Author(s): Anuj Agrwal, Subhash Sharma
Abstract: Automotive three-way catalysts (TWCs) have represented over the last 25 years one of the most successful stories in the development of catalysts. The aim of this paper is to know about the technology for abatement of exhaust emissions. In the current understanding of TWCs, the specific role of the various components, new automotive catalysts-ceramic material, which can meet future highly demanding pollution abatement at low cost, has to be considered. In this paper, exhaust and environment, legislation and some controlling techniques for gasoline engine are discussed. Attention is focused on three-way type of catalysts; the paper is focused essentially on the catalytic aspects of pollution abatement, catalysts, etc.
