Objective: Reducing emissions and better quality of combustion are keen research areas in automobile. For better quality of combustion, modifications of engine features and utilizing novel fuels investigated in many researches. Methods: Hydrogen has very low ignition energy, high flame speed and helps to obtain ultra-lean-burn mixture. In this research work, the hydrogen mole fractions were added in the primary diesel fuel in the ranging from 10% to 90% with each interval of 10 % and varied equivalence ratio from 0.6 to 1.4 to examine the effect on velocity magnitude contour of airfuel particles and swirl motion. Results: All the results were obtained through simulations by using ANSYS Fluent 17 for Internal Combustion (IC) Engines. The addition of hydrogen increases the turbulence intensity of the fuel and leads to better quality of combustion. In addition, the swirl motion decreased because of addition of hydrogen addition and increasing the equivalence ratio.
Keywords: Contour Velocity Magnitude, Diesel Fuel, Equivalence Ratio, Hydrogen, and Swirl Ratio.
