Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
When the split engine body cylinder cover system is assembled, the cylinder sleeve is usually arranged in the engine body from the top of the engine body when the cylinder sleeve and the engine body are assembled, and then the cylinder cover and the engine body are assembled and the cylinder sleeve is compressed. In order to improve the integration level of an engine, in the prior art, a machine body and a cylinder cover are made into an integrated structure, so that a cylinder sleeve cannot be installed in the machine body, and therefore, the existing integrated machine body cylinder cover system is mostly of a cylinder sleeve-free structure.
However, since the cylinder liner is not provided in the cylinder bore, the cylinder bore cannot be cooled, and thus the capability of improving the power up of the engine is limited. In addition, the cylinder hole honing needs to hoist the whole engine body cylinder cover, and is time-consuming, labor-consuming and difficult to operate.
Based on the above, the embodiment of the application provides an integrated engine body cylinder cover system, an assembling method thereof and an engine, which can not only improve the cooling effect of the engine and the power increasing of the engine, but also facilitate the implementation of honing technology.
Referring to fig. 1 and 2, the integrated engine block cylinder head system in the embodiment of the present application may include a cylinder head 10, an engine block 20, a cylinder liner 100, a crankcase 30, and a main bearing cap 40, wherein the cylinder head 10 is connected to a top of the engine block 20, and the cylinder head 10 and the engine block 20 are in an integrated structure. The crankcase 30 is detachably connected to the bottom of the housing 20, and the main bearing cap 40 is connected to the side of the crankcase 30 facing away from the housing 20. The cylinder block 20 has a cylinder hole 21 formed therein, the cylinder liner 100 is provided on an inner wall of the cylinder hole 21, and a top of the cylinder liner 100 is connected to the cylinder head 10, and a bottom of the cylinder liner 100 is abutted against the crankcase 30.
Referring to fig. 3, the outer wall of the cylinder liner 100 is provided with a cooling water chamber 110, and the cooling water chamber 110 is disposed around the circumference of the cylinder liner 100. The cooling water can be stored in the cooling water cavity 110, and when the engine runs, the cooling water cavity 110 can cool the engine body 20, so that the cooling effect of the engine is improved.
With continued reference to fig. 3, the top of the liner 100, i.e. the side of the liner 100 facing the cylinder head 10, is provided with a recess 120, and the side of the cylinder head 10 facing the liner 100 is provided with a protrusion 11, the protrusion 11 being located in the recess 120. The first fit clearance is formed between the protruding portion 11 and the groove 120, and the first fit clearance can give the deformation allowance to the cylinder cover 10 when the cylinder cover 10 is heated and expanded, so that the cylinder cover 10 is prevented from being extruded and deformed for a long time.
The first fit clearance is herein understood to be the clearance between the top of the boss 11 and the bottom of the recess 120, as well as the clearance between the side walls of the boss 11 and the side walls of the recess 120, that is, the clearance between the surfaces of the boss 11 and the surfaces of the recess 120. Specifically, the first fit clearance may be between 0.4mm and 0.6mm to ensure that the cylinder liner 100 has sufficient deformation space.
With continued reference to fig. 3, a side of the cooling water chamber 110 facing the cylinder head 10 is provided with a first water sealing rubber ring 130, and the first water sealing rubber ring 130 is disposed on the outer wall of the cylinder liner 100 around the circumferential direction of the cylinder liner 100. The first water sealing ring 130 may be used to seal the cooling water in the cooling water chamber 110 to prevent water leakage.
In this embodiment, on one hand, the cylinder cover 10 can play a certain role in positioning the cylinder liner 100 by using the manner that the protrusion 11 can be clamped in the groove 120, on the other hand, the protrusion 11 and the groove 120 can cooperate to form a labyrinth structure, and when the fuel gas in the cylinder liner 100 passes through the gap between the cylinder liner 100 and the cylinder cover 10, the flow path of the fuel gas increases and becomes complex, so that the fuel gas in the cylinder liner 100 can be prevented from flowing to the first water seal ring 130 through the gap between the cylinder liner 100 and the cylinder cover 10, and the first water seal ring 130 is prevented from being burnt in a high-temperature environment.
