**课程名称：** 汽车工程：氢内燃机 **课程概述：** 本课程深入探讨了在当前气候变化和能源安全挑战下，汽车工程领域将氢作为未来能源载体的重要性。课程重点关注氢内燃机（H2ICEs）以及氢燃料电池汽车（FCVs）的应用，特别是H2ICEs在发展中国家降低本地污染和提高负担能力方面的潜力。 课程解释了氢内燃机车辆（HICEV）是一种采用内燃机驱动的氢能源汽车，它与氢燃料电池汽车不同。HICEV本质上是基于传统汽油内燃机的改装。 由于氢不含碳，其燃烧不会产生一氧化碳（CO）、二氧化碳（CO2）和碳氢化合物（HC）等基于碳的污染物。然而，氢与空气在高温下燃烧会产生氮氧化物（NOx），这仍然受到排放法规的限制，因此H2ICEs并非零排放。 课程也指出了氢的潜在缺点，即其极小的分子尺寸使其难以储存和处理，容易发生泄漏，并且泄漏的氢气与空气混合后具有潜在的爆炸风险。
In the field of Automotive Engineering , the threat posed by climate change and the striving for security of energy supply are issues high on the political agenda these days. Governments are putting strategic Automotive Engineering plans in motion to decrease primary fossil fuel energy use, take carbon out of fuels and facilitate modal shifts in the area of tail pipe emissions.Taking a prominent place in these strategic plans is hydrogen as a future energy carrier.A number of manufacturers are now leasing demonstration vehicles to consumers using hydrogen-fueled internal combustion engines (H2ICEs) as well as fuel cell vehicles. Developing countries, in particular, are pushing for H2ICEs (powering two- and three-wheelers as well as passenger cars and buses) to decrease local pollution at an affordable cost.A hydrogen internal combustion engine vehicle (HICEV) is a type of hydrogen vehicle using an internal combustion engine. Hydrogen internal combustion engine vehicles are different from hydrogen fuel cell vehicles (which use electrochemical use of hydrogen rather than combustion). Instead, the hydrogen internal combustion engine is simply a modified version of the traditional gasoline-powered internal combustion engine.Hydrogen does not contain carbon. That means, that there are no carbon based pollution in the exhaust like carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbons (HC). However, hydrogen combustion with air produces oxides of nitrogen, known as NOx, against emission regulations. In this way, the combustion process is much like other high temperature combustion fuels, such as kerosene, gasoline, diesel or natural gas. As such hydrogen combustion engines are not considered zero emission.The downside is that hydrogen is difficult to handle. Due to the very small molecular size of the hydrogen atom, hydrogen is able to leak through many apparently solid materials. Escaped hydrogen gas mixed with air is potentially explosive.
