“…A subsequent reaction NNH + O = NH + NO then offers a high temperature pathway for NO formation, the so-called NNH mechanism. A number of experimental and modeling studies [27][28][29][30][31][32] support the existence of the NNH mechanism, and kinetic modeling indicates that it is of importance in premixed and non-premixed flames of both hydrogen [33][34][35][36] and hydrocarbons [37][38][39][40][41][42].…”

One of the remaining issues in our understanding of nitrogen chemistry in combustion is the chemistry of NNH. This species is known as a key intermediate in Thermal DeNO x , where NH 3 is used as a reducing agent for selective non-catalytic reduction of NO. In addition, NNH has been proposed to facilitate formation of NO from thermal fixation of molecular nitrogen through the socalled NNH mechanism. The importance of NNH for formation and reduction of NO depends on its thermal stability and its major consumption channels. In the present work, we study reactions on the NNH + O, NNH + O 2 , and NH 2 + O 2 potential energy surfaces using methods previously developed by Miller, Klippenstein, Harding, and their co-workers. Their impact on Thermal DeNO x and the NNH mechanism for NO formation is investigated in detail.

In the present study, a single cylinder four stroke dual fuel diesel engine was tested to investigate the performance and emission characteristics of various test fuels. The engine was tested in dual fuel mode using diesel and Karanja biodiesel blends as pilot fuel along with Natural gas as primary fuel with a constant gas flow rate under different loading conditions. From the experimentation it was found that smoke opacity and oxides of nitrogen (NOx)
