In the global environment of carbon emission reduction, diesel engine emissions of carbon dioxide, nitrogen oxide and other harmful gases seriously polluting the environment has been boycotted by governments around the world. Ammonia, as a clean, environment-friendly, easy-to-transport green energy, has broad application prospects. However, due to its poor combustion performance and high calorific value, there are some limitations in its application. In this paper, the mechanism, combustion characteristics and emission characteristics of an engine fueled with ammonia-hydrogen fuel and ammonia-carbon-based fuel are reviewed. Hydrogen fuel and diesel fuel with low ignition energy and fast laminar flame spread characteristics, can make up the shortage of pure ammonia fuel, reduce nitrogen oxide emissions. Among them, hydrogen ammonia fuel has become the mainstream and the most promising fuel, compared with pure ammonia fuel and ammonia diesel fuel has the advantages of clean, low transport costs, fast combustion and so on, will become the future engine main application fuel.
