The exhaust system of a car is an important and necessary element of a vehicle’s overall structure. Providing a safe, efficient and quiet outlet for hot exhaust gasses is the primary function of the exhaust system in any automobile.
In addition to being very hot, these gasses are also under considerable pressure requiring an exhaust system to be strong, sturdy and free of leaks. Other considerations with regard to an automobile’s exhaust system include the scrubbing of dirty exhaust gasses before they enter the environment.
A long list of hydrocarbons, carbon monoxide, and other dangerous gasses are routinely produced by a combustion engine. The exhaust system must work flawlessly in a vehicle to ensure the safety of anyone traveling in a vehicle and to protect the environment.
Highly Efficient Exhaust Systems
The first section of the exhaust system that gasses travel through as they leave the combustion chamber is the exhaust manifold. The exhaust manifold is a gathering point for gasses from all combustion chambers. It is a place where these gasses converge as they prepare to travel through the exhaust system.
Car manufacturers and designers invest considerable time and money into developing highly efficient exhaust systems that help to increase horsepower and reduce emissions. The manifold is where it all begins.
As exhaust gasses travel from the exhaust manifold into exhaust pipes they move further along to the catalytic converter. This unique and very important component of the exhaust system converts dangerous gasses into inert gasses such as carbon dioxide, nitrogen, and even water.
Carbon Dioxide And Nitrogen Are Safe And Better For The Environment
The catalytic converter is tasked with the job of removing dangerous and harmful chemicals and gasses from the emissions that are produced by combustion. The catalytic converter processes a series of complex chemical reactions that safely converts gasses into more acceptable forms.
The highly efficient catalytic converter uses a ceramic type catalyst that in effect oxidizes gasses and changes them into more desirable inert gasses. Carbon dioxide and nitrogen are safe and better for the environment. As exhaust gasses continue on past the catalytic converter they pass by a variety of sensors that measure oxygen levels and other parameters.
In addition, gasses go through an exhaust gas recirculation valve that directs exhaust gasses back to the engine intake. These gasses are typically used in various concentrations to improve overall combustion.
The Resonator And The Muffler
As exhaust gasses complete their journey through the exhaust system they arrive at the resonator and the muffler. The primary responsibility of these two components of the system is to dampen and muffle noise.
This is accomplished by incorporating several adjacent plates within the muffler that cause combustion sound waves to in effect cancel each other out using a process known as resonance. Most mufflers contain several resonating type chambers arranged in series that are designed to strategically interfere with sound waves produced by combustion.
A canceling effect is created thereby greatly reducing the noise levels produced by a vehicle’s engine. Finally, the exhaust gasses exit the tailpipe and travel into the surrounding atmosphere. Trust your automobile’s exhaust system to reduce noise, improve efficiency and provide cleaner emissions.
