Solution Overview

Problem

Rising fuel costs due to increasing demand for fossil fuels pose significant economic and environmental challenges, as internal combustion engines rely heavily on these resources, leading to inefficient fuel consumption and increased emissions.

Innovation Solution

A fuel conservation system and method that utilizes a programmable logic controller and engine control unit to dampen or cut fuel delivery to internal combustion engines, maintaining horsepower or torque output while reducing fuel consumption through a directive power output strategy, which includes regions of equal or increased power followed by decreased power, and incorporates an electric motor to supplement engine output.

AI summary

Methods and systems are described for conserving fuel used by an engine. In some embodiments a control module processes a user-provided input, as a first function, into a second function. The second function can be used to direct the engine with a directive output power. The directive output power may have regions equal to, greater than, and/or less than what the power output would be if the engine were controlled using the user-provided input.
