B2

A control system of an engine including a cylinder and a fuel injector, the fuel mixing with air to form a mixture gas and combusting inside the cylinder is provided, which includes a water injector for injecting supercritical water or subcritical water into the cylinder, and a controller. Within a high engine speed operating range, the controller controls the water injector to inject the one of supercritical water and subcritical water into the cylinder for a given period including a top dead center of the cylinder on compression stroke, such that when an injection amount of the one of supercritical water and subcritical water reaches half of a given injection amount, a crank angle of the engine corresponds to a retarding side of the top dead center, the given injection amount being a total amount of the supercritical water or subcritical water injected for the given period.
