The theoretical basis for calculating combustion engines dates back to the turn of the 19th and 20th centuries. This was, of course, the pre-computing era. Therefore, in order to make calculations possible then, a number of simplifications had to be used. Today there is no such need. It turns out, however, that most "very advanced" computational tools use old theories unchanged in "modern" computing systems. The aim of the work is to present a method for calculating the position, speed and acceleration of a piston in the crank system. Due to the geometrical dependence of the elements of the engine crank system, it is necessary to calculate the value of the element from a very small number. It was practically impossible without the use of computers. Hence, the appropriate dependencies were developed into a power series. Today there is no such need. It has been shown in the measurements of the engine that the analytical calculated piston path practically does not differ from the measured one. The differences are relatively small and are in the speed of the piston and its acceleration achieved in "classical" and analytics method. These differences were found to be due to values in members with twice frequency of the baseline. [ABSTRACT FROM AUTHOR] |
