What are the four strokes of a four-stroke engine cycle?

The four strokes of a four-stroke engine cycle are Intake, Compression, Power, and Exhaust. This cycle is fundamental to the operation of an internal combustion engine, where each stroke corresponds to a specific phase in the process of converting fuel into mechanical energy.

During the Intake stroke, the engine's intake valve opens, allowing the air-fuel mixture to enter the combustion chamber as the piston moves down. This stroke creates a vacuum that draws in the mixture, setting the stage for combustion.

In the Compression stroke, the piston moves back up, compressing the air-fuel mixture. This compression is crucial because it raises the temperature and pressure of the mixture, making it more volatile and ready for combustion.

The Power stroke, also known as the ignition stroke, occurs when the spark plug ignites the compressed air-fuel mixture, causing a rapid expansion of gases. This explosion pushes the piston down with significant force, generating power to turn the crankshaft and ultimately power the vehicle.

Finally, during the Exhaust stroke, the exhaust valve opens, and the piston moves back up again to expel the burnt gases out of the cylinder. Properly completing this stroke is essential for maintaining the efficiency of the engine and making room for the next intake of fresh air-f
