Engines are devices that convert various forms of energy, such as chemical, thermal, or electrical energy, into mechanical work. They are essential components of many everyday machines and are used in a wide range of applications, including transportation, power generation, and industrial processes. The engine crankshaft assembly is the main vital component of the engine that generate power as it converts the reciprocating motion of the pistons into rotational motion. This Final Year Project report focuses on the effect of reaction forces on the pin joints as the engine crankshaft goes through its motions and the position, velocity, and acceleration of the piston block over time. The engine crankshaft assembly was modelled using Solidworks and imported over to Ansys Workbench where rigid dynamic analysis was performed. It was observed that the force reactions on the pin joins fluctuates over time according to the crank angle where it the highest at the top and lowest at the bottom of the cycle
