Evolution of Auto Exhaust Catalysts: Dr. Haren Gandhi invents three-way catalysts for cleaner exhaust

Improvements in fuel economy and reduced emissions are largely the result of fuel additives and exhaust catalyst equipment working to clean up the chemicals emitted when fuel is burned. This Friday, April 7th, marks the 25th anniversary of the issue of a seminal patent in the field of automotive exhaust catalyst. The inventor, Indian-born American inventor Haren S. Gandhi, is an inductee this year into the National Inventors Hall of Fame. Today, we’ll take the opportunity to revisit our Evolution of Technology series to look back at the development of technologies which have left us with cleaner breathing air than we would have had thanks to Americans’ heavy reliance on automobiles.
