Exhaust is one of the most important parts of motor vehicles. Because it is not possible to talk about the principle of an internal combustion engine in a vehicle without exhaust. It is a system found in internal combustion engines and at the same time that allows the burning gas to be discharged. In short, it is an automobile part that expels the waste gas.
Exhaust is a system that provides both the discharge of the burning gas and absorbs the sound. In this way, sound pollution is prevented. This system regularly throws out the waste gases accumulated in the engine and at the same time filters it. In addition, the water level in the exhaust is removed by evaporation.
This system consists of various parts. The parts that make up the exhaust are as follows:
There are two types of silencer:
Straight-Through Silencers: It consists of several interlocking pipes. The smoke entering the muffler continues without changing direction.
Reverse Flow Silencers: There are non-consecutive pipes and compartments inside the muffler box. Smoke entering the muffler expands and cools with back and forth movements. It is then thrown out in a way that has lost its voice and speed.
The sound produced by the running engine firstly enters the exhaust from the inlet pipe. The higher the speed of the vehicle, the louder the sound from the engine. Loud noise / noise coming from the exhaust pipe is transmitted to the muffler. Sounds coming into the muffler overlap each other and therefore lower each other's decibels. Also, sound waves entering the pipe enter through hundreds of tiny holes and exit through hundreds of tiny holes. Noises cannot be completely eliminated, but are reduced as much as possible. In this way, the sound of the exhaust decreases to a level that does not disturb people.
Exhaust pipes are made of non-rusting steel. Because the gas and water vapors produced by the vehicle while operating cause the pipes to rust. For this reason, these pipes should be produced from non-rusting steel material.
Also, the design of the exhaust is also very important. Because the more the waste gas goes out, the better the vehicle's engines and parts are cleaned. In this way, they work with much better performance.
