Control system for an internal combustion engine
First Claim
1. A control system for an internal combustion engine of the type having a movable output member which moves in response to combustion of fuel in at least one chamber in said engine, said control system comprising:
- means responsive to the movement of the output member for generating an operating signal which is a function of the actual velocity and position of the output member from a predetermined position;
means for generating a reference signal which is a function of the actual velocity and position of the output member from a predetermined position;
control means responsive to said operating signal and reference signal for generating a control signal which is a function of the change of velocity of the output member with respect to position of the output member for both said operating signal and said reference signal to control an operating parameter of the engine.

Abstract
A control system for an internal combustion engine wherein the control signal to generate fuel and/or ignition commands is a function of the change of velocity of a movable member, such as a crankshaft flywheel, at a position coupled with the desired velocity of the movable member at that position. The control signal may comprise at least two components wherein the first component represents the difference in magnitude of the peak velocity of the movable member at the two positions and the second signal represents the difference in the two position of the member at which the peak velocities occur.
