Abstract
The utility model discloses an automobile exhaust pipe. The automobile exhaust pipe is characterized by comprising a main exhaust pipe which is connected with an automobile engine, a three-way catalyst device which is connected with the main exhaust pipe, a silencer which is connected with the three-way catalyst device and a first branching pipe and a second branching pipe which are connected with the silencer, wherein filter screens are installed in middle portions of the first branching pipe and the second branching pipe, and more than one hole is formed in heads of the first branching pipe and the second branching pipe. The automobile exhaust pipe has the advantages that by the aid of the arranged three-way catalyst device, harmful gases, such as CO and HC, which are exhausted in automobile tail gases are converted into harmless carbon dioxide, water and nitrogen through oxidation and reducing actions; by the aid of the arranged silencer, exhaust noises are reduced, flames and sparks in exhaust gases are eliminated, and the exhaust gases are emitted safely; by the aid of the arranged filter screens, some waste residues are left in the filter screens, so that only the filter screens are required to be changed, the structure is simple, and the installation is convenient.
Description
Technical field
The utility model relates to a kind of automobile exhaust pipe.
Background technique
In recent years, the urban motor vehicle increases very fast, incident traffic noise pollution environmental phenomenon also becomes increasingly conspicuous, automobile is noise pollution to the harm of environmental protection maximum, atmospheric pollution, and investigation shows, the Motor Vehicle noise accounts for 75.5% of city noise, along with the development of automotive energy-saving emission-reducing, require automobile to reduce noise, energy saving consumption.And the topmost noise of automobile is from the vent systems of automobile, and namely the motor vehicle exhaust emission noise in order to reduce the motor vehicle exhaust emission noise, satisfies the requirement of automobile environment-protection.。
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, and is easy for installation and have an automobile exhaust pipe that reduce to pollute and reduce noise.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of automobile exhaust pipe, comprise the main exhaust that connects motor car engine, and the ternary catalyzing unit of connection main exhaust, and the baffler of connection ternary catalyzing unit, and first branched pipe and second branched pipe of connection baffler, described first branched pipe and second branched pipe middle part are equipped with filter screen, and the head of described first branched pipe and second branched pipe is provided with more than one hole.
As optimized technical scheme, described baffler comprises throttle pipe, reflection tube and sound absorber, and described throttle pipe is connected with sound absorber with reflection tube successively.
As optimized technical scheme, be welded with contiguous block between described first branched pipe and second branched pipe.
The beneficial effect of the utility model automobile exhaust pipe is: 1, by set ternary catalyzing unit, thereby harmful gases such as the CO that vehicle exhaust is discharged and HC change harmless carbon dioxide, water and nitrogen into by oxidation and reduction; 2, by set baffler, make and reduce exhaust sound and eliminate flame and Mars in the waste gas, waste gas is discharged safely, 3, by set filter screen, make some waste residues stay filter screen, only need more slip over filter screen and get final product, it is simple in structure, and is easy for installation.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model automobile exhaust pipe.
Embodiment
Consult a kind of automobile exhaust pipe shown in Figure 1, comprise the main exhaust 1 that connects motor car engine, and the ternary catalyzing unit 2 of connection main exhaust 1, and the baffler 3 of connection ternary catalyzing unit 2, and first branched pipe 4 and second branched pipe 5 of connection baffler 3, described first branched pipe 4 and second branched pipe, 5 middle parts are equipped with filter screen 6, and the head of described first branched pipe 4 and second branched pipe 5 is provided with more than one hole 7.
Wherein, described baffler comprises throttle pipe 8, reflection tube 9 and sound absorber 10, and described throttle pipe is connected with sound absorber with reflection tube successively.
Be welded with contiguous block 11 between described first branched pipe 4 and second branched pipe 5.
The beneficial effect of the utility model automobile exhaust pipe is: 1, by set ternary catalyzing unit, thereby harmful gases such as the CO that vehicle exhaust is discharged and HC change harmless carbon dioxide, water and nitrogen into by oxidation and reduction; 2, by set baffler, make and reduce exhaust sound and eliminate flame and Mars in the waste gas, waste gas is discharged safely, 3, by set filter screen, make some waste residues stay filter screen, only need more slip over filter screen and get final product, it is simple in structure, and is easy for installation.
The above only is this practical embodiment, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
