【 摘 要 】

In this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as we produce electricity and heat by burning fossil fuels it is pointless to try to replace all thermal engines with electric motors, as the loss of energy and pollution will be even larger. However, thermal engines should be continuously improved to reduce fuel consumption. A great loss of power is attributed to heat engines with internal combustion and distribution mechanism, a reason for the improvement of the functionality of this mechanism. The dynamic synthesis of this type of distribution mechanism can be made shortly, by the Cartesian coordinates, but to determine these coordinates we need trigonometric parameters of the mechanism. Dynamics and forces of this distribution mechanism are presented as well. One introduces the dynamic coefficient D.
