[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0041] An embodiment of the present invention provides a vehicle including an engine according to an embodiment of the present invention. The vehicle may be a fuel-powered vehicle, a plug-in hybrid electric vehicle, an extended-range hybrid electric vehicle, or any other type of vehicle having an engine, without limitation. The cooling flow passage of the oil cooler 40 of the engine according to an embodiment of the present invention is drawn out from the cylinder block 10, eliminating the need for additional cooling lines for the oil cooler 40, thus reducing the number of cooling lines for the oil cooler 40 and simplifying the engine structure.

[0042] Please refer to Figure 1 and Figure 2 An embodiment of the present invention provides an engine, including a cylinder block 10.

[0043] The engine also includes Figure 1 and Figure 2 The cylinder head, crankshaft, connecting rod, piston, oil pan, intake and exhaust mechanism, spark plug, etc. are not shown. One end of the cylinder block 10 (such as Figure 1 and Figure 2 The upper end shown in the figure) is connected to the cylinder head, and the other end (as shown in the figure) is connected to the cylinder head. Figure 1 and Figure 2 The crankshaft is connected to a bearing seat (not shown) on the cylinder block 10 near the oil pan. One end of a connecting rod is rotatably connected to the crankshaft. The cylinder block 10 defines a cylinder bore 11, which receives a piston. The other end of the connecting rod is rotatably connected to the piston. The cylinder head defines a combustion chamber (not shown) that communicates with the cylinder bore 11. The cylinder head also houses the intake and exhaust mechanisms and spark plugs.

[0044] During engine operation, the intake mechanism delivers air and fuel into the combustion chamber, spark plug ignition occurs, and the high-temperature, high-pressure gas generated by the fuel combustion pushes the piston to extend and retract within cylinder bore 11. Exhaust gas is then expelled through the exhaust mechanism. To control engine temperature, improve thermal efficiency, and maintain optimal engine operating conditions, embodiments of the present invention also incorporate a temperature control mechanism.

[0045] Specifically, refer to Figures 1 to 3The engine of this embodiment of the present invention further includes a water jacket baffle 20. The cylinder block 10 further defines a mounting groove 12 and a cylinder bore water inlet 13. The mounting groove 12 surrounds the outer periphery of the cylinder bore 11. The water jacket baffle 20 is received in the mounting groove 12 and cooperates with the sidewall of the mounting groove 12 to form a cylinder bore flow channel 213 and a water intake flow channel 223. The cylinder bore water inlet 13 communicates with the cylinder bore water inlet 13 of the water jacket baffle 20.

[0046] The mounting groove 12 can surround all or part of the outer circumference of the cylinder bore 11, meaning it can be connected end-to-end or disconnected. Correspondingly, the water jacket baffle 20 housed in the mounting groove 12 can also be connected end-to-end or disconnected. The mounting groove 12 is formed on the end surface of the cylinder block 10 that connects to the cylinder head. Once the water jacket baffle 20 is installed in the mounting groove 12, it can be flush with the end surface of the cylinder block 10 that connects to the cylinder head.

[0047] The engine may also include a cylinder gasket (not shown). The cylinder gasket is mounted on the end surface of the cylinder block 10 for connection to the cylinder head and seals the mounting groove 12. The cylinder gasket may have corresponding holes as needed to facilitate the circulation of cooling water between the cylinder block 10 and the cylinder head. It should be understood that the cooling water may be a liquid medium such as ordinary water, water containing a coolant, or coolant, without limitation. Hereinafter, the term "cooling water" will be used to refer to the liquid medium.

[0048] Cooling water enters through the cylinder bore water inlet 13. A portion flows into the cylinder bore flow channel 213 to cool the cylinder block 10 (i.e., cylinder bore 11), while a portion enters the oil cooler 40 through the water intake flow channel 223 to cool the oil cooler 40. Because the fuel combustion location is near the junction of the cylinder block 10 and the cylinder head, the temperature at this junction is higher. Therefore, a mounting slot 12 is provided at the end where the cylinder block 10 and the cylinder head meet. The mounting slot 12 is located near the junction of the cylinder block 10 and the cylinder head. The water jacket baffle 20 within the mounting slot 12 cooperates with the sidewalls of the mounting slot 12 to form the cylinder bore flow channel 213, which is closer to the high-temperature area and provides a better cooling effect. The water intake flow channel 223 is connected to the oil cooler 40, allowing the cooling water to flow to the oil cooler 40 through the water intake flow channel 223 to cool the oil cooler 40. This eliminates the need for a separate pipeline connected to the oil cooler 40, simplifying the engine structure.

