Claim:
A feed and control system for an internal combustion engine that is fed with two different fuels, the engine including plural first members ( 26 ) for introducing a first fuel into corresponding explosion chambers and plural second members ( 6 ) for introducing a second fuel into the corresponding explosion chambers, the system comprising: a control unit ( 8 ) the “controls both the” first and second members; a pressure regulator ( 11 ) in a conduit ( 3 ) through which the second fuel is fed from a tank to the second members, said pressure regulator being arranged and adapted to regulate a density and pressure of the second fuel; and control means ( 21 ) for controlling said pressure regulator so that times for introducing the second fuel into the explosion chambers are equal to times for introducing the first fuel into the explosion chambers so that said control unit controls the second members in the same manner as the first members for the same engine operating conditions, said control means being separate from said control unit.
