The Optimizer is an electronic control system that keeps the engine in tune all the time by adjusting its setting continuously for best fuel economy several times each second.
In contrast to the conventional programmed controls, the Optimizer works on the closed-loop principle in which the output influences the input. It has been applied to setting the spark timing and air-fuel ratio in otto engines and injection timing in diesel engines.
Optimizer control is applicable to the adjustment of any setting in any prime mover: right-left, up-down, clockwise-counter clockwise, which influences the power output.
The dramatic advance in microelectronics in the last few years permits the application of Optimizer controls to conventional automobile engines at an amazingly low manufacturing cost.
