Abstract :
The purpose of this paper is to present the results of an experimental study of the performance and conversion efficiencies of ceramic monolith three-way catalytic converters (TWCC) employed in automotive exhaust lines for the reduction of gasoline emissions. Two ceramic converters of different cell density, substrate length, hydraulic channel diameter and wall thickness were studied to investigate the effect of varying key parameters on conversion efficiencies and pressure drop. Based on the emission test results, the conversion efficiencies from both converters were calculated and evaluated. After completing the test, the converters were cut to extract the substrate or ‘honeycomb’ inside the housingand being analyzed for microstructure and materialscomposition using Scanning Electron Microscopy (SEM) and Energy Dispersive Analysis (EDX). Simulation program using Commercial computational fluid dynamics (CFD) software packages, GAMBIT and FLUENT were used to verify experimental results
