Abstract
A cooling nozzle of a piston of a motor with a double balance shaft is characterized by essentially comprising a hollow valve body, a spring, a steel ball, a plug, a spray pipe and an installing support. The hollow valve body is provided with an oil outlet, an oil inlet which is provided with an annular platform, the spring, and the steel ball arranged between the spring and the circular platform. One end of the plug is connected fixedly and hermetically with the valve body, the other end of the plug is arranged inside the valve body and movably sleeved with the spring, one end of the spray pipe is fixedly communicated with the oil outlet of the valve body, and the installing support is connected with or integrated with the valve body. The cooling nozzle can provide necessary lubricating oil to cool the piston which is high in temperature, working load and moving speed, thereby being favorable for reducing friction loss of the piston and probability of a cylinder scuffing, and increasing economy and reliability of the motor. The cooling nozzle is mainly used in mating powers of a light sports utility vehicle, a light bus, a light motor truck and a light station wagon, and the practical applicability is wide.
Description
Technical field
The utility model belongs to the component of internal-combustion engine, relates to a kind of cooling jet with engine piston of double balance shaft.Be applicable to that the petrol engine piston for high temperature, high load and high-speed motion provides lubricant oil to cool off.
Background technique
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, provide a kind of simple in structure, cooling jet of producing the engine piston with double balance shaft 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 cooling jet with engine piston of double balance shaft, it is characterized in that: mainly annular table (1c) is arranged by having in oil inlet hole (1a) and the oil inlet hole (1a), and the hollow valve body (1) of oil outlet (1b) arranged, place the spring (5) in the valve body (1), place the steel ball (6) between valve body (1) inner spring (5) and the annular table (1c), one end and valve body (1) fixed seal connection, the other end be positioned at valve body (1) and with the obstruction (4) of spring (5) pivot bush unit, the jet pipe (2) that one end and the oil outlet (1b) of valve body (1) fixedly are communicated with, and fixedly connected with valve body (1) or the mounting bracket (3) that is connected as a single entity constitutes.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) piston cooling nozzle 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;
(2) 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;
Fig. 2 is the plan structure schematic representation of Fig. 1.
Among the figure: 1-valve body, 1a-oil inlet hole, 1b-oil outlet, 1c-annular table, 2-jet pipe, 3-mounting bracket, 4-obstruction, 5-spring, 6-steel ball.
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 cooling jet with engine piston of double balance shaft, main by the hollow valve body 1 that annular table 1c is arranged in oil inlet hole 1a and the oil inlet hole 1a and oil outlet 1b is arranged is arranged, place the spring 5 in the valve body 1, place the steel ball 6 between valve body 1 inner spring 5 and the annular table 1c, one end and valve body 1 fixed seal connection, the other end be positioned at valve body 1 and with the obstruction 4 of spring 5 pivot bush units, the jet pipe 2 that one end and the oil outlet 1b of valve body 1 fixedly are communicated with, and the mounting bracket 3 of fixedlying connected with valve body 1 constitutes.
It is 3 millimeters that this embodiment designs oil inlet hole 1a diameter, and oil spout cracking pressure (being the pressure that steel ball 6 is removed sealing oil inlet hole 1a) for 0.2MPa, as required, also can design different parameters, regulates nozzle oil spout initial pressure, to guarantee favorable cooling effect.
During use, adopt bolts that the present embodiment nozzle is installed on the engine cylinder body by mounting bracket 3, the oil inlet hole 1a of valve body 1 is connected with the main oil gallery of engine lubrication system, jet pipe 2 arrives the engine piston top inner wall with oil injection.During work, along with the rising of engine speed, its engine oil pressure also constantly raises, after the critical pressure value above design, spring is compressed, and oil enters valve body 1 in and washes steel ball 6 open, enters piston head, recirculation from oil outlet 1b through jet pipe 2 injections again through main oil gallery, oil inlet hole 1a; 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.
