CYLINDER HEAD OF INTERNAL COMBUSTION ENGINE WITH LIQUID COOLING Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: cylinder head has cooling space 1 defined by upper bottom 2 and lower (fire) bottom 3 interconnected via outer walls 4, sockets of valves 5,6, and sleeve of the nozzle, separating baffle 8 of space 1 with at least one opening 9 for flowing liquid around the sleeve of the nozzle made in block with walls 4, and intermediate bearing wall 11 constructed as a trancated cone whose grater base is coupled with the upper bottom at sites 13 of its turning into outer walls 4 and lesser base 14 is coupled with baffle 8 in the zone of opening 9 so that the diameter of the cone base is the same as the diameter of the opening made in baffle 8. The distance a between separating baffle 8 and lower bottom 3 decreases in the direction of axis of nozzle sleeve 7. Additional cooling space 15 connected with the cooling space around the nozzle sleeve is made in periphery zone of the lower bottom. EFFECT: improved design. 2 cl, 3 dwg
