Optimization of the connecting rod length

Abstract

Internal combustion engine is an irreplaceable power unit for vehicles today. In order to design new and improve the existing engines, it is necessary to perform certain calculations. It has been proven that the length of the connecting rod significantly impacts the engine dimensions, as well as the forces that occur in the piston mechanism. In the framework of this study, possibility to reduce the length of the connecting rod, thus reducing weight and dimensions of entire engine, while not increasing deformations and stresses that have influence on the piston mechanism, was analysed in the paper. The basic tool for optimization of the connecting rod was ANSYS software. Application of this software and similar allows rapid production of parts, which enables the producer to be competitive on the market. In addition, it requires less input energy and money, which enables the producers to obtain higher profit.
