A motor vehicle internal combustion engine has at least one combustion chamber delimited by at least one wall of the internal combustion engine, and at least one injector that is associated with the combustion chamber and that is at least partially accommodated in a receiving opening delimited by a first wall area of the wall extending at least essentially parallel to the axial direction of the injector The injector includes at least one injection opening that opens into the combustion chamber via the receiving opening, in the direction of the combustion chamber the first wall area being directly adjoined by a further wall area of the wall that extends at an angle to the axial direction and which delimits an at least essentially conical area of the receiving opening which expands toward the combustion chamber. Over its length relative to the radial direction of the injector, the further wall area is situated at a distance from the injector and in alignment with the injector, at least in places, and has a cone opening angle in a range of 50 degrees up to and including 90 degrees, the cone opening angle being smaller than a jet angle of the injection jet.
