Description

Technical Field

[0001] The utility model relates to an engine, in particular to an engine cooling water jacket. Background Art

[0002] As users in different fields have higher and higher requirements for engine performance, engine design engineers are also continuously optimizing engine structure and parameters. Engine parameters include power parameters. The greater the engine power, the higher the speed. The greater the power, the higher the heat generated by itself, so the cooling requirements for the engine will also become higher. At present, the cooling water jacket of the engine body is usually a large-cavity type. Because its water channel is large and the coolant flows from bottom to top through the cylinder liner, the flow rate of the coolant is relatively slow; the top position of the cylinder liner and the upper part of the piston burn high heat, but the coolant flows slowly in the large cavity, so the heat dissipation is poor, the heat is too high and concentrated, and it is easy to cause carbon deposits, affecting the working condition of the engine. Long-term use will not only reduce the service life of engine pistons, cylinder liners and other components, but may also cause safety accidents.

[0003] At present, the existing engines have a twin-cylinder structure, while the engine cooling water jacket on the market is only a single-cylinder structure. If the engine cooling water jacket on the market is installed on a twin-cylinder engine, two cooling channels need to be set up, thereby increasing the production cost. Utility Model Content

[0010] Furthermore, in order to allow the coolant to flow into the second cooling water jacket through the first cooling water jacket, the top end of the first cooling water jacket is connected to the second cooling water jacket through a connecting water pipe.

[0011] Furthermore, in order to discharge the coolant after the reaction, a water outlet pipe is fixedly connected to the second cooling water jacket.

[0012] Furthermore, in order to provide coolant to the cooling water tank, a water inlet pipe is fixedly connected to one side of the outer surface of the cooling water tank, and the water inlet pipe is communicated with the cooling cavity.

[0013] Furthermore, in order to facilitate the rotation of the screw rod, the top end of the screw rod extends outside the protruding piece and is fixedly connected to the turntable.

The rotation of the screw rod causes the cross slider to slide toward the bottom of the cavity. The movement of the cross slider causes the connecting rod to move and causes the limit block to slide in the side groove. When the limit block moves into the limit groove, the first cooling water jacket is The first cooling water jacket and the second cooling water jacket are respectively fixedly installed on the two-cylinder engine, so that the engine cooling water jacket cools the two-cylinder engine, effectively avoiding the engine from knocking due to high temperature.