[0049] refer to Figures 2 to 4 The mounting groove 12 includes a first side wall 121 and a second side wall 122 opposite to each other. The first side wall 121 is close to the cylinder hole 11. The inner circumferential surface 212 of the first portion 215 of the plate body 21 of the water jacket partition 20 is in close contact with the first side wall 121. The inner circumferential surface 212 of the second portion 216 is spaced apart from the first side wall 121 to form a cylinder hole flow channel 213. The water intake isolation rib 22 of the water jacket partition 20 is in close contact with the second side wall 122 to form a water intake flow channel 223.

[0050] The shape of the mounting groove 12 can be adapted to the shape of the cylinder bore 11, and the shape of the water jacket baffle 20 can be adapted to the shape of the mounting groove 12, that is, the shape of the water jacket baffle 20 is adapted to the shape of the cylinder bore 11. Adaptation means that the wall thickness of the structure from the cylinder bore 11 to the mounting groove 12 is roughly equal. Since the inner wall cross-section of the cylinder bore 11 is an arc, the shape of the water jacket baffle 20 is also roughly an arc.

[0051] The cylinder water inlet 13 passes through the outer surface of the cylinder body 10 to the second side wall 122, so that it can be connected with the water intake channel 223, the cylinder water inlet 214 and the cylinder channel 213. The cylinder water inlet 13 can be surrounded by a pipe joint (not shown) on the outer surface of the cylinder body 10 to facilitate connection with the water pump 30.

[0052] refer to Figure 1 and Figure 2 The engine also includes a water pump 30, which is in communication with the cylinder bore water inlet 13. The water pump 30 is directly connected to the cylinder block 10, and the water pump outlet 31 of the water pump 30 is directly in communication with the cylinder bore water inlet 13. This eliminates the need for piping between the water pump 30 and the cylinder block 10, further simplifying the engine structure. The water pump 30 can be a mechanical water pump 30, an electronic water pump 30, or the like, without limitation.

[0053] Optional, reference Figure 1 The engine also includes an oil cooler 40 having a cooling water inlet 41 and a cooling water outlet 42. The cylinder block 10 also has a water intake 15 and a water return 16. The oil cooler 40 is directly connected to the cylinder block 10, with the cooling water inlet 41 communicating with the water intake 15 and the cooling water outlet 42 communicating with the water return 16. This eliminates the need for piping between the oil cooler 40 and the cylinder block 10, simplifying the engine structure.

[0054] Cooling water flows from the water intake 15 into the cooling water inlet 41, passes through the oil cooler 40, and then flows out of the cooling water outlet 42 to the return water port 16. Both the water intake 15 and the return water port 16 penetrate the outer surface of the cylinder block 10 to the second side wall 122 and can be enclosed by pipe joints on the outer surface of the cylinder block 10 to facilitate connection to the oil cooler 40.

[0055] Optional, reference Figure 1 、 Figure 3 and Figure 4 The outer periphery of the plate body 21 of the water jacket partition 20 is also provided with a water intake isolation rib 22 and a water outlet isolation rib 23, which are tightly attached to and enclosed with the second side wall 122 to form a water intake channel 223 and a water outlet channel 231. The water intake channel 223 is connected to the cylinder hole water inlet hole 214, the water intake port 15 is connected to the water intake channel 223, and the return water port 16 is connected to the water outlet channel 231.

[0056] When the cooling water enters the cylinder bore water inlet hole 214 , part of it flows into the cylinder bore flow channel 213 to cool the cylinder body 10 , and the other part flows into the water intake flow channel 223 and flows to the oil cooler 40 to cool the oil cooler 40 . The cooling water of the oil cooler 40 then flows back to the water outlet flow channel 231 .

