Optimization of Internal Combustion Engine Design and Performance Using Eco-Friendly Fuels with CFD and Flow 3D Cast Simulation

Abstract

The development of Internal Combustion Engine (ICE) technology continues to undergo innovation to increase efficiency and reduce exhaust emissions. The use of environmentally friendly fuels such as biofuels, hydrogen, and synthetic fuels based on renewable energy is increasingly the focus of research, especially in an effort to reduce dependence on fossil fuels. In this study, an analysis was carried out on the optimization of ICE design and performance by applying Computational Fluid Dynamics (CFD) and Cast 3D Flow simulation. This study aims to evaluate the effect of combustion chamber design modifications on thermal efficiency and exhaust gas emissions. The method used in this study is a literature study with a qualitative approach, reviewing various scientific publications related to engine design, combustion technology, and the impact of alternative fuel use on engine performance. The results show that design optimization through CFD can improve combustion efficiency and reduce NOx and particulate emission levels. In addition, the use of environmentally friendly fuels has been proven to be able to produce more stable power with more perfect combustion. These results indicate that the integration of numerical simulations in machine design can provide an effective solution to develop more efficient and sustainable ICEs. The study is expected to serve as a basis for further development in the automotive and renewable energy industries.
