Abstract
A combustion method at a piston combustion engine showing a combustion chamber, in which a piston repeatedly moves in a work producing power stroke followed by an exhaust stroke with intermediate upper respective lower dead centers, in which dead centers the piston motion direction is changed. Air, which will be brought into the engine combustion chamber, is compressed to a certain pressure, whereupon it is brought into the combustion chamber with or without fuel during at least a part of the power stroke. The compressed air with or without fuel is brought into the combustion chamber during such a part of the power stroke determined by a required torque at different engine speeds, from that the piston is situated right before, at or right after the top dead center, and that fuel is combusted with the supplied air during the power stroke.
