What is an Emission Test? Why is it important?
If a car has been bought by an individual, and is of 3 years old, a road worthy test is a must. At the time of the test, the car has to undergo a few tests to prove that the car still in condition to be used by an individual. Of those tests, an important test is the emission test. In this test, the vehicle has to comply with the EPA (Environmental Protect Agency) standards to prove that it is limiting its negative impact on the environment. What happens during this test? This test is primarily done to identify and assess where the emission is from. It is assessed in two stages. The first is checking the emission at fast-idle speed, where the engine is made to run at 2500-3000 rpm. The emission of CO and HC will be checked in this stage of the check. The second is checking the emission at normal-idle speed, where the engine would be idle at 450-1500 rpm. The emission of CO alone is checked in the second stage. If the required standards are not met in the basic emission test, the