Referring to fig. 4, a second water sealing rubber ring 140 is disposed at a side of the cooling water cavity 110 facing away from the first water sealing rubber ring 130, and the second water sealing rubber ring 140 is disposed on an outer wall of the cylinder liner 100 around the circumference of the cylinder liner 100. Likewise, the second water sealing rubber ring 140 can be used for sealing the cooling water in the cooling water cavity 110 to prevent water leakage. It can be appreciated that in the embodiment of the present application, the water leakage can be better prevented by providing the water sealing rubber rings on both sides of the cooling water cavity 110 in the axial direction of the cylinder liner 100.
The second water sealing rubber ring 140 is further provided with an oil sealing rubber ring 150 on one side facing away from the cooling water cavity 110, and the oil sealing rubber ring 150 is arranged on the outer wall of the cylinder sleeve 100 around the circumferential direction of the cylinder sleeve 100 so as to be used for sealing engine oil in the crankcase 30.
Referring to fig. 5, a clamping portion 160 is disposed at the bottom of the cylinder liner 100, the clamping portion 160 is disposed on the outer surface of the cylinder liner 100 along the radial direction of the cylinder liner 100, and a clamping groove is disposed on the inner wall of the cylinder hole 21, and the clamping portion 160 is clamped in the clamping groove. Specifically, the side of the clamping groove away from the crankcase 30 is provided with the flange limiting surface 22, and one end of the clamping portion 160 away from the crankcase 30 is abutted against the flange limiting surface 22, so that the clamping portion 160 can be kept fixed under the common abutting action of the flange limiting surface 22 and the crankcase 30.
With continued reference to fig. 5, the side of the clamping portion 160 facing the crankcase 30 is provided with a sealing steel ring 170, and the crankcase 30 may compress the cylinder liner 100 by compressing the sealing steel ring 170. The sealing ring may be used to seal oil and gas in the crankcase 30 from leaking.
In some embodiments, the outer wall of the cylinder liner 100 is further provided with a plurality of positioning strips 101, and the cylinder liner 100 can be positioned with the cylinder holes 21 through the positioning strips 101, so as to ensure the assembly effect of the cylinder liner 100 and the cylinder holes 21. Referring to fig. 3, 4 and 5, a plurality of positioning belts 101 may be disposed on two sides of the first water seal ring 130, between the cooling water cavity 110 and the second water seal ring 140, between the second water seal ring 140 and the oil seal ring 150, and near the crankcase 30, respectively. It can also be understood that the outer wall of the cylinder sleeve 100 is free from special rubber rings, cooling water cavities 110 and other structures, and the rest positions can be provided with positioning belts 101, so that the positioning effect between the cylinder sleeve 100 and the cylinder holes 21 is ensured.
The cylinder sleeve 100 and the cylinder hole 21 are provided with a second fit clearance which is 0.03-0.1 mm, when the engine is in a running state, the cylinder sleeve 100 is heated and expanded, and the cylinder hole 21 can well fix the cylinder sleeve 100.
Referring to fig. 6, a piston 50 is further provided in the cylinder bore 21, the piston 50 being provided at a side of the cylinder liner 100 facing away from the inner wall of the cylinder bore 21, and the piston 50 being reciprocable in the axial direction of the cylinder bore 21. The piston 50 is provided with a piston ring 52 at one side of the piston fire bank 51 facing away from the cylinder cover 10, and a carbon scraping boss 180 protruding towards the piston 50 is arranged at one side of the piston ring 52 facing towards the cylinder cover 10 of the cylinder sleeve 100 along the axial direction of the machine body 20. Since a large amount of carbon deposit is generated in the outer ring of the piston flame bank 51 and the upper region of the piston ring 52 during the operation of the engine, the carbon deposit may abrade the cylinder liner 100 and even cause cylinder pulling, and the excessive carbon deposit can be scraped by the carbon scraping boss 180, so that the cylinder liner 100 can be protected.
