摘要：In this paper, theoretical analysis has been done to minimise engine emissions and safe knock limit by changing some operational and design parameters such as equivalence ratio, spark plug location, compression ratio, and cylinder diameter by using computer simulation model. For this purpose a zero dimensional knock model, two zone combustion model(one in front and one behind the flame front), and gas dynamic model have been incorporated. Subsequently, the Nitric Oxide exhaust emission concentrations have been predicted by using the rate kinetic model in the power cycle and along the exhaust pipes. Furthermore, Carbon Monoxide is computed under chemical equilibrium condition and then empirical adjustment is made for kinetic behaviours based upon experimental results. It is inferred that the value of cylinder pressure data, BMEP, BSFC obtained by using computer simulation model based on theoretical analysis are in closer agreement with those which are obtained by previous studies.
