  • Method and system for controlling engine
    Patent number: 10570808
    Abstract: A control system of an engine is provided, which includes a piston formed with a cavity and configured to reciprocate in a cylinder along a center axis of the cylinder, and a fuel injector disposed facing a top surface of the piston and configured to inject fuel along an injection axis. When the piston is located near a top dead center of compression stroke, the fuel injector performs a first injection so that the fuel flows from the fuel injector toward the cavity along the injection axis, collides with an inner surface of the cavity, then flows back toward the fuel injector along the inner surface of the cavity from a position offset from the injection axis. The fuel injector performs a second injection toward the cavity at a timing after the first injection and at which the fuel of the first injection flows back.
