Description of the Invention (1) The invention is based on an internal combustion eaves, specifically, a cylinder sleeve for a two-hengcheng crosshead engine. This cylinder The bushing has a pain that can be moved in this bushing, and it is set to move between the bottom dead point and the upper dead stick. At this bottom dead point, each suffocation port in the wall of the cylinder bushing is #chiped in The top surface of the piston is above, and the upper piston is located in the farthest position of the piston in the cylinder liner. The piston is provided with several pistons, and the outer surface of each piston ring moves along the inner surface of the sleeve. The cylinder liner is provided with a plurality of inner divisions on the inner surface. Each inner division is positioned at the relative position of each inner cylinder. The airflow connection path between the upper and lower space of a piston can be known. "For this type of cylinder liner, refer to Japanese patent JP-A 62-26346. In this document, in order to reduce the pressure over the first piston Lowering and enabling a uniform pressure drop across all pistons, provision is made for each internal gap to be provided in the inner surface of the airlock liner. Each inner cymbal is immersed in a large depth and has a normal surface slightly larger than the piston ring inwardly of the bushings. During the compression of the piston, these internal divisions act as a charge.小 Compressed air is a small air chamber. After passing through the inner chambers, the compressed air enters the bright space below the piston and thus increases the pressure under the piston ring. The lower 8 force drop is small. The superior stickiness of this kind of conventional cylinder liner is also mentioned in this document. Filling the space between the pistons with "clean and compressed air can offset each ring eaves and inner sleeve Defiled face. It is well known that if each piston can provide an air leak slot to meet the piston's gas brewing, it can reduce its pressure drop on the piston ring and thus reduce the wear of the piston. However, this type of air leakage groove is likely to cause high-load pistons to be affected. 3- (Please read the note on the back before filling in this page) d ▼ Package.

Description of the invention (*) Mechanical weakening, thus reducing the service life of the piston. In addition, the defect caused by the formation of air leakage in the piston is caused by the piston ring being hit by the hot air flowing downward from the air leakage groove in the material of the circumference of each air leakage groove and in the upper piston can. "Every face is violent in the face" is under Gao Yan's color chips. In the new internal combustion engine, especially in the two-hengcheng ten-head engine, the combustion pressure and the average effective pressure are extremely far apart. As a result, the pressure difference on each piston ring is extremely large. Therefore, it may be possible on each piston ring and the liner. The casing causes considerable wear β. Therefore, the purpose of the present invention is to improve the operating conditions and service life of each piston ring and cylinder liner, and to generate only a very small negative alum in the efficiency of the engine. Because of this, the cylinder liner according to the present invention is particularly characterized in that when the piston sticks on it, it is at least partially internally positioned in the relative position of the first piston ring, and viewed from the longitudinal direction of the liner. In other words, the range of each internal call is at least twice the distance of the first piston. When the piston is at its top dead point, the position of each internal division in the inner bushing is in the first piston. In the relative position, this position represents a strong pressure increase in the combustion chamber above the piston due to the beginning of combustion. As a result, the gas leakage from the combustion gas is generated through the internal combustion chambers and flows below the upper piston or the piston. , So that the pressure difference between the piston or the piston can be reduced when the pressure is maximum and the timing of the engine cycle. This situation can effectively reduce the wear of the piston and the cylinder liner. When the piston a is moved from the upper dead stick to the lower end, each of the moving parts slides on the bushing part without the inner part and thus no air leakage is generated. In the paper size of the paper, the national standard (CNS) A4 (210X297 mm) is applicable (please read the note ^^ on the back before filling this page) ^ ------ 1 ^ ----- J Line --------.— IUI ..—— 印 Printed A7 B7 by Zhengong Consumer Cooperative, Central Bureau of the Ministry of Economic Affairs_V. Description of Invention (3) During the period of Qing Xunchen ’s sore The K force on the piston is low, so the same problem occurs without wear on the upper dead sticky circle. Compared with the position of the air leak groove in each piston, the cylinder liner of the present invention can be embroidered. It is mentioned that the following excellent viscosity, which plays an important role in engine efficiency, is only used when the position of the piston is close to the top dead center, and the implosion in the inner surface of the bushing is leaked in the relative position of the pistons. Gas to the bottom of each piston. The other excellent result is that the heat obtained in the materials of each Chen Zhouyuan is relatively small, mainly due to the fact that the combustion gas flows through the inner cylinders in a relatively small part of the engine cycle. The formation of radon and its length are larger than the distance of the first piston 珲, which causes the combustion gas to circulate through the piston ring / piston 瓌 during a long period of ore holding time, and the design of this internal aging is not Ying Xin holds up in the space of the pistons, but the pain difference can be achieved only by having a small leakage of air flow through the unit time. Therefore, the internal leakage area can be reduced, and furthermore, it can be further restricted to be affected by the local thermal directors on the cover materials of the inner gaps and reduce the stress concentration in these materials. In terms of internal positioning for leak detection in the internal phase, at least the first piston schenkel is formed without such a leak groove, so that the strength of each piston ring can be reduced and the manufacture of the piston stern can be avoided. The piston material of the bushing material fcb is more resistant to temperature. The upper part of the bushing material is generally cooled by the cooling holes to remove the heat M supplied to this material. Each inner division is positioned in the upper part of the inner bushing surface and also has another excellent adhesion, that is, each inner division is within the area of a bushing.

