The idea of using ammonia as a fuel is nothing new as its first wellknown use was accomplished in buses within a Belgian fleet during World War II. Although several studies performed during the mid-60's investigated the possibility to consider ammonia as fuel for internal combustion engines (mainly by means of CFR experiments or 0D modelling), ammonia-based combustion engine fueling methods were not ready to be marketed as the use of this toxic molecule still poses major challenges-not only because of its supply and associated safety issues, but also because of its physical characteristics compared to conventional fossil fuels. As a function of the target to supply ammonia either partially in standard engines to limit carbon footprint or to employ it mainly in dedicated engines to reach zero footprint, the technological challenges in dual or sole fuel injection, either in SI or CI engines, could vary if the molecule is used as a source for main power or for auxiliary power units (ie. to extend the range of battery vehicles). Its use would also be a function of the transportation type (medium duty or heavy duty engines for freight, construction, marine transportation, etc.), hence creating a complex scenario. In this chapter new results of advanced researches will be discussed in order to highlight the potential of this future green fuel in internal combustion engines.
