Claims17
A method for operating a dual-fuel internal combustion engine (10) comprising a first control unit (SG1) and a further control unit (SG2), wherein the control units (SG1, SG2) are connected to one another of a broadband communication connection (103), and wherein a bidirectional transmission of data takes place between the control units (SG1, SG2) via the broadband communication connection (103), characterized in that each control unit (SG1, SG2) controls the operation of a plurality of injectors (32) and gas valves (40) of at least one cylinder (12) of the internal combustion engine (10).
A multi-fuel control unit (SG1, SG2, SG3) for an internal combustion engine (10), having a plurality of power output stages, characterized in that one part of the power output stages actuates injectors (32) and another part of the power output stages actuates gas valves (40).
