Description
Technical field
The utility model is related to automotive engine applications more particularly to a kind of engine cylinder rings with double limiting layers and
Engine.
Background technology
With the rapid development of auto industry, as engine important spare part --- the technology of head gasket is also very fast
Development converts from compound head gasket to Metallic cylinder head gasket.Its conversion rate is fast, and scale is big, and range is wide, has surpassed
Go out the expectation of people.Engine flare pressure is higher and higher, and the sealing problem of the high-temperature high-pressure fuel gas of in-cylinder combustion is increasingly serious.
Although the raising of cylinder bolt pretightning force can improve the contact of head gasket sealed muscle and cylinder block and head, but can not protect
Demonstrate,prove the continuous uniform of contact around cylinder holes.The raising of explosion pressure, the longitudinal deformation amount of cylinder cap can also increase therewith simultaneously.
The deformation of cylinder cap can not only influence the reliability of itself, it is often more important that can cause it is unreal for the compression of head gasket, so as to
Cause seal failure.
The effect of head gasket is to ensure the reliable sealing of gas, oil, water in internal combustion engine normal operation.Its working mechanism
It is that the axial force to be formed is tightened by cylinder bolt, makes cylinder cap compression cylinder pad.The sealed muscle arranged on head gasket is by cylinder
During the compression of lid, generate and form contact between flexible deformation, with cylinder block and head, so as to fulfill to media such as gas, oil, water
Reliable sealing.In engine working process, particularly around cylinder holes, to realize that head gasket reliably seals, contact is necessary
Reach certain numerical value, and contact answers uniformly continuous everywhere in sealed muscle.Because gaseous-pressure is higher in cylinder-bore, cylinder-bore week
Contact between the sealed muscle and cylinder block and head that enclose is larger, so surrounding sealed muscle elastic deformation amount is relatively large.And
By high temperature action in cylinder, sealed muscle is also easy to produce plastic deformation, so as to lose sealability.Traditional head gasket service life
Short, leakproofness reduces after a period of use, causes three leakages problem, cannot be reused after head gasket dismounting, maintenance cost is high.
Further, since the exhaust manifold cylinder head of engine, the rigidity of structure of deckless engine block are insufficient and high supercharging pressure level is pressurized
Gas sealing can be all brought when engine leads to the problem of extra-high.
Therefore, it is necessary to head gasket of the prior art is improved, it is close so as to solve the combustion gas of engine cylinder ring
Envelope problem.
