Problems solved by technology

The cooling water jacket of the existing engine body has no change in cross-sectional area, the coolant flow rate and flow rate of each part in the cooling water jacket are consistent, and the cooling speed of each part of the cylinder liner is the same, resulting in uneven overall temperature of the cylinder liner
Due to the inconsistent temperature of each part of the cylinder, the degree of expansion of each part is also different, which changes the normal fit clearance between the parts, thus affecting the normal operation of the engine.

Abstract

The invention relates to a water-cooled engine body, in particular to an air cylinder body of a wet-type cylinder liner engine. The air cylinder body comprises a cylinder body and a cylinder liner, and is characterized in that an upper positioning belt and a lower positioning belt are arranged on the cylinder liner; the inner surface of the cylinder body is provided with a convex ring; a cooling water channel formed between the lower positioning belt and the convex ring is used as a first cooling chamber; the cooling water channel formed between the convex ring and the upper positioning belt is used as a second cooling chamber; the cooling water channel formed over the upper positioning belt is used as a third cooling chamber; the cross-sectional area of the second cooling chamber is less than that of the first cooling chamber; and the cross-sectional area of the third cooling chamber is less than that of the second cooling chamber. The invention has the advantages that the air cylinder body can raise the flow velocity of cooling liquid, increase the flow rate of the cooling liquid, raise the heat dissipation rate of a high-temperature area, ensure that the whole cylinder liner is uniform in temperature, guarantee normal fit clearances among parts of the cylinder body and guarantee the normal work of the engine.

Description

technical field [0001] The invention relates to a water-cooled engine body, in particular to a cylinder block of a wet cylinder liner engine. Background technique [0002] The engine body adopts the wet cylinder liner, a cooling water channel is provided between the cylinder liner and the cylinder body, and the cooling water channel is passed through the cooling water to form a cooling water jacket. The wet cylinder liner is in direct contact with the coolant, so the heat dissipation condition is better. When the engine is working, the temperature of each part of the cylinder liner is very inconsistent, and the fire bank of the piston is concentrated on the upper part of the cylinder liner. The cooling water jacket of the existing engine body has no change in cross-sectional area, the coolant flow rate and flow rate of each part in the cooling water jacket are consistent, and the cooling speed of each part of the cylinder liner is the same, resulting in uneven overall tempe...
