EGR reduces the amount of Nox
Reduces the specific heat ratio of the combustion gases and hence the power
5. Increase in particulate emissions 6. HC DeNOx as a non-selective NOx reduction method using HC components in suitable catalytic converters. 7. HC DeNOx processes have only a very narrow NOx reduction temperature window and are therefore mainly effective in urban cycles.
