Description

Technical Field

[0001] This invention relates to the field of internal combustion engine technology, and in particular to a cylinder head with a dropper-like structure. Background Technology

[0002] An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power-generating device and the entire machine including the power unit.

[0003] like Figure 1 As shown, the integral cylinder head of the internal combustion engine integrates the cylinder head body 2 and the cylinder bore 1 of the cylinder block. This structure is characterized by the absence of a cylinder head gasket. The bottom surface of the cylinder head body 2 is integrated with the wall of the cylinder bore 1, and the connection between the bottoms of the cylinder bores is a T-type connection. The high-pressure combustion gas in the cylinder bore generates pressure on the top surface, and the bottom surface of the cylinder bore experiences significant stress, especially at the root of the cylinder bore, where stress concentration occurs, making it prone to cracking.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a cylinder head with a dropper-like structure, which has a simple and reasonable structure, can avoid stress concentration at the root of the cylinder bore, and improve the heat dissipation capacity at the root of the cylinder bore, thereby solving the problem that the root of the cylinder bore is prone to cracking due to high temperature and high pressure.

[0006] To achieve the above objectives, the present invention provides a cylinder head with a dropper-like structure, comprising: multiple cylinder bores, a cylinder head body, and multiple dropper-like structures. The cylinder head body is disposed above the cylinder bores and seals the cylinder bores. Multiple dropper-like structures are respectively disposed at the roots of the multiple cylinder bores. The multiple cylinder bores and the cylinder head body are integrally formed.

[0007] In one or more embodiments, the cylinder head with a dropper-like structure further includes a plurality of ribs disposed around the plurality of dropper-like structures.

[0008] In one or more embodiments, the dropper-like structure is a dropper-like water jacket.

[0009] In one or more embodiments, multiple dropper-like structures can evenly distribute the force at the root of multiple cylinder bores to multiple ribs.

[0010] In one or more embodiments, multiple droplet-shaped water jackets are used to improve the heat dissipation capacity at the root of multiple cylinder bores.

[0011] In one or more embodiments, the top surfaces of the cylinder bores of the plurality of cylinder blocks are provided with intake and exhaust manifold walls and dropper-shaped ribs, and the dropper-shaped ribs extend to the top surface of the cylinder head body.

[0012] Compared with the prior art, the cylinder head with a dropper-like structure according to the present invention has a simple and reasonable structure, which can avoid stress concentration at the root of the cylinder bore and improve the heat dissipation capacity at the root of the cylinder bore, thereby solving the problem that the root of the cylinder bore is prone to cracking due to high temperature and high pressure.

[0018] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

Figure 3 This is a schematic diagram of the stress structure of the cylinder bore 1 of the cylinder head with a dropper-like structure according to an embodiment of the present invention.

[0021] like Figures 2 to 3As shown, a cylinder head with a dropper-like structure according to an embodiment of the present invention includes: a plurality of cylinder bores 1, a cylinder head body 2, and a plurality of dropper-like structures 3. The cylinder head body 2 covers the cylinder bores 1 and seals the cylinder bores 1. The plurality of dropper-like structures 3 are respectively disposed at the root of the plurality of cylinder bores 1. The plurality of cylinder bores 1 and the cylinder head body 2 are integrally formed.

[0022] In one or more embodiments, the cylinder head with the dropper-like structure further includes a plurality of ribs 4, which are respectively disposed around the plurality of dropper-like structures 3.

[0023] In one or more embodiments, the dropper-shaped structure 3 is a dropper-shaped water jacket.

[0024] In one or more embodiments, multiple dropper-like structures 3 can evenly distribute the force at the root of multiple cylinder bores 1 to multiple ribs 4.

[0025] In one or more embodiments, multiple droplet-shaped water jackets are used to improve the heat dissipation capacity at the root of multiple cylinder bores 1.

[0026] In one or more embodiments, the top surface 5 of a plurality of cylinder bores 1 is provided with intake and exhaust passage walls and dropper-shaped ribs 4, and the dropper-shaped ribs 4 extend to the top surface 5 of the cylinder head body 2.

[0027] In practical applications, the cylinder head of the present invention with a dropper-like structure is integrally formed with the cylinder head body 2 and multiple cylinder bores 1, constituting an integral cylinder head. The bottoms of the multiple cylinder bores 1 are connected by dropper-like structures. The top surface 5 of the cylinder bores 1 is distributed with intake and exhaust passage walls and dropper-like ribs 4, and the ribs 4 extend to the top surface 5 of the cylinder head body 2. The high-temperature gas from combustion in the cylinder bore will generate high pressure and high temperature around the cylinder bore and on the top surface 5. The high-pressure gas will generate huge pressure and a large amount of heat radiation on the top surface 5 of the cylinder bore. The dropper-like structure 3 will evenly distribute the stress at the root to the ribs 4, avoiding stress concentration at the root of the cylinder bore. At the same time, the dropper-like structure 3 (dropper-like water jacket) will also greatly improve the heat dissipation capacity at the root of the cylinder bore, thereby solving the problem of cracks easily generated at the root of the cylinder bore due to high temperature and high pressure.

[0028] In summary, the cylinder head with a dropper-like structure of the present invention has a simple and reasonable structure, which can avoid stress concentration at the root of the cylinder bore and improve the heat dissipation capacity at the root of the cylinder bore, thereby solving the problem that the root of the cylinder bore is prone to cracking due to high temperature and high pressure.
