Description

Technical Field

[0001] This application relates to the field of engine technology, and more particularly to an engine cylinder head, an engine, and a vehicle. Background Technology

[0002] Engines use pumps such as high-pressure oil pumps to supply lubricating oil or coolant. However, these pumps exert significant forces on the mounting brackets during operation. Current methods integrate the oil pump bracket into the cylinder head cover, resulting in a single-piece cylinder head structure. This necessitates the integrated manufacturing and replacement of the cylinder head cover, leading to higher manufacturing and maintenance costs. Summary of the Invention

[0003] This application provides an engine cylinder head, an engine, and a vehicle, aiming to improve the problems of high manufacturing and maintenance costs.

[0004] An engine cylinder head includes: a cylinder head body, an oil pump bracket, and a cylinder head cover; The oil pump bracket is disposed on one side of the cylinder head body; The cylinder head cover is installed on the top of the oil pump bracket and the cylinder head body; the oil pump bracket and the cylinder head cover together seal the cylinder head body; A seal is disposed between the cylinder head cover and the cylinder head body; and / or, disposed between the oil pump bracket and the cylinder head body; and / or, disposed between the oil pump bracket and the cylinder head cover.

[0005] This application embodiment adopts a modular design based on the oil pump bracket and cylinder head cover. The oil pump bracket and cylinder head cover are independent components. The oil pump bracket and cylinder head cover jointly seal the cylinder head body, and a seal can be set between the three to ensure sealing performance. In the early stage of manufacturing, there is no need for integrated molding, which reduces the requirements of process equipment and process requirements and can reduce manufacturing costs. In the later maintenance, the oil pump bracket and cylinder head cover can be replaced separately, avoiding the need for whole replacement and reducing maintenance costs.

[0006] In some embodiments, the oil pump bracket includes: The connecting part is connected to the cylinder head body; The hollow cavity, connected to the connecting part, is used to house the oil pump.

[0007] In this embodiment, the connecting part is connected to the cylinder head body, so that the connecting part can contact the cylinder head body to withstand the impact of the cylinder head body; the hollow cavity houses the oil pump, withstands the impact of the oil pump during operation, and protects the oil pump to ensure reliable operation of the oil pump, thereby further ensuring the reliability of engine operation.

[0008] In some embodiments, the oil pump bracket is made of aluminum alloy, and / or the cylinder head cover is made of plastic.

[0009] When sealing the cylinder head body with the oil pump bracket and cylinder head cover, only the oil pump bracket needs to withstand the impact, while the cylinder head cover does not need to withstand the impact. Therefore, an aluminum alloy oil pump bracket and a plastic cylinder head cover can be used. Reducing the use of aluminum alloy and using more plastic materials can reduce the weight of the engine cylinder head, achieving weight reduction and lowering the engine's material costs.

[0010] In some embodiments, the oil pump bracket is projected in a triangular shape along the height direction of the cylinder head body.

[0011] In this embodiment, by setting the oil pump bracket to a triangular shape, the area occupied by the oil pump bracket in the lateral direction is reduced, making the engine cylinder head more compact.

[0012] In some embodiments, the contact surface width between the oil pump bracket and the cylinder head body is at least 8 mm.

[0013] In this embodiment of the application, by setting the contact surface width to be at least 8 mm, the sealing performance between the oil pump bracket and the cylinder head body is ensured.

[0014] In some embodiments, the angle between the contact surface of the oil pump bracket and the cylinder head body and the bottom surface of the cylinder head body is no greater than 60 degrees.

[0015] In this embodiment, the angle between the contact surface of the oil pump bracket and the cylinder head body and the bottom surface of the cylinder head body is no greater than 60 degrees; this ensures sealing performance while also taking into account the ability to withstand impact, avoiding wear on the oil pump bracket, and thus reducing later maintenance costs.

[0016] In some embodiments, the engine cylinder head further includes: The first receiving groove is disposed on the oil pump bracket and abuts against the end face of the cylinder head body; The second receiving groove is provided on the cylinder head body and abuts against the end face of the oil pump bracket; The first receiving groove and the second receiving groove are used to accommodate the seal.

[0017] In this embodiment, the sealing element is accommodated by the second receiving groove and the first receiving groove, so that the sealing element can be fixed on the end face of the cylinder head body and the end face of the oil pump bracket, thereby determining the sealing position and further improving the sealing performance.

