This research paper investigates the implications of Hydrogen Internal Combustion Engine (H2 ICE) technology in the field of automotive thermal management, with a particular emphasis on truck radiator and charged air cooler systems. As the automobile industry works to shift to more sustainable and environmentally friendly solutions, hydrogen-powered vehicles provide a viable alternative to their conventional fossil fuel-powered counterparts. The study investigates the unique thermal characteristics of H2 ICE technology, the modifications required in H2 ICE technology due to specific requirements of air in the combustion, and changes in auxiliary components of the engine, where heating or cooling is required. Based on these changes, assess their impact on radiator and charged air cooler systems, which are critical components in maintaining the thermal equilibrium of internal combustion engines. Few inferences related to the impact on the Radiator and Charge Air Cooler are made after assessing different research materials. Later those inferences were compared with actual test results of 6.7L Hydrogen and Diesel engines at maximum power and maximum torque conditions. The study intends to understand the thermal dynamics, efficiency gains, and design issues involved with incorporating H2 ICE technology into automotive platforms using analysis of experimental data, and real-world performance assessments. Furthermore, the article investigates the problems and opportunities presented by using hydrogen internal combustion engine, including the consequences for radiator and charged air cooler design, and material compatibility. The findings of this study not only add to the emerging subject of hydrogen-powered transportation, but also provide vital insights for engineers and manufacturers working to improve the sustainability and thermal efficiency of future automotive systems.
