Abstract: A system for controlling oil pressure and flow includes an oil pump generating pressurized oil for an engine. Multiple oil system segments each have a feed line. A signal generating control device is in communication with at least one flow control member. The signal generating control device identifies one of multiple operating points of a vehicle engine, selects a pressure and a flow rate of the pressurized oil for the feed line of each of the oil system segments optimizing the pressure and the flow rate of the pressurized oil at the identified one of the operating points, and adjusts a position of the at least one flow control member to deliver the optimized pressure and the flow rate of the pressurized oil. A control system in communication with the signal generating control device directs operation of the flow control member and collects data defining engine working conditions.

Abstract: A method of operating a cooling circuit of an internal combustion engine is disclosed. The engine is equipped with an engine head, and the cooling circuit includes a pump configured to deliver a variable flow of coolant through the cooling circuit. A coolant flow rate to be delivered by the pump is calculated as a function of an engine load, an engine speed and a desired engine head temperature, and the pump is operated to deliver the calculated coolant flow rate.
