摘要:
An oil circulating control system for an engine includes an engine speed module and a mode selection module. The engine speed module determines a speed of the engine. The mode selection module is configured to select a first pressure mode and a second pressure mode of an oil pump of the engine for the speed. The selection module selects one of the first pressure mode and the second pressure mode based on at least one mode request signal. The mode selection module signals a solenoid valve of a variable oil pressure circuit of the oil pump to transition to a first position when operating in the first pressure mode and to a second position when operating in the second pressure mode.
