Abstract

The invention belongs to the technical field of engines, and particularly relates to a dry type air cylinder sleeve and an engine. The dry type air cylinder sleeve comprises a body and a deformation structure, wherein a cylindrical hole is formed in the body and matched with a piston of the engine; and the deformation structure is formed on the outer wall of the body and arranged to be matched with a deformed cylinder body of the engine. According to the dry type air cylinder sleeve, the deformation structure is machined on the outer wall of the air cylinder sleeve so as to adapt to deformation of the cylinder body of the engine, when the engine deforms, the deformation structure can offset part of deformation of the cylinder body, the inner wall of the air cylinder sleeve is prevented from deforming, the cylindricity in the body is guaranteed, and the problems of piston ring abrasion, cylinder scuffing and the like are avoided.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a dry cylinder liner and an engine. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] In the prior art, cylinder liners are mainly divided into wet cylinder liners and dry cylinder liners. [0004] For dry cylinder liners, in order to enhance heat transfer as much as possible, the wall thickness of the cylinder liner is getting smaller and smaller, and has been developed to 1.5mm or even 1mm at present. For this type of cylinder liner, although it is good for heat transfer when it is matched with the cylinder block, because the wall thickness is too thin, the cylinder liner and the cylinder bore of the cylinder block are interference fit. The hole will be deformed, and the cylinder head and the cylinder block are connected by cylinder head bolts. During assembl...
