The utility model discloses a kind of front exhaust pipe, wherein, including：Body and muff, body are individual layer tube wall, and one end of body connects the manifold of engine, other end connection preprocessor；Muff is fixed and is set on body.Body is individual layer tube wall, can mitigate the weight of front exhaust pipe, helps to reduce the quality of vehicle；By the way that muff is fixed on outside body, can help front exhaust pipe carry out insulation with it is heat-insulated, muff is simple to manufacture, cost is relatively low.
Description
Technical field
The utility model is related to technical field of automobile parts, more particularly to a kind of front exhaust pipe.
Background technology
With the raising of environmental protection requirement, country is to the emission request more and more higher of vehicle exhaust, it is necessary to engine
Waste gas is post-processed.Harmful substance in tail gas is mainly comprising nitrogen oxides, carbon monoxide, hydrocarbon, particle etc., meeting
Tremendous influence is caused to human body and environment, it is necessary to be allowed to become nontoxic material by chemical reaction.For reduction discharge, arranging
Increase preprocessor in gas system to be chemically treated tail gas, chemical reaction just can will fully be divided at a higher temperature
Solve harmful substance.In the prior art, in manifold to the front exhaust pipe that must have one section of guiding tail gas between preprocessor,
Therefore the thermal loss of front exhaust pipe is reduced, the content of pollutant in final vehicle discharge tail gas will be directly influenced.Meanwhile, by
In the engine of maximum discharge requirement, delivery temperature is higher, therefore conventional exhaust pipeline surface temperature is higher, easily to zero, periphery
Part causes hot evil, using air gap pipes, be effectively isolated heat, reduces blast pipe surface temperature, reduces hot evil.As schemed
Shown in 1, the ＇ of front exhaust pipe 1 includes the ＇ of the first tube wall 11 of outer layer and the ＇ of the second tube wall 12 of internal layer, due to needing two layers of blast pipe
Weld together, cause manufacture difficulty big, in addition, double-decker adds the weight of front exhaust pipe, cause on complete vehicle weight
Rise.
Utility model content
The purpose of this utility model is to solve the problem of front exhaust pipe manufacture is complicated, weight is larger.
The utility model provides a kind of front exhaust pipe, wherein, including：
Body, the body is individual layer tube wall, and one end of the body connects the manifold of engine, located after other end connection
Manage device；
Muff, the muff is fixed and is set on the body.
Preferably, the muff is strip corrugated plate shape, and the muff curling is fixed on the outside of the body.
Preferably, the front exhaust pipe also includes clip, and the clip is set on the muff.
Preferably, the quantity of the clip is multiple, is equidistantly set on the muff.
Preferably, the muff forms a confined space between clip described in each two.
Preferably, the muff uses aluminum foil material.
The beneficial effects of the utility model are：
The utility model provides a kind of front exhaust pipe, including：Body and muff, body are individual layer tube wall, muff
Fixation is set on body.Body is individual layer tube wall, can mitigate the weight of front exhaust pipe, helps to reduce the quality of vehicle；
By the way that muff is fixed on outside body, can help front exhaust pipe carry out insulation with it is heat-insulated, muff is simple to manufacture, cost
It is relatively low.
Brief description of the drawings
Fig. 1 is the schematic diagram of front exhaust pipe of the prior art；
The schematic diagram for the front exhaust pipe that Fig. 2 provides for the utility model embodiment；
Fig. 3 is the schematic diagram after muff deploys.
Reference is as follows：
1 ＇-front exhaust pipe, 11 ＇-the first tube walls, 12 ＇-the second tube walls, 1- front exhaust pipes, 11- bodys, 12- muffs,
13- clips.
Embodiment
Embodiment of the present utility model is described below in detail, the example of embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the utility model, and can not be construed to limitation of the present utility model.
As shown in Figure 2 to Figure 3, the utility model provides a kind of front exhaust pipe 1, wherein, including：Body 11 and muff
12, body 11 is individual layer tube wall, and one end of body 11 connects the manifold of engine, other end connection preprocessor；Muff is consolidated
Surely it is set on body 11.Body 11 is individual layer tube wall, can mitigate the weight of front exhaust pipe 1, helps to reduce complete vehicle quality；
By the way that muff 12 is fixed on outside body 11, can help front exhaust pipe 1 carry out insulation with it is heat-insulated, muff 12 manufactures letter
Single, cost is relatively low.
As shown in figure 3, further, muff 12 is strip corrugated plate shape, the curling of muff 12 is fixed on body 11
Outside.The expansion of muff 12 is in strip, and with ripple projection, by the way that muff 12 is crimped, can be fixed on muff 12
On body 11, the muff 12 after curling due to wavy projection, compared to plane radiating, is added and connect with air
Contacting surface is accumulated, and then can improve the radiating efficiency of front exhaust pipe 1.
Further, front exhaust pipe 1 also includes clip 13, and clip 13 is set on muff 12.Fixed by clip 13
Muff 12, can be easy for installation and removal.
Further, the quantity of clip 13 is multiple, is equidistantly set on muff 12.Because the curling of muff 12 is solid
It is scheduled on body 11, sets multiple clips 13 that muff 12 is fixed, it is to avoid the stress deformation of muff 12, reduces body 11
Heat release, improve front exhaust pipe 1 thermal insulation.
Further, muff 12 forms a confined space between each two clip 13, and confined space can reduce heat
Gas is dispersed into outside, can improve the heat insulation effect of front exhaust pipe 1.
Further, muff 12 uses aluminum foil material.Stored using the muff 12 of aluminum foil material is convenient, and weight
It is relatively light, it reduce further the weight of vehicle.
Construction of the present utility model, feature and action effect is described in detail according to the embodiment shown in schema above, with
Upper is only preferred embodiment of the present utility model, but the utility model is not to limit practical range shown in drawing, every according to this
The change that the conception of utility model is made, or the equivalent embodiment of equivalent variations is revised as, still without departing from specification and diagram institute
, all should be in protection domain of the present utility model during the spirit covered.
