ABSTRACT:
A direct injection type internal combustion engine includes a centrifugal injector having its port facing a recess formed in a combustion chamber. The injector is arranged such that its axis of injection fails to intersect the central axis of the recess but extends at an inclination with respect to the same. In an embodiment typifying the invention, the following relationship is satisfied: ##EQU1## in which: D designates the maximum distance between facing sides of said recess; wherein with respect to a first transverse plane containing the location of the maximum distance D of said recess and a second plane intersecting said first transverse plane at a right angle, being parallel to the axis of sprays of the swirl injector and containing the center of the recess on the first transverse plane, .beta. designates the distance between the axis of sprays of said swirl injector and a second plane intersecting, at a right angle, a first transverse plane containing the location of the maximum distance D of said recess, said second plane being parallel to the axis of sprays of said swirl injector and containing the center of said recess on said first transverse plane; .theta. designates the angle contained between the axis of sprays of said swirl injector and the first transverse plane; and .theta..sub.s designates the angle of sprays of said swirl injector during fuel injection. The practice of the invention prevents the wall surface of the combustion chamber from being wetted with fuel, thereby improving the combustion phenomena and reducing the specific consumption.
