Abstract

integration of hydrogen as an alternative fuel in diesel engines has gained significant attention as means as an effective emission reduction while still keeps higher energy efficiency. Diesel engines can be modified to incorporate hydrogen injection alongside conventional diesel combustion. The integration of 3D modelling techniques with experimental data and validation further enhances the accuracy and reliability of the components results. The modelling process encompasses several stages, including measurement, geometry creation, and assembly process in order to produce adequate components which later on will be installed with the equipment on engine with or without modification. The simulation of simple diesel engine model with hydrogen injection has also been performed. MATLAB-Simulink simulation has emerged as a prominent tool to analyze and design dynamic systems across various domains and employ numerical solvers to solve ordinary differential equations, allowing for the time-domain analysis of dynamic systems. The simulation results obtained from MATLAB-Simulink provide valuable insights into the dynamic behavior of diesel engine systems. By analyzing hydrogen injections and diesel fuel controller over the time, the fuel consumption of both diesel fuel and hydrogen through their injections can be examined by the simulation. The result of simulation during 15 seconds shows the hydrogen can reduce significantly the diesel fuel consumption but the impact to rotation speed should be concerned since it goes higher which can created a mechanical failure. Comparing to simulation during 20 seconds, the optimal hydrogen injection in this simulation is 60 bars while it keeps the rotation speed oscillating around its reference.
