Hydrogen-fueled internal combustion engines (H2-ICEs) present a promising alternative to conventional fossil-fueled engines due to their potential for zero carbon emissions and high efficiency. However, several challenges remain in optimizing their performance, including low volumetric efficiency, pre-ignition tendencies, and thermal losses. This study focuses on improving the efficiency and performance of H2-ICEs through advanced direct injection (DI) strategies and effective thermal management techniques. Direct injection of hydrogen allows for better control of the combustion process, reducing the risk of knock and backfire while enhancing power output by improving air-fuel mixing and volumetric efficiency. The timing and pressure of injection play a critical role in achieving optimal combustion. Additionally, managing heat within the engine through techniques such as exhaust gas recirculation (EGR), advanced cooling systems, and thermal barrier coatings helps maintain optimal operating temperatures, reduce heat losses, and improve overall efficiency. By integrating advanced DI systems with thermal management approaches, this research aims to develop a comprehensive strategy for maximizing the performance of hydrogen internal combustion engines, making them a more viable and sustainable solution for future transportation and energy applications.
