Abstract
The utility model provides a wet sleeve capable of reducing caking and achieving carbon deposit. The wet sleeve comprises a sleeve body. A plurality of annular grooves with the carbon deposit function are formed in the upper end of the inner side wall of the sleeve body, an upper waistband, a middle waistband and a lower waistband are arranged on the upper portion, the middle portion and the lower portion of the outer side wall of the sleeve body respectively, the middle waistband is provided with a sealing groove, and a sealing ring is arranged in the sealing groove. Water via grooves for cold water to pass are formed between the upper waistband and the middle waistband and between the middle waistband and the lower waistband respectively. A plurality of rows of spherical protruding parts are evenly distributed on the circumferences of the bottom faces of the water via grooves, the height of each spherical protruding part is smaller than the depth of each water via groove, and the surfaces of the water via grooves and the surfaces of the spherical concave parts are plated with rust-proof high-temperature-resistant composite ceramic layers. The wet sleeve is good in heat dissipation ability and temperature reduction ability and can reduce caking; because the grooves with the carbon deposit function are formed in the upper end of the inner side wall of the sleeve body, the amount of carbon on the surface of a piston and the amount of carbon on the inner wall of the sleeve body can be reduced, friction is reduced, the dosage of lubricating agents is reduced, the work doing efficiency of the piston is improved, and the service life of an engine is prolonged.
Description
Technical field
The utility model relates to the cylinder sleeve in a kind of motor car engine, more particularly relates to a kind of energy and reduces wet cylinder liner coking and energy carbon deposit.
Background technique
Along with social development, the raising of people's living standard, automobile is seen everywhere, automobile relies on motor to carry out work, due at cylinder internal surface owing to being subject to the effect of high-temperature high-pressure fuel gas and contact with the piston of high-speed motion and very easily wear and tear.For improving the wear resistance of cylinder and extending the working life of cylinder and have different air cylinder structure form and surface treatment method.Air cylinder structure form has three kinds: without cylinder shell type, dry gas cylinder sleeve type, moisture cylinder sleeve type.
Wet liner outer wall directly contacts with cooling liquid, water channel is communicated with cylinder barrel large size, by cylinder sleeve, isolate cooling water and cylinder working room completely, wall thickness 5-8mm, utilization is located up and down endless belt and is realized radial location, and axially locating coordinates realization by cylinder liner upper flange with the corresponding supporting surface in body top.The advantage of wet liner is the water jacket that there is no sealing in cylinder block, and easily casting, conducts heat, and cooling effect also better, temperature distribution is more even, repairs conveniently, will from automobile, not pull down with regard to replaceable cylinder liner by motor.
Owing to being subject to high-temperature high-pressure fuel gas effect, wet liner is carbon deposit in piston face and cylinder sleeve body easily, after piston face and cylinder sleeve inner body wall carbon deposit, increased the friction between piston and cylinder sleeve inner body wall, reduced the mechanical efficiency of piston, also increased the consumption of oiling agent, the working life of having reduced to a certain extent motor simultaneously.Meanwhile, carbon deposit, along with the discharge of waste gas, also easily increases the weight of the pollution of environment.
Model utility content
The purpose of this utility model is to provide a kind of can reduce coking generation and wet cylinder liner that can carbon deposit, with the cylinder sleeve that overcomes prior art easily at cylinder sleeve inner body wall and piston face carbon deposit, increase the defect of lubricant quantity and reduction engine operation efficiency.
The purpose of this utility model realizes by the following technical solutions:
Can reduce a wet cylinder liner coking and can carbon deposit, comprise cylinder sleeve body, the madial wall upper end of described cylinder sleeve body arrange many ring-types can carbon deposit groove; The upper, middle and lower of the outer side wall of described cylinder sleeve body arranges waistband, middle waistband and lower waistband, on described middle waistband, is provided with seal groove, is provided with seal ring in seal groove; Between described upper waistband and middle waistband, between middle waistband and lower waistband, form the tank of crossing by cooling water; The bottom surface of described tank excessively arranges the ball bumps of many row's multiple rows along even circumferential, the height of described ball bumps was less than the degree of depth of tank, and the described surface of tank excessively and the surface of ball bumps arrange the composite ceramic layer of Rustproof high-temperature resisting.
As the improvement to technique scheme, the thickness of described composite ceramic layer is 0.1～0.2 ㎜.
As the improvement to technique scheme, the surface of described groove is rough surface.
Compared with prior art, the utility model has the advantage of: on cylinder sleeve body outer side wall, be provided with two by the tank of crossing of cooling water, the bottom surface of crossing tank is provided with ball bumps, can increase the contact surface area of cooling water and cylinder sleeve body, strengthen heat dissipation potential, temperature reduction performance is good, reduce coking generation, the described surface of tank excessively and the surface of ball bumps arrange the composite ceramic layer of Rustproof high-temperature resisting, make cylinder sleeve have resistance to superior high-temp anti-corrosion performance, good stability; The madial wall upper end of cylinder sleeve body is provided with groove that can carbon deposit, the a small amount of charcoal producing when piston moves in cylinder sleeve body, can be accumulated in groove, thereby reduce the charcoal amount of piston face and cylinder sleeve inner body wall, reduce friction, and then minimizing lubricant quantity, accelerate piston mechanical efficiency, increase engine life.
