氨燃料在内燃机的应用技术综述

Review of Ammonic Fuel’s Applications in Internal Combustion Engines

氨作为一种储氢物质,具有单位热值高、便于贮运、廉价易得,完全燃烧不产生有害物质及温室气体等优点,是发动机的理想清洁燃料之一。文章综述了氨射流研究与氨燃料燃烧领域的进展以及氨燃料在发动机中的应用,进一步讨论了氨燃料发动机在今后发展中所面临的挑战,指明了氨燃料发动机未来的趋势由进气道喷射(PFI)转变为缸内直喷(DI)并侧重于压缩点火式(CI)发动机。氨燃料发动机在船运和商用汽车发动机的应用方面都有很广阔的前景。

As a hydrogen carrier,ammonia is one of the ideal clean fuels for internal combustion engines,which has characteristics of high combustion efficiency,convenience of storage and transportation,relatively inexpensive and high accessibility,at the meantime,it also has the advantages of producing none hazardous substances and greenhouse gases when fully combusted.This literature reviewed the progress in researches of ammonia jet and combustion and its applications in combustion engines as a fuel,further discussed what challenges ammonic combustion engines will confront in the future and pointed out the future trends of jet mode of ammonic combustion engines is turning to direct injection(DI)from Port Fuel Injection(PFI)and concentrate on compression ignition(CI)engines.Ammonic combustion engines have a broad application in shipping and commercial engines for automobile.
