Description
Technical field
The present invention relates to automotive engine applications, be specifically related to a kind of environment protecting type engine cylinder jacket.
Background technology
Cylinder jacket is a cylindrical component, is placed in the cylinder body opening of body, on be fixed by cylinder head.Piston exists
Its endoporus is reciprocating, has cooling water cooling outside it.The function of cylinder jacket has: 1. collectively form cylinder work with cylinder cap, piston
Make space.2. the cylinder jacket of trunk piston diesel bears side thrust of piston, becomes the helical pitch of reciprocating motion of the pistons.3. by piston
Assembly and the heat of itself pass to cooling water, are allowed to operating temperature suitable.4. the cylinder jacket of two stroke diesel engine is disposed with QI KOU,
Opened and closed by piston, it is achieved distribution.
In cylinder jacket, table is directly acted on by high-temperature high-pressure fuel gas, and with piston ring and piston skirt, high-speed slide occurs all the time
Friction.Appearance contacts with cooling water, produces serious thermal stress, by cooling water corrosion under the bigger temperature difference.The piston side to cylinder sleeve
Thrust not only aggravates table friction in it, and makes it produce bending.When side-thrust changes direction, piston also clashes into cylinder sleeve.Additionally
By bigger installation pretightening force.Gas pressure makes cylinder wall produce tangential stress and radial compressive stress, and at inner surface
Maximum, this stress is all dither stress.Because casing wall internal-external temperature difference produces great thermal stress, at general temperature, make interior table
Face produces compressive stress and cooling surface exists tension.But under extra-high temperature, nearly inner surface metal creep plastic deformation, and cool down
After i.e. form residual tension at inner surface, this can make fatigue of materials with starting, stop the low frequency stress that causes of change.
It is insufficient that existing cylinder jacket also exists fuel oil burning, causes carbon distribution more, and carbon distribution can cause abrasive wear, impact
The service life of internal combustion engine.
Summary of the invention
The present invention is to solve weak point of the prior art, it is provided that a kind of environment protecting type engine cylinder jacket, it is possible to make
Fuel oil burning fully, reduces carbon distribution and reduces 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 a kind of environment protecting type engine cylinder jacket, including
Cylinder liner body, a brace shoulder inner hole part for described cylinder liner body is equipped with wearing ring, wearing ring cylindrical and described cylinder jacket
Body is matched in clearance；The upper surface of wearing ring exceeds a brace shoulder upper surface and forms cylinder jacket boss, the upper surface of wearing ring
Match with cylinder cap end face；Wearing ring exceeds cylindrical position and the head gasket inner hole of a brace shoulder upper surface；Wearing ring interior
Hole is provided with reticulate pattern, the texture of this reticulate pattern helically stricture of vagina 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, wear-resistant
Ring diameter of bore is than described little 0.2mm～1mm of cylinder liner body diameter of bore.
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 invention has the beneficial effects as follows:
The environment protecting type engine cylinder jacket of the present invention is by being assemblied in the wearing ring of a brace shoulder inner hole part and matched cylinder
Set body combines wearing ring and the combination of matched cylinder liner body being assemblied in a brace shoulder inner hole part, outside wearing ring
Circle is that small-gap suture coordinates with cylinder liner body, it is possible to make fuel oil burning fully, reduces carbon distribution and reduces the mill caused due to carbon distribution
Grain abrasion, extends the service life of internal combustion engine.
The above of wearing ring exceeds 1.12mm to 1.30mm above cylinder jacket support shoulders, replaces the boss of cylinder jacket, end face
Coordinate with cylinder cap end face；The outside diameter of wearing ring is 119mm to 119.25mm, makes cylindrical and head gasket inner hole；Wear-resistant
The height of ring is 8.5mm to 10mm；Wearing ring diameter of bore is 113mm-113.8mm, and 0.2mm less than cylinder cover inner hole diameter is extremely
1mm；The inner bore chamfering position of wearing ring requires to retain acute angle；The material selection common grey iron material of wearing ring；Wearing ring
Surfaces externally and internally is once got on the bus by numerical control lathe and is processed, and not only ensure that the axiality of inside and outside circle but also ensure endoporus texture helically stricture of vagina
Shape.Cylinder cover inner hole reticulate pattern is: Rpk<0.25um, Rk<0.5um, Rvk:1.5-2.5um, Rvk/Rk>2.Wearing ring endoporus reticulate pattern
Using thin plateau honing cross hatches, groove is many and shallow, can either ensure that endoporus lubrication needs and is avoided that Excess lubricating oil participates in combustion
Burn, reduce the discharge of oxynitride.Due to boring ratio cylinder sleeve bore diameter in the wearing ring of cylinder jacket support shoulders mounted inside
Little, it is possible to the lubricating oil hindering piston ring unnecessary time up participates in burning, can hinder again and under high-temperature fuel gas, exercise lubricating oil evil
Change rotten.When the carbon distribution of wear-resistant annular groove inwall reaches certain thickness, it is possible to when utilizing piston crown up, unnecessary carbon distribution is blown
Go out cylinder jacket, it is possible to be prevented effectively from abrasive wear, improve cylinder jacket service life.
