Abstract
The utility model provides a cylinder jacket working face lubricating structure, the piston friction region that is located the cylinder jacket is located, cylinder jacket working face lubricating structure is equipped with a plurality of oil storage spots with piston contact's surface, oil storage spot equipartition is in cylinder jacket working face lubricating structure's surface, and the oil storage dimple gathers in the oil storage spot, the utility model discloses a set up the oil storage dimple, can improve the lubricating quality, reduce the wearing and tearing of internal -combustion engine cylinder jacket and piston, reduce oil consumption and exhaust emission to reach energy saving and emission reduction's effect.
Description
Technical field
This utility model relates to field of internal combustion engine, especially a kind of cylinder jacket work surface lubrication system.
Background technology
The interior surface of cylinder liner of internal combustion engine smooths now, and lubricating oil is difficult to keep on interior surface of cylinder liner, causes lubrication
Oil skewness so that under current techniques, piston has become the main of internal combustion engine development with the friction of cylinder jacket, lubrication problem
One of problem, piston moves back and forth in cylinder jacket and easily accumulates amount of heat. when the temperature increases, lubricating oil film easily by every
Open, make piston and cylinder jacket occur that dry friction causes serious abrasion, affect the service life of piston and cylinder jacket, even produce
The phenomenon of burn oil, makes the consumption of machine oil increase, and can strengthen waste gas discharge and cause pollution.
Summary of the invention
The utility model proposes a kind of cylinder jacket work surface lubrication system, by arranging the micro-hole of oil storage, lubrication matter can be improved
Amount, reduces cylinder jacket of diesel engine and the abrasion of piston, reduces oil consumption and waste gas discharge, thus reaches the effect of energy-saving and emission-reduction
Really.
This utility model is by the following technical solutions.
A kind of cylinder jacket work surface lubrication system, is positioned at the piston friction region of cylinder jacket, described cylinder jacket work surface
Lubrication system is provided with some oil storage speckles with the surface of piston contact, and described oil storage speckle is distributed in cylinder jacket work surface lubrication system
Surface, the micro-hole of oil storage of gathering in oil storage speckle.
The degree of depth in the micro-hole of described oil storage is at below 0.006mm, and the mouth diameters in the micro-hole of oil storage is at below 0.04mm, with a storage
In oil mark, the spacing in the micro-hole of adjacent oil storage is at below 0.7mm.
In this utility model, described cylinder jacket work surface lubrication system is provided with some oil storage speckles with the surface of piston contact,
The densely covered micro-hole of oil storage in oil storage speckle;The degree of depth in the micro-hole of described oil storage is at below 0.006mm, and the mouth diameters in the micro-hole of oil storage exists
Below 0.04mm, with in an oil storage speckle, the spacing in the micro-hole of adjacent oil storage is at below 0.7mm;Owing to have employed above scheme so that
Enable lubricating oil adsorption storage in the pit that these are small, set up the dynamically lubricating with piston at interior surface of cylinder liner,
Under the conditions of engine work, the friction pair that cylinder jacket and piston ring are formed contact surface in whole stroke can be oily
Film covers, and therefore reduces the abrasion of cylinder jacket of diesel engine and piston, thus avoids piston ring with cylinder jacket because friction is overheated
And the burn oil caused, and the waste gas emission problem caused due to oil firing.
In this utility model, described oil storage speckle is distributed in the surface of cylinder jacket work surface lubrication system;This structure makes lubrication
Oil is evenly distributed in cylinder jacket, and during work, piston ring contacts with the oil film of pit surface, improves lubricating quality.
In this utility model, described cylinder jacket work surface lubrication system is provided with some oil storage speckles with the surface of piston contact;
This design makes the oil storage face of cylinder jacket work surface and interval, non-oil storage face arrange, and in friction pair work process, lubricating oil can
To shift between different oil storage speckles, allow lubricating oil more uniformly spread, and this spacer structure also can effectively promote and rub
Wipe the fineness in subtask face, reduce service wear.
Accompanying drawing explanation
Explanation further details of to this utility model with detailed description of the invention below in conjunction with the accompanying drawings:
Accompanying drawing 1 is schematic diagram of the present utility model;
Accompanying drawing 2 is the close-up schematic view at the A of Fig. 1;
In figure: the micro-hole of 1-oil storage;2-cylinder jacket;3-cylinder block;4-oil storage speckle.
Detailed description of the invention
As shown in Figure 1, 2, a kind of cylinder jacket work surface lubrication system, it is positioned at the piston friction region of cylinder jacket, described
Cylinder jacket work surface lubrication system is provided with some oil storage speckles 4 with the surface of piston contact, and described oil storage speckle 4 is distributed in cylinder jacket work
Make the surface of face lubrication system, the micro-hole of oil storage 1 of gathering in oil storage speckle.
The degree of depth in the micro-hole of described oil storage 1 is at below 0.006mm, and the mouth diameters in the micro-hole of oil storage 1 is at below 0.04mm, with individual
In oil storage speckle 4, the spacing in the micro-hole of adjacent oil storage is at below 0.7mm.
Embodiment:
When oil addition in cylinder jacket, due to capillarity, lubricating oil can be by partial adsorbates in the storage of oil storage speckle 4
Store at oil micropore 1, when in piston cylinder jacket 2 in cylinder block 3 toward polyslip, under frictional heat and pressure effect, storage
Lubricating oil in oil mark is extruded, and overflow is lubricated on rubbing surface, when piston does not works, and overflow profit on rubbing surface
Lubricating oil can be sucked back by oil storage speckle again.
