Abstract
A compression-ignition type engine in which first fuel of an amount of not more than 30 percent of the maximum amount of fuel is injected in an injection timing region from about 90 degrees to about 20 degrees before top dead center of the compression stroke so that the injected fuel does not break up due to heat or burn until the top dead center of the compression stroke is substantially reached but undergoes an oxidation reaction. Next, second fuel is injected at substantially the top dead center of the compression stroke to start the combustion of the injected fuel.
