| description | A method for venting a fuel supply line of a direct-injection internal combustion engine, wherein the fuel supply line has an injector, a high-pressure accumulator upstream of the injector, a flow rate limiting valve between the high-pressure accumulator and the injector for the purposes of limiting a fuel flow rate passing from the high-pressure accumulator to the injector, and a high-pressure pump upstream of the high-pressure accumulator for delivering fuel into the high-pressure accumulator. A pressure in the high-pressure accumulator is regulated by an intake throttle arranged upstream. of the high-pressure pump. In this case, it is provided that the fuel supply line is vented downstream of the high-pressure pump, wherein, during venting operating mode, a passage cross section for the fuel which is smaller than or equal to a predetermined threshold passage cross section is set in the intake throttle. |
