Objectives: This paper aims at studying force distribution characteristics and load with standing capability of a remodelled IC engine piston connecting rod arrangement where the conventional single piston single connecting rod arrangement is replaced by linking two pistons with a single connecting rod. Methods\Statistical Analysis: 3D Modelling of the arrangement is carried out using Solid works while force analysis of the model is done using ANSYS workbench. Parallel twin cylinder 4 stroke petrol engine is utilized as reference for creating the model and analysis purpose. Findings: The results gives the theoretical evidence that there can be a considerable reduction in engine weight and complexity with this new arrangement with stress, deformation and strain values lying within the boundary. Applications\Improvements: This arrangement gives extra room for lubricants thereby indeed indirectly increasing performance characteristics.
