Abstract
The disclosure relates to a method for controlling an internal combustion engine. The internal combustion engine includes a cylinder and a piston, which runs in the cylinder, together delimiting a working chamber. The working chamber is supplied with fresh air from a intake section via an inlet valve and is connected to an exhaust manifold via exhaust valves. The internal combustion engine includes a variable valve actuation system for the actuation of the inlet valves, controlling the opening time and/or the closing time and/or the lift. A strategy for shutting down the internal combustion engine includes controlling the inlet valves of individual or all working chambers in such a way that the transfer of fresh air from the intake section to the exhaust manifold is reduced or avoided and that the drag torque of the internal combustion engine is reduced.
