Abstract
The utility model discloses an engine cylinder with a ceramic-processed internal surface, which comprises a cylinder body. A cylinder sleeve is inlaid in the cylinder body. An alloy ceramic layer is composited on the inner wall of the cylinder sleeve through static reaction. The utility model has the advantages that the durability is high, the horsepower of the engine can be effectively promoted, the oil consumption is reduced and the engine cylinder can be widely used for the motorcycle industry and small petrol engines, especially for long-time working practical power aspects such as lawn mowers, chain saws and the like.
Description
Technical field
The utility model relates to a kind of cylinder, the cylinder that particularly a kind of internal surface is handled through pottery.
Background technique
Because the piston of motor is to do to-and-fro motion at a high speed in the cylinder barrel of its cylinder block.So, require the inwall of its cylinder barrel that excellent abrasion resistance energy and easily lubricated performance will be arranged.At present, great majority start the locomotive cylinder all to adopt two kinds of full cast iron cylinder and aluminium alloy cylinders, are the cylinder of cylinder body with cast iron wherein, are characterized in that hardness is high so wear resistance is good, but Heavy Weight and thermal diffusivity not good be its shortcoming.And the characteristics of aluminium alloy cylinder be in light weight, thermal diffusivity is very fast.Though aluminum alloy itself is firm but wear no resistance, therefore the friction in the time of therefore must just standing engine running in conjunction with cast iron liners also makes the radiating effect of cylinder beat some discounts.And " heat " is exactly the life-span of engine to the influence of engine maximum, when engine temperature is too high, can significantly reduce the life-span of engine, even influence the breakage of part vital part, causes client's very big puzzlement in maintenance.With engine carbon distribution phenomenon is that example illustrates: will influence the compression ratio of firing chamber when engine carbon distribution situation is serious, causes a horsepower bust, even produce pinking.And carbon distribution is too much, also will influence the motility and the smoothness of piston.And the source main cause of carbon distribution is that exactly the engine cylinder temperature is too high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the cylinder that the utility model provides a kind of internal surface to handle through pottery.
The technological scheme that the utility model adopted is:
The cylinder that a kind of internal surface is handled through pottery, it comprises cylinder block, is installed with cylinder sleeve in the cylinder block, inboard wall of cylinder liner is compounded with the ceramal layer by the static reaction;
As improvement of the technical scheme, described ceramal layer is a Ni-SiC ceramal layer;
As further improvement in the technical proposal, described ceramal layer thickness is 0.04-0.10mm.
The beneficial effects of the utility model are: in the time of this production, at first use a kind of materials processing close to go out cylinder sleeve with piston, during casting cylinder sleeve is bumped in the cylinder block, after reprocessing certain cylinder dimensions, inboard wall of cylinder liner is carried out special processing, adopt the method for static reaction, to the compound coating layer of Ni of cylinder wall-SiC ceramal layer, be made through precise finish at last, the casing wall store oil of this product is good, and ceramic layer thickness is 0.04-0.10mm, and its hardness can reach HV520 ~ 700, its durability is good, can effectively promote the horsepower of engine, reduce oil consumption, thereby can be widely used in motorcycle industry, miniature gasoline engine, be specially adapted to long practicability power aspect of operating time, as mowing machine, chain saw etc.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure sectional view of the present utility model.
Embodiment
With reference to Fig. 1, the cylinder that a kind of internal surface is handled through pottery, it comprises cylinder block 1, is installed with cylinder sleeve 2 in the cylinder block 1, cylinder sleeve 2 inwalls are compounded with ceramal layer 3 by the static reaction.
In the time of this production, at first use a kind of materials processing close to go out cylinder sleeve 2 with piston, during casting cylinder sleeve 2 is bumped in the cylinder block 1, after reprocessing certain cylinder dimensions, cylinder sleeve 2 inwalls are carried out special processing, adopt the method for static reaction, to the compound coating layer of Ni of cylinder wall-SiC ceramal layer 3, be made through precise finish at last, the casing wall store oil of this product is good, and ceramic layer 3 thickness are 0.04-0.10mm, and its hardness can reach HV520 ~ 700, its durability is good, can effectively promote the horsepower of engine, reduce oil consumption, thereby can be widely used in motorcycle industry, miniature gasoline engine, be specially adapted to long practicability power aspect of operating time, as mowing machine, chain saw etc.
Claims (3)
