ABSTRACT:
An air-compressing internal combustion engine which includes a cylinder block, a plurality of cylinders in the cylinder block, a piston reciprocably mounted in the respective cylinders, and a cylinder head disposed on the cylinder block. A precombustion chamber is arranged in the cylinder head and associated with the respective cylinders and a number of approximately radially extending burner holes are provided around a periphery of an end of the precombustion chamber. A depression is arranged in the head of each of the pistons and stellate depressions emanate from the depression in the cylinder head. Each of the stellate depressions ascend continuously in a radially outward direction and a further substantially axially extending burner hole is provided at the end of the precombustion chamber.
