Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engine oil devices, in particular to a longitudinally mounted oil nozzle for a pickup truck. Background Art
[0002] The oil nozzle under the piston of the engine cylinder is an important lubrication system component. Its main function is to spray oil on the piston and cylinder wall to achieve lubrication and cooling effects. During the operation of the engine, the friction between the piston and the cylinder wall will generate a lot of heat and wear. In order to protect the piston and cylinder wall, the oil nozzle will spray an appropriate amount of oil on the piston and cylinder wall to form an oil film to reduce friction and wear, and at the same time take away the heat to maintain the normal operation of the engine. The oil nozzle is usually located under the piston and sprays the oil through tiny spray holes to form a mist. The atomized oil can better cover the piston and cylinder wall to form a uniform oil film, thereby improving the lubrication effect and fuel economy.
[0003] During cold start, the engine temperature is low, the oil viscosity is high, and the fluidity is poor. At this time, the oil nozzle needs to provide a larger spraying area to fully lubricate the various parts of the engine and reduce friction and wear during startup. At the same time, a larger spraying area can better distribute the oil evenly on the cylinder wall and promote rapid preheating of the engine. Under high-temperature working conditions, the engine temperature rises, the oil viscosity decreases, and the fluidity increases. At this time, the oil nozzle needs to provide a smaller spraying area to reduce oil waste and pollution. At the same time, a smaller spraying area can better control the amount of oil sprayed, so that the oil can be sprayed more concentratedly on the parts that need lubrication, thereby improving the lubrication effect and fuel economy. Therefore, when the temperature inside the engine is different, the spraying area of the nozzle needs to be changed to achieve the best effect. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the deficiencies of the prior art, the utility model provides a longitudinally mounted oil nozzle for a pickup truck, which has the advantage of self-adjusting the oil spraying area and solves the problem of engine piston lubrication.
[0006] (II) Technical solution
[0007] In order to achieve the purpose of the above-mentioned self-adjusting oil spraying area, the utility model provides the following technical solutions: an oil nozzle for a longitudinally mounted pickup truck, comprising a cylinder nozzle and a cylinder where the engine piston is located, the cylinder nozzle being arranged under the cylinder through a fixed seat, the cylinder nozzle being able to spray the oil only onto the cylinder wall, a baffle cap being provided at the oil spraying point of the cylinder nozzle, when the internal temperature of the engine is low, the oil sprayed from the cylinder nozzle being able to pass through the baffle cap and being sprayed onto the inner wall of the cylinder body, when the temperature of the engine is high, the oil sprayed from the cylinder nozzle being blocked and unable to pass through the baffle cap and being able to be sprayed from the side between the cylinder nozzle and the baffle cap.
[0008] Preferably, the baffle cap is fixed to the cylinder nozzle via a solid ring and a bracket, and a gap is provided between the brackets. When the engine is at a high temperature, when the baffle cap blocks the engine oil, the engine oil can pass through the gap between the brackets and spray to the bottom of the cylinder.
[0009] Preferably, the solid ring and the cylinder nozzle are connected by threads, and the fixing seat is detachably connected in the cylinder. The detachable connection design makes the removal and installation of the nozzle and the fixing ring simple and convenient, and the damaged nozzle can be quickly replaced or repaired, reducing the maintenance time and cost. Since the working requirements and designs of different engines may be different, the detachable connection design can better meet the needs of different engines. By replacing the cylinder nozzles with different parameters, the lubrication requirements of the engine can be better met, the working efficiency and reliability of the engine can be improved, the production efficiency can be improved, and the production cost can be reduced. The detachable connection design is convenient for cleaning and inspection of the oil nozzle, and any problems can be discovered and handled in time to ensure the normal operation of the engine.
