Understanding the Exhaust and Emission System

In order to register and legally and safely drive an automobile, it must be able to pass an annual state-mandated emissions test. This helps ensure your vehicle's exhaust system doesn't release fumes into the atmosphere with a higher concentration of waste chemicals than is considered safe. Plus, if your vehicle's emission system isn't functioning properly, its performance will suffer. It may have problems starting, idling or running properly, gas mileage will decrease, you may hear unusual noises, or your tailpipe will emit clouds of white or black foul-smelling smoke. Plus, dangerous, deadly, carbon monoxide may even seep into your vehicle's cabin.

Understanding the Exhaust and Emission System

Your vehicle's exhaust system consists of several important interconnected parts. All of them most work properly for the automobile to deliver optimal performance and reduce air pollution. Some key components of the emissions and exhaust systems of an automobile are:

  •        Exhaust Manifold
  •         Catalytic Converter
  •         Oxygen Sensor
  •         EGR Valve
  •         Muffler
  •         Flanges
  •         Gaskets

Interconnected pipes filter and route emissions away from the engine compartment, through the muffler and out the tailpipe. The catalytic converter filters out around 90% of the unburned fuel, acidic contaminant particles and dangerous gasses from the engine exhaust. The manifold and muffler cool the exhaust, muffle the loud expulsion noises and usher it out the rear of the vehicle. The flanges and gaskets join the exhaust system components together and minimize the leakage of the dangerous gasses released as the internal combustion engine works to power the automobile.

Service the Components Regularly

Don't wait for your check engine light to go on or you are about to do your annual emissions test before having your vehicle's exhaust system serviced. For your automobile to deliver peak performance, it's important to have the exhaust system serviced regularly by properly trained auto repair technicians using the right equipment, tools and methods. They will identify and address minor problems before they become major, complex, expensive, ones. Having your exhaust and emissions system periodically serviced and repaired can help your vehicle be safer, perform better and last longer.
