[0053] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. It should be noted that the diagrams provided in the embodiments only schematically illustrate the basic concepts of the present application, and therefore only show the components related to the present application in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The shape, number and proportion of each component in actual implementation can be arbitrarily changed, and the component layout form can also be more complex.

[0054] An engine lubrication system, referring to Figure 1 and Figure 4 , has engine oil therein, and the lubrication system changes the temperature of the engine and plays a lubricating effect through circulation of the engine oil. The lubrication system comprises an oil pan 1, a magnetic adsorption accessory 2, a cylinder water jacket 3 and a cooling circuit 4. The oil pan 1 is used to contain the engine oil. The magnetic adsorption accessory 2 is located in the oil pan 1, and is used to adsorb magnetic impurities in the oil pan 1. The cylinder water jacket 3 is connected with the oil pan 1, and the cylinder water jacket 3 is provided with a cooling oil passage and flows through the engine oil. The cooling circuit 4 is wrapped around the cylinder water jacket 3, and the cooling circuit 4 is filled with cooling liquid.

[0055] The beneficial effects of the embodiment are that the metal impurities generated in the oil passage circulation process are adsorbed by the magnetic adsorption accessory 2 provided in the oil pan 1, thereby playing a filtering effect on the engine oil, effectively reducing the amount of impurities in the engine oil, and playing the effect of an engine oil filter. Since the cylinder water jacket 3 is a node through which the engine oil circulates in the lubrication system, the cooling circuit 4 is provided outside the cylinder water jacket 3, and the engine oil is cooled by filling the cooling oil passage with cooling liquid, thereby effectively reducing the temperature of the engine oil and avoiding damage to the engine caused by excessively high engine oil temperature. In summary, the magnetic adsorption accessory 2 and the cooling circuit 4 are provided in the lubrication system, thereby avoiding the need to provide an engine oil cooler and an engine oil filter, thereby reducing the complexity and cost of the system.

[0056] In some embodiments of the present application, referring to Figure 1 and Figure 3 , the magnetic adsorption accessory 2 is in a mesh shape. In this way, the mesh-shaped magnetic adsorption accessory 2 facilitates the adsorption of magnetic impurities and the passage of engine oil, without hindering the flow of engine oil.

[0057] In other embodiments, referring to Figure 1 and Figure 3 , the mesh-shaped filter structure of the magnetic adsorption accessory 2 can also block non-magnetic impurities such as large-particle impurities in the engine oil.

[0058] In some embodiments of the present application, referring to Figure 1 and Figure 3 , the oil returns to the oil pan 1 through the top of the oil pan 1, and the magnetic adsorption member 2 divides the oil pan 1 into a first oil containing part 1-1 and a second oil containing part 1-2 in a longitudinal or oblique direction. In this way, since the oil returns to the oil pan 1 through the entire top of the oil pan 1, the top of the oil pan 1 is divided into regions and the magnetic adsorption member 2 is arranged, which facilitates the adsorption of impurities in more returned oil, that is, more returned oil is brought into contact with the magnetic adsorption member 2 as much as possible.

[0059] The lubrication system further comprises an electronic oil pump 5 for pumping oil in the oil pan 1 and a filter 6, both of which are arranged in the first oil containing part 1-1; most or all of the area of the top of the oil pan 1 is located in or above the region of the second oil containing part 1-2. In this way, by dividing the oil pan 1 into two parts and locating most or all of the area of the top of the oil pan 1 in or above the region of the second oil containing part 1-2, most or all of the returned oil will first enter the second oil containing part 1-2, and then enter the first oil containing part 1-1 after being adsorbed by the magnetic adsorption member 2, thereby improving the adsorption effect of the returned oil and reducing the content of metal impurities in the returned oil after circulation.

[0060] In other embodiments, referring to Figure 1 and Figure 3 , the magnetic adsorption member 2 can be arranged vertically; or the magnetic adsorption member 2 can be arranged obliquely, which can better encompass the top region of the oil pan 1. If the second oil containing part 1-2 encompasses the entire top region of the oil pan 1, all returned oil will pass through the second oil containing part 1-2, the magnetic adsorption member 2 and the first oil containing part 1-1 in turn, thereby ensuring the adsorption effect of the magnetic adsorption member 2 on the circulated oil. It should be emphasized that whether the magnetic adsorption member 2 is arranged vertically or obliquely, most or all of the area of the top of the oil pan 1 should be located in or above the region of the second oil containing part 1-2, thereby ensuring the adsorption effect of the magnetic adsorption member 2 on the oil.

