Abstract

An engine system is provided that includes a cylinder, an exhaust flow part, a purifying system, a water injector for injecting supercritical/subcritical water into the cylinder, a water supply passage connected with the water injector and for supplying the water, a first temperature increasing device disposed at a position of the exhaust flow part and for increasing a water temperature, and a second temperature increasing device including a part of the exhaust flow part and a part of the water supply passage, and for increasing a water temperature. The first device increases the water temperature when an exhaust gas temperature passing through the position of the exhaust flow part exceeds a reference temperature. The second device increases the water temperature when an exhaust gas temperature passing through the part of the exhaust flow part is above a water temperature passing the part of the water supply passage.