Description of the invention (4) level The thermal stress makes the rated stress level in this area compressive stress. This situation can reduce the risk of forming fatigue cracks in the materials except the week garden. In addition, this invention 3-excellent The wear rate of the cylinder liner is usually slower than the wear rate of each piston. Therefore, the area of air leakage maintained by a certain size in each interior is longer than the holding time of the air leakage eaves in the outer surface of each piston. Printed by the Central Labor Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative (please read the "$" on the back, and then fill out this page). In a priority application example, the kit has at least three sets of internal divisions, of which the first Within the group_ are located in the relative position of the first piston, and each in the second group The internal suspicions are located in the relative position of the second piston and are shifted in the circumferential direction of the bushing in the other groups. As for the internal division in the third group, when the piston is at its upper dead point, Each inner division is located in the relative position of the third piston, and each inner cylinder in the second group is extended in the length portion of the bushing, and at least there are each of the first and third groups in the length portion. _Partially positioned β The three sets of internal fog can be controlled not only on the first piston, but also on the two sides of the piston, which are connected to the piston, and the gas pass through the air, and thus controlled in the three pistons. The pressure difference on the "In this example, when the stupid is dead on it," there is only one set of internal constriction, the length of which can be extended through two or three top pistons " However, this situation does not allow each internal elimination energy control to control the pressure difference on each piston. In this example of priority use, when the piston is moving downwards, there is an internal division. In the S domain, the inner gaps of the second group can ensure that the continuous ore leakage of the combustion gas can reach that of the first piston. On the other hand, the displacement of each internal division of the second group to the other internal divisions on _ week can force the air leak to meet a piston ring before passing the ore flow before the ore flow direction.

Description of the flow in the invention (S), if possible, it can also flow down to the vicinity of the piston. This extension of the flow profile can cool the leak. Because the flow of leaked air is transferred from one group to the other, it can produce favorable pressure loss in the discouraged. Internal division can be divided into many groups, and it can also provide its advantages. The lower surface of the piston ring is also encountered when the piston leaves the upper sticky downward lotus candy which is removed in each of the different groups, and the volume of the air is gradually reduced. In further development, each of the third group Except that they are located on the extensions of the first group and have a common meteorological portion inward of each internal division, the size is larger than the height between the second piston ring and the second piston ring. " When the piston is near the top dead center, the second piston ring is located The relative positions of the inner gap isolation parts of the first and third groups can prevent the gas in the combustion chamber from flowing directly from the first piston ring down to the bottom of the third piston β. In addition, because the internal Located in its extension direction, it is more advantageous in manufacturing. Printed by the Central Laboratories Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative (please read the precautions on the back before filling this page). At least one of the bushings in the longitudinal position is suitable for at least four inner divisions on the periphery of the bushing, and at least "It is advisable to divide by eight." If viewed in the circumferential direction, these divisions are alternately divided into the second group and the first or third group respectively, and the total leakage surface area is allocated on more internal gaps. It can make the cross section of the inner part less annihilation and distribute the heat in the leaky air to several positions, so that the local heating becomes lower, depending on the vertical position in the bushing, it will be at the first place. It is more advantageous than the long-distance route of the air flow that passes through all the internal gaps mentioned above to enter one of the second group.

