Water injector control method for immediate water injection and engine driven by method

Abstract

Disclosed herein are a method of controlling a water injector for immediate water injection and an engine driven by the method. A method of controlling an operation of a water injector for injecting water into the combustion chamber of an engine to which a turbo system for increasing the amount of air by pressing air has been applied includes detecting water pressure applied to a water supply pipe for supplying water to the water injector, stopping an operation of a water supply pump when the detected data reaches a preset reference value, detecting a temperature of water within the water supply pipe for supplying the water to the water injector, and returning the water within the water supply pipe to a water storage tank and driving the water supply pump to supplying new water to the water supply pipe when the detected data deviates from a preset range.
