Fuel injection valve operating method for internal-combustion engine, involves exposing component of fuel injection valve to fuel pressure, and controlling electrical operating variable of control element at fuel pressure

摘要

The method involves exposing a component of a fuel injection valve (10) operated by an electromagnetic control element (11) to fuel pressure (P). An electrical operating variable of the control element is controlled at the fuel pressure. A temporal process of an operating current of the control element is evaluated to determine an opening velocity of the fuel injection valve and to determine an opening- and/or a closing time of the fuel injection valve. A value determined by a pressure sensor is verified for the fuel pressure. An independent claim is also included for a control device for a fuel injection valve.