[0057] refer to Figure 1 The engine also includes a thermostat 50 having a first water inlet 51 and a second water inlet 52. The cylinder block 10 also has a first water outlet 14 and a second water outlet 17. The thermostat 50 is directly connected to the cylinder block 10, with the first water inlet 51 communicating with the first water outlet 14, and the second water inlet 52 communicating with the second water outlet 17. This eliminates the need for piping between the cylinder block 10 and the thermostat 50, simplifying the engine structure. Furthermore, the thermostat 50 having two water inlets allows for more precise control of the cooling water circulation loop, thereby enabling more accurate control of the engine temperature.

[0058] Optional, reference Figure 3 and Figure 4 The plate body 21 of the water jacket partition 20 is also provided with a cylinder hole water outlet 218, and the cylinder hole water outlet 218 is connected to the cylinder hole flow channel 213. Figure 1 and Figure 5 The first water outlet 14 is connected to the cylinder hole water outlet 218, and the second water outlet 17 is connected to the water outlet channel 231.

[0059] Cooling water from cylinder bore flow channel 213 flows into thermostat 50 through cylinder bore water outlet 218, first water outlet 14, and first water inlet 51. Cooling water from outlet flow channel 231 flows into thermostat 50 through second water outlet 17 and second water inlet 52. By controlling the opening and shutoff of cooling water in different paths, thermostat 50 controls whether cooling water flows and the flow rate, thereby controlling engine temperature. The specific structure of thermostat 50 is not limited in this embodiment of the present invention, and its control principles are not described in detail.

[0060] Optional, reference Figure 1 The engine may further include a radiator (not shown), and the thermostat 50 may be connected to the radiator. The radiator is fed with water from the thermostat 50, and the cooling water after passing through the radiator flows back to the thermostat 50.

[0061] The thermostat 50 is also connected to the cylinder head and the water inlet of the water pump 30 (not shown). The cooling water for cooling the cylinder head flows to the thermostat 50, the cooling water for cooling the cylinder bore flow channel 213 for cooling the cylinder body 10 (cylinder bore 11) flows to the thermostat 50, and the cooling water for cooling the oil cooler 40 flows to the thermostat 50. The water in the thermostat 50 is then supplied to the water pump 30, forming a circulation of the cooling water circuit.

[0062] Optional, reference Figure 1 and Figure 5 The water jacket partition 20 may also be provided with a cylinder head water inlet isolation rib 25, which is connected to the cylinder bore water inlet hole 214 and the water intake channel 223 and is used to connect to the cylinder head.

[0063] In this way, the coolant entering the cylinder bore water inlet 13 can not only flow into the cylinder bore flow channel 213 and the water intake flow channel 223, but also flow into the cylinder head through the cylinder head water inlet flow channel 251, so that the cylinder head does not need to be equipped with an independent cooling pipeline, saving the cylinder head cooling pipeline and simplifying the structure of the engine.

[0064] The water jacket partition 20 according to the embodiment of the present invention is described in detail below.

[0065] refer to Figure 1 and Figure 2 An embodiment of the present invention provides a water jacket baffle 20 , which is used to be arranged on the cylinder body 10 .

[0066] In one embodiment, reference Figure 3 and Figure 4 The water jacket partition 20 includes a plate body 21 and a water intake isolation rib 22 .

[0067] The plate body 21 includes an inner peripheral surface 212 and an outer peripheral surface 211 facing each other, and the inner peripheral surface 212 forms a cylinder bore flow channel 213. It should be understood that the cylinder bore flow channel 213 should be completely the mounting groove 12 (refer to Figure 2 ) is enclosed by the first side wall 121, the inner peripheral surface 212 of the plate body 21 and the cylinder gasket. For the convenience of explanation, Figures 3 to 5 The space enclosed by the inner circumferential surface 212 of the plate body 21 is also referred to as the cylinder bore flow passage 213, which will not be further described below. As previously mentioned, the plate body 21 can be an annular structure, connected end to end or disconnected, and has a plate-like shape. When installed in the cylinder body 10, its inner circumferential surface 212 is the surface closest to the cylinder bore 11, and the outer circumferential surface 211 is the surface facing away from the cylinder bore 11 relative to the inner circumferential surface 212.

