Patent ID: 8924126

Claim:
A computer-implemented method, of conserving fuel used by an engine, the computer-implemented method comprising: receiving, by a computer system, as an input 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 has a plurality of regions of decreased engine power output relative to the user-specified power output, wherein the second function has a plurality of regions of increased engine power output relative to the plurality of regions of decreased engine power output, wherein the second function comprises cyclical oscillations between the plurality of regions of decreased engine power output and the plurality of regions of increased engine power output that comprise a same waveform, and wherein, when the engine outputs power equal to the directive power output of the engine over the time duration, the engine consumes less fuel than the engine would have consumed if the engine outputted power equal to the user-specified power output of the engine over the time duration; and outputting, by the computer system, to an engine control module the second function such that the engine outputs power according to the directive power output of the engine over the time duration, wherein the engine remains engaged during the plurality of regions of decreased engine power output when the engine outputs power according to the directive power output of the engine over the time duration; and wherein the computer system comprises a computer processor and an electronic storage medium.
