How 4-Stroke Spark Ignition (SI) Engine Operates?

The 4-stroke Spark Ignition (SI) engine operates through a cycle of four distinct piston movements (strokes) to convert fuel into mechanical energy:

1. Intake (Suck): Piston goes down, pulling in fuel and air.
2. Compression (Squeeze): Piston goes up, crushing the mixture.
3. Power (Bang): Spark plug fires, explosion forces the piston down (creates power).
4. Exhaust (Blow): Piston goes up, pushing out waste gases.
The Loop: Suck \rightarrow Squeeze \rightarrow Bang \rightarrow Blow.
