Abstract
A governor for an internal combustion engine suitable for speed regulation of engines driving loads of such character that the power requirements vary more within a recurring cycle than between such cycles is provided by the current invention. Means are provided for speed detection, designation of a number of fixed positions within the load cycle, setting of a power control to specific positions, and memory to store representations of load cycle positions and engine power control positions. A microprocessor computes an engine power control position at each load cycle position and applies the power control position to the engine by controlling the engine power control means.
Claims12
A governor to control the speed of an internal combustion engine, which engine has a driven load of such character as to experience a repetitive load cycle, comprising:
- a means to detect the speed of the engine;
- a means to designate a number of fixed positions within said load cycle;
- a means to set a power control of the engine to specific positions;
- memory means to store representations of load cycle positions and engine power control positions;
- a microprocessor to compute an engine power control position at each load cycle position and to apply said power control position to the engine by controlling the engine power control means.
A governor to control the speed of an internal combustion engine, which engine drives an oilwell pumping unit which has a repetitive load cycle, comprising:
- a means to detect the speed of the engine;
- a means to designate a number of fixed positions within the load cycle of the pumping unit;
- a means to set a power control of the engine to specific positions;
- memory means to store representations of load cycle positions and engine power control positions;
- a microprocessor to compute an engine power control position at each load cycle position and to apply said power control position to the engine by controlling the engine power control means.
