Abstract
The utility model discloses a cooler for an engine piston. The cooler comprises a pressure regulating valve, a main oil channel and piston cooling nozzles, and is characterized by also comprising an auxiliary oil channel, wherein the pressure regulating valve is arranged between the main oil channel and the auxiliary oil channel; one end of each piston cooling nozzle is communicated with the auxiliary oil channel; and the piston cooling nozzles can be a first piston cooling nozzle, a second piston cooling nozzle, a third piston cooling nozzle and a fourth piston cooling nozzle which are arranged in parallel at intervals and are communicated with the auxiliary oil channel at one end. Necessary lubricating oil can be supplied to a high-temperature and high-load piston running at a high speed for cooling, so that frictional loss of the piston can be lowered, scuffing rate of cylinder bore is lowered, and the economic efficiency and reliability of the engine are enhanced. The cooler is mainly applied to mating power of light duty cross-country cars, light buses, light duty vehicles and light duty passenger-cargo dual-purpose vehicles, and has high practicability.
Description
Technical field
The utility model belongs to the component of internal-combustion engine, relates to a kind of cooler of engine piston, is the improvement of prior art.Be applicable to that the engine piston for high temperature, high load and high-speed motion provides lubricant oil to cool off.
Background technique
In the prior art, the cooler of engine piston mainly is made up of main oil gallery, one group of piston cooling nozzle and the pressure regulator valve that matches with each piston cooling nozzle etc., and structure is complexity, the cost height.
Along with the highway in China transportation is hanged down the pollutionization development towards high speed, economic, comfortable reaching, and the deflation day by day of national energy policy, for satisfying the fuel limit rules of all kinds of light buses, light duty cross-country car, light-duty notchback, light truck, Economy to motor is had higher requirement, realize that these requirements will carry out architecture advances by this class important spare part of countercylinder body, to satisfy the engine performance requirement.
Summary of the invention
The purpose of this utility model is intended to overcome deficiency of the prior art, provides a kind of simple in structure, cooler of producing engine piston easy to install, with the needs of the low pollution of satisfying Europe III emission standard, low fuel oil consumption petrol engine etc.
Content of the present utility model is: a kind of cooler of engine piston comprises: pressure regulator valve, and main oil gallery, piston cooling nozzle is characterized in that: also comprise a secondary oil duct (7); Described pressure regulator valve (1) is arranged between main oil gallery (6) and the secondary oil duct (7), and an end of described piston cooling nozzle is connected with secondary oil duct (7).
In the content of the present utility model: first piston cooling jet (2), second piston cooling nozzle (3), the 3rd piston cooling nozzle (4) and the 4th piston cooling nozzle (5) that described piston cooling nozzle can all be connected with described secondary oil duct (7) for parallel interval setting, an end.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopt the utility model, pressure regulator valve 1 is the oil pressure of a secondary oil duct of control separately, and secondary oil duct shunts machine oil to each piston cooling nozzle, and machine oil sprays from piston cooling nozzle, and piston is cooled off;
(2) the piston cooler that adopts the utility model to provide, the piston that can be high temperature, high load and high-speed motion provides necessary lubricant oil to cool off, help reducing the friction loss of piston, reduce the scuffing of cylinder bore probability, thereby improve the Economy and the reliability of motor;
(3) simple in structure, cost is low, makes easily, produce easy to install, be mainly used in the mating power of light duty cross-country car, light bus, light truck and light-duty notchback, can satisfy the needs of the low pollution of Europe III emission standard, low fuel oil consumption petrol engine etc., practical.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Among the figure: 1-pressure regulator valve, 2-first piston cooling jet, 3-second piston cooling nozzle, 4-the 3rd piston cooling nozzle, 5-the 4th piston cooling nozzle, 6-main oil gallery, the secondary oil duct of 7-.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of cooler of engine piston comprises: pressure regulator valve 1, and main oil gallery 6, piston cooling nozzle also comprises a secondary oil duct 7; Pressure regulator valve 1 is arranged between main oil gallery 6 and the secondary oil duct 7, and an end of piston cooling nozzle is connected with secondary oil duct 7; Described piston cooling nozzle is first piston cooling jet 2, second piston cooling nozzle 3, the 3rd piston cooling nozzle 4 and the 4th piston cooling nozzle 5 that parallel interval setting, an end all are connected with described secondary oil duct 7.
During use, by the initial pressure of the secondary oil duct 7 of pressure regulator valve 1 control; During work, along with the rising of engine speed, its engine oil pressure also constantly raises, and after pressure regulator valve 1 critical pressure value above design, pressure regulator valve 1 is opened, and machine oil enters secondary oil duct 7, thereby each piston cooling nozzle is given in shunting, thereby piston is cooled off; By this embodiment's piston cooling nozzle directly lube pistons inwall, cooling piston top.
The petrol engine that adopts the utility model to provide, emission performance reaches EUR0 III rules, satisfy GB18352.3-2005 " light-duty vehicle pollutant emission limit and method of testing (the III) " mandatory standard that country is about to enforcement, satisfy the local emission standard in DB11/105-1998 and DB11/044-1999 Beijing simultaneously.
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have described good result.
