<P>PROBLEM TO BE SOLVED: To provide a control device for independently controlling an injection amount from an oil jet and a supply amount to a variable valve mechanism, and achieving both of knocking prevention and responsiveness of the variable valve mechanism. <P>SOLUTION: The control device includes: an oil pump 2 driven by the drive shaft of an internal combustion engine; an oil jet 11 injecting a part of lubricating oil flowing in a main gallery 5 to a piston; an oil jet valve 9 controlling the amount of the lubricating oil injected from the oil jet 11; a variable valve mechanism 7 hydraulically driven by the lubricating oil as working oil; a variable valve mechanism valve 6 controlling the amount of the lubricating oil supplied to the variable valve mechanism 7; operation state detecting means 30 to 35 detecting the operation state of the internal combustion engine; and a controller 20 determining which of the oil jet valve 9 or the variable valve mechanism valve 6 is given priority, on the basis of the operation state of the internal combustion engine, and performing opening/closing control of the oil jet valve 9 and the variable valve mechanism valve 6 in accordance with the determination. <P>COPYRIGHT: (C)2012,JPO&INPIT |
