Description

Technical Field

[0001] The present application relates to the technical field of vehicle engines, and more particularly, to an engine and a vehicle. Background Art

[0002] In the prior art, the water intake point for a supercharger in an engine is typically the cylinder water jacket or cylinder head. However, in horizontally opposed engines, since the cylinder block has two left and right cylinders, the cooling water from the water pump first flows through the left and right cylinders for cooling before flowing into the cylinder water jacket or cylinder head. When the supercharger draws water from the cylinder water jacket or cylinder head, the cooling water is higher in temperature, thus reducing the supercharger's cooling effect. Summary of the Invention

[0003] Embodiments of the present application provide an engine and a vehicle that can solve or improve the technical problem that the temperature of cooling water flowing out of the cylinder water jacket for supercharger heat dissipation is high, resulting in poor cooling effect of the supercharger.

[0004] An engine according to an embodiment of the present application includes a supercharger, an oil sump, and a cylinder block. The oil sump includes a main body, the main body having a water intake passage, the water intake passage including a first water inlet, a first water outlet, and a second water outlet, the first water inlet being adapted to communicate with a water pump; the cylinder block having a second water inlet, the second water inlet communicating with the first water outlet, and the second water outlet communicating with the supercharger.

[0005] In this way, by providing a water intake channel on the oil pan, the water intake of the supercharger is made from the oil pan, so that the cooling water entering the supercharger does not flow through the cylinder block for cooling and heat absorption. The temperature of the cooling water is lower, thereby improving the cooling effect of the supercharger.

[0006] In some embodiments, the engine includes a water inlet pipe, and the water inlet pipe includes a water inlet interface and a water outlet interface. The water inlet interface is connected to the second water outlet, and the water outlet interface is connected to the supercharger.

[0007] In this way, by providing a water inlet pipe, the supercharger is connected to the second water outlet of the oil pan, so that the cooling water that has not been cooled can enter the supercharger for heat dissipation, thereby improving the cooling effect of the supercharger.

[0008] In some embodiments, the main body includes a side wall, and the water intake channel is arranged on the side wall, and / or the water intake channel is integrally formed with the main body.

[0009] By placing the water intake channel on the sidewall of the oil pan, cooling water for the supercharger can enter the supercharger before entering the cylinder block, improving supercharger cooling. The water intake channel is integrally formed with the main body, reducing the space it occupies and contributing to vehicle miniaturization.

[0010] In some embodiments, the cylinder body includes a first cylinder body and a second cylinder body, the first water outlet includes a first cylinder body water outlet and a second cylinder body water outlet, the second water inlet includes a first cylinder body water inlet and a second cylinder body water inlet, the first cylinder body water outlet is connected to the first cylinder body water inlet, and the second cylinder body water outlet is connected to the second cylinder body water inlet.

[0011] In this way, by connecting the cylinder block to the water intake passage, cooling water can enter the cylinder block, thereby dissipating heat from the cylinder block.

[0012] In some embodiments, the diameter of the first cylinder water outlet is smaller than the diameter of the second cylinder water outlet, so that the cooling water reaches the first cylinder water inlet and the second cylinder water inlet at the same flow rate.

[0013] In this way, since the second cylinder water outlet is farther from the first water inlet than the first cylinder water outlet, by setting the diameter of the first cylinder water outlet to be smaller than the diameter of the second water outlet, the flow rate of cooling water entering the first cylinder from the first cylinder water outlet is less, and the flow rate of cooling water entering the second cylinder from the second cylinder water outlet is more, so that the flow rate of cooling water reaching the first cylinder water inlet and the second cylinder water inlet can be the same within the same time, so that the first cylinder and the second cylinder are cooled evenly.

[0014] In some embodiments, the diameter of the first cylinder water outlet is greater than or equal to 17.8 mm and less than or equal to 18.2 mm, and the diameter of the second cylinder water outlet is greater than or equal to 22.8 mm and less than or equal to 23.2 mm.

[0015] In this way, by setting the diameter of the first cylinder water outlet to 17.8 mm to 18.2 mm and the diameter of the second cylinder water outlet to 22.8 mm to 23.2 mm, it can be ensured that the cooling water reaches the first cylinder water inlet and the second cylinder water inlet at the same flow rate within the same time, so that the first cylinder and the second cylinder are cooled evenly.

