Class Information
Number: 123/406.65
Name: Internal-combustion engines > Spark ignition timing control > Electronic control > Having engine shaft rotational position signal generator (e.g., crank shaft, cam shaft) > Speed responsive timing control > Having counter or addressable memory (e.g., digital timing circuit) > Memory addressed by engine speed or load > With microprocessor
Description: Subject matter wherein the regulating means for varying spark ignition timing includes an integrated computer circuit that performs all of the functions of a central processing unit for retrieving information from the information storage section according to a prestored program to either generate or change an output signal in response to a variation in an input signal, the input signal being indicative of the rate of rotation of the elongated member in the engine block.
