And the perforate gross area of all louvres is more than the perforate gross area of piston pin bore.
Oil scraper ring groove is provided with below piston skirt described in the utility model, spill radiating groove is provided with below oil scraper ring groove,
Several small circular louvres are provided with spill radiating groove.
Symmetrically arranged louvre described in the utility model is shaped as semicircle, arc, trapezoidal, square, prismatic, many arris
Angular, oval or triangle, on piston skirt the perforate gross area of all louvres account for piston skirt whole circumference face 30-
45%.
Longitudinal long trough louvre described in the utility model is made up of or by multistage longitudinal direction one section of continuous rectangular through holes
The short square through hole being arranged in a row is constituted.
Bottom of the bottom of longitudinal long trough louvre less than other louvres on piston skirt.
The durable piston of the utility model engine louvre larger due to offering perforated area on piston skirt, radiating
The gross area in hole accounts for 30-the 45% of piston skirt whole circumference face, up to 6492mm2, the attrition surface 52% of piston skirt is reduced,
Resistance reduces when engine works, faster rotational speed, power output increase, saves so oil, improves the use longevity of piston and engine
Life；And the utility model is additionally provided with the louvre of longitudinal long trough on piston skirt, it is possible to achieve the oil pressure for automatically adjusting
Power, further improves operating efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the durable piston of the utility model engine.
Fig. 2 is that the right side of Fig. 1 regards schematic diagram.
Specific embodiment
The structure to the durable piston of the utility model engine is further described below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, the durable piston of the utility model engine includes piston skirt 10, and the top of piston skirt 10 is provided with
Oil ring groove 2 with together with of twice compression 1, are provided with several small circular holes louvres 4 on oil ring groove 2, piston is provided with piston skirt 10
Key seat hole 7 and several to longitudinal (the longitudinal long trough louvres 9 of long trough louvre 9 of symmetrically arranged big louvre 3 and a pair
Can be arranged as required to as multipair), perforate of the perforate gross area of all louvres more than piston pin bore 7 on piston skirt 10
The gross area, and the gross area of louvre accounts for 30-the 45% of piston skirt whole circumference face, up to 6492mm2, reduce piston skirt
Attrition surface 52%.
The utility model is provided with oil scraper ring groove 8 in the lower section of piston skirt 10, and the lower section of oil scraper ring groove 8 is provided with spill radiating groove
6, several small circular louvres 5 are provided with spill radiating groove 6.
Big louvre 3 shape of the utility model on piston skirt 10 could be arranged to semicircle, arc, it is trapezoidal, square,
The shapes such as prismatic, polygon angular, oval or triangle.
Longitudinal long trough louvre 9 described in the utility model can be made up of one section of continuous rectangular through holes, it is also possible to by
The short square through hole that multistage is longitudinally arranged in a row is constituted.
By the elastic piston ring that the roads of head Shi You tri- of existing piston have relatively strength is support, the body portion of piston
(in, bottom) is vacantly hung in cylinder by the ring of head, when piston work done needs left and right commutation motion, even
In forcing piston in the presence of bar and piston pin, bottom and cylinder wall or so tap, cause the abrasion of piston, and influence piston ring
Elasticity.And the utility model can overcome above mentioned problem by opening up the larger louvre of area on piston skirt 10, and
Big louvre 3 is located at the surface of bent axle fuel feeding block (also known as balance weight, get rid of oil clot).Fuel feeding block gets rid of machine oil when engine is operated
Go out in the middle of the space entered between the underlying piston of big louvre 3 and casing wall behind the hole of footpath, the lower section of big louvre 3 is provided with gear oil
Annular groove 8, makes machine oil not down to be lost in again after entering the space between piston and casing wall, and one oil groove is formd in whole circumference
With oily band, and due to longitudinal long trough louvre 9 bottom less than big louvre 3 bottom, when oil groove inner engine oil crosses Sheng
When, oil flows back to oil storage basin from longitudinal long trough louvre 9.Storage oil mass of the engine in slow train (during the slow-speed of revolution) is remain,
The piston lower portion that be suspended on when piston is in commutation forces piston to be extruded to casing wall, at this moment in the presence of connecting rod and piston pin
The machine oil of storage is pressurized, and generates a kind of opposite force and heads on piston, it is to avoid piston produces percussion with casing wall, when engine accelerates
The side force that bent axle is delivered on piston by connecting rod and piston increases, and the oil level of original storage is insufficient to prevent piston and casing wall
Percussion, at this moment bent axle get rid of oil clot with engine speed accelerate and increase fuel delivery, according to rotating speed allocate fuel delivery, fuel feeding
Big reverse prevention power between piston and casing wall becomes big, otherwise diminishes.The big louvre that the utility model is opened up on piston skirt
3, not only with above-mentioned effect, and piston weight in itself can also be alleviated so that engine is operationally produced
Radial load reduces, and piston commutating speed when moving up and down is fast, while can reduce the percussion of piston and cylinder again so that shipping machine
Dynamic to turn smooth-going, resistance is smaller, improves the power output of engine, saves fuel oil and durable, extends engine life.
Longitudinal long trough louvre 9 that the utility model is opened up on piston skirt, is effectively equivalent to be installed on oil groove
An engine oil pressure valve for automatically adjusting is gone up, it can be produced according to the speed of the size and engine speed of getting rid of block fuel delivery
Different suction are given birth to discharge the machine oil in oil groove.When engine speed is slow, fuel feeding block gets rid of the oil level into oil groove
It is few, if remaining machine oil can only overflow oil return basin from the lower portion of longitudinal long trough louvre 9.When engine speed is accelerated
Oil flows out to oil tray from longitudinal long trough louvre 9 when fuel delivery increases, and when engine is when running at high speed, fuel delivery is bigger
When, produced pull of vacuum is suctioned out and returns to oil tray when machine oil now is by piston fast downlink.
The utility model opens up spill radiating groove 6 and small circular louvre 5 below piston skirt, and piston is carried with casing wall
More preferable lubrication and radiating has been supplied to avoid high temperature.
