  • Method for computing an ignition angle of an internal combustion engine
    Patent number: 7051712
    Abstract: A method for computing an ignition angle of an internal combustion engine as a function of the operating conditions of the engine and knock signals K, which indicate knocking combustion in the engine. If knock occurs, the ignition angle is retarded. If knock stops for a first period, the ignition angle is advanced again. Advance of the ignition angle is limited on the basis of the first period. If knock stops for a second period, which exceeds the first period, the ignition angle is further advanced.
    Type: Grant

    Date of Patent: May 30, 2006
    Assignee: Robert Bosch GmbH
    Inventors: Anton Kantschar, Robert Sloboda, Rudi Eichhorn, Andreas Meinken, Jochen Goebels, Jan Boettger, Goetz Stelzenmueller, Kai Dierssen, Frederic Gabel
