Description
Technical Field
The utility model belongs to the technical field of the piston cooling, especially, relate to a nozzle.
Background
In order to meet the restriction of the oil consumption regulation, most internal combustion engine manufacturers adopt technologies such as direct injection in cylinders and turbocharging, and meanwhile, the overall quality or size of the engine can be reduced through the improvement of materials and structures, and the oil consumption of the whole automobile can also be reduced.
In order to ensure the working reliability of the piston and avoid the excessive thermal expansion deformation of the piston, the risk of cylinder pulling between the piston and the cylinder wall is reduced, and the heat absorbed by the piston from a combustion system needs to be taken away in time. For the naturally aspirated internal combustion engine, heat conduction is generally carried out through piston rings and piston skirt portions, and splash lubrication generated by the movement of a connecting rod is used for cooling; however, for supercharged and direct injection engines, the cooling method of the naturally aspirated engine cannot meet the cooling of the piston under higher thermal load, according to the data, the limit lubrication temperature of the lubricating oil is generally not more than 140 ℃, when the oil is injected by a non-cooling nozzle, the temperature of the top of the piston is close to the exhaust temperature of the combustion chamber, and due to the influence of the supercharger, the exhaust temperature of the combustion chamber reaches nearly 500 ℃ at 1000rpm, while the temperature of the top of the piston is controlled below 300 +/-50 ℃, so that the forced cooling measure of the piston must be adopted. Referring to the cooling mode of the combustion chamber, the forced cooling of the piston can be realized by adopting engine oil, and the adding of the piston cooling nozzle is the most widely applied one of the forced cooling methods of the piston.
The opening, closing and flow control of the present piston cooling nozzle is directly related to the pressure of the main oil gallery of the internal combustion engine. Adopt the spring pretightning force to make the oil feed port of steel ball closed nozzle cavity promptly, when the machine oil pressure in the main oil duct is greater than the spring pretightning force, the spring is compressed by the steel ball, and machine oil flows into the nozzle cavity, sprays the piston inside through piston cooling nozzle, because the temperature of piston is higher than the machine oil temperature far away to the effect of cooling the piston has been played. However, when the engine is just started, the temperature of the piston is low, and if the piston cooling nozzle works at the moment, the cold start of the engine and the establishment of an initial lubricating system are not facilitated; when the piston is in a working condition range of high load and easy knocking, the working temperature is high, forced cooling is needed, the flow of the cooling nozzle at the moment is only influenced by the pressure of the main oil duct, the cooling flow of the piston under the working condition cannot be increased, the piston cannot be cooled well, and finally the fuel consumption of an engine is increased.