[0016] In some embodiments, the water intake channel includes a first channel and a second channel, one end of the first channel is connected to the first water inlet and the first cylinder water outlet, the other end of the first channel is connected to the second channel near the second water outlet, one end of the second channel is connected to the second cylinder water outlet, the other end of the second channel is connected to the second water outlet, and the length direction of the first channel is perpendicular to the length direction of the second channel.

[0017] Thus, by providing the first and second flow channels, cooling water can flow into the first and second cylinders, respectively. Furthermore, by aligning the length of the first flow channel with the length of the second flow channel, processing is facilitated, and the structure of the oil pan can be adapted, thereby reducing pressure loss of cooling water in the water intake channel.

[0018] In some embodiments, the cooling water reaches the first cylinder water inlet and the second cylinder water inlet at the same flow rate.

[0019] In this way, by setting the length of the first flow channel to be greater than the length of the second flow channel, the shape of the oil pan can be adapted, and at the same time, the time it takes for the cooling water to reach the water outlet of the second cylinder is longer than the time it takes for the cooling water to reach the water outlet of the first cylinder. Therefore, only the diameters of the water outlet of the first cylinder and the water outlet of the second cylinder need to be adjusted to control the water flow into the first cylinder and the second cylinder, so that the cooling of the first cylinder and the second cylinder is balanced.

[0020] In some embodiments, the length of the first flow channel is greater than that of the second flow channel, and the diameter of the first flow channel gradually decreases along the length direction toward the second flow channel.

[0021] In this way, by making the length of the first flow channel greater than that of the second flow channel, and by gradually decreasing the diameter of the first flow channel along the length direction toward the second flow channel, the pressure of the cooling water in the first flow channel can be reduced, while the pressure in the second flow channel can be increased. This ensures that the cooling water reaches the first and second cylinder water inlets at the same flow rate within the same time.

[0022] In certain embodiments, the diameter of the first flow channel is greater than or equal to 20.3 mm and less than or equal to 33 mm, the length of the first flow channel is greater than or equal to 287.3 mm and less than or equal to 287.7 mm, the diameter of the second flow channel is greater than or equal to 21.8 mm and less than or equal to 22.2 mm, and the length of the second flow channel is greater than or equal to 105 mm and less than or equal to 105.5 mm.

[0023] Thus, by setting the diameter of the first flow channel to 20.3-33 mm and the diameter of the second flow channel to 21.8 mm to 22.2 mm, the cooling water flow rate can be controlled. By setting the length of the first flow channel to 287.3 mm to 287.7 mm and the length of the second flow channel to 105 mm to 105.5 mm, the cooling water can be allowed to take longer to reach the water outlet of the second cylinder than to reach the water outlet of the first cylinder. Thus, by simply adjusting the diameters of the first and second cylinder water outlets, the water flow rates into the first and second cylinders can be controlled, ensuring balanced cooling of the first and second cylinders.

[0024] In some embodiments, the engine includes a cylinder water jacket, the cylinder water jacket includes a first cylinder water jacket and a second cylinder water jacket, the first cylinder water jacket is mounted on the first cylinder, the second cylinder water jacket is mounted on the second cylinder, the first cylinder water inlet is connected to the first cylinder water jacket, and the second cylinder water inlet is connected to the second cylinder water jacket.

[0025] In this way, by connecting the first cylinder water inlet and the second cylinder water inlet to the cylinder water jacket, the cooling water after dissipating heat through the first cylinder and the second cylinder can enter the cylinder water jacket, so that the cylinder water jacket further dissipates heat for the first cylinder and the second cylinder.

[0044] See also Figures 1 to 4 An engine 10 according to an embodiment of the present application includes a supercharger 11, an oil pan 12, and a cylinder block 14. The oil pan 12 includes a main body 121, which is provided with a water intake passage 13. The water intake passage 13 includes a first water inlet 131, a first water outlet 132, and a second water outlet 133. The first water inlet 131 is adapted to communicate with a water pump 15. The cylinder block 14 includes a second water inlet 141, which is in communication with the first water outlet 132. The second water outlet 133 is in communication with the supercharger 11.

[0045] In this way, by providing the water intake channel 13 on the oil pan 12, the water of the supercharger 11 is taken from the oil pan 12, so that the cooling water entering the supercharger 11 does not flow through the cylinder block 14 for cooling and heat absorption. The temperature of the cooling water is lower, thereby improving the cooling effect of the supercharger 11.

