Description
Affiliated technical field
The utility model relates to the internal combustion engine technologies field, especially a kind of cylinder of internal-combustion engine.
Background technique
We know, combustion engine powered is directly to be produced by to-and-fro motion by cylinder sleeve, piston, piston ring, wrist pin and connecting bar and crankshaft, transfer mechanical energy to by heat energy, wherein cylinder sleeve, piston, piston ring are the hearts of internal-combustion engine, contact with high temperature, high-pressure gas, are bearing higher thermal load and mechanical load, produce the friction of high-speed motion during work done again, therefore, the quality of its quality, performance directly has influence on the thermal efficiency, mechanical efficiency, energy consumption and the working life of internal-combustion engine.Prior art as shown in Figure 1, the friction factor of this cylinder is big, the wear rate height is short of power, the easy gum deposit carbon distribution that burns, working life is short.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of cylinder of internal-combustion engine, and this cylinder all is greatly improved, thereby increases the service life for flammability, corrosion resistance, wear-resistant seal, the burning resistive connection colloidality of internal-combustion engine.
The technological scheme that its technical problem that solves the utility model adopts is: be provided with cylinder sleeve, cylinder sleeve is the hollow cylinder matrix, matrix contains rare earth, inner wall surface has a phosphorization membrane, be provided with piston in the cylinder sleeve, piston is a circular base, matrix surface has a phosphorization membrane, and a graphite coating layer is arranged in the skirt section, piston ring, piston ring are arranged is the ring matrix to card on the annular groove of piston, and the upper and lower side of matrix is trapezoidal, its working surface has a ceramal layer, and also has a ceramic film outside the ceramal layer.
The beneficial effects of the utility model are, the explosive motor overall performance is greatly improved, can improve the thermal efficiency of motor, can reduce friction factor between engine gas more than 36%, improve the effective power (can increase) of motor because of the fricting loss power 2%-3% between cylinder, can prolong the working life of internal-combustion engine, can reduce and reduce the oil consumption of fuel oil and machine oil relatively, sufficient combustion, has oxidation catalysis effect preferably (transfer power is more than 30%), simultaneously can improve and reduce the discharging of vehicle exhaust harmful gas CO and HC, help environmental protection and energy-conservation.
