The Importance of Emission Testing for your Vehicle Understanding Environmental Impact


Emission tests are used to decrease the amount of pollutants that your vehicle releases because they evaluate the levels of hazardous materials that may be released by your vehicle. Pollutants released by your vehicle can be harmful to the environment and you. Having an emissions test performed is essential and beneficial because it can help improve air quality.


Understanding the Emissions from Your Vehicle

By bringing your vehicle to Speed Auto Repair or by having us come to you, we can help ensure that your vehicle runs efficiently and reduce the amount of pollutants released by your vehicle. Manufacturers have supported the decrease in pollutants released by your vehicle. For example, a catalytic converter changes harmful emissions into those less harmful before they are released from your vehicle. When exhaust recirculates, vales and positive crankcase ventilation systems will work from different areas of the vehicle to filter through vapors and cool them down in the combustion chamber, thus reducing fumes that are caused by too much heat. Excess pollutants can be caused by a variety of reasons, including problems with engine components, a deteriorating exhaust system, etc.


The Purpose of Emission Testing

Having an emissions test performed is performed to determine the amount of pollutants produced by your vehicle. For example, A tailpipe test is usually performed to determine the amount of specific gases vented in your car’s exhaust. An on-board diagnostics (OBD) test will be performed to determine the condition of emissions system components.

The test is based on repeatable and comparable measurements of exhaust emissions for different engines and vehicles. The tests performed are done so in cycles, that specify conditions that the engine is operating at. Specified parameters in a test cycle can include a range of conditions, such as operating temperature, load, and speed. The test performed is designed to simulate real-world conditions.


Why Emissions Testing is Important

Reducing the amount of harmful pollutants that can cause issues to people, animals, and the environment is a critical component of emissions testing. Pollutants can harm soil, lakes, and streams. Corrosion induced by pollutants can also impact structures such as buildings and monuments. Therefore, having your emission test performed can help you have a more positive impact on the environment.

Having your vehicle serviced regularly can also help to provide a safe and comfortable ride for you and your passengers.
