The rocker arm 7 is mounted on the rocker pin 8, and the rocker arm 7 swings quickly to throw the oil on the cylinder head 1 and the cylinder head cover 3, and then flows back to the oil chamber 6 to complete the cycle. In the whole cycle, the oil cannot be completely isolated from the air and is easily corroded by the moisture in the air. When the moisture ratio in the oil exceeds the standard, the oil emulsification phenomenon will occur, making the oil ineffective in protecting the engine and reducing the service life of the engine.

[0004] Therefore, the applicant has carefully studied motorcycle engines, overcome the deficiencies of the prior art, and developed an engine cylinder head heating structure. Utility Model Content

[0007] The preferred embodiment further comprises a bolt, the cylinder head is provided with a threaded hole, the cylinder cover is provided with a through hole, the bolt passes through the through hole and cooperates with the threaded hole to lock and fix the cylinder head cover on the cylinder head.

[0008] The preferred embodiment further comprises a gasket, wherein the gasket is arranged between the cylinder head and the cylinder head cover.

[0009] Preferably, the height of the oil heating groove is lower than the height of the cylinder head surface.

[0010] Preferably, the cross-section of the oil heating tank is in the shape of an arc with a lower middle and higher sides.

[0011] The preferred embodiment further comprises a rocker pin and a rocker arm, wherein the rocker pin and the rocker arm are cooperatively arranged in the cylinder head.

[0012] After adopting the above scheme, the beneficial effect of the utility model is that: the utility model sets an oil heating tank near the exhaust port of the cylinder head, collects the oil flowing down from the cylinder head and the cylinder head cover and heats the oil, so that the water in the oil is evaporated and discharged from the cylinder head cover ventilation pipe of the cylinder head cover, effectively reducing the emulsification of the oil, the design is simple, and the service life of the engine is improved.

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model provides a heating structure for an engine cylinder head 1, such as Figures 3 to 6 As shown, it includes a cylinder head 1, an oil heating tank 2, a cylinder head cover 3 and a cylinder head cover vent pipe 4. The oil heating tank 2 is arranged on a side of the cylinder head 1 close to the exhaust port 9. The cylinder head cover 3 is locked and fixed on the cylinder head 1. The cylinder head cover 3 is provided with a cylinder head cover vent pipe 4 for discharging water vapor.

[0023] like Figure 4As shown, it also includes a bolt 10, the cylinder head 1 is provided with a threaded hole, the cylinder cover is provided with a through hole, and the bolt 10 passes through the through hole and cooperates with the threaded hole to lock and fix the cylinder head cover 3 on the cylinder head 1. In this embodiment, the bolt 10 is used to lock and fix the cylinder head cover 3 on the cylinder head 1 with the threaded hole, and the connection strength is high. The threaded structure also facilitates the removal of the cylinder head cover 3 from the cylinder head 1.

[0024] like Figure 4 As shown, it also includes a gasket 11, which is arranged between the cylinder head 1 and the cylinder head cover 3. In this embodiment, a gasket 11 is arranged between the cylinder head 1 and the cylinder head cover 3, which can increase the contact area, improve the friction, prevent wear between the cylinder head 1 and the cylinder head cover 3, and improve the service life of the engine.

[0025] like Figure 5 and Figure 6 As shown, the height of the engine oil heating groove 2 is lower than the height of the surface of the cylinder head 1. The engine oil heating groove 2 of this embodiment is arranged on a side of the cylinder head 1 close to the exhaust port 9, and the height of the engine oil heating groove 2 is lower than the height of the surface of the cylinder head 1, which is conducive to collecting the engine oil flowing down from the cylinder head 1 and the cylinder head cover 3 and heating the engine oil.

[0026] like Figure 6 As shown, the cross section of the engine oil heating groove 2 is in an arc shape with a low middle and high sides. The engine oil heating groove 2 of this embodiment adopts a design of a low middle and high sides, so that the bottom of the engine oil heating groove 2 is an arc surface, which is conducive to the deposition of engine oil, increases the heating time of the engine oil, and ensures that the water in the engine oil can be fully evaporated.

[0027] like Figure 2 and Figure 3 As shown, it also includes a rocker pin 8 and a rocker arm 7, which are arranged in cooperation in the cylinder head 1. In this embodiment, a rocker pin 8 and a rocker arm 7 are further arranged in the cylinder head 1, and the rocker arm 7 is installed on the rocker pin 8. Through the rapid swing of the rocker arm 7, the engine oil is thrown onto the cylinder head 1 and the cylinder head cover 3, thereby having the effects of lubricating and cooling various parts in the engine.

[0028] The working process of the utility model is as follows:

[0029] When the engine oil is pressurized by the oil pump 5 and enters the oil channel and flows through the rocker pin 8, the rocker arm 7 is installed on the rocker pin 8. At this time, the rocker arm 7 swings quickly to throw the engine oil on the cylinder head 1 and the rocker head cover, and then the engine oil will flow back to the oil heating tank 2. Since the oil heating tank 2 is arranged on the side of the cylinder head 1 close to the exhaust port 9, this part is the hottest place in the cylinder head 1, so the engine oil can be heated, so that the water in the engine oil evaporates quickly, and the evaporated water vapor is discharged through the cylinder head cover vent pipe 4 arranged on the cylinder head cover 3. Finally, the engine oil will flow back to the oil chamber 6, and the oil in the oil chamber 6 will enter the oil channel through the oil pump 5, and the cycle will be repeated.

[0030] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0031] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
