Claim 1
Independent Claim
203 words
An air compressing internal combustion engine having ignition means which includes in combination: a cylinder, a cylinder head sealingly connected to said cylinder, a piston reciprocably arranged in said cylinder and provided with a combustion chamber open toward said cylinder head with the inner contour of said combustion chamber being that of a body of revolution, injection nozzle means arranged in said cylinder head and having a nozzle opening directed toward said combustion chamber so that the major portion of the fuel jet injected by said injection nozzle hits the wall of said combustion chamber, and ignition means so arranged in the region of said injection nozzle that at the top dead center position of said piston said ignition means extend into said combustion chamber near said injection nozzle opening both between the pass of the fuel jet ignited already when injected through said nozzle into said combustion chamber on one hand and then said combustion chamber wall on the other hand, the area of impingement of the fuel jet on the combustion chamber wall being located in the lower section of said combustion chamber, the combustion chamber being formed as a spherical combusion chamber having a flattened bottom and a constricted throat.
Claim 2
Dependent Claim
203 words
An air compressing internal combustion engine having ignition means which includes in combination: a cylinder, a cylinder head sealingly connected to said cylinder, a piston reciprocably arranged in said cylinder and provided with a combustion chamber open toward said cylinder head with the inner contour of said combustion chamber being that of a body of revolution, injection nozzle means arranged in said cylinder head and having a nozzle opening directed toward said combustion chamber so that the major portion of the fuel jet injected by said injection nozzle hits the wall of said combustion chamber, and ignition means so arranged in the region of said injection nozzle that at the top dead center position of said piston said ignition means extend into said combustion chamber near said injection nozzle opening both between the pass of the fuel jet ignited already when injected through said nozzle into said combustion chamber on one hand and then said combustion chamber wall on the other hand, the area of impingement of the fuel jet on the combustion chamber wall being located in the lower section of said combustion chamber, the combustion chamber being formed as a spherical combusion chamber having a flattened bottom and a constricted throat.
Claim 3
Dependent Claim
76 words
An engine in combination according to claim 1, in which the impingement area of the fuel jet on the combustion chamber wall is at a distance of from 10 to 15% of the maximum combustion chamber diameter below said diameter and in which viewed in a plane perpendicular to the longitudinal axis of said combustion chamber the angle at the center between said injection nozzle opening and the jet impingement area is from 145° to 160°.
Claim 4
Dependent Claim
60 words
An engine in combination according to claim 1, in which--viewed in a plane perpendicular to the longitudinal axis of said combustion chamber--the fuel jet emitted from the injection nozzle opening and the straight line connecting the injection nozzle opening with the electrode surrounded by said component electrodes are disposed at an angle of from 20° to 30° to each other.
Claim 5
Dependent Claim
25 words
An engine in combination according to claim 1, characterized in that the combustion chamber is arranged eccentrically with regard to the axis of said piston.
Claim 6
Dependent Claim
22 words
An engine in combination according to claim 1, in which said ignition means includes two rod electrodes arranged parallel to each other.
Claim 7
Dependent Claim
37 words
An engine in combination according to claim 1, in which one of said electrodes forming one pole of said ignition means comprises a plurality of component electrodes arranged around to other rod electrode forming the other pole.
Claim 8
Dependent Claim
42 words
An engine in combination according to claim 1, in which the length of said ignition means extending into the combustion chamber at the top dead center position of said piston amounts to from 25 to 30% of the maximum combustion chamber diameter.
Claim 9
Dependent Claim
48 words
An engine in combination according to claim 1, in which the distance between the points where the axes of the ignition means and of the injection nozzle penetrate through the bottom face of said cylinder head amounts to from 25 to 30% of the maximum combustion chamber diameter.
