ABSTRACT:
In a method for making it easier to start an internal combustion engine having at least one cylinder in which there is at least one piston which is intended to execute an oscillating motion between a top dead center and a bottom dead center, air or a fuel-air mixture is drawn in via an induction line as a result of a movement of the piston toward the bottom dead center. After the bottom dead center has been passed and after the piston has started to move toward the top dead center, the air or the fuel-air mixture is discharged from the cylinder via the induction line. Intake valves are closed at a time which is shifted toward the top dead center. A control element arranged in the induction line closes the induction line after the piston has passed the bottom dead center.
