Emission tests are being required by many states for vehicles. There are three categories of emissions. The first one is the tailpipe emissions, which is what most people talk about when it comes to air pollution caused by vehicles. The primary pollutants include carbon dioxide, carbon monoxide, nitrogen oxides and hydrocarbons.

The second category is the evaporative emission that is produced from the fuel evaporation and is also a big contributor to smog formation in urban areas. These are the heavier molecules that stay much closer to the surface of the ground. The last type is the life cycle emissions that are being produced during the manufacturing and disposal of a vehicle.

If your vehicle failed the emissions test, there is no need to worry because a good auto repair shop will be able to perform complete diagnostic services for determining the exact problem to ensure that the root problem will be addressed to avoid any future issues. They will then perform the proper emission repair for you to pass the emission test without any additional problem.

After the identification of the problem using their diagnostic tools, the expert technicians can address the issue by:

  • Muffler inspection
  • Evaluation of exhaust system
  • Oxygen sensor checking
  • Catalytic converter inspection
  • Making all the needed repairs

There is no doubt that emissions are now an extremely serious concern as the society becomes more aware of the dangerous pollutants that can be found in a vehicle’s exhaust. The exhaust system of your car is engineered to offer emission control and safety. In order to avoid any emission problem, it is best that you get the most out of the regularly scheduled maintenance being requested for keeping your exhaust system functioning in its optimum operating condition. This way, the system can control the emissions to the needed levels as it is originally designed to do.
