Abstract
Engine monitor/control microprocessor primarily effective to automatically adjust the engine power setting in a transmission power train in which the transmission drive reduction is variable in ratio, by step change or continuously so, such as for use in farm tractors. The microprocessor adjusts the position of the setting so that engine power set at all levels is produced at the right brake specific fuel consumption for substantially minimum pounds of fuel per horsepower hour, or within a band width thereof if not all that sensitive. Preferably, the microprocessor has a higher priority primary function of also automatically adjusting the transmission drive reduction ratio, for the same purpose but with high sensitivity.
