Although the exhaust pipe is a small pipe, it contains a lot of secrets. The main function of the exhaust pipe is to exhaust and silence. The composition of the entire exhaust system is: exhaust manifold, catalytic converter, mid-muffler(glasspack), muffler and the pipe connecting them. The exhaust manifold is installed on the cylinder head, the other end is connected to the front section exhaust pipe, and then the middle section and the rear section are connected in turn. Except for the two ends of the exhaust manifold fixed with bolts, the other entire pipelines are hoisted by rubber The ear suspension is hung under the car body, and it can swing up and down and left and right when the road is bumpy, so that the vibration generated by the exhaust will not be transmitted to the cabin.

I believe that many car lovers have experienced the same thing. A component of the car system was damaged. When I went to a repair point for repairs, I was told that the entire pipeline including Sanyuan was replaced. If you have the same experience, then you must know which product I am going to give you popular science today.

Automobile engines are always connected with a pile of twisted and bizarre metal pipes. These pipes are divided into multiple pipes, made of cast iron or welded with stainless steel. Their scientific name is exhaust manifold.

The 400 horsepower exploded by the 2.5T inline five-cylinder engine is seriously inconsistent with its compact body. Coupled with the easy handling characteristics brought by the short wheelbase, this kind of power is surging, and the feeling of where to hit is fascinating.

Ordinary car enthusiasts, put their name on the driving license. Veteran car enthusiasts, put their name on the car body. Great car enthusiast, put their name on the car logo.

Since 2021, there has been a surge in thefts of three-way catalytic converters around the world.

The three-way catalytic converter is a metal device installed in the exhaust system of a vehicle. Its purpose is to reduce the pollutants released into the atmosphere when the internal combustion engine is running. They are made of precious metals, including platinum, palladium and rhodium.Although it was first introduced to the U.S. market in the 1970s due to EPA requirements. However, other countries began to pass laws mandating installation. That's because three-way catalytic converters have done an excellent job of reducing pollution in cities like Los Angeles, which have a serious "smog" problem.

The muffler is an important structural element of the exhaust system, without which the operation of a modern car is simply impossible. A car muffler has the following main functions.
