Abstract
A method is proposed for controlling and regulating an internal combustion engine according to the HCCI combustion method, in which a first fuel in a basic mixture is ignited using a pilot fuel, and in which the fuel quantities of the first fuel and the pilot fuel are changed to represent an operating point of the internal combustion engine. The invention is characterized in that a target combustion energy (VE(SL)) is calculated as a function of a power demand and, based on the target combustion energy (VE(SL)), the fuel quantity of the first fuel and the fuel quantity of the pilot fuel are determined using a distribution factor (CHI), wherein the distribution factor (CHI) is calculated as a function of an actual combustion position (VL(IST)) to a target combustion position (VL(SL)) using a combustion position controller (18).