[0046] The engine 10 can serve as a power source for the vehicle 100, converting the chemical energy of the fuel into mechanical energy to drive the vehicle. The engine 10 of the vehicle 100 can include a horizontally opposed engine, an inline engine, or a V-type engine.

[0047] Specifically, the engine 10 includes a supercharger 11, an oil pan 12, and a cylinder block 14. The supercharger 11 pre-compresses the air entering the cylinder block 14, increasing its density and thereby increasing the amount of air entering the cylinder block 14. During the combustion process, the engine 10 can inject more fuel into the cylinder block 14, where it mixes with the air, resulting in more complete combustion. Therefore, the supercharger 11 can significantly increase the power output of the engine 10. However, since the supercharger 11 generates a large amount of heat during operation, cooling water is required to cool the supercharger 11.

[0048] The oil pan 12 is located at the bottom of the engine 10 and is connected to the cylinder block 14 to seal the cylinder block 14. This prevents external impurities such as dust and moisture from entering the cylinder block 14, thereby maintaining the cleanliness and normal operation of the engine 10. The oil pan 12 collects and stores lubricating oil that flows back from the engine 10, ensuring that the engine 10 is fully lubricated when needed. The oil pan 12 includes a main body 121, which defines a chamber for containing lubricating oil. A water intake channel 13 is provided on the main body 121 to allow cooling water to flow through the oil pan 12. The water intake channel 13 includes a first water inlet 131, which is connected to a water pump 15 located on the engine 10 via a pipe. The water pump 15 then pumps cooling water into the pipe, where it then flows through the first water inlet 131 and into the water intake channel 13. The water inlet channel 13 further includes a first water outlet 132 and a second water outlet 133, which can guide cooling water out of the water inlet channel 13. For example, the second water outlet 133 can be connected to the supercharger 11, so that the cooling water in the water inlet channel 13 can enter the supercharger 11 through the second water outlet 133 to absorb heat and help cool the supercharger 11.

[0049] The cylinder block 14 is the main body 121 of the engine 10 and provides a stable support structure for the engine 10. For example, the cylinder block 14 provides a mounting base for the various mechanisms and systems of the engine 10. The main components and accessories of the engine 10 are mounted inside and outside the cylinder block 14, allowing the cylinder block 14 to withstand various loads. A second water inlet 141 is provided on the contact surface of the cylinder block 14 near the oil pan 12. This second water inlet 141 is connected to the first water outlet 132. This allows cooling water in the water intake channel 13 to flow from the first water outlet 132 through the second water inlet 141 into the cylinder block 14, where it absorbs heat and helps cool the cylinder block 14.

[0050] See also Figure 4 In some embodiments, the engine 10 includes a water inlet pipe 16 , which includes a water inlet interface 161 and a water outlet interface 162 . The water inlet interface 161 is connected to the second water outlet 133 , and the water outlet interface 162 is connected to the supercharger 11 .

[0051] In this way, by providing the water inlet pipe 16 , the supercharger 11 is connected to the second water outlet 133 of the oil pan 12 , so that the cooling water that has not been cooled can enter the supercharger 11 for heat dissipation, thereby improving the cooling effect of the supercharger 11 .

[0052] Specifically, the engine 10 includes a water inlet pipe 16, which can be a water pipe or a pipeline opened on the engine 10. The water inlet pipe 16 includes a water inlet interface 161 and a water outlet interface 162. The size and shape of the water inlet interface 161 are compatible with the shape and size of the second water outlet 133, so that the water inlet interface 161 can communicate with the second water outlet 133, and the cooling water in the water intake channel 13 can enter the water inlet pipe 16 from the second water outlet 133 through the water inlet interface 161.

[0053] The size and shape of the water outlet interface 162 can be adapted to the shape and size of the supercharger 11, so that the water outlet interface 162 can be connected to the supercharger 11, and then the cooling water in the water intake pipe can enter the supercharger 11 from the water outlet interface 162 to absorb heat and help cool the supercharger 11.

[0054] See also Figure 5 and Figure 6 In some embodiments, the main body 121 includes a side wall 1211 , the water intake channel 13 is disposed on the side wall 1211 , and / or the water intake channel 13 is integrally formed with the main body 121 .

