Abstract

The invention relates to a method for switching off an internal combustion engine and to an internal combustion engine suitable for carrying out said method. Here, after a switching off command for an internal combustion engine, the throttle valve in the air intake system is again opened to enable a relatively large amount of fresh air to be sucked into the combustion chambers of the internal combustion engine. This considerably increases the gas forces in the combustion chambers while the engine slows to a standstill, so that the internal combustion engine can be switched off in a controlled manner. At the same time, products of combustion, which may possibly still be present, are removed from the combustion chambers of the internal combustion engine. As a result, the preconditions for directly starting the internal combustion engine without a starter are created.
