There are many ways to arrange the exhaust manifold, one side, one side two, and the other two sides. Now the exhaust pipe exhaust should be responsible for the design in addition to the engine, but also beautiful enough personality, which is the most common single exhaust with double exhaust, that in the end with an exhaust pipe with two exhaust pipes and what is the difference? How much more is the exhaust pipe? Let's talk about this problem today.

There are many ways to arrange the exhaust manifold, one side, one side two, and the other two sides. Now the exhaust pipe exhaust should be responsible for the design in addition to the engine, but also beautiful enough personality, which is the most common single exhaust with double exhaust, that in the end with an exhaust pipe with two exhaust pipes and what is the difference? How much more is the exhaust pipe? Let's talk about this problem today.

The role of exhaust pipe

1, reduce noise

When the car is running, the main muffler function is the muffler installed inside the exhaust pipe of the car, which greatly reduces the noise of the car. The principle is to split the air flow through multiple channels, and the friction between them is reduced so that the velocity of the air flow decreases gradually, so the cycle is repeated so as to reduce the noise.

2, reduce environmental pollution

The exhaust pipe has a purification device, when the high temperature exhaust gas passing through its purification device, three of which catalyze the effective purification of harmful gases in the exhaust gas.

3. Ventilation and exhaust

The exhaust pipe of a car is equivalent to the human breathing system. It can be pumped, compressed, worked and discharged in a circular way. If there is no exhaust pipe, the car will not run.

What is the design of the exhaust pipe?

- and displacement

If some cars, a thick exhaust pipe can not meet the demand, there is only one more. Because the exhaust efficiency is so high, you can often see two side-by-side exhaust pipes in large displacement cars. In particular, some sports cars require greater intake volume to speed up, exhaust pipe is specially designed to meet the suction, but also meet the exhaust emissions.

The structure of the engine - and

In the early years, the vehicles with bilateral exhaust usually used V type engines with more than 6 cylinders, so the V cylinders on both sides could use a set of exhaust gases respectively, requiring two three element catalysts and two sets of exhaust pipes. This is the most original bilateral exhaust, which means luxury and luxury. Of course, there are a lot of bold and low-key cars, such as the TOYOTA land cruiser with 4.6L displacement, and only a very small exhaust pipe on the rear side.

- poor exhaust will happen?

The exhaust system caused by the pressure, more intuitive understanding is that excessive back pressure exhaust that can not be carried out smoothly, will be blocked in the channel, or inside the cylinder, the exhaust gas can not be discharged smoothly, in order to discharge the waste gas, the more energy is needed, which will be launched, which will increase the power consumption of the whole machine; because the exhaust the exhaust gas in the cylinder, the exhaust gas temperature increases, higher volume, will take air into the cylinder, combustion affected.

Why does my car exhaust and not exhaust?

- enhance the sense of luxury

In addition to the traditional performance car, now 4 cylinder 2 liter and below the engine exhaust using bilateral There are plenty of people who just to cater to people, with a sense of luxury early cognition to the bilateral multilateral exhaust, and most exhaust are not the most pure, constrained by the cost of it only has a set of exhaust pipe, a three element catalytic converter in the end, only the silencer into two exhaust pipe, in addition to enhance the performance of the force, the contribution is almost zero.
