FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the cylinder head of an internal combustion engine. Thermally and/or mechanically loaded wall (5) of a fluid-conducting and/or gas structural element includes at least one area due to a load under the threat of cracking, in which, due to operational reasons, the crack may develop from the outer side of the wall into wall (5) of the structural element. Wall (5) includes at least one stopper (6a), (6b), (6c), (6d) of cracks, which in wall (5) of the structural element is located in the area under threat of cracking and/or along the way of cracks and prevents further propagation of cracks. Initiator (4a), (4b), (4c), (4d) of cracks is provided on the outer side of wall (5), which forms a region of the exit of cracks localized in a certain way. Method for manufacturing a crack stopper and a crack initiator and a vehicle is disclosed.
EFFECT: technical result is to prevent locally uncontrolled formation and propagation of cracks.
