Exhaust is a vital part in many vehicles, which only one of its functions is to transfer combustion gases out of the car. The exhaust is made of several different parts, each of which has an important role. Since the exhaust is the exit of corrosive gases with high temperature, the materials used in exhausting must be resistant to corrosion and high temperature.
What is the task of exhaust?
In exhausting, a set of parts are assembled together. In the exhaust made for many factory vehicles, most of the parts used are the same and similar. Each exhaust, in general, is responsible for several important tasks:
- این سیستم گازهای آلاینده و محصولات احتراق را از موتور به خارج از خودرو منتقل میکند.
- استفاده از اگزوز سروصدای تولیدی وسیله نقلیه را کاهش میدهد.
- وظیفه دیگر اگزوز، کاهش دما است.
Exhaust interface pipes
Exhaust pipes (exhaust pipe, connecting pipe and middle pipe) are another important part in exhaust manufacturing that connect the manifold, stock and exhaust head. The exhaust pipe must be made with high rigor and in accordance with the standards. The type of pipe, nominal diameter, length, radius of arcs and other characteristics determine the efficiency of the pipe and the amount of negative pressure reduction.
Catalyst
Air pollution is a problem that has attracted the attention of many manufacturers and is one of the most important issues in the world today. To reduce the level of emission of pollutants by the car, the exhaust system is equipped with a catalyst. This ceramic filter helps to protect the environment by refining the exhaust fumes. This ceramic piece is able to remove 90% of toxic pollutants.
Some believe that the catalyst lowers the car's acceleration while reducing emissions such as carbon monoxide and nitrogen oxides. This issue has led to the lack of interest of car owners. Some drivers open the catalyst and disconnect it from the exhaust pipe for more acceleration. Of course, it is better to know that this is a misconception and the catalyst has no effect on reducing acceleration.
Single Single (Source)
If you have looked closely at old classic cars, you will notice their loud and annoying noise. In the exhaust of new cars, the muffler stock is very important. This section reduces the vibration of the exhaust pipe and lowers the sound of the car. In the muffler, the gases are slowly expanded and their speed and thermal energy are reduced. In cars with a powerful engine, two silencers are used.
Output pipe
Finally, the smoke leaves the last part of the exhaust, the exhaust pipe. The outlet pipe from the side of the warehouse directs the gases out. Steel is used to make the exhaust pipe. The design of this pipe is also very important because if it is non-standard, it will reduce acceleration and efficiency.
