Abstract
A combustion chamber defined by a recess formed in the top of a piston in the direction of the central axis thereof with its geometry being progressively enlarged in the direction of the recess. The intensities of swirl flow and squish flow are optimized by letting the two flows interact with each other in the upstream side so as to optimize the air flow in the combustion chamber overall. In the meantime, fuel is atomized and injected through a fuel injection nozzle means, which has five or more nozzle holes, toward the side wall of the combustion chamber so as to circumferentially divide the chamber by the fuel sprays into five or more approximately equal sections. Thus, uniform dispersion and distribution of fuel, together with the optimized flow of air, is achieved in the combustion chamber, whereby the air utilization rate is raised and the combustion unburnt particulate matters are decreased.
