Numerical modelling and analysis of influence of engine operating variable on engine emission using MATLAB

Abstract

The numerical modelling of influence of engine design and operating variables such as types of fuels, calorific value, piston bowl diameter and emission variables on engine emission have been developed through empirical equation, the equation have been constituted with variables and were obtained from the engine test results. The MATLAB coding has been developed with respect to available testing data. The developed model have shown the results agreed with closest to the real time values. Therefore the influence of piston bowl diameter, calorific value and various types fuels such as isobutanol, methanol, ethanol and gasoline on NOx emission have been simulated with the help of developed model. The results were seen closest to the real time value.
