FIELD: engines and pumps. ^ SUBSTANCE: invention is related to manufacture of internal combustion engines. Internal combustion engine comprises tray, crankshaft with cheeks, one pair of connecting rods, head with inlet and outlet valves, spark plug or nozzle in diesel installed inside tray. Connecting rods are connected directly with rod journal of crankshaft or one of connecting rods called as towed, is hingedly connected to the other main connecting rod connected to rod journal. One rocker arm having cinematic connection with head is hingedly connected to each connecting rod. Tray comprises U - shaped plate installed inside between crankshaft cheeks, opposite to head, symmetrically relative to vertical plane passing through axis of crankshaft rotation. Width of U - shaped plate is equal to distance between crankshaft cheeks. Central part of U - shaped plate is arranged by radius, center of which coincides with axis of crankshaft rotation, and its value is equal to radius of rotation of radial seals of crankshaft heads of connecting rods relative to axis of crankshaft rotation. Tray comprises inlet channel on top on the right side from head, and this channel connects air cleaner with cavity for working cycle strokes and suction cavity of fan. Outlet channel is installed on the left side of head, and connects injection cavity of fan to atmosphere. Above head bypass channel is installed with relief valve, which connects outlet channel with inlet channel. ^ EFFECT: increased efficiency of engine cooling. ^ 4 dwg |
