure is changed the carbon seal ring inconvenience.
Method three, catalyst is welded in the catalyst thimble assembly fixing, utilizes bolton on bend pipe, during installation the catalyst assembly is stretched in the noise elimination cavity, bend pipe and cavity clip connected utilize carbon seal ring to seal.Two catalyst of this kind structure all can take out, and have avoided the increase of catalyst to silencing apparatus waste material cost fully, but because of catalyst and the welding of catalyst cover pipe assembly, catalyst lost efficacy to be needed to change and must change together with the catalyst sleeve pipe, and the catalyst cleaning is inconvenient.Also there is same defective in its clamp connection type with method two.
In addition, preceding two kinds of methods all can be stopped up the catalyst mesh because of the carbon distribution reason in the car load using process, cause the exhaust of motor not smooth, thereby the decline that brings engine power causes great influence to the power performance of car load.Must solve the problem (general about a year) that carbon distribution brings by changing silencing apparatus.Must change silencing apparatus its working life that makes silencing apparatus not reach, and causes the rapid increase of cost of silencing apparatus and the waste of resource.Though method three has solved above problem, catalyst must be changed together with its sleeve pipe, cost height, inconvenience; And the unreliable of clip connected brings noise pollution to surrounding environment, and directly the gas of discharging also pollutes atmosphere.Client must often change carbon seal ring, makes troubles to client.
