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 2):
The control system of  claim 1 , wherein\n the inner surface of the cavity includes, in a cross section including the center axis of the cylinder:\n a lip portion near an opening surface of the cavity in the top surface of the piston; \n a raised center portion rising from a bottom section of the cavity toward the fuel injector; and \n a bulging portion connecting the lip portion to the raised center portion in the form of an arc opening inward toward the center axis, and \n the fuel injected in the first injection flows along the raised center portion from the bulging portion of the cavity to turn back toward the fuel injector from the position offset from the injection axis, the position being offset from the injection axis in a descending direction of the piston.
