Process for ensuring the mixing of a predetermined quantity of liquid or gaseous fuel with the air that is contained in a pre-chamber (1) with one end that is open toward cylinders (6) of an alternative internal-combustion engine, as well as the ignition of said mixture, with the fuel being injected axially from closed end (1c) of pre-chamber (1) by means of an injector (2) that is actuated by a predefined surplus of pressure ( DELTA p) compared to that which is present in pre-chamber (1) itself, said injection is accomplished during the terminal phase of the compression half-cycle, whereby injector (2) and surplus ( DELTA p) are such as to ensure that fuel jet (5) which is injected is completely evaporated and/or mixed with the air that is contained in pre-chamber (1) at the moment when it reaches said open end (1a) of the pre-chamber and which, during its translation motion, mixes with the above-mentioned air according to mixture richness (R) values that can be represented by a predetermined curve (7) that rises from injection point (A) towards center (C) of said open-end (1a) of pre-chamber (1).
