The object of the present patent finds application in the field of fuels and internal combustion piston engines. The additives here considered consist of metallorganic compounds or solutions of metal salts, which, through thermic decomposition during the normal functioning of the engine, are transformed into ionic solids with the hexaoctahedric structure of the spinel, of the inverted spinel with the disordered structures of the spinel or garnet. They facilitate a particular type of fixed-bed hydrogenating catalytic cracking which works through solid-gas surface catalysis inside the combustion chamber during the normal functioning of the engine. These ionic solids perform the dual function of promoting hydrogenating catalytic cracking at low temperature and acting as combustion catalysts at high temperature; both these conditions obtain in the combustion chamber at every explosion. |
