Method for simulation of an internal combustion engine comprising a number (cyl total ) of cylinders (N cyl ), wherein simulation output parameters (X, X ) of the cylinders (N cyl ) are calculated based on the angular position (Õ CS ) of a crank shaft and which comprises the steps of grouping the cylinders (N cyl ) into a number (g total ) of cylinder groups (Gg), wherein each cylinder group (Gg) comprises a number (i total ) of cylinders (M g,i ); designating one cylinder (M g,1 ) of each group as a master cylinder and all other cylinders (M g,i ) in the same group as slave cylinders; and for each simulation time step calculating current simulation output parameters (X, X ) of the master cylinder for at least one crank-angle position (Õ stor,x ) by simulation of the master cylinder (M g,1 ) and storing the output parameters; and determining simulation output parameters of the slave cylinders (M g,i ) at the current angular position (Õ g,i ) of the respective slave cylinder by mapping of previous simulation output parameters ([X],[X ]), which were stored for the master cylinder (M g,1 ) at at least one previous simulation step of the master cylinder. |
