1. An internal combustion engine that compresses an air-fuel mixture containing a fuel and the air in a combustion chamber
and makes the compressed air-fuel mixture subjected to combustion, so as to output power, said internal combustion engine
comprising:
an air-fuel mixture compression mechanism that compresses the air-fuel mixture in said combustion chamber;
a first fuel-air mixture production module that produces a first fuel-air mixture in a cylinder containing a first fuel and
the air at a specific ratio, which avoids auto ignition of the first fuel-air mixture through the compression by said air-fuel
mixture compression mechanism, in said combustion chamber;
a second fuel-air mixture production module that supplies a second fuel, which is different from the first fuel, into a partial
area of said combustion chamber to produce a second fuel-air mixture; and
an ignition module that is configured to ignite the second fuel-air mixture after said first fuel-air mixture is produced
to compress and auto-ignite the first fuel-air mixture.
