Abstract

An arrangement for air-compressing, direct-injection internal combustion engine having fuel ignition, at least one piston with a combustion chamber having a constricted throat and a pertaining cylinder having a pertaining cylinder head is disclosed. In this arrangement, the fuel injector and the combustion chamber of the piston are in communication with one another, the point of intersection of the longitudinal central axis of the fuel stream with the plane of the pertaining cylinder head which limits the upward movement of the piston is positioned within an imaginary circle having a diameter which is at most 1.1 times the greatest diameter of the combustion chamber, and the fuel injector is adapted to be located from the combustion chamber at a distance of up to about 30% of the greatest diameter of the combustion chamber.
