Technological cylinder gasket for machining of cylinder holes of cylinder body of engine

Abstract

The invention discloses a technological cylinder gasket for machining of cylinder holes of a cylinder body of an engine. The technological cylinder gasket for machining of the cylinder holes of the cylinder body of the engine comprises an upper cylinder gasket plane layer and a lower cylinder gasket plane layer, wherein the upper cylinder gasket plane layer and the lower cylinder gasket plane layer are stacked vertically, and are fixed integrally through rivets, air cylinder holes, installing holes and bolt through holes are formed in the technological cylinder gasket, and a thickened layer is arranged between the upper cylinder gasket plane layer and the lower cylinder gasket plane layer, and is arranged at the periphery of the air cylinder holes. According to the technological cylinder gasket for machining of the cylinder holes of the cylinder body of the engine, rigid contact between the cylinder body and a cylinder head is eliminated when the cylinder holes are machined, the situation that when assembly is carried out, deformation of the cylinder holes is caused due to tightening force of connecting bolts for connection between the cylinder body and the cylinder head is borne by the cylinder holes is really simulated, the machined cylinder holes can have higher roundness in the assembly state, abrasion between piston rings and the cylinder holes is reduced, engine oil consumption is reduced, performance of the engine is improved, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to a technical cylinder head gasket for processing cylinder holes of engine cylinder blocks. Background technique [0002] The cylinder gasket is a deformed part, which is located between the cylinder block and the cylinder head. It is affected by the extrusion force and plays an important role in the sealing between the cylinder block and the cylinder head. It has a great influence on the assembly accuracy of the engine. At present, the machining of the cylinder bore of the existing engine cylinder block is carried out under the condition that the cylinder bore of the cylinder block is not stressed. After the engine is assembled, the cylinder bore of the cylinder block is deformed under the action of the bolt tightening force, and the roundness of the cylinder bore If it is poor, the wear between the piston ring and the cylinder hole will increase, and the oil consumption will increase, which will affect the performance and life ...
