Abstract: Disclosed is a variable compression ratio device which changes a top dead center of a piston provided in an engine depending on a driving state of the engine. The variable compression ratio device may include: a lower piston reciprocally movable in a cylinder of the engine and connected with a connecting rod to rotate a crankshaft, an operation chamber, an upper piston disposed above the lower piston and partially inserted into the operation chamber, a push plate dividing the operation chamber into upper and lower spaces, a hydraulic pressure chamber which is the lower space, an elastic member provided in the upper space to push the push plate downward, a hydraulic pressure supply unit selectively supplying hydraulic pressure to the hydraulic pressure chamber, and a hydraulic pressure supply pathway connecting the hydraulic pressure supply unit and the hydraulic pressure chamber for supplying the hydraulic pressure.

Abstract: An engine system may include: an engine including a plurality of combustion chambers generating driving torque by burning fuel; an intake line through which fresh air flows into the combustion chambers; an intake manifold for distributing fresh air supplied by the intake line to the combustion chambers; an exhaust line in which exhaust gas exhausted from the combustion chambers flows; a recirculation line branched from the exhaust line and joined to the intake line; a connection pipe disposed at a portion where the recirculation line and the intake line are joined; and a water line connecting the connection pipe and the intake manifold. Condensate water generated at the connection pipe flows in the water line.
