Abstract:
Method for controlling the combustion process in a combustion engine, comprising at least one cylinder, at least one piston which reciprocates in the cylinder, and is set to reverse in the cylinder at an upper and lower dead center position, and at least one fuel feed device disposed in the cylinder, the method comprising:injecting through said at least one fuel feed device a fuel mixture directly into the cylinder with high kinetic energy such that the fuel or the fuel mixture, on its way into the cylinder, forms a spray and is mixed with cylinder gas compressed in the cylinder forming a fuel/gas mixture; igniting said fuel/gas mixture by compression heat generated in the cylinder only after an at least local mixing of fuel and cylinder gas has occurred; wherein the spray, during the injection step, supplies kinetic energy and controls a spray-internal mixing process between the fuel, or the fuel mixture, and the cylinder gas, and supplies kinetic energy to a large-scale global mixing process; and supplying further kinetic energy to the spray-internal and to the global mixing process as a result of the motion and/or design of the piston.
