Abstract:
A friction loss management system for an engine, comprises a combustion engine comprising a crankshaft and a plurality of cylinders, a reciprocating piston assembly connected to the crankshaft, a fuel injector connected to an injection controller, an intake valve connected to an intake valve controller, and an exhaust valve connected to an exhaust valve controller. A control unit comprises at least one set of control algorithms configured to receive engine power demand data, and determine a number of cylinders of the plurality of cylinders for deactivation based on the received engine power demand data and further based on sensed or stored friction values for the plurality of cylinders. Determining the number of cylinders of for deactivation minimizes friction between the plurality of cylinders and their respective reciprocating piston assembly by selecting a cylinder combination of active cylinders and deactivated cylinders with the lowest total friction while meeting engine power demand.

Claim (Index 1):
A friction loss management system for an engine, comprising:\n a combustion engine comprising a crankshaft and a plurality of cylinders associated with the crankshaft, each of the plurality of cylinders comprising a respective:\n reciprocating piston assembly connected to the crankshaft; \n fuel injector connected to an injection controller, the fuel injector configured to deactivate and reactivate; \n intake valve connected to an intake valve controller, the intake valve configured to deactivate and reactivate; and \n exhaust valve connected to an exhaust valve controller, the exhaust valve configured to deactivate and reactivate; and \n a control unit comprising at least one processor, at least one memory device, and at least one set of processor-executable control algorithms stored in the at least one memory device, the at least one set of control algorithms configured to:\n receive engine power demand data from one or more power demand inputs; \n receive engine operating parameters comprising at least one of crankshaft rotations per minute and current load on the engine; \n when the received engine power demand data is within one or more specified ranges, determine a number of cylinders of the plurality of cylinders for deactivation based on the received engine power demand data and further based on sensed or stored friction values for the plurality of cylinders; and \n command that the determined number of cylinders of the plurality of cylinders be deactivated, wherein the intake valve controller deactivates the respective intake valves for the determined number of cylinders in response to the command, wherein the exhaust valve controller deactivates the respective exhaust valves for the determined number of cylinders in response to the command, and wherein the injection controller deactivates the respective fuel injectors for the determined number of cylinders in response to the command, \n wherein determining the number of cylinders of the plurality of cylinders for deactivation minimizes friction between the plurality of cylinders and their respective reciprocating piston assembly by selecting a cylinder combination of active cylinders and deactivated cylinders with the lowest total friction while meeting engine power demand.
