Abstract
Under a partial load, a pumping loss is reduced by a stratified combustion to enhance a fuel consumption, and during the maximum output operation, the output is increased by a premixture combustion, and the output of an engine is controlled, thereby enhancing the drivability. Under the partial load, an ignition source is provided in the vicinity of a fuel injection valve, and after the fuel is injected, the mixture is ignited, and a resulting flame is caused by a spray of the fuel to spread into a cylinder, thereby effecting a stratified combustion. When the load increases, so that soot and so on are produced in the stratified combustion, the fuel injection is effected a plurality of times in a divided manner, and a premixture is produced within the cylinder by the front-half injection, and a flame, produced by the latter-half injection, is injected into the cylinder to burn this premixture.
