FIELD: machine building.
SUBSTANCE: present invention relates to a motor comprising a cam shaft with several cams configured to drive one or more engine valves, as well as an auxiliary motor device, and in particular, but not exclusively, to a motor comprising a cam shaft. Engine comprises cam shaft (101) made with possibility of connection with auxiliary device made with possibility of its driving from cam shaft (101), wherein cam shaft (101) comprises: several valve cams (105), each of which is configured to drive corresponding inlet valve (111) or exhaust valve (111) of the engine. At that, angular orientations of valve cams (105) relative to rotation axis of cam shaft (101) are determined by requirements for operation of valves (111); and cam (107) of auxiliary device, configured to drive control element (113) of auxiliary device by means of one or more cams; wherein cam (107) of auxiliary device has a certain angular orientation relative to axis of rotation of cam shaft (101), and control element (113) has a certain angular orientation relative to axis of rotation of cam shaft (101), when auxiliary device is connected to engine, wherein angular orientation of at least one of components: cam (107) of auxiliary device and/or control element (113) of auxiliary device is selected taking into account angular orientation of valve cams (105) so that each act of drive of auxiliary device takes place in interval between two sequential acts of valve drive.
EFFECT: technical result consists in minimizing vibrations of resistive torque transmitted to main drive and/or to any other device connected to cam shaft.