[0068] The water intake isolating rib 22 is provided on the outer peripheral surface 211, and the water intake isolating rib 22 and the outer peripheral surface 211 together enclose a water intake channel 223, and the water intake channel 223 is used to connect to the device outside the cylinder body 10. The outer part of the cylinder body 10 can be made into an oil cooler 40, or other devices, without limitation. The water intake isolating rib 22 is in the shape of a rib, and can be an integral structure made by an integral molding process with the plate body 21, or connected and fixed to the outer peripheral surface 211 of the plate body 21 by welding or the like, without limitation. The water intake isolating rib 22 protrudes from the outer peripheral surface 211 of the plate body 21. It should be understood that the complete water intake channel 223 should be the mounting groove 12 (refer to Figure 2) is enclosed by the second side wall 122, the outer peripheral surface 211 of the plate body 21 and the water intake isolation rib 22. For the convenience of explanation, Figure 3 and Figure 4 The space enclosed by the outer peripheral surface 211 of the plate 21 and the water intake barrier rib 22 is also referred to as the water intake channel 223, which will not be further described below. The shape and structure of the water intake barrier rib 22 are not limited, and the method of connecting the water intake channel 223 to the exterior of the cylinder body 10 is not limited.

[0069] Plate body 21 further defines a cylinder water inlet hole 214 extending through inner circumferential surface 212 and outer circumferential surface 211. Cylinder water inlet hole 214 communicates with cylinder flow passage 213 and water intake passage 223. The shape of cylinder water inlet hole 214 can be circular, elliptical, or the like, without limitation. The size of cylinder water inlet hole 214 can be adjusted as needed to allow cooling water to enter cylinder flow passage 213 through cylinder water inlet hole 214 and also to enter oil cooler 40 through water intake passage 223.

[0070] Combine Figure 1 The cylinder water inlet 13 is connected to the cylinder water inlet hole 214. Specifically, the cylinder water inlet 13 is connected to the water intake channel 223, which in turn is connected to the cylinder water inlet hole 214. Water pumped by the water pump 30 flows from the cylinder water inlet hole 214 into the cylinder flow channel 213, thereby cooling the cylinder block 10 (cylinder bore 11). The water flows through the water intake channel 223 into the oil cooler 40, thereby cooling the oil cooler 40.

[0071] Currently, conventional engines connect the water pump 30 and the cylinder block 10 through one pipeline, and connect the water pump 30 and the oil cooler 40 through another pipeline. The cylinder block 10 and the oil cooler 40 are each supplied with water by independent pipelines, resulting in the engine requiring more pipelines and a more complex structure.

[0072] In the embodiment of the present invention, a water jacket baffle 20 is provided. The water jacket baffle 20 is provided with a plate body 21 to enclose a cylinder bore flow channel 213. The outer peripheral surface 211 of the water jacket baffle 20 is provided with water intake isolation ribs 22 to enclose a water intake flow channel 223. Only one water jacket baffle 20 is required to cool the cylinder body 10 and the devices outside the cylinder body 10, eliminating the need for pipelines connected to the devices outside the cylinder body 10 and simplifying the structure of the engine.

[0073] Optional, reference Figure 3The water intake isolating rib 22 includes a half-rib 221, which is arranged at the edge of the cylinder bore water inlet hole 214 and half-surrounds the cylinder bore water inlet hole 214. The shape of the half-rib 221 can be an arc, a free curve, a multi-segment line, etc., without limitation. The half-rib 221 can be flush with the inner wall of the cylinder bore water inlet hole 214, or can be offset a certain distance outward relative to the inner wall of the cylinder bore water inlet hole 214, without limitation. The half-rib 221 half-surrounds the cylinder bore water inlet hole 214, that is, the half-rib 221 is not a ring connected end to end, but has an opening. When the cooling water enters the water intake channel 223, the half-rib 221 can guide and limit the water flow, so that the cooling water enters the cylinder bore water inlet hole 214 all the way, flows through the opening of the half-rib 221, and flows into the water intake channel 223 and then into the oil cooler 40.

[0074] Optional, reference Figure 3 and Figure 4 The plate 21 extends along an axis A. Optionally, the plate 21 is annular in shape in a cross section along the axis A. Specifically, the axis A is the axis A of the cylinder bore 11, that is, the plate 21 extends in the axial direction of the cylinder bore 11, and the plate 21 is adapted to the inner wall shape of the cylinder bore 11 and is also annular, so that the cylinder bore flow channel 213 enclosed by the plate 21 can cool the cylinder bore 11 more evenly.

