Prediction of CO and NOx Abatement in Catalytic Converter of a Compressed Natural Gas Vehicle (CNGV) Cold-Start Engine

Simulation and modelling of cold-start engine exhaust behaviour at catalytic converter is a difficult task as it involves complicated heat transfer processes and chemical reactions. This work presents a Computational Fluid Dynamics (CFD) calculation to predict the transient thermal and conversion ch...
