Abstract
A method for controlling an injection valve of an internal combustion engine, in particular a piezo-injector during the start-up phase of the internal combustion engine, in particular a common-rail direct-injection engine. The crankshaft of the internal combustion engine is rotated by the starting motor, in particular an electric starting motor. Next, the actuator of the injection valve has an activation signal applied to it such that when maximum needle lift of the actuator is reached, the activation signal is changed. This change of the activation signal is then evaluated.
