A method of operating an internal combustion engine of a motor vehicle has the steps of injecting fuel into a combustion chamber in at least two operating types; flowing an air/fuel mixture through a tank ventilation valve and supplying the air/fuel mixture to the combustion chamber; generating an output signal by an integrator, which represents a specific desired fuel rate (fkastes) of the air/fuel mixture flowing through the tank ventilation valve, which is used to take into account respectively a current lambda on the engine; determining a desired fuel proportion (fkates) of the air/fuel mixture flowing through the tank ventilation valve, which represents the desired fuel proportion that should be supplied through the tank ventilation valve; comparing the specific desired fuel rate (fkastes) to the desired fuel proportion (fkates); conveying a comparison result back to the integrator; thereby regulating the specific desired fuel rate (fkastes) to the desired fuel proportion (fkates) of the air/fuel mixture flowing through the tank ventilation valve; also a computer program and a control unit is provided for the inventive method.
