ABSTRACT:
A compression-ignition type engine in which the engine operating region is divided into a first operating region F of a low load side and a second operating region G of a high load side. When the engine operating state is in the first operating region F, fuel is injected just once before 50 degrees before top dead center of the compression stroke. When the engine operating state is in the second operating region G, first fuel injection I.sub.1 of an amount of not more than 30 percent of the maximum amount of fuel is performed in an injection timing region II and second fuel injection I.sub.2 is performed at substantially the top dead center of the compression stroke.
