ABSTRACT -Crank shaft is a long shaft that is commonly used for multi cylinder engine to connect various cranks. The firing of this multi cylinder engine should be in particular order. In general, for a 4-stroke I.C engine the firing order will be 1-4-3-2 This is because of balancing. If this order is not followed, it will lead to the stress development in one side of the crankshaft and it will eventually bend. To avoid this firing order is necessary. One of the most critically loaded components in the engine is the crankshaft, as it experiences cyclic loads in the form of bending and torsion during its service life. Its disappointment will bring about genuine harm to the engine, so its unwavering quality check must be performed. The aim of this project is to design a two- wheeler four stroke petrol engine crankshaft using SOLIDWORKS and perform structural analysis for three different materials using ANSYS.
