M.Tech ThesisIndian Institute Of Technology, Delhi Jun 2016 - Jul 2017New Delhi Area, IndiaPublished an highest impact factor research paper; selected for presentation in ISCRE25 held in Florence, ItalyArea of research: Kinetic analysis of role of selective NOx recirculation in reducing NOx emissions without fuel interaction from a hydrogen engine.Key Results: 1. Developed Hydrogen engine MATLAB simulation model; Highlighted that NO injection reduces its further formation at certain conditions. 2. Achieved more than 90% NO conversion at high equivalence ratios (0.65<ɸ<0.9) and various amounts of NO injection; very low conversion efficiency was observed for lower ɸ (0.4 - 0.5).3. Deduced that conditions such as high equivalence ratio, high load & high compression ratio will result in a high NOx reductionApplication: Model can be used to design selective recirculation systems for an enhanced removal of NOx; applicable to all other fuels as well -
