What Comes In Must Come Out

The car has diverse systems that work in harmony to make it run. This makes the car highly comparable to the human body. In order for a person to live well, all of the systems must be running smoothly. Just the same, the car needs to have all of its systems operating in good condition. So if a person has the circulatory system, the car has the engine and the ignition system. Since people eat, they need to digest what they consumed so that waste could be eliminated. Hence, the human body has the digestive system and the excretory system. Likewise, the car has its own emissions control system, and then the exhaust system. Both systems help the car filter out combusted fuels as well as noxious waste or emissions. Noticeably, both the human body and the car follow the same principle---“what comes in, must come out.”

There are important car parts in this process. They are the exhaust pipes, the catalytic converter, the exhaust manifold, and the tail pipe. The car needs to be fed with fuel for its combustion process. But, during the engine’s operation, not all of the fuel will be utilized. Some unburned fuel particles will be left. While the catalytic converter may try its best to clean the car, it may be not enough. Hence, the only solution is to throw out what is harmful to the car.

From the engine, the fuel will travel to the catalytic converter through the exhaust pipes. The catalytic converter will then begin to regulate emissions of the car by oxidizing both carbon monoxide and the unburned hydrocarbons. After which, the exhaust manifold will collect the emissions before it leaves the tail pipe. It must be noted though that the exhaust manifold can restrict the performance of the car. Hence, headers are used as substitutes. Headers will allow “low restriction,” but this is not always recommended as they are not as effective when it comes to emissions. They are only advised for race cars.

What comes out of the tail pipe is ideally something that has already been filtered. This will help cars reduce the pollution they inevitably generate. One must remember that the engine needs clean fuel too, hence the installation of assemblies such as the emissions and exhaust system. After all, what comes in to the car is what comes out of it. So if one will only feed the car clean oil, then the emissions will be cleaner too.
