1. one kind has a method for operating internal combustion engine that guides the working piston that moves in cylinder at least, and this internal-combustion engine has an intake valve with variable close moment at least, closes and open the suction port of cylinder;

  • And have at least one to have variable the unlatching constantly and the exhaust valve of constant close moment, close and open the relief opening of cylinder, it is characterized in that, internal-combustion engine has a geometrical compression ratio, the full-power compression ratio that the efficient of this geometrical compression ratio during for sub load is best and the antiknock shake is allowed when being higher than full load, internal-combustion engine when sub load with described geometrical compression ratio work, port timing adjusting by intake valve and exhaust valve when full load drops to the full-power compression ratio with compression ratio, and described geometrical compression ratio is between 14;

    1 and 24;

    1.
