A feedback-type electronic control system has been developed for optimizing the performance of power producing machines. The device continuously corrects the setting (for instance, spark timing) of the machine for best power, which usually is also the point of best fuel economy. Instead of adjusting the setting from the outside, the engine is enabled to select its own best setting and to correct it continuously to always maximize the power output.
The device consists of four principal components: the dither, which oscillates the setting continuously between narrow preset limits; the celsig, which senses the most minute accelerations; the control, which receives signals from the two; and a servo, which receives commands from the control and adjusts the setting.
