Document Type and Number:
Japanese Patent JP6369409
Kind Code:
B2
Abstract:
A control apparatus of an engine including a cylinder into which a piston is reciprocatably fitted is provided. The apparatus includes a fuel injector for injecting fuel into the cylinder, a water injector for injecting supercritical or subcritical water into the cylinder, and a controller. The controller includes an operating range determining module for receiving a parameter and determining whether an engine operating range is within a water injection range. Within the water injection range, the controller controls the fuel injector to inject a portion of the fuel on an intake stroke or in an early half of compression stroke, and the water injector to inject the water toward a piston crown surface in a period that is between a latter half of the compression stroke and an early half of expansion stroke, after the fuel injection, and before a mixture gas is ignited inside the cylinder.
