[0032] like Figures 1 to 4As shown, according to the first aspect of the present invention, a single-cylinder independent cooling type water jacket arrangement structure is provided, which includes a cylinder body 1, a cylinder bore portion 2, a cylinder head 3, a water jacket, a cylinder block cooling pipeline 4 and a cylinder head cooling pipeline 5.
[0033] In the following description, reference will be made to Figures 1 to 4 The specific structures of the above components of the single-cylinder independent cooling type water jacket arrangement structure and the connection relationship of the above components are specifically described.
[0034] like Figure 1 Device Figure 4 As shown, in an embodiment, a plurality of cylinder bore portions 2 may be provided on the upper portion of the cylinder body 1. Intervals may be provided between the plurality of cylinder bore portions 2. A plurality of cylinder heads 3 may be respectively provided on the top of the plurality of cylinder bore portions 2. A water jacket (not shown) may be formed inside the cylinder bore portion 2 and the cylinder head 3. The cylinder block cooling pipe 4 may be respectively connected to the plurality of cylinder bore portions 2 for inputting coolant, and the cylinder head cooling pipe 5 may be respectively connected to the plurality of cylinder heads 3 for outputting coolant. With such an arrangement, the plurality of cylinder bore portions 2 may be cooled independently, so that the plurality of cylinder bore portions 2 do not need to be directly connected, that is, the inter-cylinder water hole structure is eliminated, thereby reducing machining costs.
[0035] Preferably, Figures 1 to 4 As shown, in an embodiment, a rectangular plane may be formed on the top of the cylinder body 1, and multiple cylinder bores 2 may be disposed on the rectangular plane. The cylinder bores 2 may be cylindrical and arranged vertically. The axial direction of the cylinder bores 2 may be perpendicular to the top surface of the cylinder body 1, and the bottom of the cylinder bores 2 may be connected to the top surface of the cylinder body 1.
[0036] Preferably, Figures 1 to 4 As shown, in the embodiment, the cylinder head 3 may be in the shape of a cuboid, and the bottom of the cylinder head 3 may be connected to the top of the cylinder bore 2. The axial direction of the cylinder bore 2 may be perpendicular to the bottom surface of the cylinder head 3, and the cylinder head 3 may be coaxial with the cylinder bore 2.
[0037] Preferably, in an embodiment, the water jacket can be formed as an annular cavity, that is, the water jacket can be not an independent component, but rather a cavity formed within the cylinder bore portion 2 and the cylinder head 3. The water jacket can have an annular cross-section along the radial direction of the cylinder bore portion 2. Preferably, the water jacket can extend vertically within the cylinder bore portion 2 and the cylinder head 3, that is, the annular cavity can extend axially along the cylinder bore portion 2 and the cylinder head 3, thereby connecting the cylinder bore portion 2 and the cylinder head 3, allowing coolant to flow between the cylinder bore portion 2 and the cylinder head 3.
[0038] Preferably, Figures 1 to 4As shown in the embodiment, the cylinder block cooling line 4 may include a first main line 41 and multiple first branch lines 42. The first main line 41 may be connected to the vehicle's water tank, which may supply coolant to the first main line 41 via a water pump. The first main line 41 may be arranged horizontally, and multiple first branch lines 42 may be connected to the first main line 41. The multiple first branch lines 42 may respectively connect the first main line 41 to multiple cylinder bores 2.
[0039] Further, preferably, Figures 1 to 4 As shown, in this embodiment, the first branch line 42 can be arranged perpendicular to the first main line 41. The number of the first branch lines 42 can be equal to the number of cylinder bores 2. Multiple first branch lines 42 can be provided in a one-to-one correspondence with multiple cylinder bores 2. The first branch lines 42 can be connected to the cylinder bores 2 along the radial direction of the cylinder bores 2, thereby supplying coolant into each cylinder bore 2.
[0040] More preferably, Figures 1 to 4 As shown, in this embodiment, a water valve (not shown) can be provided on each of the multiple first branch pipes 42. The water valve is used to control the flow of coolant so that each cylinder bore portion 2 can be cooled independently. Since the multiple cylinder bore portions 2 can be operated independently, the first main pipe 41 can supply coolant to the operating cylinder bore portion 2 separately through each water valve.
[0041] Preferably, Figures 1 to 4 As shown, in this embodiment, the cylinder head cooling circuit 5 may include a second main circuit 51 and multiple second branch circuits 52. The second main circuit 51 may be connected to the vehicle's radiator, allowing coolant in the second main circuit 51 to be delivered to the radiator. The second main circuit 51 may be arranged parallel to the first main circuit 41, and multiple second branch circuits 52 may be connected to the second main circuit 51. The multiple second branch circuits 52 may respectively connect the second main circuit 51 with multiple cylinder heads 3.
[0042] Further, preferably, Figures 1 to 4 As shown, in this embodiment, the second branch line 52 can be arranged perpendicular to the second main line 51. The number of the second branch lines 52 can be equal to the number of cylinder heads 3. Multiple second branch lines 52 can be provided in a one-to-one correspondence with multiple cylinder heads 3. The second branch lines 52 can be connected to the cylinder heads 3 perpendicular to the side surfaces of the cylinder heads 3, so that the coolant in the cylinder heads 3 can be discharged through the second branch lines 52.
[0043] In addition, preferably, Figures 1 to 4As shown, in this embodiment, the upper portion of the water jacket can be connected to the cylinder head cooling line 5, and the lower portion of the water jacket can be connected to the cylinder block cooling line 4. Specifically, the upper portion of the water jacket can be connected to the second branch line 52, and the lower portion of the water jacket can be connected to the first branch line 42. That is, the first branch line 42 and the second branch line 52 are connected through the water jacket. The first branch line 42 inputs coolant into the water jacket, and the coolant exchanges heat in the cylinder bore portion 2 and the cylinder head 3. Finally, the coolant is discharged from the second branch line 52.
[0044] In addition, if Figures 1 to 4 As shown, according to a second aspect of the present invention, an engine is provided, which includes the single-cylinder independent cooling type water jacket arrangement structure as described above.
[0045] During use, the multiple cylinder bores 2 are spaced apart from each other, eliminating the need for inter-cylinder water holes between them, thereby reducing machining costs. Cylinder block cooling lines 4 communicate with each of the cylinder bores 2, supplying coolant to the water jacket. Cylinder head cooling lines 5 communicate with each of the cylinder heads, allowing coolant in the water jacket to be discharged through the cylinder head cooling lines 5, thereby achieving heat exchange. This arrangement effectively reduces water pump power consumption, improves engine thermal efficiency, and ultimately reduces costs.
[0046] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The scope of protection of the present application is not limited thereto. Although the present application has been described in detail with reference to the above-described embodiments, those skilled in the art should understand that any person skilled in the art can modify or easily conceive of changes to the technical solutions described in the above-described embodiments within the technical scope disclosed in the present application, or perform equivalent replacements for some of the technical features thereof.
