By using molecular beam sampling mass spectrometry the structure of a NH3/H2/O2/Ar flat premixed flame burning at 50 mbar and with an equivalence ratio equals to one has been determined. Simulated mole fraction profiles have been obtained by using four kinetic mechanisms [1-4] found in the literature but only two of them give results according to the experimental ones. Furthermore, a first study on a spark ignition engine has been performed to define which parameters must be apply to reach the best efficiency as possible and to reduce the formation of pollutants when ammonia is used as fuel in engines.
