Abstract
In an engine () comprising a fuel injector () which performs a post injection after performing a main injection into a cylinder and an exhaust valve () which opens and closes to discharge an exhaust gas, a controller () controls the fuel injector () to start the post injection during a period where a gas velocity in the cylinder along a cylinder axis increases after the exhaust valve () opens. A duration (t) of the post injection is controlled according to a crank angle at which the post injection is to be performed such that a breakup distance (L) at the end of which the injected fuel atomizes does not become larger than a distance (S) from an injection hole () to a cylinder liner (), thereby ensuring that the injected fuel is supplied to an exhaust passage () without adhering to the cylinder liner ().
