Cylinder block water jacket capable of improving temperature uniformity

Abstract

The invention relates to a cylinder block water jacket capable of improving the temperature uniformity. The cylinder block water jacket comprises a cylinder block water jacket body arranged in an engine cylinder block; the cylinder block water jacket body is provided with a first cylinder hole water jacket, a second cylinder hole water jacket, a third cylinder hole water jacket and a fourth cylinder hole water jacket connected in sequence; a water inlet is formed in the side surface of one end of the cylinder block water jacket body; the water inlet is positioned on an intake side of an engine, and is connected with the first cylinder hole water jacket; a water outlet is formed in the upper surface of the other end of the cylinder block water jacket body; and the water outlet is positionedat the back end of the engine, and is connected with the fourth cylinder hole water jacket. The cylinder block water jacket is characterized in that nose bridge guide structures are arranged in cylinder block nose bridge areas between two adjacent cylinder hole water jackets; side guide structures are arranged on two sides of the cylinder block nose bridge areas; and bottom guide structures are arranged at the bottoms of two adjacent cylinder hole water jackets. The compactness of the cylinder block structure and the mechanical strength of cylinder holes can be guaranteed; the full cooling ofthe cylinder block nose bridge areas can be guaranteed; and the temperature is uniform.

Description

technical field [0001] The invention relates to an automobile engine, in particular to a cylinder body water jacket capable of reducing the temperature in the nose bridge region of the cylinder body and enhancing the temperature uniformity. Background technique [0002] With the increasing number of new technologies and compactness of engines, the power per liter of engines is gradually increasing, and the heat load of engines is also getting higher and higher. The highest temperature of the engine block is mainly distributed around the cylinder bore, especially the nose bridge area between the two cylinders. Therefore, the cooling of the cylinder water jacket is mainly to cool the cylinder bore, especially the nose bridge area, to prevent local overheating of the cylinder block. Guarantee the power, economy, emission and reliability of the engine. In order to enhance the temperature uniformity, especially reduce the temperature in the nose bridge area of ​​the cylinder blo...
