Abstract

A compression-ignition type engine in which fuel is injected in a combustion chamber during the compression stroke or intake stroke before 60 degrees before top dead center of the compression stroke and in which the mean particle size of the fuel injected at that time is made a size in which the temperature of the fuel particles reaches the boiling point of the main fuel component, determined by the pressure in the combustion chamber, at substantially the top dead center of the compression stroke. After the injection and until about the top dead center of the compression stroke is reached, evaporation of the fuel by boiling from the fuel particles is prevented and the fuel of the fuel particles boils and evaporates and fuel is ignited and burnt after about the top dead center of the compression stroke.
