An emissions test is a test conducted on vehicles to check for pollutant emissions formed by the engine of a car. There are usually specific standards a vehicle must pass to be cleared from the emissions test. Given that motor vehicles are among the top sources of air pollution, keeping tailpipe emissions at bay is crucial for improving air quality and reducing negative environmental impact. That’s exactly why the Pollution Control Board (PCB) prescribes strict emissions standards and why every Indian state conducts emissions tests to make sure vehicles meet those standards.
Emissions tests are designed at ensuring that the levels of toxic gases produced by vehicles on the road do not exceed the defined limits. These tests measure the volume of tailpipe emissions produced by car engines, in order to check whether a vehicle meets the regulations that restrict emissions of specific pollutants. They take in account the levels of nitrogen oxide (NOx), carbon monoxide (CO), particulate matter (PM), non-methane organic gases (NMOG), and formaldehyde (HCHO). Nevertheless, there are times when an engine fails this test. Further down are some of the common reasons for failing an emissions test.
If you are not sure where your vehicle stands? We’re taking a look at how these tests that are conducted and what the most common causes for failure are, so that you can have those issues fixed before your test. In many cases, car possessors or a mechanic can easily resolve the issues leading to a failed emissions test.
