Abstract
The utility model discloses a motorcycle exhaust silencer comprising an exhaust pipe connected with the waste gas exhaust port of the engine, a silencing pipe provided with waste gas purification catalysts. A waste gas purification catalyst device is further arranged between the exhaust pipe and the silencing pipe; the waste gas purification catalyst device consists of a front connecting pipe, a rear connecting pipe, a sealing plate, waste gas purification catalysts, a clamp, wherein, the front connecting pipe is connected with the air outlet port of the exhaust pipe; the rear connecting pipe is sleeved at the outer wall of the front connecting pipe; the sealing plate between the outer wall of the front connecting pipe and the inner wall of the rear connecting pipe; waste gas purification catalysts are arranged in the front connecting pipe; and the clamp is tightly sleeved the rear connecting pipe and the front connecting pipe. The utility model can effectively purify the waste gas emitted during the engine running all the time, so that the waste gas finally emitted into air by the motorcycle can meet the Euro III Emission Standard.
Description
Technical field
The utility model relates to a kind of exhaust muffler for motorcycle, relates in particular to a kind of silencing apparatus that can improve the motorcycle exhaust emission quality.
Background technique
Exhaust muffler for motorcycle is to be used for handling the motorcycle engine toxic emission, reduces the device of the noise of motorcycle engine generation.Exhaust silencer is formed by connecting by outlet pipe and hush tube, for the purifying engine exhaust gas discharged, usually in the hush tube waste-gas cleaning catalyst is installed, but need reaching certain temperature, the waste-gas cleaning catalyst just can play good catharsis, the waste-gas cleaning catalyst that is installed in the hush tube is far away from exhaust opening of engine, early stage in engine operation, the temperature of the waste gas of position can not be increased to the temperature of catalyst energy proper functioning rapidly in the silencing apparatus of catalyst place, make catalyst carry out effective purified treatment to the waste gas that motor is discharged, thereby make this exhaust silencer relatively poor, can not satisfy EUROIII Emission Standard in the exhaust emission quality of the starting stage of engine operation.
The model utility content
The utility model is in order to overcome the deficiencies in the prior art, a kind of exhaust muffler for motorcycle that can make motorcycle engine waste gas reach EUROIII Emission Standard to be provided.
Technological scheme:
The purpose of this utility model is achieved in that a kind of exhaust muffler for motorcycle, comprise the outlet pipe that is connected with the engine exhaust relief opening, the hush tube that the waste-gas cleaning catalyst is installed, also be provided with a waste-gas cleaning catalyst device between wherein said outlet pipe and the hush tube.
Waste-gas cleaning catalyst device of the present utility model is by forming with give vent to anger preceding connecting tube that port is connected, the waste-gas cleaning catalyst that is provided with in the sealing gasket, preceding connecting tube between back connecting tube, preceding connecting tube outer wall and the back connecting tube inwall of connecting tube outer wall before being socketed on, the clip that is locked back connecting tube and preceding connecting tube of outlet pipe.
The utility model further design is that the necking end of preceding connecting tube and the outlet pipe port of giving vent to anger joins, and the necking end of back connecting tube and hush tube air inlet port join; Before connecting tube flared section and back connecting tube flared section relative socket, the back connecting tube flared section preceding connecting tube flared section partly that is locked, preceding connecting tube flared section is locked by clip with the position of the relative socket of connecting tube flared section afterwards.
In addition, the waste-gas cleaning catalyst is cellular cylindrical body, and the waste-gas cleaning catalyst communicates with the back connecting tube; Sealing gasket is a graphite pads.
Owing to adopted technological scheme described in the utility model, in hush tube and between hush tube and the outlet pipe, all be equipped with the waste-gas cleaning catalyst.Start working the stage at motor, the exhaust gas temperature that motor is discharged reaches the operating temperature of the waste-gas cleaning catalyst between hush tube and the outlet pipe, thereby makes the waste gas at engine start initial stage obtain effective purified treatment; And in engine operation after a period of time, the exhaust gas temperature at the waste-gas cleaning catalyst place between hush tube and the outlet pipe is too high and the waste-gas cleaning Processing capacity is reduced, but the exhaust gas temperature at the waste-gas cleaning catalyst place in the hush tube reaches its operating temperature, so waste gas is carried out effective purified treatment.The utility model makes motorcycle finally be discharged into airborne waste gas and reaches EUROIII Emission Standard the effective purified treatment of engine operation toxic emission all the time.

Embodiment
Embodiment
As shown in Figure 1 and Figure 2, the exhaust muffler for motorcycle of present embodiment, comprise the outlet pipe 1 that is connected with the engine exhaust relief opening, the hush tube 2 that the waste-gas cleaning catalyst is installed, wherein between outlet pipe 1 and hush tube 2, also be provided with a waste-gas cleaning catalyst device 3.
Waste-gas cleaning catalyst device 3 by with outlet pipe 1 give vent to anger preceding connecting tube 4 that port is connected, be provided with in the graphite pads 6, preceding connecting tube 4 between back connecting tube 5, preceding connecting tube 4 outer walls and back connecting tube 5 inwalls of connecting tube 4 outer walls before being socketed on be cellular cylindrical waste-gas cleaning catalyst 7, connect be locked back connecting tube 5 and before the clip 8 of connecting tube 4 form, waste-gas cleaning catalyst 7 with after connecting tube 5 communicate.
As shown in Figure 2, the necking end of preceding connecting tube 4 and outlet pipe 1 port of giving vent to anger welds mutually, and the necking end of back connecting tube 5 welds mutually with hush tube 1 air inlet port; Preceding connecting tube 4 flared section and the relative socket of back connecting tube 5 flared section, back connecting tube 5 flared section be locked the part preceding connecting tube 4 flared section, preceding connecting tube 4 flared section are locked by clip 8 with the position of the relative socket of back connecting tube 5 flared section, are convenient to waste-gas cleaning catalyst 7 is changed at any time.
