Abstract
An air compression direct-injection internal combustion engine having a combustion chamber shaped as a body of rotation arranged in a piston is adapted so that in use a rotational motion is imparted to inflowing combustion air, and at upper engine speeds fuel is deposited, by means of a needle nozzle with controllable cross-section, partly in the form of a film on the wall of the combustion space in the direction of the air motion, whereas during idling and at lower engine speeds and loads direct mixing with the combustion air occurs, the fuel injection pressure at the nozzle bore and thus the speed of the fuel jet being maintained constant or substantially constant over the entire operating range of the engine. The speed of the fuel jet is adjusted so that at nominal rotary speed of the engine it is substantially equal to the swirl speed of the combustion air in the vicinity of the fuel jet, and as the rotary speed decreases the speed of the combustion air is reduced substantially to form a speed difference causing friction between air and fuel. The diameter of the injection orifice is selected in accordance with the ratio of engine R.P.M. between idle and nominal speed.
