ABSTRACT:
A method and apparatus for optimizing operational variables of an internal combustion engine, such as the output, or the fuel consumption, by means of the variation of engine variables and the detection of the relative variations thus resulting in the operational variables and a corresponding follow-up of the engine variables which includes a control device, with which the engine variables are preset and are variable at selectable times and/or upon the appearance of certain operational variables or changes in operational variables and the corresponding reactions serve for determining the optimum output and/or the minimum specific fuel consumption. Thus, on the basis of the most precise possible presetting of the various values, a change in the engine variables and a corresponding change in the individual variables in accordance with the particular reaction at that time take place only at fixed times or at fixed combinations of operational variables. A change in the mixture is attained by way of the valve in a bypass channel bypassing the engine throttle valve and the fuel quantity is varied in accordance with the reaction.
