摘要： A method for monitoring lambda sensors includes ascertaining a reference value from a magnitude of switching times under operating conditions of a lambda regulation cycle, in which a sensor signal changes from a rich value to a lean value or from a lean value to a rich value. A sensor is classified as functioning correctly if the reference value is less than an associated limit value.

摘要： A valve for the injection of fuel has a valve body (4) which has a recess (5) in which a valve needle (6) that is movable in the axial direction is arranged. The valve needle (6) together with the valve body (4) forms an injection nozzle (7) in a downstream zone. In a closed position the valve needle (6) prevents a stream of fuel from passing through the injection nozzle (7) but otherwise leaves it unimpeded. At a downstream end the injection nozzle (7) has a deflecting element (20) so arranged that a stream of fuel is deflected from taking a predominantly upstream course from the deflecting element (20).