In addition to this, the airflow path may be extended »or some of the inner gaps in the first and third groups are connected to provide direct airflow 9 please but 9 this The measure is not the desired solution. Read to minimize the pressure loss from the combustion chamber. »When the piston sticks on the back side 9 The construction of the bushing makes the piston skirt painted. There is no internal elongation underneath the active m. Therefore, the piston ψ item C on the piston can be cut down completely to the combustion chamber. The flute piston f% is installed in all parts. Except when m is in the relative position, only in a short period of time Page 1 I there is air leakage downward to the bottom of the top three loops P 1 1 in the first The maximum m on the piston ring must be reduced to the pressure difference on one piston. 1 I 0 In an example, 9 each internal clearance is formed only through m. Three uppermost pistons are cut. One or more channels of the piston ring are connected by airflow. 9 At this time, the piston is located at a position where the crankshaft angle is zero degrees and the position between the pistons and the positions of the pistons is the first.

Description of the invention (7) 穑, the unit is square millimeters · If the air leakage surface 稹 becomes l: bD2 / 7D00 0 square millimeters, then The pressure difference above becomes large enough, which results in a high flow rate of the gas and increases the heat load in the material of the inner dividing surface, and causes considerable wear on the piston and the bush. If the air leakage area becomes ItD2 / 2D Ofl square millimeter, the pressure difference on the piston will become very small, making it difficult for Live Mizu to tightly seal on the inner side of the cylinder liner. The danger of igniting pressure on the piston partly incurs the danger of escape from the living body. "As is well known, it is shown in other published documents of EP-B 0 5 58 5 83, above the cylinder liner. Some may provide many cooling holes, and the longitudinal curve of each hole is inclined to the squall line of the bushing. "If such bushings are used with the bushing of the present invention, the inner vertical wheel line is essentially It is parallel to the longitudinal line adjacent to the cooling hole. This internal division route can promote the elimination of the heat M supplied from the article, so that the level of the degree in the material of each inner periphery can be maintained at a reasonable level. Low level and as much as possible along the entire length of the sickle. This public document explains how to use a filter to install or remove a cold portion that flows out of the part of the cooling hole closest to the inner surface of the bushing. The cooling strength of each inclined cooling hole is control. If the inner pans are extended in the relative position of a cooling hole, the filter in the cooling hole can be moved to the opposite portion of the inner pan, so that the cooling in this position is stronger than the region that is not close to the inner division. Used as an alternative measure to increase the cooling effect in the relative position of each internal division. The bushing according to the present invention can be further developed so that the cylinder liner has a number of tilting cooling holes evenly distributed on the periphery of the liner, and毎 一 (Please read the note on the back of the page before filling in this page) 0 Pack · 1Τ- • ο The size of the paper used in the national solid standard (CNS) Α4 specification (210X2.97 mm) 5.

Here is an example to explain as follows: If the gas rainbow bushing 1 shown in the 5th item has an inner diameter of 600 public housing, in the case of four strips, it is suitable to make each strip in each group _ 5mm ， 在 The cross-sectional area of about 12.5 square millimeters, the area of the inner gap in the direction of the circle shoulder is about 9 mm and the depth of the inner gap is about 2.5 mm in the radial direction. In this case, the inner cymbal has a cross-sectional shape and is favorable for the stress aspect as shown in Section 6; viewed from the «I side of the piston, the bottom has a concave middle portion and is flat". Entering the ft wall portion of the two inclined convex surfaces, this supply wall portion passes in the tangential direction and enters the inner side surface 13 of the bushing. When the bushing is worn by the engine operation, the inner German surface 13 has been thinned to a certain extent Distance into each inner division, so the inner division area is reduced. If the air leakage surface is close to the low limit, Bfl must re-machine the bushing and determine the shape of the inner gap. The liners having the respective internal gaps according to the present invention can also be manufactured according to the used cylinder liners. For the replacement of piston rings, such as the replacement of the first piston chen, each internal division 2 5-2 7 can be cut and processed in the inner bushing surface at the opposite and longitudinal position of each cooling hole.

Bushings can also form a group or earn more than three groups. When the piston is at its top dead point, one or more sets of inner linings may be located at a lower position than the skirt piston, but if the inner cymbals are extended in the bushing and extend downward and exceed the lubrication The relative position of the oil rail 11, then this -16- This paper size applies to the Chinese national standard (CNS > Λ4 size (210X297 mm)
