Cylinder gasket

Cylinder gasket between the cylinder headand cylinder block is also called the cylinder bed. The purpose is to fill the cylinder block and cylinder head between the microscopic pore, guarantee the sealing of the binding surface has good ensuring that cylinder combustion chamber of the seal leak and water leak. With the continuous strengthening of internal combustion engine, thermal load and mechanical load are increased, cylinder gasket sealing becomes more and more important. The requirements of the structure and material is: in under the condition of high temperature and high pressure and high corrosion gas has enough strength, heat resistance; A lot of damage or deterioration, corrosion resistance; Have certain elasticity, can compensate joint surface roughness, to ensure that the seal; Long service life.

At present there are several applications more cylinder pad:
Is a kind of metal - asbestos cylinder pad. This kind of asbestos between metal wire or metal scrap, and coated with copper or steel sheet. This GangDian thickness is 1.2 ~ 2 mm with good flexibility and heat resistance, can use repeatedly, but strength is poorer, thickness and quality is uneven.
Another kind is made with solid metal. This mat is multi-purpose in strengthening engine, use it more in the car. The gasket to seal around the cylinder hole and hole and oil hole punching out a certain height of rib, using the elastic deformation of pique to seal.
In addition to using center with preparation of wire mesh or perforated plates on both sides of the frame with asbestos and rubber binder pressed into the cylinder head gasket.
