Computer program speed control for internal combustion engine, controls, e.g. by electronic throttle, intake manifold flow into engine cylinders, to achieve desired engine speed and torque
The inventive system controls an internal combustion (IC) engine having an intake manifold with both an electronically-controlled throttle device, for controlling flow into the manifold, and a further electronically-controlled device such as a variable cam timing system for controlling fuel flow from manifold into cylinders. A target engine speed is obtained, and both electronic devices are controlled in accordance with actual speed, target speed and commands to each device. Independent claims are included for a method of controlling speed of an engine, and an article of manufacture.
