Abstract

A variable compression ratio apparatus may include an operating unit operated by hydraulic pressure to reciprocate the plunger, an oil control valve controlling hydraulic pressure supplied to the operating unit, an oil supplying unit storing oil supplied to the operating unit via the oil control valve and transmitting the stored oil to the oil control valve, an actuator operating the oil control valve, and a controller connected with the actuator to control the actuator according to an operational state of an engine.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2013-0129966 filed on Oct. 30, 2013, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a variable compression ratio device. More specifically, the present invention relates to a variable compression ratio device that changes the volume of a combustion chamber, thereby changing the compression ratio. Background technique [0004] Generally, the thermal efficiency of a heat engine increases when the compression ratio is higher. Here, the compression ratio is the ratio of the volume of gas flowing to the cylinder and compressed by the piston, and is represented by "cylinder volume at top dead center of piston / combustion chamber volume". That is, as the top dead center of the piston becomes higher, the compression ratio increases. [0005] In the case of a...
