Basic Concepts of Engine Piston Assemblies

Engine piston assemblies are fundamental to the operation of internal combustion engines. They function by converting the energy from fuel combustion into mechanical energy, which powers the vehicle. The piston moves up and down within the cylinder, driven by the pressure from the combustion process. This motion is transferred through the connecting rod to the crankshaft, which converts the linear motion of the piston into rotational motion to drive the wheels. The piston assembly interacts with other engine components, such as the cylinder walls, rings, and bearings, to ensure smooth and efficient operation ¹.