[0018] In some embodiments, the engine cylinder head further includes: A bracket plug is disposed on the top of the oil pump bracket to seal the oil pump bracket.

[0019] In this embodiment, a bracket plug is used to seal the oil pump bracket, preventing foreign objects from entering the oil pump bracket and causing damage to the oil pump, thereby ensuring the reliability of the oil pump operation.

[0020] An engine includes an engine block, an oil pan, and an engine cylinder head as described above; one end of the engine block is connected to the cylinder head, and the other end is connected to the oil pan.

[0021] A vehicle comprising the engine described above. Attached Figure Description

[0024] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] An engine cylinder head provided in this application includes: a cylinder head body, an oil pump bracket, and a cylinder head cover; The oil pump bracket is disposed on one side of the cylinder head body; The cylinder head cover is installed on the top of the oil pump bracket and the cylinder head body; the oil pump bracket and the cylinder head cover together seal the cylinder head body; A seal is disposed between the cylinder head cover and the cylinder head body; and / or, disposed between the oil pump bracket and the cylinder head body; and / or, disposed between the oil pump bracket and the cylinder head cover.

[0026] This application embodiment adopts a modular design based on the oil pump bracket and cylinder head cover. The oil pump bracket and cylinder head cover are independent components. The oil pump bracket and cylinder head cover jointly seal the cylinder head body, and a seal can be set between the three to ensure sealing performance. In the early stage of manufacturing, there is no need for integrated molding, which reduces the requirements of process equipment and process, and can reduce manufacturing costs. In the later maintenance, the oil pump bracket and cylinder head cover can be replaced separately, avoiding the need for whole replacement and reducing maintenance costs.

[0027] Example 1 Reference Figure 1 The diagram shows a first-view structural diagram of an engine cylinder head according to an embodiment of the present application; the engine cylinder head includes: a cylinder head body 100, an oil pump bracket 200, a cylinder head cover 300, and a seal 600.

[0028] The cylinder head is a core component of an internal combustion engine, located at the top of the engine, and together with the engine cylinder block, forms the combustion chamber. An oil pump bracket 200 is disposed on one side of the cylinder head body 100, and a cylinder head cover 300 is disposed on top of the cylinder head body 100 and the oil pump bracket 200, covering both the cylinder head body 100 and the oil pump bracket 200; the oil pump bracket 200 and the cylinder head cover 300 together seal the cylinder head body 100. A sealing element 600 can be disposed between the cylinder head cover 300 and the cylinder head body 100, that is, it can be disposed on the contact surface between the cylinder head cover 300 and the cylinder head body 100, thereby sealing the connection between the cylinder head cover 300 and the cylinder head body 100. Similarly, the sealing element 600 can be disposed between the oil pump bracket 200 and the cylinder head body 100, that is, it can be disposed on the contact surface between the oil pump bracket 200 and the cylinder head body 100, thereby sealing the connection between the oil pump bracket 200 and the cylinder head body 100. The seal 600 can also be disposed between the oil pump bracket 200 and the cylinder head cover 300, that is, it can be disposed on the contact surface of the oil pump bracket 200 and the cylinder head cover 300, thereby sealing the connection between the oil pump bracket 200 and the cylinder head cover 300. The seal 600 enhances the sealing performance of the connections between various components in the engine cylinder head, preventing oil leakage and thus improving the engine's operational reliability.

[0029] Furthermore, the seal 600 can be a strip structure, with the sealing strip placed on each contact surface, and the sealing strip seals the contact surface by compression.

[0030] This application embodiment adopts a modular design based on the oil pump bracket 200 and the cylinder head cover 300. The oil pump bracket 200 and the cylinder head cover 300 are each an independent component. The oil pump bracket 200 and the cylinder head cover 300 jointly seal the cylinder head body 100, and a sealing element 600 can be set between the three to ensure sealing performance. In the early stage of manufacturing, there is no need for integrated molding, which reduces the requirements of process equipment and process, and can reduce manufacturing costs. In the later maintenance, the oil pump bracket 200 and the cylinder head cover 300 can be replaced separately, avoiding the need for whole replacement and reducing maintenance costs.

