Analysis of Connecting Rod for Weight Reduction in Case of a CI Engine

Abstract— internal combustion engine is one of the best and reliable sources of power generation. It is widely used in domestic and industrial transportation. Every vehicle has internal combustion engine and every IC engine has connecting rod. The main objective of this study was to suggest weight reduction opportunity for connecting rod by analyzing it with different materials. This study deals with static stress analysis of existing connecting rod and second optimization of rod for weight reduction by experimenting it with two new materials. For this study we selected the medium duty compression ignition engine connecting rod. After obtaining dimensions we developed the 3D model of connecting rod by using CATIA software. By importing 3D model in ANSYS static stress analysis was carried out for both ends of connecting rod. Analysis was done for compressive as well as tensile loading, in results determined von mises stress distribution and deformation of connecting rod also we checked weight of connecting rod. Using same procedure we experimented with three different materials and compared the results.
