The ratio between NO2 and NO determines which reactions take place and how fast. The highest conversion rates are achieved if equal amounts of NO2 and NO are present, especially at temperatures between 200°C and 350°C. If there is more NO than NO2, fast SCR and standard SCR take place sequentially.
