Basics Explanation of Exhaust System and Muffler!
So that vehicle owners understand the importance of an exhaust system and the connected muffler here is some information to explain the purpose of these two components, the Emissions Control System and the Catalytic Converter!
Emissions Control System:
The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons, carbon monoxide, and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere through the muffler and tailpipe. Hydrocarbons are also emitted as a result of the vaporization of gasoline and from the crankcase of the automobile. Government regulations have set specific limits as to the amount of each of these pollutants that can be emitted into the atmosphere. The manufacturers’ solution was the addition of certain pollution control devices and the creation of a self-adjusting engine. As the computer systems in automobiles progressed, they were able to adjust ignition spark timing as well as operate the other emission controls that were installed on the vehicle. The computer is capable of monitoring and diagnosing itself, which assists mechanics in determining the proper repair when it fails.
Catalytic Converter:
Automotive emissions are controlled for 3 Reasons:
- To promote complete combustion so that there are fewer by-products
- To reintroduce excessive hydrocarbons back into the engine for combustion
- To provide an additional area for oxidation or combustion to occur (the catalytic converter).
The catalytic converter looks like a muffler and is located in the exhaust system in front of the muffler. Simply stated, as hydrocarbons or carbon monoxide in the exhaust are passed over the catalyst, it is converted to carbon dioxide and water. As the converter works to clean the exhaust, it generates heat. The dirtier the exhaust, the harder the converter works and the more heat that is generated. That is why our fuels for automobile engines are now unleaded; and cleaner to burn thereby reducing the heat buildup in the catalytic converter.
Although an exhaust system is complex and generally causes vehicles to be less fuel efficient, they have been made proficient in controlling poisonous pollutants and are vital to the quality and protection of our atmosphere.
If you need a new muffler or an inspection of your exhaust system, the mechanics at Gary’s Quality Automotive are happy to help you. Contact our ASE-Certified Technicians by calling (308) 381-2295 for more information. Our auto shop proudly serves vehicle owners in Grand Island, NE, Wood River, NE, and Doniphan, NE.
Gary's Community Event for March
On St. Patrick's Day, Saturday, March 17, 2012, from 11:00 a.m. to 3:00 p.m., Gary's Quality Automotive is/ was proud to be the host site providing the WARMTH for the CHILD SAFETY SEAT INSPECTION provided by the Child Safety Department at St. Francis Medical Center. This event is/was by Appointment only, by calling 308.398.6584. Don't leave your child's transportation safety to luck!
