ABSTRACT:
The ignition timing, or ignition instant, is determined by generating electric voltages representative of various operating parameters of the internal combustion engine, and modifying these voltages in a function generator to derive ignition control signals. An entirely electronic, or servo-operated adjustment system is responsive to the modified voltages to control the ignition system for proper timing of the ignition spark; in accordance with the present invention, the control system forms part of a closed control loop. In accordance with a feature of the invention, the engine itself forms part of the control loop, in that the effect on an operation parameter of the engine, for example composition of exhaust gases, is evaluated and fed back as an input control quantity to modify the ignition timing.
