The
Piston is a crucial component of an
Engine Assembly. It plays a vital role in the combustion process, converting the energy released from the fuel into mechanical motion.
The piston is a cylindrical-shaped metal piece that fits snugly within the engine cylinder. It moves up and down within the cylinder bore, creating a sealed chamber where combustion occurs. The top of the piston, known as the crown, is designed to withstand high temperatures and pressures generated during the combustion process.
The piston is connected to the
Connecting Rod, which in turn is connected to the crankshaft. As the piston moves downward during the intake stroke, it creates a vacuum that draws in the air-fuel mixture into the combustion chamber. During the compression stroke, the piston moves upward, compressing the mixture to increase its pressure and temperature.
When the
Spark plug ignites the compressed mixture, a rapid expansion of gases occurs, pushing the piston downward with great force. This is known as the power stroke, where the energy of the combustion is transferred to the piston. Finally, during the exhaust stroke, the piston moves upward again, expelling the burned gases out of the engine through the exhaust
Valve.
To ensure efficient operation, the piston must be properly lubricated to reduce friction and wear. It is typically fitted with piston rings that seal the combustion chamber and prevent the escape of gases. These rings also help to maintain proper oil distribution on the cylinder walls.
In conclusion, the piston is an essential component of an engine assembly, responsible for converting the energy of combustion into mechanical power. Its design and function are crucial for the overall performance and efficiency of the engine.
