Abstract

A method and a device for driving at least one solenoid valve used for controlling the injection of fuel into an internal combustion engine. At the start of the driving (activation), the solenoid valve is supplied with a booster voltage that is elevated as compared to that used for the further driving. The energy and/or power output received by the solenoid valve at the start of the driving is able to be influenced as a function of the operating state of the internal combustion engine.
