FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Distributing shaft (103) for engine is driven by synchronous drive (101) connected with engine crankshaft (107). Synchronous drive (101) comprises one or several non-circular drive elements (105), (109) configured to compensate for torque fluctuations. Distributing shaft (103) comprises cam ledges (115), each of which is configured to activate valve of corresponding engine cylinder. Phase angle of each of cam ledges (115) and/or the profile of each of cam ledges (115) is independently selected to compensate for variation of the profile of the lifting height of the respective valves caused by one or more non-circular drive elements (105), (109). There is disclosed a motor comprising a camshaft.
EFFECT: technical result consists in reduction of torque load oscillations transfer occurring on distributing and crankshafts to drive devices connected with synchronous drive.