[0055] Thus, by disposing the water intake channel 13 on the side wall 1211 of the oil pan 12, cooling water for dissipating heat from the supercharger 11 can enter the supercharger 11 before entering the cylinder block 14, thereby improving the cooling effect of the supercharger 11. The water intake channel 13 is integrally formed with the main body 121, which can reduce the space occupied by the water intake channel 13 and facilitate the miniaturization of the vehicle 100.

[0056] Specifically, the main body 121 of the supercharger 11 includes a sidewall 1211, which can be used to connect to the cylinder block 14. The water intake channel 13 can be provided on the sidewall 1211. For example, when the water intake channel 13 is a pipe, it can be fixed to the inner sidewall 1211 or the outer sidewall 1211 of the main body 121 by welding or bolting.

[0057] The water intake channel 13 can be made with the main body 121 using an integrated manufacturing process. For example, the material of the main body 121 can be aluminum alloy, cast iron, alloy steel, or low-carbon steel. The molten metal of the main body 121 is injected into the mold under high pressure. After the molten metal cools, the main body 121 is formed. After the mold is demolded, the channel remaining inside the main body 121 can form the water intake channel 13, and the demolding opening can form the first water inlet 131, the second water inlet 141, the first water outlet 132, and the second water outlet 133. In this way, all the exit openings can be utilized, and there is no need to seal them with bolts, which reduces the risk of leakage due to poor sealing, while saving accessories and reducing costs.

[0058] See also Figure 7 In some embodiments, the cylinder body 14 includes a first cylinder body 142 and a second cylinder body 143, the first water outlet 132 includes a first cylinder body water outlet 1321 and a second cylinder body water outlet 1322, the second water inlet 141 includes a first cylinder body water inlet 1411 and a second cylinder body water inlet 1412, the first cylinder body water outlet 1321 is connected to the first cylinder body water inlet 1411, and the second cylinder body water outlet 1322 is connected to the second cylinder body water inlet 1412.

[0059] In this manner, by connecting the cylinder block 14 to the water intake passage 13 , cooling water can flow into the cylinder block 14 , thereby dissipating heat from the cylinder block 14 .

[0060] Specifically, engine 10 may be a horizontally opposed engine. The cylinder block 14 of the horizontally opposed engine includes a first cylinder block 142 and a second cylinder block 143. The first cylinder block 142 and the second cylinder block 143 each contain cylinders. These two cylinders convert the energy generated by fuel combustion into mechanical energy through the reciprocating motion of pistons, thereby providing power to vehicle 100. The cylinders in the two cylinder blocks are arranged in a horizontally opposed manner, allowing the pistons to reciprocate horizontally, which helps achieve balanced and stable power output. The first cylinder block 142 and the second cylinder block 143 can be connected to the oil pan 12 and sealed therewith.

[0061] The second water inlet 141 includes a first cylinder water inlet 1411 and a second cylinder water inlet 1412. The first cylinder water inlet 1411 is communicable with the first cylinder water outlet 1321, allowing cooling water in the water intake channel 13 to flow from the first cylinder water outlet 1321 through the second cylinder water inlet 1412 into the first cylinder 142, where it absorbs heat and helps cool the first cylinder 142. The second cylinder water outlet 1322 is communicable with the second cylinder water inlet 1412, allowing cooling water in the water intake channel 13 to flow from the second cylinder water outlet 1322 through the second cylinder water inlet 1412 into the second cylinder 143, where it absorbs heat and helps cool the second cylinder 143.

[0062] See also Figure 6 In some embodiments, the diameter of the first cylinder water outlet 1321 is smaller than the diameter of the second cylinder water outlet 1322 so that the cooling water reaches the first cylinder water inlet 1411 and the second cylinder water inlet 1412 at the same flow rate.

[0063] In this way, since the second cylinder water outlet 1322 is farther from the first water inlet 131 than the first cylinder water outlet 1321, by setting the diameter of the first cylinder water outlet 1321 to be smaller than the diameter of the second water outlet 133, the flow rate of cooling water entering the first cylinder 142 from the first cylinder water outlet 1321 is small, and the flow rate of cooling water entering the second cylinder 143 from the second cylinder water outlet 1322 is large, so that the flow rate of cooling water reaching the first cylinder water inlet 1411 and the second cylinder water inlet 1412 can be the same within the same time, so that the first cylinder 142 and the second cylinder 143 are cooled evenly.

