More ammonia can be injected compared to diesel, in the same amount of air, and this compensates for the lower energy content. As the energy content of ammonia is 18.6 MJ/kg, while the energy content of Diesel is 44.11 MJ/kg, the energy content of a stoichiometric air-ammonia mixture is 2.64 MJ/kg vs. the 2.92 MJ/kg of the diesel.
Ammonia (NH 3) plays a vital role in global agricultural systems owing to its fertilizer usage is a prerequisite for all nitrogen mineral fertilizers and around 70 % of globally produced ammonia is utilized for fertilizers [1]; the remnant is employed in numerous industrial applications namely: chemical, energy storage, cleaning, steel industry and synthetic fibers [2].
