Abstract (en)
[origin: DE19648689A1] The present invention pertains to a method and a device for examining and/or adjusting valves, especially injector valves in an internal combustion engine. The valve is activated by means of an agreed control signal in order for a signal (QK) characterizing the fuel flow to be determined. The activating element is a gas. A first quantity (QPN) characterizing the gas flow and/or a second quantity (IAN, IAB) is determined.
