 Exhaust emission characteristics of stoichiometric combustion applying to diesel particulate filter(DPF) and three-way catalytic converter(TWC)Seongin Jo, Junepyo Cha and Suhan Park Energy, 2022, vol. 254, issue PB Abstract: Various researchers study after-treatment system (DPF, SCR, LNT, TWC) to meet the recent strengthening regulation. In this study, we consider the intake air applying to the simulated-EGR which is composed of synthetic constituents (e.g. air, N2, and CO2 gas). Intake air excessively used to simulated-EGR, proceeds with the stoichiometric air-fuel ratio combustion in the cylinder. This stoichiometric exhaust emission was passed through and converted in TWC as well as DPF after-treatment system. We discuss exhaust emission characteristics of stoichiometric combustion applying to DPF and TWC in compression ignition diesel engine. The maximum of the conversion efficiency of NOx is 85.7% at SOI of −18.2° CA. aTDC with simulated-EGR the smoke reduction efficiency of soot is high and is provided over 99% reduction under the stoichiometric condition with reduced O2 mole fraction by adding only N2 and with EGR.
