1. A computer-implemented method for conserving fuel used by an engine, the method comprising:

  • receiving, by a computer system, a first function comprising a user-specified power output of an engine over a time duration;

    processing, by the computer system, the first function into a second function comprising a directive power output of the engine over the time duration,wherein the second function comprises a plurality of regions of decreased power output relative to the user-specified power output,wherein the second function comprises a plurality of regions of increased power output relative to the plurality of regions of decreased power output,wherein the second function includes cyclical oscillations comprising the plurality of regions of decreased power output and the plurality of regions of increased power output that comprise a same waveform; and

    directing the engine to output power according to the directive power output of the engine over the time duration,wherein, when the engine outputs power according to the directive power output of the engine over the time duration, the engine uses less fuel than the engine would have used if the engine outputted power according to the user-specified power output of the engine over the time duration,wherein the engine remains engaged during the plurality of regions of decreased power output when the engine outputs power according to the directive power output of the engine over the time duration, andwherein the computer system comprises a computer processor and an electronic storage medium.