[0075] refer to Figure 1 The cylinder body 10 may have multiple cylinder holes 11, and the multiple cylinder holes 11 are arranged side by side. The corresponding plate body 21 may also be divided into multiple units. The multiple units are sequentially connected in the arrangement direction of the multiple cylinder holes 11, and each unit corresponds to each cylinder hole 11. The cross-section of each unit is generally annular, not connected end to end. It is understood that the cylinder body 10 may also have only one cylinder hole 11, and the plate body 21 may have only one unit.

[0076] refer to Figure 3 The water intake barrier rib 22 also includes a main rib 222, which is connected to the semi-wrapped rib 221 to form a ring-shaped structure connected end to end. The main rib 222 can be an integral structure made by an integral molding process with the plate body 21, or it can be fixedly connected by welding or other methods. The main rib 222 can also be an integral structure or welded to the semi-wrapped rib 221, without limitation. The main rib 222 is connected to the semi-wrapped rib 221 in a ring-shaped shape, and is connected to the second side wall 122 (reference Figure 2 ) is close to the rear water intake channel 223 to form a closed space, which is only connected to the outside through the cylinder hole water inlet hole 214 and the water intake port 15, ensuring that the cooling water flows along the required path.

[0077] refer to Figure 3The main reinforcement 222 includes a first section 2221, a second section 2222 and a third section 2223 connected in sequence. The first section 2221 and the third section 2223 are opposite to each other and spaced apart. The second section 2222 is arc-shaped and smoothly connected to the first section 2221 and the third section 2223. The end of the first section 2221 away from the second section 2222 is smoothly connected to one end of the half-wrapped reinforcement 221, and the end of the third section 2223 away from the second section 2222 is smoothly connected to the other end of the half-wrapped reinforcement 221.

[0078] To enclose and form the water intake channel 223, a first section 2221, a second section 2222, and a third section 2223 are required. The first section 2221 and the third section 2223 are each connected to the ends of the semi-encased reinforcement 221, while the second section 2222 is each connected to the ends of the first section 2221 and the third section 2223 away from the semi-encased reinforcement 221. The first section 2221, the second section 2222, and the third section 2223 can be integrally formed or secured by welding, and can also be integrally formed or secured to the semi-encased reinforcement 221 by welding. The first section 2221 and the third section 2223 are spaced apart. In this way, the water intake channel 223 can be enclosed and formed with a simple structure. The second section 2222 is configured as an arc with smooth connections to facilitate the smooth flow of cooling water and avoid turbulence that affects the cooling effect.

[0079] Optional, reference Figure 3 The first section 2221 and the third section 2223 extend along the circumference of the plate body 21. The circumference of the plate body 21 is the direction of rotation about the axis A. The first section 2221 and the third section 2223 extend along the circumference of the plate body 21, which has a simple structure and allows the cooling water to flow smoothly.

[0080] Optional, reference Figure 1 、 Figure 3 and Figure 4 The plate body 21 is annular, connected end to end, and adapted to the cylinder bore 11 of the cylinder block 10. The annular shape of the plate body 21 is described above and will not be further elaborated here. This allows the cylinder bore flow channel 213 to be annular, connected end to end. Cooling water flowing from the cylinder bore water inlet 214 into the cylinder bore flow channel 213 flows in two opposite directions along the circumference of the plate body 21, ultimately filling the entire cylinder bore flow channel 213. This dissipates heat around the cylinder bore 11 and prevents localized high temperatures.

[0081] Optional, reference Figure 3 and Figure 4The plate body 21 includes a first portion 215 and a second portion 216 connected in the axial direction of the cylinder bore 11. The first portion 215 and the second portion 216 are both annular and connected end to end and connected in the axial direction of the cylinder bore 11. The outer circumferential surface 211 of the first portion 215 is flush with the outer circumferential surface 211 of the second portion 216. The inner circumferential surface 212 of the second portion 216 is recessed relative to the inner circumferential surface 212 of the first portion 215, forming a stepped surface at the end of the first portion 215 facing the second portion 216. The inner circumferential surface 212 of the second portion 216 and the stepped surface together form the cylinder bore flow channel 213. In other words, the first portion 215 is thicker than the second portion 216, and the distance between the second portion 216 and the inner wall of the cylinder bore 11 is greater than the distance between the first portion 215 and the inner wall of the cylinder bore 11, so that the inner circumferential surface 212 of the second portion 216 together forms the cylinder bore flow channel 213.

