Abstract:
1. A control apparatus for a multi-fuel internal combustion engine which is able to be operated by mixed combustion of a plurality of kinds of fuels, said apparatus comprising: a spark plug to carry out ignition to a mixture in a cylinder; a mixing ratio control unit configured to control a mixing ratio of the plurality of kinds of fuels; and an ignition timing control unit configured to control ignition timing of said spark plug based on the mixing ratio of the plurality of kinds of fuels; wherein the mixing ratio of the plurality of kinds of fuels is controlled by said mixing ratio control unit, and the ignition timing of said spark plug is controlled by said ignition timing control unit, in such manner that a required discharge voltage is made equal to or less than a required discharge voltage at the time when only a fuel having the highest relative permittivity among the plurality of kinds of fuels is made to combust.
