Abstract

In a control method for an internal combustion engine (1) which has a fuel tank (18), a fuel vapor storage device (25) for storing the escaping fuel vapors and a controllable valve (28) for adjusting the stream of fuel vapors fed to the intake tract (4) during a period of tank ventilation, the valve (28) is controlled in such a way according to the method that the stream of fuel vapors varies during the tank ventilation period. The regeneration of the fuel vapor storage device is intended to be improved thereby.
