Abstract

The selective catalytic reaction with ammonia has become established to reduce NO_x emissions during combustion in gas engines. Catalyst application and the introduction of the reducing agent represent a major challenge, especially for small engines. In this work, the aging phenomena of a commercial VWT catalyst after 17 months of operation of a 70-kW_el biogas gasoline engine are quantitatively determined. Using spatially resolved CFD it can be shown that these have no influence on the activity properties of the compact application.
