Abstract
The invention relates to the field of engines, in particular to a cooling water jacket structure of an engine. The cooling water jacket structure comprises a cooling water jacket inlet, a cooling water jacket outlet, four cylinder head water jackets, water jackets on four cylinder block gas inlet sides and water jackets on four cylinder block exhaust sides. The cooling water jacket inlet and the cooling water jacket outlet are formed in the cylinder block gas inlet sides; the cooling water jacket inlet is communicated with the water jacket on the first cylinder block exhaust side from the side of a first cylinder block; the water jackets on the cylinder block exhaust sides are communicated; the water jackets on the cylinder block exhaust sides are respectively communicated with the corresponding cylinder head water jackets; the cylinder head water jackets are communicated with the corresponding water jackets on the cylinder block gas inlet sides; the water jackets on the cylinder block gas inlet sides are communicated to the cooling water jacket outlet; an orifice is formed in one side surface of a fourth cylinder block; and a through hole is formed between two adjacent cylinder blocks. The cooling water jacket structure has the advantages that the temperature distribution of a cylinder head is promoted to be more uniform, the engine is more compact, the weight of the engine is lighter, and the flow regulation of the cylinders is more convenient.
Description
Technical field
The present invention relates to engine art, be specifically related to a kind of engine cooling water jacket structure.
Background technique
Engine cooling water jacket purpose of design is uniformly distributed in order to ensure engine water jacket cooling liquid, motor is worked in rational temperature range, it is too high that cooling liquid uneven distribution can cause the component temperature such as cylinder block and head, affect normal matching gap, cylinder holes is out of shape, movement parts is obstructed stuck, reduces the serious consequences such as component mechanical strength.
The design of tradition water jacket is generally U-shaped design, and cooling liquid flows to from cylinder body, and flow out from cylinder cap, its deficiency mainly contains:
Cooling liquid belongs to serial type from each cylinder circulation order, and there is cooling gradient, the such as cooling liquid of four cylinders needs successively by the 3rd cylinder, and 2 cylinders, flow out cylinder cap after 1 cylinder again;
Cooling liquid is imported and exported distant, and cooling system is arranged numerous and diverse.
Therefore, the more difficult control of traditional water jacket design coolant distribution uniformity, heat exchange lack of homogeneity, cooling system layout is at random not compact.
Summary of the invention
The object of the invention is to solve the problem, a kind of engine cooling water jacket structure is provided.
In order to realize object of the present invention, the technical solution used in the present invention is:
A kind of engine cooling water jacket structure, cooling jacket comprises cooling jacket and imports and exports, the cylinder cover water jacket of four cylinders, the air inlet side of the cylinder body of four cylinders and exhaust side water jacket, entering of cooling jacket, outlet is positioned at the air inlet side of cylinder body, cooling jacket import is communicated to the exhaust side water jacket of the first cylinder body from the side of the first cylinder body, be communicated with between the exhaust side water jacket of each cylinder body, the exhaust side water jacket of each cylinder body is communicated to the cylinder cover water jacket of each correspondence respectively, each cylinder cover water jacket is communicated with the air inlet side water jacket of corresponding cylinder body, be communicated with between the air inlet side water jacket of each cylinder body, and be communicated to cooling jacket outlet, the exhaust side water jacket of the 4th cylinder body is communicated to its air inlet side water jacket by the throttle orifice of its side of cylinder block, first and two cylinder bodies, second and three cylinder bodies, side between the 3rd and four cylinder bodies have through hole respectively, these three through holes are communicated with the air inlet side of corresponding cylinder body and the water jacket of exhaust side.
Cooling jacket import is in the air inlet side of the first cylinder body, and cooling jacket outlet is in the air inlet side of the second cylinder body.
Beneficial effect of the present invention is: 1, exhaust side temperature is higher than air inlet side, and cross type water jacket cooling liquid first flows through exhaust side, then flows through air inlet side, exhaust side heat can be passed to air inlet side, impel cylinder cap temperature distribution evenly, it is careful to shunt; 2, cylinder cap each cylinder cooling relatively independent, without temperature gradient, the coefficient of heat transfer evenly; 3, import and export all in cylinder body side, water pump and thermostat can be integrated in one piece, and reduce engine pipelines, make motor compacter, weight is lighter; 4, adopt the shunting of cylinder cap cylinder body, Cooling of Cylinder Head is relatively independent, and rear end throttle orifice regulates, and more convenient when each cylinder flow of adjustment, subsequent design Change cost is low.
