Although most automobiles now on the road are equipped with a three-way catalyst to minimize their emissions of NOx, CO, and unburned hydrocarbons, pollution from automobiles remains a major problem. The great bulk of these emissions is due to the cold start problem (i.e., the fact that a car engine produces pollutants from the instant it starts, but the catalyst is effective only after it is heated to operating temperature). To solve this problem, a minor change is proposed in the mode of operation of the three-way catalyst systems now in use. With this small change in the operating mode and no change in the catalyst itself, the catalyst becomes able to instantaneously heat itself to operating temperature, eliminating cold start emissions.

This technology has the potential to greatly reduce pollution from automobiles at a very modest cost.
