Description

A kind of adjustable type automobile exhaust pipe device

Technical field

The utility model relates to a kind of automobile component more particularly to a kind of automobile exhaust pipe devices.

Background technique

Auto industry is in development with rapid changepl. never-ending changes and improvements in society now, and people's lives increasingly be unable to do without automobile. The development of auto industry be it is various, wherein exhaust pipe is a part of engine exhaust system, and exhaust system mainly includes Exhaust manifold, exhaust pipe and muffler；And the general exhaust pipe device i.e. exhaust pipe that we say and muffler part.

And exhaust pipe device is whether should to fill muffler be always some to pursue high performance automobile players and be relatively entangled with A contradiction, if saying from the angle of noise be arranged muffler, thundering while the car is driving in this way Sound will control in the reasonable range of a comparison, and then noise reduction is also to lose a degree of power as cost. There are also automobile players in order to obtain highest power, and repacking eliminates muffler, although the kinaestheic in driving is more preferable A bit, but in some social contexts (residence district for example lived etc.), excessive exhaust pipe noise can become one again A troubling problem.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of structures, and unique, reasonable automobile exhaust pipe fills Set, can neatly Exhaust Pressure mode, to adapt to driver's need different in different occasions to dynamic mode and cancellation mode It asks.

In order to solve this technical problem, the technical solution adopted in the utility model is as follows:

A kind of adjustable type automobile exhaust pipe device, including exhaust pipe and muffler, the exhaust pipe include exhaust pipe master Pipeline and exhaust pipe secondary duct；The front end of the exhaust pipe main pipeline is connected to exhaust manifold, tail end connect exhaust outlet spray head；

The front end of the exhaust pipe secondary duct is connected to exhaust pipe main pipeline front, forms the first threeway of exhaust pipe trouble Mouthful；The rear end of the exhaust pipe secondary duct is connected to exhaust pipe main pipeline tail portion, forms the second threeway of exhaust pipe fork, institute Muffler is stated to be set in the exhaust pipe secondary duct；The row between first threeway fork and the second threeway fork The bending radius of curvature of tracheae main pipeline is greater than the bending radius of curvature of the muffier-in pipe；

String is equipped with electronic valve between first threeway fork and the second threeway fork on the exhaust pipe main pipeline, Control opening or closing for this section of exhaust pipe main pipeline.

Further, at first threeway fork exhaust pipe secondary duct and exhaust pipe main pipeline air inlet section angle No more than 90 degree.

Further, the caliber of the exhaust pipe secondary duct is less than the caliber of the exhaust pipe main pipeline.

The adjustable automobiles exhaust pipe device of the utility model dexterously passes through exhaust pipe main pipeline, secondary duct and electronics The combination of valve is arranged, so that motor vehicle operators realize on a trolley while having high dynamic mode and strong cancellation mode Air outlet duct system, and can neatly be switched according to different occasions, greatly meet driving for driving enthusiast Sail enjoyment.

The region of low noise is needed in conventional section or residence district etc. when driver travels, as long as described in control closing Electronic valve, automobile exhaust will be discharged into exhaust pipe secondary duct at the first threeway fork, so through exhaust pipe main pipeline leading portion The endpiece for entering exhaust pipe main pipeline through the first threeway fork after muffler section afterwards, is then discharged through exhaust outlet spray head.This Kind mode can obtain optimal erasure effect, and do not disturb residents low noise.

And when driver needs to enjoy high dynamic mode, as long as the electronic valve, automobile exhaust are opened in control It directly whole can be vented by exhaust pipe main pipeline, because the general caliber of exhaust pipe main pipeline can bigger and main pipeline bending Curvature can be bigger, so capacity and speed can be bigger, it will be bigger to the contribution of automobile power, automobile obtains more preferably power Performance, while can also have bigger exhaust noise.

When the electronic valve is opened, due to exhaust described between first threeway fork and the second threeway fork The bending radius of curvature of pipe main pipeline is greater than the bending radius of curvature of the muffier-in pipe, so exhaust pipe main pipeline direction Air drag is considerably lower, and exhaust nature can be discharged along exhaust pipe main pipeline, without entering exhaust pipe secondary duct；In order to more Be conducive to be vented, more preferably, the exhaust pipe secondary duct described in the position of first threeway fork and exhaust pipe main pipeline air inlet section Angle be not more than 90 degree, thus will not partially flow to exhaust pipe secondary duct naturally.

Detailed description of the invention

It is practical to this below in conjunction with attached drawing for the above objects, features, and advantages of the utility model can be clearer and more comprehensible Novel specific embodiment elaborates, in which:

Fig. 1 is the structural schematic diagram of the utility model adjustable type automobile exhaust pipe device.

In figure:

1, muffler 2, exhaust outlet spray head

3, electronic valve 100, exhaust pipe main pipeline

200, exhaust pipe secondary duct 101, the first threeway fork

102, the second threeway fork

Specific embodiment

The utility model is described in further detail below in conjunction with drawings and examples:

Fig. 1 shows a kind of adjustable type automobile exhaust pipe device, including exhaust pipe and muffler 1, the exhaust pipe packet Include exhaust pipe main pipeline 100 and exhaust pipe secondary duct 200；The front end of the exhaust pipe main pipeline 100 is connected to exhaust manifold, tail End connection exhaust outlet spray head 2；

The front end of the exhaust pipe secondary duct 200 is connected to 100 front of exhaust pipe main pipeline, forms exhaust pipe first Threeway fork 101；The rear end of the exhaust pipe secondary duct 200 is connected to 100 tail portion of exhaust pipe main pipeline, forms exhaust pipe Second threeway fork 102, the muffler 1 are set in the exhaust pipe secondary duct 200；First threeway fork 101 And second the bending radius of curvature of exhaust pipe main pipeline 100 described between threeway fork 102 be greater than the muffier-in pipe Bending radius of curvature；

It goes here and there and is equipped between first threeway fork 101 and the second threeway fork 102 on the exhaust pipe main pipeline 100 Electronic valve 3 controls opening or closing for this section of exhaust pipe main pipeline 100.

The angle of the exhaust pipe secondary duct 200 and 100 air inlet section of exhaust pipe main pipeline at first threeway fork 101 It is 90 degree, naturally it is also possible to slightly less than 90 degree, electronic valve 3 is opened as long as can guarantee, through 100 row of exhaust pipe main pipeline When gas, air-flow will not partially flow to exhaust pipe secondary duct naturally.

The caliber of the exhaust pipe secondary duct 200 is less than the caliber of the exhaust pipe main pipeline 100.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model is answered described with power Subject to the protection scope that benefit requires.
