Abstract
本实用新型公开的是一种发动机消音催化器，发动机工作时会产生巨大的噪音。目前，解决噪音问题是依靠发动机上连接的消音管来进行消音，但是对于排量较大的发动机来说，现有的消音管的消音效果不是很理想，同时由于结构设计的原因，消音管对于不同型号、功率和不同燃料的发动机的消音效果存在较大差异。本实用新型在消音器主体内，分别设置了进气管和出气管，并且将传统单独的消音管改进成了多个消音管从大到小套装在一起的形式。当发动机排出的气体从进气管进入消音催化器时，通过多个消音管的综合作用，声音得以消去。
The utility model discloses an engine silencer catalytic converter, which can generate huge noise when the engine is in operation. At present, the solution to the noise problem is to rely on the silencer pipe connected to the engine to silence the noise, but for the engine with a large displacement, the sound silencer effect of the existing silencer pipe is not very ideal, and because of the structural design, the silencer pipe is very important for the engine. There are large differences in the noise reduction effect of engines of different models, powers and different fuels. In the utility model, an air inlet pipe and an air outlet pipe are respectively arranged in the main body of the muffler, and the traditional single muffler pipe is improved into a form in which a plurality of muffler pipes are set together from large to small. When the exhaust gas from the engine enters the muffler catalytic converter from the intake pipe, the sound is eliminated through the combined effect of multiple muffler pipes.
Description
Technical field
The utility model relates to a kind of motor noise reduction catalyst converter, belong to the automotive industry technical field.
Background technique
Automobile is popular gradually, becomes the commodity of family, no longer is luxury goods once.Whole automobile industry is just in develop rapidly, but this has also caused a lot of new problems, and the noise that produces during engine operation is exactly one of them.Noise pollution belongs to a kind of novel environmental pollution problem with respect to traditional environmental pollution, mainly is that people itself is impacted.At present, solving noise problem is to rely on the hush pipe that connects on the motor to carry out noise reduction, but for the bigger motor of discharge capacity, the erasure effect of existing hush pipe is not very desirable, while is owing to the reason of structural design, there is larger difference in hush pipe for the erasure effect of the motor of different model, power and different fuel, and namely the adaptability of hush pipe is not strong.It is not strong how to solve hush pipe adaptability, and the problem of erasure effect difference is a problem that is worth further investigation.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of motor noise reduction catalyst converter, it is undesirable to solve existing noise reduction catalyst converter erasure effect, especially for the erasure effect difference of big-block engine and for the problem of the bad adaptability of variety classes motor.
Above-mentioned technical problem solves by the following technical programs, and a kind of motor noise reduction catalyst converter comprises muffler body, catalyst chamber, suction port, air outlet, one end of muffler body is provided with suction tude, and the other end is provided with steam outlet pipe, and suction tude is identical with the steam outlet pipe structure; Suction tude is welded on the suction port, is formed by 2-100 hush pipe suit, is distributed with bloop on each hush pipe.
Take the utility model of above-mentioned measure, in muffler body, be provided with suction tude and steam outlet pipe respectively, and will be in the past independent hush pipe has been modified into a plurality of hush pipes and has been sleeved on together form from big to small.When the gas of motor discharge entered the noise reduction catalyst converter from suction tude, by the comprehensive function of a plurality of hush pipes, sound was able to cancellation.When 7.8L CNG motor passenger vehicle was tested, erasure effect reached more than 95%, started and when moving, almost can't hear noise.It is simple and clear that the present invention has structure, reduces engine power loss, and air inlet/outlet pressure reduction is little, and adaptability is strong, the elimination efficiency advantages of higher
For describing the present invention in detail, below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.

Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 are the utility model hush pipe suit schematic representation;
Figure 10 is the plane of structure schematic representation of Fig. 9.
Embodiment
Shown in above-mentioned accompanying drawing, the utility model mainly is made up of noise reduction catalyst converter main body 1, suction tude 2, steam outlet pipe 3, suction port 4, air outlet 5, hush pipe 6, catalyst chamber 7, supporting clapboard 8, bloop 9.As shown in Figure 1 and Figure 2, noise reduction catalyst converter main body 1 is cylindric, and an end of noise reduction catalyst converter main body 1 is provided with suction tude 2, and suction tude 2 is in the noise reduction catalyst converter main body 1, one end is weldingly connected with the suction port 4 that is arranged at noise reduction catalyst converter main body 1 outside, and the other end stretches to catalyst chamber 7; Be provided with supporting clapboard 8 between suction tude 2 and the noise reduction catalyst converter main body 1, be used for supporting suction tude 2, prevent the gas leakage of weld bond cracking.As shown in Figure 4, suction tude 2 is by 2-100 diameter 50-200mm, length is that the hush pipe 6 of 50-1000mm is formed, hush pipe 6 diameter from inside to outside strengthens gradually, during installation such as Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, the pipe by minor diameter shown in Figure 9 be inserted in the big pipe of diameter step by step, being inserted in order is A → B → C → D → E, is covered with difform bloop 9 on the hush pipe 6, the diameter of circular bloop 9 is 4-8mm, and bloop 9 areas of other shapes are 3-300mm
2, the distance between the bloop 9 is 1-10mm.As shown in Figure 1, adjacent with suction tude 2 is catalyst chamber 7, in the catalyst chamber 7 catalyst carrier is installed.Steam outlet pipe 3 is arranged on the other end of noise reduction catalyst converter main body 1 inside, and is adjacent with catalyst chamber 7, suction tude 2 can be set to vertical with noise reduction catalyst converter main body 1 as shown in Figure 1, also can be arranged on the axial plane of noise reduction catalyst converter main body 1 as shown in Figure 3.Steam outlet pipe 3 is identical with suction tude 2 structures, and an end is weldingly connected with the air outlet 5 that is arranged at noise reduction catalyst converter main body 1 outside, and the other end stretches to catalyst chamber 7; Be provided with supporting clapboard 8 in order to support fixation hush pipe 6 between steam outlet pipe 3 and the noise reduction catalyst converter main body 1.
The utility model is work like this, and suction port 4 links to each other with motor, and the waste gas that motor is discharged enters suction tude 2 by suction port 4, again by cancellation noises behind the hush pipes at different levels 6 of suit.Waste gas enters catalyst chamber 7, in catalyst chamber 7 by the catalytic body catalytic purification.Purified gas is discharged air outlet 5 after through steam outlet pipe 3 noise reductions.So far, after the classification noise reduction, the noise of motor is by cancellation, and decibels reduces, and reaches the purpose of noise reduction.
