A modeling and simulation study on Pt-catalyzed conversion of automotive exhaust gases is presented. The model is based on a newly developed surface reaction mechanism consisting of 73 elementary-step like reactions among 22 surface and 11 gas-phase species. Reactions for the conversion of the major pollutants CO, CH4, C3H6, and NOx are included. The mechanism is implemented in a two-dimensiona...

Selective catalytic reduction (SCR) technique has been widely used for the abatement of the nitrogen oxides (NOX) emissions from diesel engines for decades. The urea-water solution (UWS) spray over the exhaust gases of diesel engines is one of the important methods used for exhaust after-treatment systems. The urea water solution is extensively injected in the upstream of the catalyst to genera...

Abstract: As day by day there is technological development seen all around world, the research work is progressing but the resources involved in them are depleting rapidly .The demand of resources and fuels for the technological development is increasing day by day. In order to keep the pace of development high there is a need to think about some alternate fuel with better efficiency which woul...

Improvements in the efficiency of combustion within a vehicle can lead to reductions in the emission of harmful pollutants and increased fuel efficiency. Gas sensors have a role to play in this process, since they can provide real time feedback to vehicular fuel and emissions management systems as well as reducing the discrepancy between emissions observed in factory tests and 'real world' scen...
