Title:
Premixed compression ignition engine controller
Document Type and Number:
Japanese Patent JP6350426
Kind Code:
B2
Abstract:
A control apparatus of a premixed charge compression ignition engine that includes an engine body having a cylinder and causes a mixture gas containing fuel and air to self-ignite inside the cylinder is provided. The apparatus includes a fuel injector for injecting the fuel into the cylinder, a water injector for injecting supercritical water 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 operating range of the engine body is within a water injection range. Within the water injection range, the controller controls the fuel and water injectors to inject the supercritical water or subcritical water between a latter half of compression stroke and an early half of expansion stroke, and to start this injection at a timing that is after the fuel injection and before ignition of the mixture gas.
