PGM, among an enormous range of application, are used as major elements in a Catalytic Converter used in vehicles as emissions control device that converts toxic pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction Catalytic converters are used with internal combustion engines fueled by either petrol (gasoline) or diesel—including lean burn engines.

The first widespread introduction of catalytic converters was in the United States automobile market. Manufacturers of 1975 model year equipped gasoline-powered vehicles with catalytic converters to comply with the U.S. Environmental Protection Agency's stricter regulation of exhaust emissions.

 

Now-a-days, a modern car emits, approximately, 10 times less pollutants than the car produced in the 70’s. Thanks to the development of new technologies on catalytic converters.
