ABSTRACT:
The present invention features a modified Saurer type direct injection Diesel engine wherein the fuel injector is offset to one side of the cylinder bore axis and a lip is provided about the upper periphery of the cavity which generates a sufficiently strong squish and reverse squish as to entrain and disperse the fuel (viz., macro-mix) which is injected along the forshortened injection trajectories and prevent wetting of the cavity wall. The lip is further arranged to permit the finely divided low inertia and kinetic energy fuel droplets (micro-mixed) of the fuel which is injected along the elongate injection trajectories to be drawn out of the cavity under the influence of the reverse squish and thus obviate any delay in combustion.
