Having escaped the shadow of the global energy crisis by implementing nuclear fission, wind, solar, bioenergy, but also by producing and extracting (deep) gases capable of providing us with planetary reserves for two more. Or at least three thousand years, we have started to relax more energetically, but due to the huge pollution produced by cars, the rules of their increasingly drastic operation are constantly imposed, the cars always being equipped with new devices capable of reducing the level of the harm produced by them. The work presents a few original elements about the dynamic and kinematics of piston mechanism, used like motor mechanism from OTTO engines. One presents an original method to determine the efficiency of the piston mechanism used like a motor mechanism. With the relations of motor efficiency and piston acceleration on optimizing the Otto mechanism, which is the principal mechanism from internal-combustion engines. This is the way to diminish the acceleration of the piston and to maximize the efficiency of the motor mechanism. One optimizes the constructive parameters: e, r, l, having in view the rotation speed of drive shaft, n.
