ABSTRACT:
A method for determining adjustment values for a fuel supply device which supplies a fuel mixture to a fuel-burning engine for optimum performance by additionally influencing the preset adjustment values of the fuel supply device itself from values supplied by a storage means containing an engine performance log of adjustment values whereby said performance adjustment values are continuously changed and replaced by values which reflect instantaneous operating engine characteristics. Each replaced value forms the basis for computing a new value upon a change in engine operating characteristics. The apparatus disclosed comprises a fuel supply device, such as a carburetor, which has its adjustment values preset due to its construction, a storage means containing engine performance adjustment values for correcting the preset values of the supply device in response to engine operating characteristics, and a second storage means connected to the fuel supply device and to the first storage means wherein the performance values from said first storage means are continuously adjusted from the engine operating characteristics and stored for use by the fuel supply device for optimum engine operating performance.