[0061] In other embodiments, the magnetic adsorption member 2 is not necessarily arranged vertically or obliquely, but can be arranged horizontally. If the magnetic adsorption member 2 encompasses the entire top of the oil pan 1 when arranged horizontally, all returned oil will pass through the second oil containing part 1-2, the magnetic adsorption member 2 and the first oil containing part 1-1 in turn before being circulated again by the electronic oil pump 5, thereby ensuring the adsorption effect.

[0062] In some embodiments, referring to Figure 1 and Figure 3 a PWM controller is further provided for controlling the working state of the electronic oil pump 5, and the circular workpiece connected with the electronic oil pump 5 and the filter 6 in the application can be the PWM controller.

[0063] In some embodiments of the application, referring to Figure 3 the lubricating system further comprises a baffle 7, which is obliquely arranged in the oil pan 1, the upper end of the baffle 7 extends above the first oil containing part 1-1, and the lower end of the baffle 7 extends above the magnetic attraction accessory 2 or abuts against the top of the magnetic attraction accessory 2, the baffle 7 is used for guiding the oil back into the oil pan 1 into the second oil containing part 1-2. In this way, since the oil participating in the circulation flows through multiple workpieces, metal impurities are easily generated in the process, which are brought back into the oil pan 1 by the backflow of the oil. By providing the baffle 7, the application ensures that all the oil backflowing from the top of the oil pan 1 first enters the second oil containing part 1-2, then successively passes through the magnetic attraction accessory 2 and the first oil containing part 1-1, and then is pumped out again by the electronic oil pump 5 and enters the next cycle, effectively adsorbing impurities in the oil, reducing metal impurities or large particle impurities, thereby ensuring the quality of the oil entering the subsequent circulation.

[0064] In some embodiments, the magnetic attraction accessory 2 can be a simple mesh structure or a multi-layer adsorption structure with gaps.

[0065] The remaining edges of the magnetic attraction accessory 2 except the top abut against the inner wall of the oil pan 1. In order to make the oil flowing back along the top of the oil pan 1 into the oil pan 1 first enter the second oil containing part 1-2, and then pass through the magnetic attraction accessory 2 and enter the first oil containing part 1-1. In this way, all the backflowing oil can first pass through the magnetic attraction accessory 2 for impurity removal before continuing to participate in the lubrication cycle.

[0066] In some embodiments of the application, referring to Figure 1 and Figure 2 the lubricating system further comprises a sediment chamber 8, which is located directly below the magnetic attraction accessory 2, and the sediment chamber 8 is in communication with the oil pan 1 and is used for containing impurities. In this way, by providing the sediment chamber 8, the entry of particulate impurities and the accumulation of impurities are facilitated. Since the magnetic attraction accessory 2 not only adsorbs impurities but also blocks large particle impurities, the sediment chamber 8 is arranged below the magnetic attraction accessory 2 to facilitate the sediment chamber 8 to receive the impurities falling from the magnetic attraction accessory 2.

[0067] In some other embodiments, the magnetic member 2 is an electromagnetic structure, i.e., the magnetic member 2 has magnetism when powered and loses magnetism when powered off. According to this characteristic of the magnetic member 2, the magnetic member 2 can be powered off to make the particle impurities adsorbed on the magnetic member 2 fall off and fall into the sediment chamber 8, thereby accumulating the particle impurities and avoiding the problem of reducing the adsorption magnetic force of the periphery of the magnetic member 2 due to too many metal impurities on the magnetic member 2.

[0068] In some other embodiments, referring to Figure 1 and Figure 2 , the sediment chamber 8 protrudes outward along the bottom of the oil pan 1, so that the periphery of the sediment chamber 8 blocks the impurities and avoids the impurities from entering the first oil accommodating portion 1-1 again along the flow direction of the oil.

[0069] In some embodiments of the present application, the bottom of the magnetic member 2 extends to the top of the sediment chamber 8, and the magnetic member 2 spans the middle of the sediment chamber 8, so that the impurities on both sides of the magnetic member 2 can fall into the sediment chamber. In this way, since the two sides of the magnetic member 2 are located in the first oil accommodating portion 1-1 and the second oil accommodating portion 1-2, respectively, by limiting the spanning range of the sediment chamber 8, the lower part of both sides of the magnetic member 2 can correspond to the sediment chamber 8, so that the sediment chamber 8 can conveniently receive the magnetic impurities falling from both sides of the magnetic member 2. Specifically, the length and width of the sediment chamber 8 are both greater than those of the magnetic member 2, so as to effectively receive the impurities falling from the magnetic member 2.