[0010] Preferably, the baffle cap is densely covered with pores, and a thermal expansion layer is provided in the middle of the baffle cap. When the thermal expansion layer expands due to heat, the pores are blocked. When the temperature is normal and the thermal expansion layer does not expand, the pores are not blocked, so that the engine oil sprayed from the cylinder nozzle can pass through the pores. The thermal expansion layer is specifically a composite material composed of ceramic materials (such as aluminum oxide, silicon nitride) and metal materials (such as copper, aluminum, steel, etc.), which has good thermal expansion properties and mechanical strength as well as high thermal stability and high temperature resistance.
[0011] Preferably, the pores are inclined outwardly, and the outer pores are inclined at a larger angle than the inner pores, so that when the engine oil is sprayed from the nozzle through the baffle cap, the engine oil passes through the pores and becomes mist. At the same time, the pores are inclined outwardly, and the engine oil diffuses in an arc along the path, providing a larger spraying area to fully lubricate various components of the engine and reduce friction and wear during startup.
[0012] (III) Beneficial effects
[0013] Compared with the prior art, the utility model provides a longitudinally mounted oil nozzle for a pickup truck, which has the following beneficial effects:
[0014] 1. The longitudinal pickup oil nozzle has a low temperature, high oil viscosity and poor fluidity when the engine is just started. A baffle cap is set at the nozzle outlet with dense pores on the baffle cap, and the pores are inclined to the outside. When the oil is sprayed out from the cylinder nozzle, the pores transform the whole into a divergent mist, providing a larger spraying area to fully lubricate the various parts of the engine and reduce friction and wear during startup. The larger spraying area can make the oil better cover the cylinder wall, crankshaft neck and other parts to form a thicker oil film, reduce direct contact between metal and metal, and thus reduce wear. At the same time, the larger spraying area can better distribute the oil evenly to various parts and promote rapid preheating of the engine, so that the engine can reach normal operating temperature faster and reduce poor lubrication and component damage caused by local overheating.
[0015] 2. The oil nozzle for the longitudinal pickup truck, when working at high temperature, the engine temperature rises, the oil viscosity decreases, and the fluidity increases. The high temperature causes the thermal expansion layer inside the baffle cap to expand, blocking the pores on the baffle cap. The blocked oil can only be sprayed onto the cylinder wall from the gap between the brackets. Because the cylinder nozzle is required to provide a smaller spraying area under high temperature conditions to reduce oil waste and pollution, a smaller spraying area can make the oil more concentratedly sprayed on parts that need lubrication, such as piston rings, crankshaft necks, etc., to form a more precise and effective lubrication, which can improve the lubrication effect and fuel economy, and reduce unnecessary oil consumption and emissions. At the same time, a smaller spraying area can also reduce the formation of carbon deposits and sludge caused by oil splashing, keep the inside of the engine clean, and at the same time, avoid a large amount of oil from forming a thicker oil film on the cylinder wall, which increases the resistance to the piston and causes problems such as engine de-cylindering.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-2 The oil nozzle for a longitudinal pickup truck includes a cylinder nozzle 1 and a cylinder 101 where the engine piston is located. The cylinder nozzle 1 is arranged below the cylinder 101 through a fixing seat 11. The cylinder nozzle 1 can spray the oil only on the wall of the cylinder 101. A baffle cap 14 is provided at the oil spraying position of the cylinder nozzle 1. When the internal temperature of the engine is low, the oil sprayed from the cylinder nozzle 1 can pass through the baffle cap 14 and spray onto the inner wall of the cylinder 101. When the engine temperature is high, the oil sprayed from the cylinder nozzle 1 is blocked and cannot pass through the baffle cap 14, and can only be sprayed from the side between the cylinder nozzle 1 and the baffle cap 14.
[0022] The stop cap 14 is fixed on the cylinder nozzle 1 through a solid ring 12 and a bracket 13 , and gaps are provided between the brackets 13 . When the engine is at high temperature, when the stop cap 14 blocks the engine oil, the engine oil can pass through the gaps between the brackets 13 and spray to the bottom of the cylinder 101 .
