Question:
everyone. I saw some big ass the size of the motorcycle exhaust after two barrels, I would like to ask this dual motorcycle exhaust internal barrel is a principle of how to work? You to tell us about this car now. I do not know. In addition, small high game and high-Cypriot faster I do not see where, why has such a big voice?

Answer:
you have two-bicycle discharge pipe of the motorcycle, in fact, there are different situations.
some two-cylinder motor, each cylinder leads to a bicycle discharge pipe, respectively. This vehicle engine power, and speed faster displacement generally above 150CC.
the other is the single-cylinder engine but the exhaust pipe is divided into two leads to the car. This multi-is to look good, there is no practical significance. However, due to an increase in the exhaust pipe, exhaust resistance is relatively small, there are certain to increase the role of power, a more balanced voice. Some car
In order to increase the power but without the installation of straight exhaust muffler, so the sound is particularly great.

Answer:
exhaust is the simple elimination of reduction of that issued by a motorcycle engine noise, or sound very harsh. Muffler is a
eliminate noise generated by the voice of the spread, so that gas and air flow through the prevention and control of environmental noise pollution arising from human, animal and plant equipment. It is different from many species, the spread of the principle of porous sound-absorbing material and metal composition of the exhaust short role. What advantages do not exist
or shortcomings, if you are willing to face even the exhaust pipe 4 can be, made it an exhaust pipe can also be, but can be larger in diameter the

Answer:
known as the exhaust pipe muffler, its main function is to reduce vehicle noise. Secondly, there are thermal effects. dual exhaust design can reduce the exhaust resistance. enable enhanced power.
small high game and high-side using a “line” ; so loud.

Answer:
I agree with the second answer is correct but there are two-cylinder 125cc is Wang Ying, 150cc-shaped 125cc. The so-called dual-exhaust engine is running relatively large displacement single-cylinder pressure caused by lack of will power down to reduce operations. Some also have single-cylinder dual exhaust there are two possibilities.2008-06-02
问题:
大家好。我看见一些大体积的摩托车屁股后有两个排气桶，请问这种双排气桶的摩托车内部是个怎么样的工作原理？大家给介绍一下这种车吧。我对这不懂。还有，小高赛和大高塞我见速度也快不到哪，为什么声音却那么大？

回答:
　　你说的有两个排气筒的摩托车，其实有不同的情况。
　　有的是双汽缸的摩托，每个汽缸分别引出一个排气筒。这种车发动机动力大，车速快，排气量一般在150CC以上。
　　另一种是单缸发动机却把排气管分成两支引出到车后。这种多是为了好看，没有什么实际意义。但是，因排气管增多，排气阻力相对较小，也有一定的增加动力的作用，声音也较平衡。
　　有的赛车为了增加动力性而不安装消声器而是直排气，所以声音特别大。

回答:
排气简单说就是xx减少摩托车发动机发出的的噪音，否则声音很刺耳。
消音器是一种能xx声音传播产生的噪音，使气体和气流通过的，防治环境噪音对人类和动植物产生污染的设备。它是由多段不同通体，多孔扩散原理及金属吸声材料组成的排气放空作用。
不存在什么优点或者缺点，如果你愿意甚至弄成4个排气管都可以，弄成一个排气管也可以，只是直径大一些就可以了

回答:
排气管又叫消声器,它的主要作用就是减小车辆噪音.其次还有散热作用.双排气的设计可以减小排气阻力.使动力增强.
小高赛和大高塞使用的是"直排"所以声音大.

回答:
我同意第二位的回答是对的不过双气缸125cc也有就是鹰王、150cc形的125cc。所谓的双排气就是发动机的运行比较大单排量不足会引起气缸压力减轻行动力减慢.有的单气缸也有双排气有两种可能.2008-06-02