[0064] Specifically, in order to avoid uneven distribution of the cooling water flow entering the first cylinder 142 and the second cylinder 143, reduce the temperature difference between the first cylinder 142 and the second cylinder 143, and improve the cooling effect of the cylinder body 14, it is necessary to make the diameter of the first cylinder water outlet 1321 smaller than the diameter of the second cylinder water outlet 1322.

[0065] It should be noted that since the first cylinder water outlet 1321 is close to the first water inlet 131, the cooling water will reach the first cylinder water outlet 1321 first, but reducing the diameter of the first cylinder water outlet 1321 can slow down the flow of cooling water reaching the first cylinder water outlet 1321; and the second cylinder water outlet 1322 is farther away from the first water inlet 131. When the cooling water flows into the second cylinder water outlet 1322, due to the larger diameter of the second cylinder water outlet 1322, the flow of cooling water that can pass through is larger, thereby ensuring that the water flow of cooling water reaching the first cylinder water inlet 1411 and the second cylinder water inlet 1412 is the same within the same time.

[0066] In some embodiments, the diameter of the first cylinder water outlet 1321 is 17.8 mm to 18.2 mm. For example, the diameter of the first cylinder water outlet 1321 can be 17.8 mm, 17.9 mm, 18 mm, 18.1 mm, 18.2 mm, or other values between 17.8 mm and 18.2 mm.

[0067] In some embodiments, the diameter of the second cylinder water outlet 1322 is 22.8 mm to 23.2 mm. For example, the diameter of the second cylinder water outlet 1322 can be 22.8 mm, 22.9 mm, 23 mm, 23.1 mm, 23.2 mm, or other values between 22.8 mm and 23.2 mm. Thus, by setting the diameter of the first cylinder water outlet 1321 to 17.8-18.2 mm and the diameter of the second water outlet 133 to 22.8-23.2 mm, it is possible to ensure that the same amount of cooling water reaches the first cylinder water inlet 1411 and the second cylinder water inlet 1412 within the same time period, thereby achieving balanced cooling of the first cylinder 142 and the second cylinder 143.

[0068] See also Figure 6 and Figure 7 In some embodiments, the water intake channel 13 includes a first channel 134 and a second channel 135, one end of the first channel 134 is connected to the first water inlet 131 and the first cylinder water outlet 1321, the other end of the first channel 134 is connected to the second channel 135 near the second water outlet 133, one end of the second channel 135 is connected to the second cylinder water outlet 1322, and the other end of the second channel 135 is connected to the second water outlet 133, and the length direction of the first channel 134 is perpendicular to the length direction of the second channel 135.

[0069] Thus, by providing the first flow channel 134 and the second flow channel 135, cooling water can flow into the first cylinder 142 and the second cylinder 143, respectively. Furthermore, by aligning the length of the first flow channel 134 with the length of the second flow channel 135 at right angles, processing is facilitated, and the structure of the oil pan 12 can be adapted, thereby reducing the pressure loss of the cooling water in the water intake channel 13.

[0070] Specifically, the water intake channel 13 also includes a first channel 134 and a second channel 135. One end of the first channel 134 can communicate with the first water inlet 131 and the first cylinder water outlet 1321, so that cooling water pumped by the water pump 15 can enter the first channel 134 through the first water inlet 131, and the cooling water in the first channel 134 can flow out through the first cylinder water outlet 1321. The other end of the first channel 134 can communicate with the second channel 135, and the connection point is on the side wall 1211 of the second channel 135 near the second water outlet 133, so that the cooling water in the first channel 134 can flow into the second channel 135.

[0071] One end of the second flow channel 135 can be communicated with the second cylinder water outlet 1322, so that the cooling water in the second flow channel 135 can flow out from the second cylinder water outlet 1322. The other end of the second flow channel 135 can be communicated with the second water outlet 133, so that the cooling water in the second flow channel 135 can flow out from the second water outlet 133.

[0072] The length direction of the first flow channel 134 is perpendicular to the length direction of the second flow channel 135 , that is, the flow direction of the cooling water in the first flow channel 134 is perpendicular to the flow direction of the cooling water in the second flow channel 135 , thereby being able to adapt to the shape of the main body 121 of the oil pan 12 .

[0073] The length of first flow channel 134 is greater than that of second flow channel 135, and the diameter of first flow channel 134 gradually decreases along the length direction toward second flow channel 135. Thus, by making the length of first flow channel 134 greater than that of second flow channel 135, and by gradually decreasing the diameter of first flow channel 134 along the length direction toward second flow channel 135, the pressure of the cooling water in first flow channel 134 can be reduced, while the pressure in second flow channel 135 can be increased. This ensures that the same amount of cooling water reaches first cylinder water inlet 1411 and second cylinder water inlet 1412 within the same time period.

