Abstract

A system for controlling hydraulic pressure and flow rate of oil in an engine, may include a first solenoid valve disposed in a channel connecting an inlet and an outlet of an oil pump supplying oil from an oil pan to the engine, and an electronic controller controlling the first solenoid valve on the basis of number of revolution of the engine, load of the engine, and temperature of the oil.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0084694 filed on Aug. 31, 2010, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a system for controlling the hydraulic pressure and flow rate of oil in an engine and a control method thereof, more particularly, the present invention relates to a system for controlling the hydraulic pressure and flow rate of oil in an engine, which depends on And the temperature of the oil to control the opening of the solenoid valve installed in each channel, so that the oil is supplied corresponding to the minimum flow rate required by each gallery (gallery), thereby preventing friction loss caused by hydraulic pressure and unnecessary oil consumption , the present invention also relates to the control method of the system. Background technique [0004] Generally, in...
