In every mechanism, there is a necessity for a system that can eliminate the used up fuel. This system is called the exhaust system and even in a typical car mechanism, the exhaust system holds a lot of value. It makes sure that the burnt out air-fuel mixture is eliminated from the engine, however that is not the end of its functionality. By eliminating this burnt out air-fuel mixture, the system can be cleaned off the emission and the unnecessary noise created by the leftover elements is automatically reduced.The designing and the condition of your exhaust system can have a negative impact on your car's performance as well as overall efficiency. So, it is very important to get your exhaust system routinely checked by top rated car mechanic Adelaide. A normal person who does not have much idea about car mechanisms, may fail to understand the system in which an exhaust works inside any vehicle. So if you are willing to understand the mechanism behind the exhaust system, you will have to first get familiar with the parts of the exhaust system. Here are some of the parts: Oxygen sensors There are mainly two oxygen sensors that are used in a typical exhaust system. One of the oxygen sensors is used for the exhaust manifold and the other is used for the catalytic converter. These sensors sense the amount of oxygen that is present within the exhaust gas. Exhaust manifold This part of the exhaust system is connected with the engine directly. The functionality of the exhaust manifold is to get the exhaust gases together and force them down one pipe. Catalytic converter As mentioned above, one oxygen sensor is used in the catalytic converter part, so that the harmful gases that are emitted from the burnt out air-fuel mixture can be eliminated. The oxygen sensors help in detecting these harmful gases like carbon monoxide and nitrogen dioxide. You can get the help of car exhaust services to reduce this emission of harmful gases and contribute towards pollution. Other parts There are other smaller parts like the muffler/silencer that help in reducing noise pollution caused by the exhaust. It can work for a variety of sound ranges unlike the resonator which is able to reduce noise to only a certain extent. It does not have the capability to reduce frequencies that are higher or lower and can only target a particular range of frequency. The last part of the exhaust system is the tail pipe which directly emits the gases out of the car into the air. How does the mechanism of the exhaust work? Now that you have learnt all about the parts of the exhaust and familiarize with them, you can better understand exactly how the exhaust works: Functionality of the exhaust manifold When the combustion engine works for the fourth cycle, some amount of exhaust gases are produced from the air-fuel mixture. The first part of the exhaust; the exhaust manifold which is connected directly with the engine, collects the gases that are produced. It has one cylindrical pipe which acts as the output, so when all the gases are collected from a variety of chambers they are forced down that single cylindrical output. There is a control poppet valve situated in the ending of the exhaust manifold cylindrical pipe which effectively controls the opening and closing of the pipe. Functionality of the oxygen sensors As mentioned earlier, oxygen sensors are used for detecting the amount of oxygen that is left in the exhaust gases. This helps in understanding if the car is able to effectively use the fuel or not. So, if there is less percentage of oxygen in the exhaust gas, it would denote that the fuel is being used in excess. The ECU can effectively start working upon the fuel delivery when the oxygen sensors send the signal. Functionality of the catalytic converter When the exhaust gases are forced to go through the single pipe from the exhaust manifold, they enter the catalytic converter. Here, all the harmful gases are broken down using two methods; oxidation and reduction. Oxidation turns the carbon monoxide into carbon dioxide which is a far less harmful gas. Similarly, the nitrogen dioxide is used to nitrogen and oxygen which are completely harmless. This is how the emissions are controlled in cars. If your cars have some unnecessary tapers, it can negatively affect the exhaust gas because of the back pressure that is created. This may reduce the performance of the car as well as increase your cost cutting for maintenance. To tackle this problem, the stock-piping are lined in a particular manner to avoid the creation of this back pressure. However, if your car lacks this system you can get it repaired by a top rated car exhaust system repair expert in Adelaide.
