Abstract
A fuel injection control device causes an injector to execute main injection or pilot injection toward a joint portion, and low penetration injection to inject fuel at timing earlier than the pilot injection in a PILOT region or at timing later than the main injection in an AFTER region. The fuel injection control device causes the low penetration injection to be executed to inject the fuel only in a radial central region of a combustion chamber.