[0031] The cylinder head body 100 can be cast from cast iron or aluminum alloy. The oil pump bracket 200 can be made of aluminum alloy and can be a cavity structure made of aluminum alloy, used to mount the oil pump 400 to the engine cylinder head body, and to withstand and buffer the impact of the oil pump 400's operation. The oil pump bracket 200 can mount a high-pressure oil pump.

[0032] Aluminum alloys are alloy materials formed by adding one or more alloying elements (such as copper, magnesium, zinc, silicon, manganese, etc.) to aluminum as the base material. They combine the lightweight properties of aluminum with the strengthening effects provided by alloying elements. The base component is aluminum (Al): the content is usually between 85% and 99%, providing a lightweight and corrosion-resistant matrix. Corresponding alloying elements include, but are not limited to, copper (Cu): which improves strength and hardness (e.g., 2xxx series aluminum alloys), but reduces corrosion resistance; magnesium (Mg): which enhances strength and weldability (e.g., 5xxx series aluminum alloys); zinc (Zn): which significantly improves strength (e.g., 7xxx series aluminum alloys); silicon (Si): which improves casting performance (e.g., 4xxx series aluminum alloys); and manganese (Mn): which refines grains and improves heat resistance (e.g., 3xxx series aluminum alloys). Trace elements such as titanium (Ti) and zirconium (Zr) are used to refine grains, and chromium (Cr) improves resistance to stress corrosion. The specific material composition of the oil pump bracket 200 in this application embodiment can be determined according to actual conditions, and this application embodiment does not limit it.

[0033] The oil pump bracket 200 can be installed on the outer side of the cylinder head body 100, and the two are internally connected. The oil pump 400 carried inside the oil pump bracket 200 can supply oil to the cylinder head body 100 to achieve the functions of lubrication and cooling. Moreover, the oil pump bracket 200 matches the top height of the cylinder head body 100 to facilitate the installation of the cylinder head cover 300. The cylinder head cover 300 can be made of plastic, avoiding the use of aluminum alloy modules as in existing technologies to save material costs and reduce the weight of the engine cylinder head. The cylinder head cover 300 is installed on top of the oil pump bracket 200 and the cylinder head body 100 to shield them, preventing foreign objects from entering and damaging these components. The oil pump bracket 200 and the cylinder head cover 300 together seal the cylinder head body 100, ensuring that oil, water, and air within the cylinder head body 100 are sealed, thus achieving the desired function.

[0034] By modularizing the design of the oil pump bracket 200 and cylinder head cover 300, the oil pump bracket 200 and cylinder head cover 300 are treated as independent components, avoiding the need for integrating the oil pump bracket 200 onto the cylinder head cover as in existing technologies. When the oil pump bracket 200 and cylinder head cover 300 jointly seal the cylinder head body 100, only the oil pump bracket 200 needs to withstand the impact, while the cylinder head cover 300 does not. Therefore, it can be made of plastic, reducing the weight of the engine cylinder head, achieving lightweighting, and lowering the engine's material costs. During later maintenance, the oil pump bracket 200 and cylinder head cover 300 can be replaced separately, avoiding the need for complete replacement and reducing maintenance costs.

[0035] Example 2 Reference Figure 2 The diagram shows a second-view structural view of an engine cylinder head provided in an embodiment of this application; the engine cylinder head includes: a cylinder head body 100, an oil pump bracket 200, a cylinder head cover 300, a seal 600, and a bracket plug 500.

[0036] The cylinder head body 100 can be cast from cast iron or aluminum alloy. The oil pump bracket 200 can be made of aluminum alloy and can be a cavity structure made of aluminum alloy, used to mount the oil pump 400 to the engine cylinder head body, and to withstand and buffer the impact of the oil pump 400's operation. The oil pump bracket 200 can mount a high-pressure oil pump.

[0037] Aluminum alloys are alloy materials formed by adding one or more alloying elements (such as copper, magnesium, zinc, silicon, manganese, etc.) to aluminum as the base material. They combine the lightweight properties of aluminum with the strengthening effects provided by alloying elements.

The specific material composition of the oil pump bracket 200 in this application embodiment can be determined according to actual conditions, and this application embodiment does not limit it.

