【 摘 要 】

Thispaper presents an algorithm for setting the dynamic parameters of the classicmain mechanism of the internal combustion engines. One presents the dynamic,original, machine motion equations. The equation of motion of the machine thatgenerates angular speed of the shaft (which varies with position and rotationspeed) is deduced by conservation kinetic energy of the machine. An additionalvariation of angular speed is added by multiplying by the coefficient dynamic(generated by the forces out of mechanism). Kinetic energy conservation showsangular speed variation (from the main shaft) with inertial masses, while thedynamic coefficient introduces the variation of w with forces acting in the mechanism. Derivingthe first equation of motion of the machine it obtains the second equation ofmotion dynamics. From the second equation of motion of the machine onedetermines the angular acceleration of the motor shaft. It shows thedistribution of the forces (on the main mechanism of the engine) to theinternal combustion heat engines. Dynamic, the velocities can be distributed inthe same way as forces. Practically, in the dynamic regimes, the velocitieshave the same timing as the forces. The method is applied separately for twodistinct situations: When the engine is working on a compressor and into themotor system. For the two separate cases, two independent formulas are obtainedfor the engine dynamic cinematic (forces speeds). Calculations should be madefor an engine with a single cylinder.
