Indiana is making steady progress toward reducing emissions of pollutants from industry, motor vehicles and other activities that contribute to the formation of ground level ozone in Lake and Porter counties.
Cars and light-duty trucks contribute 30 - 50 percent of the pollutants that cause harmful ground-level ozone and also contribute significantly to the amount of air toxics and particulate matter in the environment. The Clean Air Car Check program identifies vehicles that emit harmful pollutants and once repaired, those vehicles' performance and fuel economy are improved, as is the air we breathe. Properly maintained vehicles also result in less contamination being released into the groundwater.
The purpose of the the vehicles emission system is to control the emissions and exhaust from your vehicle. This system substantially reduces harmful gases and helps maintain quiet operation. The exhaust system contains a series of integrated components including the catalytic converter, muffler and tailpipe. Today’s vehicles also incorporate various computer sensors, such as the oxygen sensor, to help clean the gases that an internal combustion engine produces. Vehicle manufacturers have made great strides in reducing the amount of harmful gases coming from the exhaust system. If your vehicle fails the indiana emission test you will have to make the nessary repairs to renew your plates. |
