How does the exhaust systems of my car work?
We don’t want to bore you with every detail, but we do want you to have an idea of the complexity of today’s car exhaust systems. At Discount Car Care we can handle all aspects of your car’s Muffler and Exhaust System requirements The purpose of the exhaust/emission system is to lessen the sound made by the engine, reduce the temperature and control the emissions the of your vehicle. Vehicles create gases while the engine is running. The catalytic converter is the component in the exhaust system turns these gases into mostly harmless ones that do far less damage to the environment. Some of the harmful gases that the exhaust system controls are Carbon Monoxide, Nitrogen Oxides, Phosphorus, Lead and Other Metals The exhaust manifold moves gases from the combustion chambers of the engine to the exhaust pipe. It is usually cast iron and its smooth curves improve the flow of exhaust.
As stated above, the catalytic converter helps reduce harmful emissions from engine exhaust. It uses a combination of heat and metals that act as catalysts. A catalyst is a metal (or chemical) that causes other chemicals to go through a reaction without being affected itself. The inside of the catalytic converter consists of metals such as aluminum oxide, platinum palladium. These metals cause the carbon monoxide and hydrocarbons to react and produce water vapor and carbon dioxide which are much less harmful to the atmosphere. The muffler alone cannot totally quiet engine noise. Many exhaust systems also include a resonator which acts as a mini muffler. They are usually straight pipes filled with sound muffling materials. The resonator can be either before or after the muffler in the exhaust system. Exhaust pipe connects all the other parts of the exhaust system.
The muffler quiets the noise of the engine. There are two sorts of mufflers. Those with baffled chambers to reduce noise; as sound waves move through this type of muffler, they bounce off the baffles and expend their energy inside the muffler, losing force and volume. The other type the exhaust is forced straight through a perforated pipe that contains metal, fiberglass, or other sorts of sound-absorbing material. This muffler is designed to reduce back pressure (exhaust going back up the pipes) and consequently makes a little more noise.
The tail pipe comes out of the muffler, past the rear bumper of the vehicle, directing exhaust gases away from the vehicle. On many newer cars it will also serve as a decorative function and is tipped in chrome.