[0082] Combine Figures 2 to 4 The inner circumferential surface 212 of the first portion 215 is in close contact with the first side wall 121, while the inner circumferential surface 212 of the second portion 216 is spaced apart from the first side wall 121. The end surface of the first portion 215 away from the second portion 216 contacts the bottom of the mounting groove 12. The second portion 216 is closer to the cylinder head than the first portion 215. The cylinder bore flow channel 213 is located near the junction of the cylinder block 10 and the cylinder head. The temperature of the cylinder bore 11 at this location is relatively high, and the cylinder bore flow channel 213 can effectively dissipate heat there. The temperature of the cylinder bore 11 at the location corresponding to the first portion 215 is relatively low, so the heat dissipation requirement is not high and no cooling channel is required.

[0083] Optional, reference Figure 3 and Figure 4 The cylinder water inlet 214 is provided in the first portion 215, and the inner circumferential surface 212 of the first portion 215 is provided with a first connecting groove 217 that connects the cylinder water inlet 214 and the cylinder flow channel 213. Because the thickness of the first portion 215 is thicker than that of the second portion 216, the cylinder water inlet 214 is provided in the first portion 215, which causes less damage to the structure and ensures structural strength. The first connecting groove 217 can extend in the direction of the axis A, and the bottom wall of the first connecting groove 217 can be flush with the inner circumferential surface 212 of the second portion 216. By simply providing the first connecting groove 217, the cylinder water inlet 13 and the cylinder flow channel 213 can be connected, resulting in a simple structure.

[0084] Optional, reference Figure 3 and Figure 4The first portion 215 further defines a cylinder water outlet hole 218 extending through the inner circumferential surface 212 and the outer circumferential surface 211. The inner circumferential surface 212 of the first portion 215 further defines a second connecting groove 219 connecting the cylinder water outlet hole 218 and the cylinder flow passage 213. Similar to the cylinder water inlet hole 214 defined in the first portion 215, the cylinder water outlet hole 218 defined in the first portion 215 minimizes structural damage and ensures structural strength. The second connecting groove 219 can extend in the direction of the axis A, and the bottom wall of the second connecting groove 219 can be flush with the inner circumferential surface 212 of the second portion 216. Simply defining the second connecting groove 219 allows for communication between the cylinder water outlet hole 218 and the cylinder flow passage 213, resulting in a simple structure.

[0085] Combine Figure 1 and Figure 3 The cylinder bore water outlet hole 218 is used to communicate with the first water outlet 14 of the cylinder body 10 to guide the cooling water out of the cylinder bore flow channel 213 and into the thermostat 50.

[0086] Optional, reference Figure 3 The water jacket partition 20 also includes a cylinder hole water outlet isolation rib 24, which is arranged on the outer peripheral surface 211 of the plate body 21. The cylinder hole water outlet isolation rib 24 and the outer peripheral surface 211 of the plate body 21 are enclosed to form a cylinder hole water outlet flow channel 241, and the cylinder hole water outlet hole 218 is connected to the cylinder hole water outlet flow channel 241.

[0087] Combine Figures 1 to 3 The cylinder bore water outlet rib 24 surrounds the outer periphery of the cylinder bore water outlet hole 218 and can be annular, connected end to end, or it can extend to the end surface of the plate body 21 near the cylinder head and be sealed by the cylinder gasket. The cylinder bore water outlet rib 24 is in close contact with the second side wall 122, so that the outer peripheral surface 211 of the plate body 21, the cylinder bore water outlet rib 24, and the second side wall 122 together enclose the cylinder bore water outlet flow channel 241. The first water outlet 14 of the cylinder body 10 is connected to the cylinder bore water outlet flow channel 241. The cooling water flowing from the cylinder bore flow channel 213 through the cylinder bore water outlet hole 218 is collected in the cylinder bore water outlet flow channel 241 and then flows out of the first water outlet 14.

