Description
Technical field
The utility model relates to a kind of exhaust muffler for motorcycle.
Technical background
Exhaust muffler for motorcycle is the device that is used to handle the motorcycle engine toxic emission, to reduce noise and the toxic emission pollution on the environment that motor produces.Exhaust silencer is formed by connecting by outlet pipe and silencing apparatus, and in outlet pipe or silencing apparatus catalyst is installed.Catalyst is that the centre is cellular cylindrical body, is used for the purifying engine exhaust gas discharged, and it just can play good waste-gas cleaning effect in the time of must reaching uniform temperature at the waste gas of engine emission, and its catharsis reduces on the contrary when exhaust gas temperature is too high.
The catalyst of installing in the existing exhaust muffler for motorcycle or be installed in the outlet pipe, or be installed in the interior pipe of silencing apparatus.Be installed in the exhaust silencer in the pipe in the silencing apparatus for catalyst, because catalyst is far away apart from engine exhaust port, start working the stage at motor, the temperature of silencing apparatus position, catalyst place waste gas can not be increased to rapidly catalyst can proper functioning temperature, make catalyst carry out effective purified treatment, thereby make this exhaust silencer relatively poor in the start working exhaust emission quality in stage of motor to the waste gas that motor is discharged.Be installed in exhaust silencer in the outlet pipe for catalyst, because catalyst is nearer apart from engine exhaust port, start working the stage at motor, the temperature of outlet pipe position, catalyst place waste gas is higher, so can make catalyst get started the effect of purifying exhaust air, and not have the expense gas discharging of a time period without effective purified treatment.But, along with the work of motor long period, outlet pipe position, catalyst place exhaust gas temperature is too high, will cause the waste-gas cleaning ability of catalyst to reduce, the waste gas that motor is discharged can not get effective purified treatment, so the exhaust emission quality of this exhaust silencer is also relatively poor.
In the motorcycle using process, because working life that is far longer than catalyst working life of exhaust silencer, so often when exhaust silencer still can normally use, catalyst has been scrapped and can not normally have been used.Because existing exhaust silencer catalyst installed position tube and tube (outlet pipe and outlet pipe, or outlet pipe and silencing apparatus) between be to be connected as a single entity by welding, so the catalyst scrapped can not take out in the exhaust silencer and change, like this, owing to causing whole exhaust silencer, scrapping of catalyst scrap, and this moment, silencing apparatus did not also reach working life far away, so the structure of existing exhaust silencer has caused the significant wastage of resource.
The model utility content
Technical problem to be solved in the utility model provides a kind of exhaust muffler for motorcycle, makes the engine exhaust through its discharge can access more efficiently purified treatment, to promote the exhaust emission quality of motorcycle engine; Make retracting of catalyst in it change simple and convenient and install reliable simultaneously.
Exhaust muffler for motorcycle described in the utility model comprises the silencing apparatus with urceolus and interior pipe, and the outlet pipe that is connected with silencing apparatus, and catalyst is installed in exhaust silencer, and described catalyst is installed in respectively in the interior interior pipe with silencing apparatus of outlet pipe; Outlet pipe is being welded with flange plate with the silencing apparatus connecting end, silencing apparatus with the urceolus of outlet pipe connecting end and interior pipe on be welded with flange plate with tapped hole, silencing apparatus and outlet pipe are connected as a single entity with screw by two flange plate; Outlet pipe is divided into two sections from its stage casing, and two sections outlet pipes are connected as a single entity with bolt by the flange plate that is arranged on its port, and the catalyst in the described outlet pipe is installed in wherein in the one section outlet pipe and another section outlet pipe connecting port.
Pipe has size two footpath sections in described, and described catalyst is positioned at the big footpath section of pipe, and between the seal ring between size section jointing place, two footpaths and two flange plate, thereby realize that catalyst installation in the pipe in silencing apparatus is spacing.
One of them flange plate that is arranged on two sections outlet pipe ports is weldingly fixed on wherein one section outlet pipe port, the endoporus of this flange plate is a step hole, another flange plate is sleeved on another section outlet pipe port, and this port is welded with protruding circle, protruding circle can stop the flange plate that is sleeved on this port, it can not be deviate from from outlet pipe from this port, this protruding circle is arranged in described flange plate inner bore of step and its Spielpassung, and is provided with seal ring between the step end face of protruding circle end face and this inner bore of step.
Be installed in catalyst in the outlet pipe port between described seal ring and the back-up ring that is weldingly fixed in the outlet pipe port, thereby the installation of realization catalyst in outlet pipe is spacing.
The utility model in outlet pipe and the interior Guan Zhongjun of silencing apparatus catalyst is installed, start working the stage at motor, because the catalyst that is installed in the outlet pipe is nearer apart from engine exhaust port, the waste gas that motor is discharged is higher in the temperature at this catalyst place, thereby makes this catalyst can carry out effective purified treatment to waste gas at the engine start initial stage; And in engine operation after a period of time, when catalyst place exhaust gas temperature in the outlet pipe too high and when causing this catalyst that the waste-gas cleaning Processing capacity is reduced, the temperature that is installed in catalyst place waste gas in the interior pipe of silencing apparatus raises, and the catalyst in the pipe can carry out effective purified treatment to waste gas in the silencing apparatus thereby make.So the utility model exhaust silencer begins to start in the entire work process that finishes to operation at motor, all can carry out effective purified treatment, thereby make the exhaust emission quality of motorcycle engine be able to further lifting with this kind exhaust silencer to the waste gas that motor is discharged.
Because big displacement motorcycle engine exhaust gas discharged temperature is higher, the mounting point of catalyst can be far away apart from engine exhaust port in the outlet pipe, can satisfy the required temperature of catalyst proper functioning too,, be suitable for the motorcycle engine of big discharge capacity so catalyst is installed in the outlet pipe stage casing.
Because connecting end at outlet pipe and silencing apparatus, and two sections outlet pipe ports are provided with flange plate, by flange plate with screw with outlet pipe and silencing apparatus, and two sections outlet pipes are connected as one with bolt, make outlet pipe and silencing apparatus, and two sections outlet pipes are easy to dismounting, thereby are convenient to the dismounting and change of catalyst in the exhaust silencer.When catalyst is scrapped, only need to change catalyst, exhaust silencer still can continue to use, so can not cause the waste of resource.
Cooperating between two sections protruding circles in outlet pipe port and the endoporus can conveniently be located two sections outlet pipes, is beneficial to the connection of two sections outlet pipes, increased by reliability and intensity that two flange plate connect simultaneously.Catalyst is therein in one section outlet pipe port, and at seal ring and be weldingly fixed between the back-up ring in the outlet pipe port, can make catalyst realize reliable the installation in outlet pipe; And the catalyst in the silencing apparatus in the pipe can be realized the reliable installation of catalyst in silencing apparatus equally between the seal ring between interior pipe size section jointing place, two footpaths and two flange plate.
