There is provided an alcohol internal combustion engine with direct injection and controlled ignition comprising a combustion chamber defined by a reciprocating piston and a flat cylinder head. The cylinder head supports a spark plug and an injector. In the dome of the piston is formed a cup disposed with respect to the intake valve so that the gases are set in rotation in the cup. The spark plug is placed in the cylinder head so that its electrodes are in the vicinity of the periphery of the cup where a rich mixture is produced by stratification at the end of compression. To further improve the stratification and the turbulence, favorable to complete and rapid combustion, a ramp may be provided around a fraction of the periphery of the cup.
