CYLINDER HEAD JOINT GAS LEAKAGE MITIGATION
An internal combustion engine system includes a cylinder block, a plurality of bite rings, a cylinder head, and a head gasket. The cylinder block defines a combustion cylinder. The plurality of bite rings encompass the cylinder. The cylinder head is coupled to the cylinder block and covers the combustion cylinder. The head gasket is disposed between the cylinder head and the cylinder block and is structured to engage with the plurality of bite rings. The cylinder head may further include an expansion groove that is disposed between adjacent ones of the plurality of bite rings and extends in a circumferential direction around the cylinder head.
