Abstract

721,593. Direct injection engines. MOTORUNION, NARODNI PODNIK, and BOTTGER, J. April 12, 1951 [April 12, 1950], No. 8533/51. Class 7 (3). A fuel-injection engine comprises an elipsoidic or bulb-shaped combustion chamber which is arranged in the piston crown and is in communication with the cylinder through a restricted substantially circular transfer opening and a fuel nozzle arranged within the cylinder head which is eccentrically disposed with respect to the main axis of the cylinder and discharges a fuel jet through the transfer opening into the combustion chamber and the axis of the restricted transfer opening the main axis of the combustion chamber and the axis of the cylinder lie in a common plane and the ratio between the distances of the points where each of these axes penetrates a plane coinciding with the top wall of the piston in its upper dead centre position from the point where the longitudinal axis of the fuel nozzle penetrates the top of the piston in its upper dead centre position is substantially the same as the ratio respectively between the diameters of the transfer opening the combustion chamber and the cylinder. In a modification the axis of the fuel nozzle lies within a plane which is parallel to and to a certain extent offset in respect of a plane defined by the centre line of the cylinder and the main axis of the combustion chamber and the distances defined above are taken from the perpendicular projection into the lastmentioned plane of the point where the longitudinal axis of the fuel nozzle penetrates the piston in the upper dead centre position. In Fig. 2 the ratio between the distances of the points where the axes of the transfer opening e<SP>1</SP> of the combustion chamber e and of the cylinder e<SP>0</SP> penetrate a plane coinciding with the top wall of the piston in its upper dead centre position with respect to the point where the axis of the fuel nozzle intersects the piston head in its upper dead centre position is substantially the same as the ratio between the diameters of the transfer opening dl of the combustion chamber d and of the cylinder d<SP>0</SP>. In practice the combustion chamber will not be rectangular in section as shown but will have a rounded shape. Fig. 3 shows a particularly advantageous form of combustion chamber. The modification is shown in Fig. 5. In this modification a rotary movement around the combustion chamber may be imparted to the combustion air. The inlet valve is so disposed that a rotary movement is imparted to the air sucked in during the suction stroke and a uni-directional turbulence is obtained' in the combustion chamber during the compression stroke. In another embodiment (not shown) the axis of the fuel nozzle is inclined to the plane defined by the centre line of the cylinder and the main axis of the combustion chamber.
