Claim:
1. A combustion chamber of a Diesel engine, the combustion chamber comprising: a piston including a piston bottom surface; a cylinder head including a cylinder head surface; and a combustion chamber axis, wherein the piston bottom surface or the cylinder head surface include at least one depression, wherein the at least one depression substantially forms the combustion chamber when the piston is at a top dead center, wherein the at least one depression is arranged in unobstructed facing relation to another of the piston bottom surface and the cylinder head surface, wherein the at least one depression has at least a partially conical shape, wherein an elongated ignition element is arranged along the combustion chamber axis or parallel to the combustion chamber axis, wherein the elongated ignition element is arranged in unobstructed facing relation to the at least one depression in a radial direction of the combustion chamber axis, and wherein the elongated ignition element is configured to initiate a cylindrical ignition impulse in the at least one depression along the combustion chamber axis or parallel to the combustion chamber axis so that the cylindrical ignition impulse propagates essentially only with radial ignition impulse components from the elongated ignition element to the piston bottom surface or the cylinder head surface.
