INTERNAL COMBUSTION ENGINE

摘要

FIELD: engines and pumps.SUBSTANCE: invention relates to automotive industry. ICE comprises cylinder block, cylinder iron sleeve (1), cylinder iron cover (2), steel gasket (3) in gas joint between sleeve (1) and cover (2) studded together and to cylinder block. Gas joint gasket (3) features rectangular cross-section and is made of material its hardness being 10÷15% lower than that of cylinder sleeve (1) and cylinder cover (2). Taken sizes ensure compression forces in gasket (3) resulted from tightening of aforesaid studs at 15÷20% lower force than gasket material yield point. Cylinder sleeve (1) and cylinder cover (2) gas joint surfaces have extending triangular teeth (8) in width and height making 2÷5% of gas joint gasket (3) width and are located at mid section of said gasket.EFFECT: compensated mutual radial and axial shifts of cylinder sleeve and cover.2 dwg
