Description
Technical field
The present invention relates to automotive engine applications, be specifically related to the environment-friendly type cylinder jacket of a kind of anti-cavitation pitting.
Background technology
Cylinder jacket is a cylindrical component, is placed in the cylinder body opening of body, on be fixed by cylinder head.Piston hole within it is reciprocating, has cooling water cooling outside it.The function of cylinder jacket has: 1. collectively form cylinder operation space with cylinder cap, piston.2. the cylinder jacket of trunk piston diesel bears side thrust of piston, becomes the helical pitch of reciprocating motion of the pistons.3. piston component and the heat of itself are passed to cooling water, be allowed to operating temperature suitable.4. the cylinder jacket of two stroke diesel engine is disposed with gas port, piston open and close, it is achieved distribution.
Cylinder sleeve waterway wall plays within the engine and contacts thus to because of gasoline or the diesel oil overheated important function cooled down produced by compression knock in cylinder sleeve with its outer surface by engine cooling water.The design of existing cylinder jacket water channel wall thickness is relatively thin, and under our country's road actual conditions, the frequent high load capacity of engine works, and cavitation erosion often occurs in air cylinder sleeve of engine waterway wall.
Cavitation pitting is a kind of special shape of corrosion, it is physical damage and the product of chemical depletion combination, cast iron cylinder cover outer wall in engine-cooling system often occurs, engine combustion indoor ignition, piston " bounces " cylinder sleeve with bigger power, cylinder sleeve high vibration, when in time leaving the vibration of coolant direction, a low-pressure area can be formed outside cylinder sleeve and between coolant, in low-pressure area, coolant gasification forms bubble, when in time vibrating near coolant direction, low pressure bubble is stressed upon outer wall of cylinder jachet and fierce blast occurs, pressure is up to 60000ps(about 420MPa).Continuous print vibration makes bubble explode continuously, cylinder jacket outer wall materials fatigue comes off, the outer wall of cylinder jachet that goes down for a long time produces many apertures, the bubble produced subsequently is easily detained at these apertures, then bubble continues to rupture, making original hole constantly imposing manner expand, the penetrated cylinder sleeve having, cylinder jacket outer surface forms cellular cavitation pitting.
Burning insufficient additionally, existing cylinder jacket there is also fuel oil, carbon distribution is more, and carbon distribution can cause abrasive wear, affects the service life of internal combustion engine.
Summary of the invention
The present invention is to solve weak point of the prior art, the environment-friendly type cylinder jacket of a kind of anti-cavitation pitting is provided, add cylinder jacket integral rigidity, vibration when reducing cylinder jacket work, to realize anti-cavitation pitting, two or seven its can make fuel oil burning fully, reduce carbon distribution and reduce the abrasive wear caused due to carbon distribution, extending the service life of internal combustion engine.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that the environment-friendly type cylinder jacket of a kind of anti-cavitation pitting, including cylinder liner body, it is provided with waterway wall on the waterway wall of described cylinder liner body and strengthens structure, waterway wall strengthens the enhancing set that structure includes arranging around waterway wall outer peripheral face, the wall of the inner peripheral surface and waterway wall that strengthen set is fixed and is connected, and the outer peripheral face strengthening set is set to the conical surface, and this conical surface seamlessly transits with the wall junction of waterway wall；Being provided with packing ring at a brace shoulder lower surface of described cylinder liner body, gasket sleeve is located on described cylinder liner body.
A brace shoulder inner hole part for described cylinder liner body is equipped with wearing ring, and wearing ring cylindrical and described cylinder liner body are matched in clearance；The upper surface of wearing ring exceeds a brace shoulder upper surface and forms cylinder jacket boss, matches with cylinder cap end face in the upper surface of wearing ring；Wearing ring exceeds cylindrical position and the head gasket inner hole of a brace shoulder upper surface；The endoporus of wearing ring is provided with reticulate pattern, the texture of this reticulate pattern helically line shape.
The two ends up and down of the endoporus of described wearing ring are provided with chamfering.
The chamfering at the two ends up and down of the endoporus of described wearing ring is identical, and is acute angle.
The upper surface of described wearing ring exceeds brace shoulder upper surface 1.12mm～1.30mm；The outside diameter of wearing ring is 119mm～119.25mm；The height of wearing ring is 8.5mm～10mm；Wearing ring diameter of bore is 113mm～113.8mm, and wearing ring diameter of bore is than described little 0.2mm～1mm of cylinder liner body diameter of bore.
The described conical surface upper end towards described cylinder liner body strengthening set.
Described packing ring selects copper packing.
Described wearing ring is made up of gray cast iron material.
It is machined with logo slot at the skirt section cylindrical of described cylinder liner body.
The described axial length strengthening set is 40mm, and the axial width of packing ring is 0.813mm.
The invention has the beneficial effects as follows:
1, the environment-friendly type cylinder jacket of the anti-cavitation pitting of the present invention strengthens design by waterway wall and cylinder jacket support shoulders lower surface increases by two kinds of structures of copper packing and designs, add cylinder jacket integral rigidity, vibration when reducing cylinder jacket work, to realize anti-cavitation pitting, and above two design is all to realize on the basis of not changing engine design.
2, it is provided with waterway wall on the waterway wall of described cylinder liner body and strengthens structure, waterway wall strengthens the enhancing set that structure includes arranging around waterway wall outer peripheral face, the wall of the inner peripheral surface and waterway wall that strengthen set is fixed and is connected, the outer peripheral face strengthening set is set to the conical surface, this conical surface seamlessly transits with the wall junction of waterway wall, this waterway wall strengthens design and occurs one conical surface of position design of cavitation pitting at cylinder jacket waterway wall, so can increase the intensity at this position, be hit when reducing cylinder jacket work generation Oscillation Amplitude, coolant current can be made again to change, reduce the bump of position, water hole current and increase cooling effect.
3, it is provided with packing ring at a brace shoulder lower surface of described cylinder liner body, gasket sleeve is located on described cylinder liner body, packing ring selects copper packing, by designing a copper packing in cylinder jacket support shoulders lower surface, utilize the good ductility of copper product, reduce the Oscillation Amplitude in the air cylinder sleeve of engine course of work.
