Problems solved by technology
Usually, one or two water holes are used in the design of the body and the cylinder head to connect the cooling water cavity of the cylinder liner with the cooling water cavity of the cylinder head. With the continuous strengthening of the V-type engine, the heat load generated by the engine is getting higher and higher, causing the cylinder liner to , Insufficient and uneven cooling of the cylinder head

The invention belongs to the technical field of engines, and relates to a V-shaped engine cooling system structure. The V-shaped engine cooling system structure comprises an A-row machine body cylinder and a B-row machine body cylinder with the same structures; and cylinder covers are respectively mounted at the tops of the A-row machine body cylinder and the B-row machine body cylinder. The V-shaped engine cooling system structure is characterized in that main water way cavities of the A-row machine body cylinder and the B-row machine body cylinder are connected through a main water way communicating pipe; the A-row machine body cylinder comprises a cylinder jacket; a cylinder jacket ring belt cooling water cavity is formed in the upper part between the cylinder jacket and an engine machine body; a cylinder jacket cooling water cavity is formed in the lower part of the cylinder jacket and the engine machine body; the engine machine body is provided with a cylinder jacket first coolingwater hole, a cylinder jacket second cooling water hole and a cylinder jacket third cooling water hole; and the cylinder jacket ring belt cooling water cavity is arranged at the upper part, near thetop, of the cylinder jacket. The structure cools the part with the highest temperature of the cylinder jacket to the greatest extent during working, is more reasonable in flowing of cooling liquid ofthe cylinder cover cooling water cavity, guarantees enough flow and pressure (flowing speed) of the cooling liquid to satisfy cooling of the outer wall of the cylinder jacket at a combustion chamber part and cooling nearby a cylinder cover exhaust door, and reduces the temperature gradient to guarantee normal operation of pistons and intake and exhaust doors.
Description
technical field [0001] The invention belongs to the technical field of engines and relates to a V-shaped engine cooling system structure. Background technique [0002] In the prior art, the cylinder liner and cylinder head of the V-type engine are cooled by cooling liquid to ensure the normal operation of the piston running in the cylinder liner, prevent the cylinder liner and piston from being stuck or burnt, and ensure that the piston in the cylinder The running intake and exhaust valves operate normally to prevent burns on the joint surfaces of the intake and exhaust valve seats and the intake and exhaust valves on the cylinder head. Usually, one or two water holes are used in the design of the body and the cylinder head to connect the cooling water chamber of the cylinder liner with the cooling water chamber of the cylinder head. With the continuous strengthening of the V-type engine, the heat load generated by the engine is getting higher and higher, causing the cylinde...
