Abstract
A high compression internal combustion engine is provided wherein corresponding ends of the cylinder liners mounted within cylinder bores formed in the engine block are secured to the cylinder head by a first set of fastening elements threaded into the corresponding ends so as to provide a seal between the head and each liner which is capable of withstanding the combustion pressures generated within each liner, when the engine is in operation. A second set of fastening elements, independent of the first set, secures the cylinder head to the engine block so as to provide a seal between complementary surfaces thereof which is capable of withstanding pressures generated by the circulating cooling medium during operation of the engine.
