Embodiment 1

[0012] Example 1, such as figure 1 Shown, a kind of engine cylinder block water jacket, it comprises the annular cylinder block water jacket 5 and the water pump 6 that are arranged between the cylinder block and the cylinder liner and are enclosed by the intake side water jacket and the exhaust side water jacket. The water pump outlet 1 cuts into the outlet 4 of the water jacket on the exhaust side. There is a set of water holes on the exhaust side cylinder head on the water jacket on the exhaust side, and a group of water holes on the cylinder head on the intake side on the water jacket on the intake side. , the water hole on the nose bridge area cylinder head is also set in the nose bridge area. A water return port 3 is provided on the other side of the air intake side water jacket corresponding to the water inlet port 4 on the exhaust side water jacket, and is connected with the water pump water inlet port 2 through the water return pipe 7 .

Abstract

The invention provides a water jacket of an engine cylinder, comprising a ring-shaped cylinder water jacket and a water pump that are enclosed by an air inlet side water jacket and an air outlet side water jacket and arranged between the cylinder and a cylinder sleeve; the water outlet of the water pump cuts in the water inlet of the air outlet side water jacket; the air outlet side water jacket is provided with a group of air outlet side cylinder cover water holes; the air inlet side water jacket is provided with a group of air inlet side cylinder cover water holes; and a nose bridge area is also provided with a nose bridge area cylinder cover water hole. The water jacket is characterized in that the air inlet side water jacket corresponding to the other side of air inlet of the air outlet water jacket is provided with a water returning hole and is communicated with the water inlet of the water pump by the water returning hole; as the water outlet of the water pump directly cuts in the water jacket and a water outlet hole on the external wall of the cylinder at the external side of the water jacket of the dead water area is directly communicated with the water inlet of the water pump, the dead water area can be eliminated and the cooling effect can be greatly improved.

Description

technical field [0001] The invention relates to an engine cylinder block water jacket, in particular to a gasoline engine cylinder block water jacket structure. Background technique [0002] As we all know, generally as the power and torque of the engine continue to increase, the heat load of the engine becomes larger and larger, and engine cooling becomes another difficult problem to be overcome when we design the engine. The quality of engine cooling directly affects whether the engine can continue to work normally. With the increase of engine power per liter (now some engines per liter power have exceeded 100KW / L) and the adoption of supercharging technology undoubtedly put forward more challenges for the engine cooling system. high demands. In order to solve the above-mentioned problems, most of them adopt the method of increasing the outlet water flow rate of the water pump and increasing the diameter of the water jacket at present. However, this will increase the int...