[0088] Optional, reference Figure 1 and Figure 3 The water jacket partition 20 also includes a water outlet flow barrier rib 23, which is arranged on the outer peripheral surface 211 of the plate body 21, and the water outlet flow barrier rib 23 is spaced apart from the water intake flow barrier rib 22. The water outlet flow barrier rib 23 is annular and connected end to end and is enclosed together with the outer peripheral surface 211 to form a water outlet flow channel 231. The water outlet flow channel 231 and the water intake flow channel 223 are used to communicate with the device outside the cylinder body 10.

[0089] The connection method of the outlet isolator 23 and the plate body 21 can refer to the connection method of the water intake isolator 22, which will not be repeated. The outlet isolator 23 is a ring-shaped ring connected end to end, and the outlet flow channel 231 is a closed flow channel.

[0090] Taking the oil cooler 40 and the thermostat 50 as an example, the devices outside the cylinder 10 are combined with Figure 1 and Figure 5 The return water port 16 is connected to the water outlet channel 231, and the second water outlet 17 is also connected to the water outlet 42. The water outlet 42 of the oil cooler 40 is connected to the return water port 16, and the second water inlet 52 of the thermostat 50 is connected to the second water outlet 17. By providing the water outlet isolation rib 23, the water outlet 42 of the oil cooler 40 is connected to the water outlet channel 231 through the return water port 16, and the water outlet channel 231 is further connected to the second water inlet 52 of the thermostat 50 through the second water outlet 17. This saves the connecting pipes between the oil cooler 40 and the thermostat 50, simplifying the engine structure.

[0091] In another embodiment, reference Figure 5 ,and Figure 3 and Figure 4 The illustrated embodiments are basically the same, with the difference being that the water jacket baffle 20 further comprises a cylinder head water inlet isolating rib 25, which is arranged on the outer peripheral surface 211 of the plate body 21, and is connected to the water intake isolating rib 22. The cylinder head water inlet isolating rib 25 and the outer peripheral surface 211 together enclose a cylinder head water inlet flow channel 251, and the cylinder hole water inlet hole 214 is connected to the cylinder head water inlet flow channel 251, and the cylinder head water inlet flow channel 251 is used to connect to the cylinder head.

[0092] Specifically, the connection method between the cylinder head water inlet isolator 25 and the plate body 21 can be referred to as the connection method for the water intake isolator 22 described above, and will not be further described. The cylinder head water inlet isolator 25 has an open structure, comprising two sections, each connected to a half-rib 221 of the water intake isolator 22. In this embodiment, the half-rib 221, which partially surrounds the cylinder bore water inlet 214, is broken away from the main rib 222, forming a notch. The two sections of the cylinder head water inlet isolator 25 are each connected to the two ends of the half-rib 221 at the notch. The two ends of the cylinder head water inlet isolator 25, away from the half-rib 221, extend to the end surface of the plate body 21 near the cylinder head. This ensures that the cylinder head water inlet channel 251 is connected to the cylinder bore water inlet 214 and the water intake channel 223, and the cylinder head water inlet channel 251 can supply water to the cylinder head. The cooling water entering through the cylinder bore water inlet 13 not only flows into the cylinder bore flow channel 213 and enters the water intake flow channel 223 through the cylinder bore water inlet hole 214, but also enters the cylinder head through the cylinder head water inlet flow channel 251, saving the cooling pipeline of the cylinder head and simplifying the structure of the engine.

[0093] After the cooling water enters the oil cooler 40 through the water intake channel 223, the water intake port 15, and the machine cooling water inlet 41 to cool the oil cooler 40, it enters the water outlet channel 231 from the machine cooling water outlet 42 and the return water port 16. The cooling water in the water outlet channel 231 enters the thermostat 50 through the second water outlet 17 and the second water inlet 52. Combined with the aforementioned cylinder head water inlet channel 251, the cooling water enters the cylinder head and flows back to the thermostat 50, and the water in the cylinder bore channel 213 flows to the thermostat 50. The thermostat 50 can control the cooling water in each path to achieve temperature control of the engine.
