What are the four strokes of a 4-Stroke engine cycle?

The four strokes of a 4-stroke engine cycle are Intake, Compression, Power, and Exhaust. The correct choice outlines these processes effectively.

In the first stroke, the Intake stroke, the engine draws in a mixture of air and fuel as the piston moves down the cylinder. This is crucial as it prepares the engine for the combustion process that follows.

During the second stroke, known as the Compression stroke, the piston moves back up the cylinder, compressing the air-fuel mixture. This compression is vital because it increases the mixture's temperature and pressure, making it more susceptible to ignition.

The third stroke is the Power stroke, where the compressed mixture is ignited. The explosion that results pushes the piston down, creating the power that propels the engine.

Finally, in the Exhaust stroke, the piston moves back up to expel the burnt gases from the combustion process, clearing the cylinder for the next cycle.

These strokes are critical to the engine's operation, and understanding them provides insight into how internal combustion engines function.
