The development and application of hydrogen combustion technology for the retrofit of current heavy-duty**vehicles will help to fill a gap in the transition to clean transportation not covered by electric vehicles. Hydra**Energy Corporation aims to demonstrate that any heavy-duty diesel truck could be retrofitted to operate as a**dual fuel, hydrogen/diesel vehicle without power/torque/range loss while reducing diesel consumption and**emissions by 40%. However, one primary engineering challenge in the application of hydrogen combustion**technology is the long-term ageing and reliability of the retrofitted engine due to the effects of the hydrogen**fuel. This project will evaluate the impact of the severe environments produced in hydrogen diesel combustion**engines on the corrosion susceptibility of compacted graphite iron (CGI, a primary engine block material). The**work will also assess the combined effect of hydrogen pre-charging and adsorption on the subsequent corrosion**resistance of the CGI in these environments. The primary goal of this work is to acquire a better understanding**of the corrosion risks involved in retrofitting diesel combustion engines to hydrogen internal combustion**engines, and to develop an informed maintenance and inspection program to mitigate corrosion.

氢燃烧技术的开发和应用将有助于填补电动汽车无法覆盖的向清洁交通过渡的空白。海得拉**能源公司的目标是证明，任何重型柴油卡车都可以改装成**双燃料氢气/柴油车辆，而不会造成功率/扭矩/里程损失，同时将柴油消耗和**排放减少40%。然而，氢燃烧技术应用中的一个主要工程挑战是，由于氢燃料的影响，改装后的发动机的长期老化和可靠性。该项目将评估氢柴油燃烧发动机产生的恶劣环境对蠕墨铸铁(CGI，发动机机体的主要材料)腐蚀敏感性的影响。这项**工作还将评估氢预充电和吸附对这些环境中CGI随后的耐腐蚀性的综合影响。这项工作的主要目标是更好地了解**柴油内燃机改装为氢气内燃机**所涉及的腐蚀风险，并制定一套知情的维护和检查计划，以减轻腐蚀。
