Abstract: The present invention relates to a method for determining a manipulated variable for adjusting an intake manifold pressure in an internal combustion engine on the basis of a target intake manifold pressure, whereby the target intake manifold pressure is corrected as a function of a limit value of the manipulated variable and/or as a function of a variable that has been influenced by the limit value of the manipulated variable. Moreover, the invention relates to a control circuit for carrying out such a method.

Abstract: A method for carrying out a gas exchange in a cylinder of an internal combustion engine is provided. The cylinder is connected to a gas line section via a valve. An actuator adjusts a gas pressure in the gas line section. The valve closes at a fixed point in time in a working cycle of the internal combustion engine in case of a constant torque of the internal combustion engine. The method includes the steps of recognizing a torque change request; determining a target value for the gas pressure in the gas line section in dependence on the torque change request; and determining a variable point in time for closing the valve as a result of the torque change request, wherein the variable point in time is shifted in the working cycle relative to the fixed point in time in dependence on the target value of the gas pressure.
