Initial tightening of a cylinder head assembly on a marine engine block

When attaching the cylinder head to the engine block, to internal combustion engines, the force with which the mounting screws are tightened is of particular importance (in case of too tight a tightening the screws may break, and in the case of too small tightening the fluid may leave the container due to removal. the flanges one to the other). In the case of slow, high-power engines, the engine block is individual, containing a single cylinder shirt. The intermediate solution of the engine block for a group of cylinders is also used. The two-stroke engine chops are more strongly heat demanded, due to the doubling of the number of cycles in the unit of time, respectively by combustion processes in the unit of time. Requesting the cylinder head bolts and other components of the assembly by force due to the pressure developed during the process of gas exchange and combustion in the engine cylinders is a demand with a pulsating character.
