A method for equalizing the filling of cylinders of a multi-cylinder internal combustion engine (14) comprising a fully variable mechanical valve train (20) having an adjusting shaft (1) that controls the valve lift of the inlet valves of a cylinder bank and can be rotated together with its rotationally fixed adjusting cam (2) by an electromechanical actuator (3) whereby an equalization of the filling of the individual cylinders is achieved by the fact that filling-dependent engine data are measured by a sensor (16) while the engine (14) is running and are processed using suitable software in a control device (15) into signals with which the actuator (3) rotates the adjusting shaft (1) selectively for each cylinder in keeping with the opening phase and thus regulates the lift and the time cross-section of the individual inlet valves and, as a consequence, also the filling of the individual cylinders to a desired set value.
