INTERNAL COMBUSTION ENGINE (EMBODIMENTS) AND ENGINE CYLINDER HEAD GASKET WITH COOLING JACKET Russian patent published in 2019 - IPC F01P3/02 F02F1/14 F02F1/40 F02F11/00 

FIELD: internal combustion engines.

SUBSTANCE: invention can be used in internal combustion engines with water cooling. Internal combustion engine includes cylinder block (100) defining surface (103) of block plate, first and second cylinders, jacket (130) of block cooling, head (102) of cylinders and head gasket (104). First and second cylinders are located nearby and separated by block jumper (126). Cylinders head (102) comprises cylinder head surface (101), which limits first and second chambers and head cooling jacket (150). First and second chambers are located nearby and separated by head (106) jumper. First chamber and the first cylinder form the first combustion chamber. Second chamber and the second cylinder form the second combustion chamber. Head gasket (104) is located between cylinder block (100) and cylinder head (102). Head gasket (104) has block side and head side. Unit cooling jacket (130) comprises first channel (172) and second channel (174) crossing the block plate surface (103) on the different sides of block jumper (126). First channel (172) is located from the first side of longitudinal axis of block (100) of cylinders. Head cooling jacket (150) comprises the third channel and the fourth channel, which cross the surface of the cylinder head on opposite sides of head jumper (106). Third channel is located from the first side of longitudinal axis of the block of cylinders. Block (126) jumper limits the jumper cooling channel coming from first channel (172) at surface (103) of the block plate to second channel (174) at surface (103) of the block plate. Head gasket (104) is configured to connect upstream first (172) and fourth channels so that coolant can flow from first channel (172) through cooling channel of jumper to fourth channel for cooling of corresponding jumper. Invention discloses an internal combustion engine version and a head gasket for an engine with a cooling jacket.

EFFECT: technical result consists in improvement of cooling of jumper between adjacent cylinders of engine.
