title: Numerical investigation of exhaust gas emissions for a dual fuel engine configuration using diesel and pongamia oil.
abstract: The investigation presented in this paper focuses on determination of gaseous exhaust emissions by computational simulation during combustion in compression ignition engine with pongamia oil substitution. Combustion is modeled using Equilibrium Constants Method (ECM) with MATLAB program to calculate the mole fraction of 10 combustion products when pongamia oil is burnt along with diesel at variable equivalence ratio and blend ratio. It had been observed that pongamia oil substitution causes decrease in the CO emission and increase in the NOxemission as the blend ratio as well as equivalence ratio increases.
