A Comparative Design and Analysis of Conventional and Variable Connecting Rod of Engines

Abstract

Geometric compression is one of the primary design parameters for internal combustion engines. It is determined by the maximum volume ratio of the combustion chamber between the bottom dead center (BDC) and the minimum size of the combustion chamber in the position of the top dead center (TDC). In this study, a new motor was designed with a variable compression ratio (VCR) to enhance its performance. The comparison between the conventional engine and the turbo variable compression was analyzed using SolidWorks software. The results showed the advantages of VCR due to the change in performance according to changes in the required torque by varying the connecting rod stroke.
