Best Answer

One of the main causes of air pollution in cities is emissions from cars and trucks. An old or poorly tuned engine will produce more pollutants than a new or well tuned engine. Old catalytic converters will allow more pollutants to leave the car and enter the air.

Emission checks are meant to discover vehicles that exceed the allowable emission limits and make the owner fix the vehicle or take it off the road.
