An internal combustion engine includes a cylinder head having a cylinder head base, a cylinder wall, and a piston which is movable along a cylinder axis and has a piston crown. A main combustion chamber is formed between the cylinder head base, the cylinder wall, and the piston crown. A precombustion chamber is inserted into a bore of the cylinder head and is fixed relative to the bore in the circumferential direction of the bore. The axis of the bore is at least substantially parallel to the cylinder axis, and a precombustion-type combustion chamber is formed in the precombustion chamber. At least one ring of transfer openings connects the precombustion-type combustion chamber to the main combustion chamber, and in each case, the angle which the transfer opening encloses with the cylinder axis differs for at least two transfer openings of the at least one ring.
