Abstract
Various embodiments may include a method for controlling the residual gas mass remaining in a cylinder of an internal combustion engine after a gas exchange process and/or the purge air mass introduced into an exhaust manifold during a gas exchange process, the method comprising: specifying at least one of a desired residual gas mass or a purge air mass of the cylinder of the internal combustion engine; determining a setpoint position of an actuator which influences the specified mass, based on an inverse residual gas model; and setting the determined setpoint position of the actuator.

A method for controlling the residual gas mass remaining in a cylinder of an internal combustion engine after a gas exchange process and/or the purge air mass introduced into an exhaust manifold during a gas exchange process, the method comprising:
- specifying at least one of a desired residual gas mass or a purge air mass of the cylinder of the internal combustion engine corresponding to an instantaneous operating state of the internal combustion engine identified based on sensor signals including at least one of:
- phase angle of the inlet camshaft, a phase angle of the outlet camshaft, an intake pipe pressure, and a position of a wastegate valve;
- determining a setpoint position of an actuator which influences the specified mass, based on an inverse residual gas model;
- and
- setting the determined setpoint position of the actuator.
A device for controlling the residual gas mass remaining in the cylinder of an internal combustion engine after a gas exchange process and/or the purge air mass introduced into the exhaust manifold of the internal combustion engine during a gas exchange process, the device comprising:
- a processor;
- and
- a memory storing instructions, the instructions, when loaded and executed by the processor, configure the processor to:
- specify at least one of a desired residual gas mass or a purge air mass of the cylinder of the internal combustion engine corresponding to an instantaneous operating state of the internal combustion engine identified based on sensor signals including at least one of:
- phase angle of the inlet camshaft, a phase angle of the outlet camshaft, an intake pipe pressure, and a position of a wastegate valve;
- determine a setpoint position of an actuator which influences the specified mass, based on an inverse residual gas model;
- and
- set the determined setpoint position of the actuator.