[0038] The oil pump bracket 200 can be installed on the outer side of the cylinder head body 100, and the two are internally connected. The oil pump 400 carried inside the oil pump bracket 200 can supply oil to the cylinder head body 100 to achieve the functions of lubrication and cooling. Moreover, the oil pump bracket 200 matches the top height of the cylinder head body 100 to facilitate the installation of the cylinder head cover 300. The cylinder head cover 300 can be made of plastic, avoiding the use of aluminum alloy modules as in existing technologies to save material costs and reduce the weight of the engine cylinder head. The cylinder head cover 300 is installed on top of the oil pump bracket 200 and the cylinder head body 100 to shield them, preventing foreign objects from entering and damaging them. The oil pump bracket 200 and the cylinder head cover 300 together seal the cylinder head body 100, ensuring that oil, water, and air within the cylinder head body 100 are sealed. A corresponding support plug 500 can be positioned on top of the oil pump bracket 200, with its dimensions matching the oil pump bracket 200, thus sealing the oil pump bracket 200 and preventing foreign objects from entering and damaging the oil pump 400, thereby ensuring the reliable operation of the oil pump 400. The connection between the support cap 500 and the oil pump bracket 200 can be sealed with a sealing strip or sealant to prevent leakage. A seal 600 can be installed between the cylinder head cover 300 and the cylinder head body 100 to seal the connection between them. The seal 600 can also be installed between the oil pump bracket 200 and the cylinder head body 100 to seal the connection between them. Furthermore, the seal 600 can be installed between the oil pump bracket 200 and the cylinder head cover 300 to seal the connection between them.

[0039] In one embodiment of this application, the engine cylinder head further includes: a first receiving groove disposed on the oil pump bracket 200 and abutting against the end face of the cylinder head body 100; and a second receiving groove disposed on the cylinder head body 100 and abutting against the end face of the oil pump bracket 200. The first and second receiving grooves are used to accommodate a sealing member 600. That is, a portion of the sealing member 600 is embedded in the first receiving groove, and another portion is embedded in the second receiving groove. Thus, when the oil pump bracket 200 and the cylinder head body 100 are sealed, the sealing member 600 closes the gap between the oil pump bracket 200 and the cylinder head body 100. By using the second and first receiving grooves to accommodate the sealing member 600, the sealing member 600 can be fixed to the end face of the cylinder head body 100 and the end face of the oil pump bracket 200, thereby determining the sealing position and further improving the sealing performance.

[0040] In practical applications, in order for the seal 600 to seal stably and effectively, the sealing groove can be 1.5 mm to 2.5 mm in length and be inclined inward at an angle of 30°.

[0041] In some embodiments, reference may be made to Figure 3 and Figure 4The oil pump bracket 200 includes: a connecting portion 210 connected to the cylinder head body 100; and a hollow cavity 220 connected to the connecting portion 210 for housing the oil pump 400. The connecting portion 210 connects to the cylinder head body 100, allowing it to contact the cylinder head body 100 and withstand impacts from it. The hollow cavity 220 houses the oil pump 400, withstands impacts during operation, and protects the oil pump 400, ensuring reliable operation and further guaranteeing engine reliability. The connecting portion 210 can be bolted to the cylinder head body 100, allowing the oil pump bracket 200 to be securely connected to it.

[0042] In some embodiments, the oil pump bracket 200 is triangular in shape when projected along the height direction of the cylinder head body 100. By setting the oil pump bracket 200 to a triangular shape, the area occupied by the oil pump bracket 200 in the lateral direction is reduced, making the engine cylinder head more compact.

[0043] In some embodiments, the contact surface width between the oil pump bracket 200 and the cylinder head body 100 is at least 8 mm; by setting the contact surface width to at least 8 mm, the sealing performance between the oil pump bracket 200 and the cylinder head body 100 is guaranteed. That is, there is at least an 8 mm contact surface width between the oil pump bracket 200 and the cylinder head body 100, and even if leakage occurs, the 8 mm contact surface width can delay or reduce the leakage rate.

[0044] In some embodiments, the angle between the contact surface of the oil pump bracket 200 and the cylinder head body 100 and the bottom surface of the cylinder head body 100 is no greater than 60 degrees. This ensures sealing performance while also taking into account impact resistance, avoiding wear on the oil pump bracket 200, and thus reducing later maintenance costs.

[0045] This application also provides an engine, including an engine block, an oil pan, and an engine cylinder head as described above; one end of the engine block is connected to the cylinder head, and the other end is connected to the oil pan.

