  • Publication number: 20210131357
    Abstract: A method for operating a reciprocating piston internal combustion engine in an engine braking mode includes moving an outlet valve of a first cylinder for a first time into a closed position, subsequently for a first time into an open position, subsequently in a direction of the closed position, and subsequently for a second time into the open position. The outlet valve is held open during the moving in the direction of the closed position for such a long time that the first cylinder is filled with gas which flows via an outlet duct out of a second cylinder. The outlet valve is moved, during the moving in the direction of the closed position, into an intermediate position which lies between the open position and the closed position, where from the intermediate position the outlet valve is moved for the second time into the open position.

  • Patent number: 6332056
    Abstract: A video recorder, includes: a filter for performing a comb-filtering operation and supplying a comb-filtered component of a video signal; controllable influencing apparatus for terminating the output of the comb-filtered component and activating instead, the propagation of the non-filtered component; transition detection apparatus for detecting a vertically extending transition and supplying characteristic information upon detection of such a transition; control information generating apparatus, arranged between the transtion detection apparatus and the influencing apparatus, for generating control information enabling the termination of the output of the comb-filtered component and the activation of the propagation of the non-filtered component for a period of time which is longer than possible by means of the characteristic information.
