This short overview briefly summarizes the prominent evolutions and scientific breakthroughs in the development of end-of-pipe technologies with respect to the standard regulations of atmospheric pollutant emissions from automotive exhaust. Up to now, several strategies have been implemented to fulfill more and more stringent emission limits and to overcome the extensive use of critical materials. This led to the elaboration of cheaper and more compact systems with close-coupled technologies suitable for light duty vehicles and also to preserve the competitiveness of car manufacturers. But all these improvements could not be sufficient to face short-term, more severe limitations as well as more realistic test driving cycles since the actual ones usually underestimate the emissions of current atmospheric pollutants especially from diesel powered engines. Presently, several scenarios have been envisioned which account for the partial replacement of liquid fossil fuels by alternative fuels for urban travel and the emergence of hybrid engines powered by natural gas or bio-fuels accompanied by more simple and efficient end-of-pipe systems. In this short overview, particular attention was paid to the past and present academic contributions which led and/or inspired important technical and commercial applications.

燃烧后催化的挑战和突破：如何匹配未来的严格法规

这份简短的概述简要总结了管道末端技术在汽车尾气排放的大气污染物排放的标准规定方面的显着发展和科学突破。到目前为止，已经实施了几种策略来满足越来越严格的排放限制并克服关键材料的广泛使用。这导致采用适用于轻型车辆的紧密耦合技术来开发更便宜，更紧凑的系统，同时也保持了汽车制造商的竞争力。但是所有这些改进措施不足以短期解决，更严格的限制以及更切合实际的测试行驶周期，因为实际行驶周期通常会低估当前大气污染物的排放，尤其是柴油发动机。目前，已经设想了几种方案，这些方案说明了用于城市旅行的替代性燃料部分替代了液态化石燃料，以及出现了由天然气或生物燃料驱动的混合动力发动机以及更简单有效的管道末端系统。在此简短的概述中，特别关注了过去和现在的学术贡献，这些贡献引领和/或启发了重要的技术和商业应用。已经设想了几种方案，这些方案说明了用于城市旅行的替代燃料部分替代了液态化石燃料，以及出现了以天然气或生物燃料为动力的混合动力发动机以及更简单有效的管道末端系统。在此简短的概述中，特别关注了过去和现在的学术贡献，这些贡献引领和/或启发了重要的技术和商业应用。已经设想了几种方案，这些方案说明了用于城市旅行的替代燃料部分替代了液态化石燃料，以及出现了以天然气或生物燃料为动力的混合动力发动机以及更简单有效的管道末端系统。在此简短的概述中，特别关注了过去和现在的学术贡献，这些贡献引领和/或启发了重要的技术和商业应用。