[0023] The solid ring 12 and the cylinder nozzle 1 are connected by threads, and the fixing seat 11 is detachably connected in the cylinder 101. The detachable connection design makes the removal and installation of the nozzle and the fixing ring 12 simple and convenient, and the damaged nozzle can be quickly replaced or repaired, reducing the maintenance time and cost. Since the working requirements and designs of different engines may be different, the detachable connection design can better meet the needs of different engines. By replacing the cylinder nozzle 1 with different parameters, the lubrication requirements of the engine can be better met, the working efficiency and reliability of the engine can be improved, the production efficiency can be improved, and the production cost can be reduced. The detachable connection design is convenient for cleaning and inspection of the oil nozzle, and any problems can be discovered and handled in time to ensure the normal operation of the engine.
[0024] See also Figure 3The baffle cap 14 is densely covered with pores 142, and a thermal expansion layer 141 is provided in the middle of the baffle cap 14. When the thermal expansion layer 141 expands due to heat, the pores 142 are blocked. When the temperature is normal and the thermal expansion layer 141 does not expand, the pores 142 are not blocked, so that the oil sprayed from the cylinder nozzle 1 can pass through the pores 142. The thermal expansion layer 141 is specifically a composite material composed of a ceramic material (such as alumina, silicon nitride) and a metal material (such as copper, aluminum, steel, etc.), which has good thermal expansion performance and mechanical strength, as well as high thermal stability and high temperature resistance.
[0025] Furthermore, the pores 142 are inclined outwardly, and the outer pores 142 are inclined at a larger angle than the inner pores, so that when the engine oil is sprayed from the nozzle through the baffle cap 14, the engine oil passes through the pores 142 and becomes mist. At the same time, the pores 142 are inclined outwardly, and the engine oil diffuses in an arc along the path, providing a larger spraying area to fully lubricate various components of the engine and reduce friction and wear during startup.
[0026] Working principle: a cylinder nozzle 1 is arranged below the engine cylinder 101, through which the engine oil can be sprayed on the cylinder 101 wall below the engine piston, which plays a role in lubrication and cooling. When the engine is just started, the temperature is low, the oil viscosity is large, and the fluidity is poor. By arranging a baffle cap 14 at the nozzle outlet, the baffle cap 14 is provided with dense pores 142, and the pores 142 are inclined to the outside. When the engine oil is sprayed out from the cylinder nozzle 1, the pores 142 make the whole body transform into a divergent mist, providing a larger spraying area to fully lubricate various parts of the engine and reduce friction and wear during startup. The larger spraying area can make the engine oil better cover the cylinder wall, crankshaft neck and other parts, forming a thicker oil film, reducing direct contact between metal and metal, thereby reducing wear. At the same time, the larger spraying area can better distribute the engine oil evenly in various parts, promote rapid preheating of the engine, so that the engine can reach the normal operating temperature faster and reduce the damage caused by local overheating. Poor lubrication and component damage caused by heat. Under high-temperature working conditions, the engine temperature rises, the viscosity of the engine oil decreases, and the fluidity increases. The high temperature causes the thermal expansion layer 141 inside the baffle cap 14 to expand due to the heat, and the pores 142 on the baffle cap 14 are blocked. The blocked engine oil can only be sprayed onto the wall of the cylinder body 101 from the gap between the brackets 13. Because the cylinder nozzle 1 needs to provide a smaller spraying area under high-temperature conditions to reduce the waste and pollution of the engine oil, a smaller spraying area can make the engine oil more concentratedly sprayed on the parts that need lubrication, such as piston rings, crankshaft necks, etc., to form a more precise and effective lubrication, which can improve the lubrication effect and fuel economy, and reduce unnecessary oil consumption and emissions. At the same time, a smaller spraying area can also reduce the formation of carbon deposits and sludge caused by oil splashing, keep the inside of the engine clean, and at the same time, avoid a large amount of oil from forming a thicker oil film on the wall of the cylinder body 101, which increases the resistance to the piston and causes the engine to de-cylinder.
