ABSTRACT:
According to the method in the two-fuel system, using diesel and alcohol l, the alcohol fuel is continuously supplied with a fuel pump and the diesel fuel is discontinuously supplied with an injection pump by way of separate lines of an injection apparatus. An apparatus, which is suitable for carrying out the method, has a nozzle body (10) with the fluid-controlled needle valves (17; 18a; 18b) which are operated after the opening pressure p.sub.o, which is adjusted at the pressure springs (19; 20a; 20b), is reached by the diesel fuel conveyed through the ring conduit (12) and the pressure channels (13; 14a; 14b), in which case the opening pressure p.sub.o for the needle valve (17) is constantly adjusted to a lower value in respect of the satellite needle valves (18a; 18b). After the needle valve (17) has opened, the diesel fuel, which is under high pressure, flows through the spray apertures (24a; 24b), from which the alcohol fuel, which is conveyed by way of the ring channel (27) and the inlet channels (28a; 28b), is entrained by the diesel fuel according to the Venturi-ejector principle and a two-fuel mixture develops in the spray apertures (24a; 24b). The apparatus can also be equipped with suction slots (31a; 31b) which open out in the narrowest cross section of the spray apertures (24a; 24b) so that by sucking in air out of the combustion chamber (25) a two-fuel two-phase flow develops there.
