Abstract


This paper presents an algorithm for setting the dynamic parameters of the classical distribution mechanism of the internal combustion engines. One presents the dynamic, original, machine motion equations. The equation of motion of the machine that generates angular speed of the camshaft (which varies with position and rotation speed) is deduced by conservation kinetic energy of the machine. An additional variation of angular speed is added by multiplying by the coefficient dynamic D (generated by the forces out of mechanism). Kinetic energy conservation shows angular speed variation (from the cam shaft) with inertial masses, while the dynamic coefficient introduces the variation of  with forces acting in the mechanism. Deriving the first equation of motion of the machine we obtain the second equation of motion dynamics. From the second equation of motion of the machine we determine the angular acceleration of the camshaft. It shows the distribution of the forces on the cam shaft mechanism to the internal combustion heat engines. Dynamic, the velocities can be distributed in the same way as forces. Practically, in the dynamic regimes, the velocities have the same timing as the forces. Calculations should be made for an engine with a single cylinder
