Car Exhausts - A Vital System For Your Car

Car Exhausts - A Vital System For Your Car

Your car's exhaust system dissipates the gases released by the engine. They can be potentially harmful to drivers, bystanders, and the environment if they're not properly dealt with. Understanding how car exhausts work, one should know how each individual component contributes to the system as a whole.

The air pump pumps compressed air into the exhaust manifold. Driven by a belt that is connected to the engine, the air pump allows the oxygen pumped along with the compressed air to aid in burning unburned fuel left on other parts of the engine, which converts carbon monoxide to carbon dioxide.

The exhaust manifold, which was mentioned above, is attached to the cylinder head and leads the car exhausts gases created by the engine from combustion chamber to the exhaust pipe at the end of the car. The exhaust manifold can be found under the intake manifold. They're made of cast iron, stainless steel, or aluminum.

Catalytic converters are installed in the exhaust line between the mufflers and exhaust manifold. It converts the gas emissions like carbon monoxide into the less dangerous form carbon dioxide and water. It basically lessens the pollution caused by the car. The converter is lined with chemicals that change these harmful substances into harmless ones before they leave the car.

The muffler is made of metal and easily the most recognizable part of the car exhausts system. It is connected to the under body of the car, and its main function is to reduce the noise of the exhausts system.

The engine combustion process creates gas emissions. A lot of noise is generated when gases leave the engine. There's also a great deal of noise created by the opening and closing of the car exhausts valves. The muffler converts that sound energy and extreme pressure into heat, dissipating the sound waves' energy.

The first type of mufflers will bounce the gas around to lower its energy with baffles, while others have pipes wrapped in specific metals that absorb the noise.

The final component of the car exhausts system is the tail pipe. It's the part the sticks out of the back or your car, and is attached to the muffler. It releases the gases that have passed through the rest of the system and into the environment.

Modern cars often include oxygen sensors as part of their car exhausts because optimal performance depends on an exact proportion of fuel mixed with oxygen. Hopefully understanding the individual parts of the car exhausts system will help you in purchasing a car and also help you understand the steps taken by manufacturers to curb pollution and maximize performance.
