Abstract

A microprocessor based engine control system for controlling heavy engine loads responds to a heavy load control signal (38), and manifold pressure (62), throttle blade position (34) and engine speed (74) signals from various sensors. All of this information is combined with engine control data from a Personality Programmable Read Only Memory (44) in a microprocessor (26) to generate an actuation signal to a delay means (132). The delay operates to hold the heavy load disconnected for a period of time to allow the engine to operate to increase its engine speed. After the delay or in those instances that the speed is great enough, the actuation signal operates a clutch (54) to connect the heavy load to the engine.
