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.
