### Abstract

The investigation presented in this paper concerns on the computational simulation of emissions characteristics in compression ignition engine with hydrogen substitution. Combustion process has been modeled based on Equilibrium Constants Method (ECM) with MATLAB program to calculate the mole fractions of 18 combustion products when hydrogen is burnt along with diesel fuel at variable equivalence ratios. It can be observed that hydrogen substitution causes significant increase in NH_{3}, H_{2}, atom H emissions during rich combustion and OH, NO_{2}, HNO_{3} emissions during lean combustion. As the equivalence ratio increases during rich combustion, mole fractions of HCN, CH_{4}, CO and atom C decreases with increment of hydrogen substitution. N_{2}, atom N and CO_{2} emissions decrease whereas no significant changes in O_{2}, NO, O_{3} and atom O emissions throughout all equivalence ratios as hydrogen is added to the combustion.
