Abstract
The utility model relates to an automobile silencer comprising a shell body, silencing tubes and silencing partition plates, wherein two ends of the shell body are sealed, the silencing partition plates are arranged parallel to end covers of the shell body, the silencing tubes penetrate through the shell body and the silencing partition plates, and decompressing silencing holes are arranged in portions penetrating through the shell body and the silencing partition plates of the silencing tubes. The silencing partition plates and the silencing tubes penetrating through the shell body are arranged, so gas flows in cavity bodies separated by the silencing partition plates through the decompressing silencing holes and air-communicating silencing holes, collisions lower sound energy, and silencing effects are improved. The air enters the silencing tube, and pressure in a channel disperses into the shell body through the decompressing silencing holes so that air exhausting is smooth, oxygen intake of an engine is increased, power performance of the engine is improved, burning of the engine is sufficient, unnecessary oil consumption is saved, carbon deposition is reduced, and service life of the engine is prolonged.
Description
Technical field
The utility model relates to a kind of auto parts machinery, specifically a kind of mobile muffler.
Background technique
The effect of mobile muffler is to reduce the noise that motor produces, and reduces vibration, improves the travelling comfort that automobile uses, protection of the environment.Existing baffler comprises enclosing housing and is connected to suction tude (being the outlet pipe of automobile) and the steam outlet pipe at enclosing housing two ends, is provided with silencing board in enclosing housing, is distributed with the bloop of collaborating at silencing board.The waste gas of discharging behind the engine combustion enters in the enclosing housing by suction tude, and after the noise reduction of collaborating by extended volume in enclosing housing and silencing board, reaches the effect of step-down, noise elimination, is discharged by steam outlet pipe at last.Because the suction tude in the baffler does not link to each other mutually with steam outlet pipe, and the gas that enters in the enclosing housing all will discharge to the external world by steam outlet pipe at last, this just will inevitably cause the exhaust of steam outlet pipe not smooth, the exhaust resistance of baffler is strengthened, and so that the needed back pressure of motor reduces, thus, both affected the sound deadening of baffler, power output to motor also can bring adverse effect, also can cause the increase of oil consumption.
The model utility content
The purpose of this utility model just provides a kind of mobile muffler, to solve the problem that existing mobile muffler exhaust resistance is large, fuel consumption is exported and strengthened to power that affect motor.
The utility model is achieved in that a kind of mobile muffler, comprise enclosing housing and the suction tude and the steam outlet pipe that are connected to described enclosing housing two ends, in described enclosing housing, be provided with silencing board, be distributed with the bloop of collaborating at described silencing board, described suction tude and described steam outlet pipe axially run through described enclosing housing, in described enclosing housing, also be penetrated with muffler, the outlet of described suction tude and the import of described muffler are connected by outside bend pipe, the outlet of described muffler and the import of described steam outlet pipe are connected by outside bend pipe, the described suction tude in described enclosing housing, be distributed with the decompression bloop on the tube wall of described muffler and described steam outlet pipe.
Described silencing board has two, is set in parallel in the described enclosing housing, and intersects vertically with described suction tude.
The working procedure of motor car engine and the relation of exhaust are: piston stroking upward needs exhaust decompression; Descent of piston needs exhaust back pressure.After this mobile muffler was installed, when descent of piston, outlet pipe can produce certain swirling recirculation flow back pressure, helped descent of piston; When the work of piston stroking upward, outlet pipe, can produce certain pressure in the pipeline, refuel greatlyr, pressure is larger; Reciprocal three times decompression noise reduction in the oiling decompression, can increase the air inlet oxygen content of motor, and engine power is strengthened, sufficient combustion, thus the generation of minimizing carbon on engine prolongs the working life of motor, and can realize the purpose of fuel-economizing; In the time of three decompression expansions, also played the effect of three noise reductions.The utility model can produce the effect of decompression, noise reduction and rotation back pressure when outlet pipe is worked.
The utility model both can improve erasure effect, made exhaust more smooth and easy, can increase simultaneously the air inlet oxygen content of motor, promote the power performance of motor, make the burning of motor more abundant, saved unnecessary oil consumption, reduce carbon distribution, prolong the working life of motor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, suction tude, 2, end face, 3, enclosing housing, 4, silencing board, 5, the decompression bloop, 6, the bloop of collaborating, 7, muffler, 8, steam outlet pipe.
Embodiment
As shown in Figure 1, the utility model comprises the enclosing housing 3 of a circle or elliptic cross-section, in enclosing housing 3, be provided with two silencing board 4(quantity increase and decrease can be arranged), silencing board 4 be arranged in parallel with the end face 2 of enclosing housing 3 both sides, is densely covered with the bloop 6 of collaborating at every silencing board 4.In enclosing housing 3, be connected to three pipes that axially run through: a suction tude 1, a muffler 7 and a steam outlet pipe 8.The two ends of three pipes are connected on the end face 2 of enclosing housing 3 both sides, and, the import of the outlet of suction tude 1 right-hand member and muffler 7 right-hand members is connected by the outside bend pipe on housing right side, the import of the outlet of muffler 7 left ends and steam outlet pipe 8 left ends is connected by the outside bend pipe in housing left side, forms thus a connecting tube of back and forth unrolling on enclosing housing 3.Silencing board 4 in the enclosing housing 3 intersects vertically with suction tude 1, and suction tude 1, muffler 7 and the tube wall of steam outlet pipe 8 in enclosing housing 3 are densely covered with decompression bloop 5.
Claims (2)
1. mobile muffler, comprise enclosing housing and the suction tude and the steam outlet pipe that are connected to described enclosing housing two ends, in described enclosing housing, be provided with silencing board, be distributed with the bloop of collaborating at described silencing board, it is characterized in that, described suction tude and described steam outlet pipe axially run through described enclosing housing, in described enclosing housing, also be penetrated with muffler, the outlet of described suction tude and the import of described muffler are connected by outside bend pipe, the outlet of described muffler and the import of described steam outlet pipe are connected by outside bend pipe, the described suction tude in described enclosing housing, be distributed with the decompression bloop on the tube wall of described muffler and described steam outlet pipe.
2. mobile muffler according to claim 1 is characterized in that, described silencing board has two, is set in parallel in the described enclosing housing, and intersects vertically with described suction tude.
