Abstract

The utility model discloses a novel exhaust system which comprises an exhaust pipe and an exhaust silencer. The rear end of the exhaust pipe is connected with the exhaust silencer and communicated with the external air. The exhaust pipe is connected with an exhaust manifold through an exhaust manifold interface in the front end of the exhaust pipe, and therefore a tail gas channel is formed. The exhaust manifold interface forms a horn-shaped connection front end, and the center of the exhaust pipe is coaxially provided with an air channel pipe. The air channel pipe is used for dividing the exhaust pipe into an annular pipeline, the front end of the annular pipeline and the horn-shaped connection front end, namely the exhaust manifold interface are communicated to form the tail gas channel. An air channel opening in the front end of the air channel pipe is connected to the center of the horn-shaped connection front end and communicated with the external air, and the rear end of the air channel pipe is connected with the exhaust silencer and communicated with the external air. The novel exhaust system is simple in structure, good in cooling, low in noise, long in service life, high in adaptability, capable of easily improving the comfort of a finished vehicle, economical and practical; the size of the exhaust silencer can be reduced in the front stage of design, space can be reserved for general arrangement, and the arrangement design of the finished vehicle can be facilitated.

Description

A kind of new-type vent systems

Technical field

The utility model relates to a kind of automobile-used parts, relates in particular to a kind of new-type vent systems.

Background technique

Vent systems is a pith of Motor Vehicle, comprise outlet pipe and silencing apparatus, the tail gas that a large amount of bands of Motor Vehicle have surplus heat will be discharged from outlet pipe, the outlet pipe using is at present due to not cooling effectively, along with the rising of air temperature, noise wavelength is elongated, causes the most at last silencing apparatus to lose efficacy, can not effectively eliminate the noise to exhaust sound, exhaust sound in car is continued to increase.

Summary of the invention

The technical problems to be solved in the utility model is, provides a kind of simple in structure, reasonable in design, new-type vent systems that temperature lowering effect is good, to overcome the existing above-mentioned deficiency of prior art.

The technological scheme that the utility model is taked is: a kind of new-type vent systems, comprise outlet pipe and exhaust silencer, described outlet pipe rear end connects exhaust silencer and is communicated with outside atmosphere, outlet pipe is connected with gas exhaust manifold by the gas exhaust manifold interface of its front end, thereby formation exhaust gas channel, described gas exhaust manifold interface forms a horn-like connection front end, the center of described outlet pipe is coaxially installed with an air duct, outlet pipe is separated into a looped pipeline by described air duct, described looped pipeline front end is communicated with and forms exhaust gas channel with the horn-like gas exhaust manifold interface that is connected front end, the air passage port of described air duct front end is connected in horn-like connection front end central authorities and is communicated with outside atmosphere, air duct rear end connects exhaust silencer and is communicated with outside atmosphere.

Its further technological scheme is: described gas exhaust manifold number of ports is corresponding with the cylinder number of motor, is 4,6,8,12 or 16.

Owing to adopting technique scheme, a kind of new-type vent systems of the utility model has following beneficial effect:

1. a kind of new-type vent systems of the utility model, at outlet pipe center, air duct is installed, be equivalent to offer ventilation flue in the middle of exhaust duct, vehicle is at running process, moving air can be taken away the heat in exhaust duct through passage, vent systems can better be lowered the temperature, guarantee that noise wavelength can not occur because of the rising of temperature sharply elongated, cause silencing apparatus to lose efficacy, not only control the low-frequency noise that vent systems is brought, improve car load NVH performance (improving car load travelling comfort), and be conducive to extend the life-span of vent systems;

2. because a kind of new-type vent systems of the utility model is low compared with other exhaust system temperatures, noise wavelength is shorter, can suitably reduce exhaust silencer volume early stage in vent systems design, wins space for general arrangement, is conducive to arrangement design;

3. a kind of new-type exhaust system structure of the utility model is simple, economical and practical, adaptability is good, goes for 4,6,8,12,16 Cylinder engines.

The technical characteristics of a kind of new-type vent systems below in conjunction with drawings and Examples to the utility model is further described.
