Description
Technical field
The utility model is related to a kind of silencer, and in particular to a kind of exhaust silencer with lambda sensor.
Background technology
Silencer is the important component on motorcycle, is discharged into after the waste gas that engine is discharged is carried out into cooling noise reduction process
In air, play a part of absorbing sound and lowering noise.With the development of motorcycle technology, electric controlled gas-compensation technology slowly instead of carburetion
Device fueling technology, electric controlled gas-compensation technology can control the air-fuel ratio of blender, oil consumption is reduced to a certain extent and improves tail gas
Discharge, lambda sensor can constantly detect the oxygen content in engine exhaust as the key sensor of electric controlled gas-compensation system, from
And the combustion case of engine is detected, and signal is fed back into controller, make burning more abundant, and combine on silencer
Catalytic converter, the tail gas of exclusion is met respective standard.
But the existing exhaust silencer with lambda sensor is limited due to its structure, the discharge of waste gas and changing effect compared with
Difference, does not reach corresponding discharge standard, therefore urgent need makes improvements.
Utility model content
In view of the presence of problem above, a kind of simple structure of the utility model offer, can reach the band oxygen of discharge standard again
The exhaust silencer of sensor.
The technical solution of the utility model is as follows：
A kind of exhaust silencer with lambda sensor, including blast pipe and muffler body, the blast pipe include first
Exhaust pipeline section and second exhaust pipeline section, second exhaust pipeline section with diameter greater than first exhaust pipeline section, set on the first exhaust pipeline section
It is equipped with lambda sensor, the junction of first exhaust pipeline section and second exhaust pipeline section is provided with catalytic converter fixing pipe, the catalysis
Catalytic converter is connected with converter fixing pipe, one end of second exhaust pipeline section is connected with catalytic converter fixing pipe, another
End is connected with muffler body.
Preferably, the first exhaust pipeline section includes inner tube and the outer tube being set in outside the inner tube, the inner and outer tubes
Between form toroidal cavity, the diameter with diameter greater than the outer tube of the second exhaust pipeline section.
Preferably, being provided with thread bush on the first exhaust pipeline section, the thread bush is located in inner and outer tubes, and
The outer wall of the outer tube is stretched out, the lambda sensor is arranged in the thread bush.
Preferably, the muffler body has the cylinder of section gradual change, fixation is provided with the outer surface of the cylinder
Journal stirrup, fixing hole is provided with the fixation journal stirrup.
By adopting the above-described technical solution, the utility model has the advantages that：It is simple structure, compact, pass through
Setting the discharge duct and lambda sensor of different-diameter makes mixed gas mix evenly, preferably catalysis is carried out to waste gas and is turned
Change, while noise is reduced, waste gas is reached corresponding discharge standard, substantially increase the reliability of silencer work.
Other advantages of the present utility model, target and feature will be explained in the following description to a certain extent
State, and to a certain extent, based on being will be apparent to those skilled in the art to investigating hereafter, or
Person can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be said by following
