Abstract
Repetitive operations, such as fuel injection and/or ignition timing of a gasoline engine, are controlled by a microprocessor with reference to engine operation parameters that provide electrical inputs in a manner achieving increased efficiency and economy by the provision of an input-output unit that supplies considerable preprocessing of the input signals under control of the microprocessor through the usual data and address buses. Counters are operated to count down from count limit values. The counting rate, as well as the count limit values, are capable of being varied by commands through the data bus, from time to time, so as to make the capabilities of the system adaptable to a wide variety of particular engines. The system is readily programmable for a particular application or machine if a programmable read-only memory (PROM or EPROM) is used for programming the microprocessor.
