Analysis of NO formation characteristics and its control concepts in diesel engines from NO reaction kinetics

Abstract This paper investigates NO formation characteristics in diesel engines with a variety of emission control concepts, and offers answers to basic question about NO reaction characteristics. The NO formation was calculated by Extended Zel'dovich Reaction Kinetics in a diffusion process. The results shows that the NO formation rate is independent of the mixing of combustion gas, and that internal EGR (combustion gas mixing in a cylinder) has no effect on NO reduction. It was found that NO is roughly proportional to the inverse of engine speeds. The paper also shows the potential of two stage combustion, and its effect strongly depends on the time-scale of mixing.
