Here's a breakdown of the four strokes in a four-stroke engine:
1. Intake Stroke: The piston moves down the cylinder, creating a vacuum that draws in a mixture of air and fuel through the intake valve.
2. Compression Stroke: The piston moves back up, compressing the air-fuel mixture.
3. Power Stroke: The compressed mixture is ignited by a spark plug, causing an explosion that pushes the piston down.
4. Exhaust Stroke: The piston moves back up, pushing out the burnt gases through the exhaust valve.
The intake stroke is the first and most crucial step in the combustion cycle, as it sets the stage for the subsequent strokes.
