Abstract
A method and an apparatus for setting and/or testing valves, in particular injection valves of an internal combustion engine, are described. A defined activation signal is applied to a valve in order to determine a signal characterizing the flow rate of fuel. A gaseous medium is applied to the valve. A first variable which characterizes the flow rate of the gaseous medium, and/or a second variable, are detected.
