CYLINDER BLOCK HEAD FOR INTERNAL COMBUSTION ENGINE (EMBODIMENTS) Russian patent published in 2019 - IPC F02F1/26 

FIELD: internal combustion engines.

SUBSTANCE: invention can be used in the internal combustion engines. Cylinder head (100) for internal combustion engine comprises internal structural metal element (102) having first plate (104) forming coupling surface (106) of cylinder block head and forming row of plate ceiling (108) of cylinders. Inner structural element (102) comprises posts (110) for bolts of the cylinder block head passing from first plate (104), guides (112) of the outlet valves connected to first plate (104) by the first support bars (114), inlet valve guides (116) are connected to first plate (104) by second support bars (118), and second plate (120) configured to mount outlet manifold and extending at an angle to first plate (104). Unit head (100) comprises outer composite element (150) supported by inner structural element (102) surrounding it and forming cylinder block head housing. Cylinder head housing comprises wall (154) of inlet side, first and second end walls (156) and top wall (152) opposite to interface surface (106). External composite element (150) forms a cooling jacket, inlets and outlets. External composite element (150) includes posts for cylinder head bolts and guides of inlet and outlet valves of internal structural element. Flow channels of cooling jacket formed by external composite element (150) are lined with metal walls contacting with composite material of external composite element (150) and enclosed therein. Invention covers also version of cylinder block.

EFFECT: technical result consists in improvement of accuracy of position control, as well as improved control of physical shape of flow channels for heat transfer.
