Abstract
The utility model provides an automobile exhaust pipe, which belongs to the field of automobile parts, and solves the problem that the normal operation of an engine is affected due to the fact that the return pressure of the existing automobile exhaust pipe is not balanced. The automobile exhaust pipe comprises a left exhaust pipe and a right exhaust pipe, wherein a communication part used for connecting the left exhaust pipe and the right exhaust pipe and communicating air pressure in the left exhaust pipe and the right exhaust pipe is arranged in the middle of the left exhaust pipe and the right exhaust pipe. By arranging the communication part, the gas in the left exhaust pipe and the right exhaust pipe can be circulated, so that the air pressure is equal, the return pressure is further balanced, and the influence on the operation condition of the engine due to different return pressures is avoided.
Description
Technical field
The utility model belongs to the auto parts machinery field, relates to a kind of automobile exhaust pipe, the automobile exhaust pipe that particularly a kind of air outlet air pressure is balanced.
Background technique
Outlet pipe is an exhaust component very common on the automobile, and its suction port inserts the gas of discharging from motor, and discharges from the air outlet of outlet pipe.Existing automobile exhaust pipe generally includes left bank tracheae and right outlet pipe, and their the two independence has four suction ports usually separately, receives the gas of discharging from motor respectively.The gas atmosphere of discharging from motor is normally consistent; But during through two outlet pipes; Because the two difference in design produces different back pressure in the time of can causing gas in two outlet pipes, to circulate, two kinds of different back pressure cause air pressure unbalanced; Can influence the exhaust situation and the power performance of motor conversely, even influence the ride quality of whole automobile.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of gas balanced automobile exhaust pipe of back pressure in left and right two outlet pipes of discharge.
The purpose of the utility model can realize through following technical proposal: a kind of automobile exhaust pipe, comprise left bank tracheae and right outlet pipe, be provided with at said left bank tracheae, right outlet pipe middle part connect the two, interconnecting part that the air pressure in the two is communicated.
In above-mentioned automobile exhaust pipe, said interconnecting part makes whole automobile exhaust pipe become H shape for connecting the pipeline of said left bank tracheae and right outlet pipe.
In above-mentioned automobile exhaust pipe, respectively offer a hole on the sidewall of said left bank tracheae and right outlet pipe in opposite directions, and alignment of said two holes and connection, form the interconnecting part that is communicated with said left bank tracheae and right outlet pipe, make whole automobile exhaust pipe become X-shaped.
In above-mentioned automobile exhaust pipe, said left bank tracheae and right outlet pipe have four suction ports respectively.
Compared with prior art, the gas of left bank tracheae and right outlet pipe can be circulated each other, thereby air pressure equates that then back pressure is also balanced, avoid back pressure different and have influence on the operation conditions of motor through interconnecting part.
Description of drawings
Fig. 1 is the plan view of the utility model first embodiment's automobile exhaust pipe;
Fig. 2 is the partial 3 d figure of the automobile exhaust pipe of Fig. 1;
Fig. 3 is the sectional drawing of part shown in Figure 2;
Fig. 4 is the plan view of the utility model second embodiment's automobile exhaust pipe.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, the automobile exhaust pipe of the utility model comprises left bank tracheae 1 and right outlet pipe 2, and left bank tracheae 1 respectively has four suction ports 4 with right outlet pipe 2, is used for receiving the gas of discharging from motor.
Left and right outlet pipe is drawn close at the middle part each other, and until contact and connect as a wholely, its structure is specifically as shown in Figure 2, becomes approximate X-shaped.The two contacted part; Be to offer on the madial wall by left bank tracheae 1 in opposite directions the sidewall with it of a hole 3, right outlet pipe 2 also to offer identical hole 3; As shown in Figure 3; 3 alignment of two holes also weld together the mural margin in two holes 3, make the interconnecting part that gas communicates in the left and right outlet pipe thereby form.
Adopt this structure; Then the gas in left bank tracheae 1 and the right outlet pipe 2 is through above-mentioned hole the time; Can take place to mix each other and exchange; And the air pressure of the two also can reach balanced, guarantees that the back pressure in the left bank tracheae 1 is consistent with back pressure in the right outlet pipe 2, thereby can not have influence on the operation conditions of motor.
In the present embodiment, the size in hole 3 is confirmed according to the size of actual pipeline and the speed of engine exhaust, to confirm suitable gas exchange speed.Simultaneously, left and right outlet pipe is drawn close until the corner dimension of contact distance length with this part and suction port from beginning each other, all can design according to actual needs and adjustment.
In another embodiment; As shown in Figure 4; Automobile exhaust pipe comprises left bank tracheae 1, right outlet pipe 2 and connecting tube 5; This connecting tube 5 is one section straight pipe, and its two ends directly are communicated with left bank tracheae 1, right outlet pipe 2, thereby constitute to connect both and interconnecting part that the gas in them can be circulated each other.
Can be known that by Fig. 4 this embodiment's automobile exhaust pipe is H shape, its structure is simpler relatively than a last embodiment, is more conducive to manufacture and reduce cost; And thereby two outlet pipes more can be convenient to abundant mixing gradually near guaranteeing that gas can mix together gradually among the last embodiment, thereby make back pressure balanced.
Certainly; The automobile exhaust pipe of the utility model is not limited in above-mentioned two embodiments and the described structure of accompanying drawing; Other various deformation can also be arranged,, two outlet pipe internal air pressure equilibriums and back pressure are equated thereby make the interior gas of two outlet pipes to circulate as long as automobile exhaust pipe has left and right outlet pipe and the two middle part is communicated with through variety of way; Promptly constitute the interconnecting part of the utility model, then such automobile exhaust pipe all belongs within the protection domain of the utility model.
Therefore, specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as outlet pipe, connection, back pressure morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
