Cylinder block & have spent - - - - - - Two kinds of jacket)

Set of two types of cylinder cylinder block cylinder boring directly on the cylinder block is called the integral cylinder, one-piece cylinder strength and stiffness are good, can bear larger load, the cylinder on the material demand is high, the high cost. If the cylinder manufacture into separate cylindrical parts ( The jacket) And then put into the cylinder body. So, cylinder liner abrasion resistant materials, high quality cylinder block price lower general materials are available, and thus reduces the manufacturing cost. At the same time, can be removed from the cylinder block, cylinder liner and thus facilitate the repair and replacement, and can greatly prolong the service life of cylinder block. Cylinder liner with dry and wet cylinder liner cylinder the characteristics of two kinds of dry cylinder liner is set into the cylinder block, cylinder its outer wall does not directly contact with cooling water, and direct contact and wall of the cylinder block, with thin wall thickness and is usually to mm. It has the advantages of integral cylinder block, strength and stiffness are better, but the processing is more complex, interior and exterior require finishing, dismantling inconvenient, poor heat dissipation. The characteristic of wet cylinder liner is set into the cylinder block, cylinder wall outside its direct contact with the cooling water, only in the upper and lower cylinder each have a ring belt and contact cylinder block, wall thickness is commonly - mm. Its good heat dissipation, cooling uniformity, easy processing, usually need only inside surface finishing, and do not need machining the outer surface of the contact with water, tear open outfit is convenient, but the disadvantage is that good strength and stiffness than dry cylinder liner, and prone to leakage phenomenon. Should take some leakage prevention measures.