[0070] In some embodiments of the present application, referring to Figure 4 and Figure 5 , the cooling circuit 4 includes a cooling portion 4-1, a water inlet nozzle 4-2, and a water outlet nozzle 4-3. The cooling portion 4-1 is in a cylindrical shape and surrounds the arc surface of the cylinder water jacket 3. The water inlet nozzle 4-2 is connected to one end of the axial direction of the cooling portion 4-1, and the water outlet nozzle 4-3 is connected to the other end of the axial direction of the cooling portion 4-1. In this way, by arranging the water inlet nozzle 4-2 and the water outlet nozzle 4-3, the cooling liquid can flow in the cooling circuit 4, thereby enhancing the cooling effect of the oil in the cylinder water jacket 3, so that the oil flowing through the cylinder water jacket 3 can be quickly cooled. By surrounding the cooling portion 4-1 around the periphery of the cylinder water jacket 3, the arc surface of the cylinder water jacket 3 can be heat-exchanged, thereby increasing the heat exchange area of the cylinder water jacket 3 and effectively improving the heat exchange efficiency.

[0071] In some other embodiments, the commonly used cooling liquid is water.

[0072] In some embodiments of the present application, referring to Figure 5The cooling circuit 4 includes a first proportional three-way valve 4-4, which is located next to the water inlet 4-2. By setting the first proportional three-way valve 4-4, the flow rate of the coolant in the cooling circuit 4 can be adjusted, thereby changing the oil temperature and regulating it to a suitable value.

[0073] The lubrication system also includes a main oil passage 9, a turbocharger 10, and a sensor 11. The main oil passage 9 is located between the oil pan 1 and the cylinder block water jacket 3; the turbocharger 10 is connected to the main oil passage 9; the sensor 11 is located in the main oil passage 9 and is used to monitor the temperature and / or pressure of the engine oil. In this way, by setting the sensor 11 in the main oil passage 9, the parameters of the engine oil are fed back in a timely manner, and the flow rate of the coolant can be adjusted according to the feedback parameters.

[0074] In one embodiment, see Figure 5 The main oil passage 9 is equipped with both a temperature sensor 11 and a pressure sensor 11 to provide feedback on the temperature and pressure of the oil. The main oil passage 9 is also connected to a turbocharger 10.

[0075] In other embodiments, see Figure 5 The oil pump draws oil from the oil pan 1, pressurizes it, and delivers it to the main oil passage 9. The main oil passage 9, acting as the "main artery" of the lubrication system, runs along the engine block. Through a series of branch oil passages, it simultaneously delivers oil to various parts requiring lubrication and cooling, including the main bearings 9-1 and connecting rod bearings 9-2. The main bearings 9-1 support the crankshaft, and the connecting rod bearings 9-2 connect the connecting rods to the crankshaft. Both bearings experience immense pressure and friction during engine operation, generating significant heat. To ensure normal engine operation, both require sufficient oil for lubrication and cooling to reduce wear and control temperature. In this application, the main oil passage 9 is directly connected to five main bearings 9-1, designated C1, C2, C3, C4, and C5. Each of C2 to C5 is connected to a connecting rod bearing 9-2, which in turn is designated B1, B2, B3, and B4.

[0076] In some embodiments of this application, see Figure 5 The lubrication system also includes a second proportional three-way valve 12, a cylinder head exhaust-side lubrication passage 13, a cylinder head intake-side lubrication passage 14, and a piston cooling nozzle oil passage 15. The second proportional three-way valve 12 has a normally open first end and a second end, and a switchable third end. The first end is connected to the cylinder block water jacket 3; the second end is connected to both the cylinder head exhaust-side lubrication passage 13 and the cylinder head intake-side lubrication passage 14; and the piston cooling nozzle oil passage 15 is connected to the third end. Thus, by setting the second proportional three-way valve 12 to adjust the on / off state of the circuit connected to the third end, the piston cooling effect is achieved.

[0077] In some other embodiments, referring to Figure 5 “Always on” means a state of being always open, and “switchable” means that the switch can be selected to be open or closed according to the power of the engine, that is, whether to open the third end is selected by the working state of the engine.

[0078] In some other embodiments, referring to Figure 5 The cylinder head exhaust side lubricating oil passage 13 is connected with the exhaust side cam, hydraulic tappet and VVT, the cylinder head intake side lubricating oil passage 14 is connected with the intake side cam, hydraulic tappet, VVT and high-pressure fuel pump, the piston cooling nozzle oil passage 15 is connected with four piston cooling nozzles 15-1, the piston cooling nozzle 15-1 is used for cooling the piston body 15-2, and each piston cooling nozzle 15-1 is arranged in correspondence with one piston body 15-2. Wherein, VVT is a variable valve timing technology, which is an advanced technology for automobile engine, when applied to the cylinder head exhaust side, VVT can accurately control the opening and closing time of the exhaust valve according to different working conditions of the engine.
