Kinetic analysis of the role of selective NOx recirculation in reducing NOx emissions from a hydrogen engine

The kinetics of NO formation is used to study the effect of NO injected into a hydrogen engine on its emission characteristics. Considering the engine to be a variable-volume reactor, it is shown that the injection of NO reduces its further formation. In contrast to the earlier studies, it is highlighted that a reduction in the amount of NO can be achieved even if the reactions between the fuel and NO do not take place. Additionally, the...
