In this work, Calculations and design of connecting rod of IC engine is performed in innovative way. Calculation point of view, Con rod is the utmost critical component of IC Engine as it is the part which translates reciprocating forces into rotary forces and thus creates unbalance in engine. From the functionality point of view, connecting rod must have the higher inertia at the lowest weight. Different forces acting on con rod are: - Peak combustion pressure, inertia force of reciprocating masses, Weight of Reciprocating parts and frictional forces due to cylinder wall thrust. It experiences complex forces of compression and tensile in cyclic manner, which repeats after each 720 (in case of 4 stroke) or 360 (in case of 2 stroke) phase of degree. Hence, the design calculations are analyzed for the axial compressive as well as axial tensile loads considering the fatigue strength of con rod. This literature computes the required size and strength in the critical areas of failure. The calculation methodology is also cross confirmed by applying it on existing three state of the art con rods of different categories of engine, like 2 wheeler petrol engine, 4 Cyl diesel engine and Heavy Vehicle Engine.
