ABSTRACT:
Operating parameters, such as speed and loading of the engine are converted in electrical signals which are converted into pulse rates, to control counting of an address counter, addressing a read-only (ROM) memory in which characteristics of the engine are stored. To provide easy introduction of additional parameters such as temperature, idle condition, maximum speed, start condition, etc., the final value of an accumulator counter, the number of which at a given time controls the ignition timing, can be changed; further, to simplify the system, the speed and load signals are processed during a portion of the time between successive ignition events, the remaining portion of the time being controlled solely by one of the parameters (preferably speed), thus simplifying the circuitry by providing a transfer switch connecting for the remaining period only the selected (preferably speed) signal to the accumulator counter, the count state of which controls the ignition instant.