[0074] In some embodiments, the diameter of the first flow channel 134 is 20.3 mm to 33 mm. For example, the diameter of the first flow channel 134 can be 20.3 mm, 23.3 mm, 26.3 mm, 29.3 mm, 33 mm, or other values between 20.3 mm and 33 mm.

[0075] The length of the first flow channel 134 is 287.3 mm to 287.7 mm. For example, the length of the first flow channel 134 may be 287.3 mm, 287.4 mm, 287.5 mm, 287.6 mm, 287.7 mm, or other values between 287.3 mm and 287.7 mm.

[0076] The diameter of the second flow channel 135 is 21.8 mm to 22.2 mm. For example, the diameter of the second flow channel 135 is 21.8 mm, 21.9 mm, 22 mm, 22.1 mm, 22.2 mm, or other values between 21.8 mm and 22.2 mm.

[0077] The length of the second flow channel 135 is 105 mm to 105.5 mm. For example, the length of the second flow channel 135 is 105 mm, 105.1 mm, 105.2 mm, 105.3 mm, 105.4 mm, 105.5 mm, or other values between 105 mm and 105.5 mm.

[0078] Thus, by setting the diameter of first flow channel 134 to 20.3 mm to 33 mm and the diameter of second flow channel 135 to 21.8 mm to 22.2 mm, the cooling water flow rate can be controlled. By setting the length of first flow channel 134 to 287.3 mm to 287.7 mm and the length of second flow channel 135 to 105 mm to 105.5 mm, the cooling water can be made to take longer to reach second cylinder water outlet 1322 than to reach first cylinder water outlet 1321. Thus, by simply adjusting the diameters of first cylinder water outlet 1321 and second cylinder water outlet 1322, the water flow rates into first cylinder 142 and second cylinder 143 can be controlled, ensuring balanced cooling of first cylinder 142 and second cylinder 143.

[0079] See also Figure 8 In some embodiments, the engine 10 includes a cylinder water jacket 17, which includes a first cylinder water jacket 171 and a second cylinder water jacket 172. The first cylinder water jacket 171 is mounted on the first cylinder 142, and the second cylinder water jacket 172 is mounted on the second cylinder 143. The first cylinder water inlet 1411 is connected to the first cylinder water jacket 171, and the second cylinder water inlet 1412 is connected to the second cylinder water jacket 172.

[0080] In this way, by connecting the first cylinder water inlet 1411 and the second cylinder water inlet 1412 to the cylinder water jacket 17, the cooling water after dissipating heat through the first cylinder 142 and the second cylinder 143 can enter the cylinder water jacket 17, so that the cylinder water jacket 17 further dissipates heat for the first cylinder 142 and the second cylinder 143.

[0081] Specifically, the engine 10 further includes a cylinder water jacket 17, which includes a first cylinder water jacket 171 and a second cylinder water jacket 172. The cylinder water jacket 17 can surround the sidewall of the cylinder block 14. For example, the first cylinder water jacket 171 surrounds the sidewall of the first cylinder block 141, and the second cylinder water jacket 172 surrounds the sidewall of the second cylinder block 142. Furthermore, a first cylinder water inlet 1411 on the cylinder block 14 can communicate with the first cylinder water jacket 171, and a second cylinder water inlet 1412 can communicate with the second cylinder water jacket 172. This allows cooling water in the water intake channel 13 to pass through the first cylinder water inlet 1411, absorb heat, and then enter the first cylinder water jacket 171. Furthermore, cooling water in the water intake channel 13 can pass through the second cylinder water inlet 1412, absorb heat, and then enter the second cylinder water jacket 172. Thus, the cylinder water jacket 17 transfers the high-temperature heat energy generated by the combustion chamber and the inner wall of the cylinder of the engine 10 to the cooling water by heat conduction. The cooling water circulates in the cylinder water jacket 17, absorbs and takes away the heat, and then circulates to the radiator through the water pump 15 for heat dissipation. The radiator uses the flow of external air to further reduce the temperature of the coolant. Thereafter, the cooled cooling water circulates back to the water jacket of the engine 10 again to continue absorbing heat.
