FIELD: transport machine building.
SUBSTANCE: invention relates to the field of transport machine building and can be used in internal combustion engines. Internal combustion engine comprises gas-distributing mechanism with hydraulic drive, which includes oil line 1 of cylinder head, inlet 2 and outlet 3 camshafts, on bearing neck of which there are radial grooves 6, 7, through which oil is supplied to sliding bearing 8 of neck. During prolonged operation of VVT mechanism in extreme angular positions of distribution shaft, when oil is supplied to one of radial grooves, lubrication of sliding bearing 8 takes place due to supply of oil from additional oil channel 9, connecting sliding bearing with independent oil from VVT oil line, using for this purpose feed line of hydraulic pushers of valve drive 10.
EFFECT: task of the invention is aimed at increasing efficiency of oil supply during prolonged operation of VVT mechanism in extreme angular positions, thus improving reliability of engine operation.
