  • Programmable fuel economy optimizer for an internal combustion engine
    Patent number: 4475506
    Abstract: A self-adaptive fuel control system for an internal combustion engine which provides maximum fuel economy over all conditions of engine operation. Maximum fuel economy is provided by maintaining engine operation at a preselected point on the r.p.m. vs. fuel flow curve, said preselected point being near the border line of lean misfire but at a displacement from the point of misfire sufficient to provide smooth running.
