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.

Claim (Index 8):
A method of controlling an engine including a piston formed with a cavity and configured to reciprocate in a cylinder along a center axis of the cylinder, an inner surface of the cavity including, in a cross section including the center axis of the cylinder, a bulging portion bulging outwardly in radial directions of the cavity from an opening surface of the cavity at a top surface of the piston; and a fuel injector disposed facing the top surface of the piston and configured to inject fuel from a nozzle port, a nozzle port center line that is an extension of the center of the nozzle port of the fuel injector intersecting the bulging portion when the piston is located at one of a top dead center of compression stroke and a given position near the top dead center of the compression stroke, the method comprising:\n performing a main injection toward the bulging portion of the cavity at a first timing when the piston is located near the top dead center of the compression stroke, and performing a second injection at a second timing when the nozzle port center line intersects the bulging portion on expansion stroke after a given interval from the end of the main injection.
