ABSTRACT:
The invention is directed to a method for controlling the idle of an internal combustion engine having an intake channel for conducting air to the engine. The method utilizes sensors for generating signals characterizing the operating state of the engine and for supplying the signals to a control apparatus. A tank-venting valve is provided through which air can be conducted into the intake channel when the tank-venting valve is open. Control quantities are computed in the control apparatus in dependence upon the signals for at least the following: the tank-venting valve, an idle adjuster device, a fuel metering device and an ignition device. The air supplied to the engine is controlled with the aid of the tank-venting valve. The invention is also directed to an arrangement for carrying out the method.
