SET OF CYLINDER HEAD AND ENGINE BLOCK Russian patent published in 2018 - IPC F02F1/24 F02F1/42 F02B3/06 

FIELD: engines and pumps.

SUBSTANCE: single cylinder head of a cylinder (1) for installation on one of the multiple cylinder sections of a large internal combustion engine comprises a cylinder head body (2) having a gas system side (6), a rod pusher side (8) located opposite the gas system side (6) and a circular surface of the cylinder jacket (4) with a nozzle central hole (10), a pair of inlet holes and a pair of outlet holes. The nozzle central hole is in the center of the circular surface of the cylinder jacket (4). The central axis passes through the nozzle central hole from the gas system side (6) to the rod pusher side (8). The pair of outlet holes and the pair of inlet holes are on the opposite sides with respect to the central axis. A nozzle central recess (18) passes through the cylinder head body (2) to the nozzle central hole. The channel system of gas inlet (20) passes from the gas system side (6) through the cylinder head body (2) to the pair of inlet holes. A gas discharge channel system (22) passes from the pair of outlet holes through the cylinder head body (2) to the gas system side (6). The channel of the rod pusher (28) passes through the cylinder head body (2) on the rod pusher side (8). In total, there are five-cylinder attachment holes (30, 32, 34, 36, 38) passing through the cylinder head body (2) on the outer circular area of the single cylinder head (1). In total, there are five-cylinder attachment holes (30, 32, 34, 36, 38) arranged at a different distance from each other around the nozzle central recess. The engine block for a large internal combustion engine and the large internal combustion engine are also disclosed.

EFFECT: optimised structure of intake air circulation channel and exhaust gas, increased rigidity of the structure.
