Abstract
An internal combustion engine comprising a fuel injector arranged in a combustion chamber. A fuel is injected at a timing when the temperature T of the fuel particles fed into the combustion chamber rises past the vicinity of a minimum temperature of a cool flame region during a compression stroke and reaches a reaction stagnation region near the top dead center of the compression stroke and the fuel particles are dispersed throughout the combustion chamber as a whole near the top dead center of the compression stroke.