As mentioned above, the crankcase 30 is detachably connected to the body 20, and as an embodiment, referring to fig. 7, the body 20 and the crankcase 30 may be positioned by positioning pins, and then the crankcase 30 and the body 20 may be fixedly connected after passing through the crankcase 30 by 4 auxiliary bolts 60. Similarly, the crankcase 30 and the main bearing cap 40 may be positioned by positioning pins, and then 4 main bearing bolts 70 pass through the main bearing cap 40 and the crankcase 30 to be fixed on the machine body 20.
According to the integrated engine body cylinder cover system provided by the embodiment of the application, the cylinder sleeve 100 is arranged in the cylinder hole 21, the cylinder sleeve 100 is provided with the cooling water cavity 110, and the cooling water cavity 110 can cool the engine body 20 in the running process of the engine, so that the cooling effect of the engine is enhanced, and the power rising of the engine is improved. In addition, the integration can be improved, and oil leakage and water leakage between the engine body 20 and the cylinder cover 10 can be avoided.
In addition, when honing an integrated engine cylinder head system, small holes for storing lubricating oil are formed on the inner wall of the cylinder bore so as to lubricate the reciprocating motion of the piston. When the cylinder liner 100 is provided in the embodiment of the present application, the cylinder liner 100 may be honed, and small holes for storing lubricating oil are formed in the inner wall of the cylinder liner 100. Compared with the technical scheme that the whole engine body 20 and the cylinder cover 10 are required to be hoisted in the prior art, the honing process provided by the application only needs to hoist the cylinder sleeve 100, so that the time and the labor are saved, and the operation is convenient.
In the integrated engine body cylinder cover system in the embodiment of the application, when the cylinder sleeve 100 is assembled with the integrated engine body 20 cylinder cover 10, the first water sealing rubber ring 130, the second water sealing rubber ring 140 and the oil sealing rubber ring 150 can be correspondingly assembled on the cylinder sleeve 100, then the cylinder sleeve 100 is assembled from the bottom of the engine body 20, wherein one end of the cylinder sleeve 100 provided with the clamping part 160 faces downwards, one end provided with the groove 120 faces upwards, and finally the cylinder sleeve 100 is assembled in place through the flange limiting surface 22. It should be appreciated that the integrated engine block cylinder head system of the present embodiment solves the existing problem of inability to assemble the cylinder liner 100 by loading the cylinder liner 100 from the bottom of the engine block 20.
Based on the same inventive concept, the embodiment of the present application may also provide an engine, which includes the integrated engine body cylinder cover system in any one of the embodiments of the present application.
Based on the same inventive concept, the embodiment of the application also provides an assembling method of the integrated engine body cylinder cover system, which specifically comprises the following steps:
step S100: placing the cylinder liner 100 into the machine body 20 from the bottom of the machine body 20;
step S200: the crankcase 30 is connected to the body 20 such that the top of the cylinder liner 100 is connected to the cylinder head 10 and the bottom of the cylinder liner 100 abuts the crankcase 30.
In the above step S100, since the cylinder liner 100 is provided with the positioning ring, the cylinder liner 100 and the cylinder hole 21 can be positioned by the positioning ring when the cylinder liner 100 is put into the machine body 20.
In step S200, since the cylinder liner 100 is provided with the engagement portion 160, the cylinder bore 21 has the flange stopper surface 22, and when the bottom of the cylinder liner 100 is brought into contact with the crankcase 30, specifically, one end of the engagement portion 160 facing away from the crankcase 30 may be brought into contact with the flange stopper surface 22, and one end of the engagement portion 160 facing the crankcase 30 may be brought into contact with the crankcase 30.
