The majority of catalytic practitioners have been able to watch the growth of this technology from its inception to its current state of sophistication. Automotive catalytic converter technology is now in a mature state, and

The Chemical Reactions, point where conversions are high is commonly referred to as the operating “window”. A wide A/F range or window of high simultaneous NO., CO, and HC conversions is a desirable catalyst characteristic because it lessens the need for tight A/F control.

Here, the concentrations of oxidizing gases and reducing gases are matched, and equilibration of the exhaust mixture would yield only CO., H.O, and N.. The application of three-way catalytic converters has this objective. Three-way catalysts operate in a narrow A/F band between 14 and 15.

Emission Regulations in the United States,where waivers have been granted by the Environmental Protection Agency for specific vehicles. The law is currently under review (1982) so these requirements may be changed for future years. The 1981 exhaust standards represent a reduction from uncontrolled 1960 levels of 96% for HC, 96% for CO, and 76% for NO..
