Piston Of Engine

The piston is a component of an internal combustion engine that moves back and forth within a cylinder, creating a reciprocal motion that drives the engine. It is typically cylindrical in shape with a flat top and is made of a high-strength metal such as aluminum alloy or cast iron. The piston is sealed to the cylinder walls with piston rings to prevent the combustion gases from escaping and to ensure efficient transfer of energy from the expanding gases to the connecting rod. The top of the piston is designed with a bowl or dome-shaped depression to help control the combustion process by directing the fuel-air mixture towards the spark plug. The bottom of the piston is connected to the connecting rod, which converts the reciprocating motion of the piston into rotational motion of the crankshaft, which ultimately drives the vehicle or machine.