[0046] In this embodiment, the engine can be a gasoline engine or a diesel engine. The engine may include an engine block, an oil pan, and an engine cylinder head, which work together to convert chemical energy into mechanical energy. The engine block is the engine's skeleton, typically made of cast iron or aluminum alloy, and contains multiple cylinders, cooling water channels, and lubricating oil channels. The cylinders are cylindrical and are where the pistons reciprocate; cooling water channels surround the cylinders, dissipating heat through coolant circulation; and oil channels connect to the oil pan, providing lubrication for components such as the crankshaft and connecting rods. The operating process includes: In the intake phase, the piston moves downwards, the intake valve opens, and the air-fuel mixture enters the cylinder. In the compression phase, the piston moves upwards to compress the mixture, raising its temperature to its ignition point. In the power phase, the spark plug ignites (in a gasoline engine) or the mixture ignites spontaneously (in a diesel engine), the gas expands, pushing the piston downwards, which in turn drives the crankshaft to rotate and output power via the connecting rod. In the exhaust phase, the piston moves upwards again, the exhaust valve opens, and exhaust gases are expelled from the cylinder. The cycle is repeated; a four-stroke engine requires two crankshaft rotations to complete one cycle. Multi-cylinder engines achieve continuous power output by staggering the firing order of their cylinders. The oil pan, connected below the engine block, holds and supplies lubricating oil. Oil pans can be divided into wet and dry types: wet oil pans are common in passenger vehicles. They store lubricating oil, which is immersed in the oil during crankshaft rotation, lubricating components such as connecting rods and pistons through splashing. An oil stabilizing baffle is installed inside the oil pan to prevent oil from splashing during vehicle vibrations. With a wet oil pan, as the crankshaft rotates, the crankshaft and connecting rod big ends are immersed in the oil, splashing oil to form an oil mist that lubricates cylinder walls, piston pins, and other components. Simultaneously, the oil pump draws oil from the oil pan, passes it through a filter, and delivers it to the main oil passages to lubricate high-speed moving components such as the crankshaft and camshaft. Dry oil pans are mostly used in racing cars or high-performance vehicles. They only collect return oil; the lubricating oil is stored in an external tank and circulated by an oil pump to prevent oil shifting during high-speed cornering, which could lead to insufficient lubrication. A dry sump lubrication system draws oil from an external oil tank via the oil pump, cools and filters it, and then delivers it under high pressure to the various friction surfaces of the engine. The return oil flows directly back to the oil tank, avoiding churning resistance and increasing engine power. The engine cylinder head is located above the engine block and is secured to the engine block with bolts. The engine cylinder head includes: a combustion chamber, forming a sealed space with the piston top, determining the compression ratio and combustion efficiency; a valve mechanism, including intake valves, exhaust valves, valve springs, and the camshaft, controlling the timing of gas entry and exit from the cylinder; cooling water passages and lubrication oil passages, connected to the cylinder block's water passages to form a closed cooling cycle; and oil passages providing lubrication to the valve mechanism. Spark plugs (gasoline engines) or fuel injectors (diesel engines) ignite or inject fuel, initiating combustion. The operation includes: valve timing control, where the camshaft rotates synchronously with the crankshaft via timing gears, driving the valves to open and close at the appropriate times. For example, the intake valve opens before the piston moves downward, extending the intake time; the exhaust valve closes late after the piston moves upward, using inertia to expel exhaust gases.Cooling and lubrication: Coolant flows through the cylinder head water passages to absorb the heat generated by combustion; lubricating oil lubricates components such as valve rocker arms and camshafts through oil passages, reducing wear.

[0047] Based on the above components, the operation process of the four major systems of the engine can be described as follows: Lubrication system: oil pan → oil pump → filter → main oil passage → each friction surface → return oil to oil pan (wet type) or external oil tank (dry type).

[0048] Cooling system: Water pump → cylinder block water passage → cylinder head water passage → radiator → coolant circulation, maintaining engine operating temperature.

[0049] Intake and exhaust system: air filter → intake manifold → cylinder head intake valve → cylinder → cylinder head exhaust valve → exhaust manifold → three-way catalytic converter → exhaust gas emission.

[0050] Fuel system: fuel tank → fuel pump → filter → injector → mixture in cylinder → ignition and power.

[0051] This application also provides a vehicle including the engine described above.
