In this paper, computational simulation on the effect of combustion temperature on emissions characteristics of hydrogen-fuelled compression ignition engine was performed. Combustion process was modeled based on Equilibrium Constant Method (ECM) and programmed using MATLAB program in order to calculate mole fractions of 18 combustion products when hydrogendiesel fuels blends is burnt at variable combustion temperatures. It is observed that throughout all equivalence ratios, higher temperature increases H2, CO, HCN, atoms C, O and H, NO, OH, NO2 and O3 emissions and decreases CO2, H2O, NH3 and CH4, N2, O2 and HNO3 emissions. The highest H 2O emission occurs during stoichiometric combustion and decrease in combustion temperature causes insignificant changes in atom N emission.
