4 Strokes of an Engine (Four-Stroke Cycle):
1. Intake Stroke
🔹 What happens:
The piston moves downward, and the intake valve opens.
Air and fuel mixture enters the cylinder.

🔹 Purpose:
To fill the engine cylinder with the fuel-air mixture for combustion.

2. Compression Stroke
🔹 What happens:
The piston moves upward while both intake and exhaust valves remain closed.
It compresses the air-fuel mixture into a smaller volume.

🔹 Purpose:
To make the mixture dense and ready for ignition, increasing efficiency.

3. Power Stroke (Combustion Stroke)
🔹 What happens:
The compressed mixture is ignited by a spark plug.
The explosion pushes the piston downward with force.

🔹 Purpose:
This is where energy is produced to move the vehicle.

4. Exhaust Stroke
🔹 What happens:
The piston moves upward again, and the exhaust valve opens.
The burnt gases are expelled out of the cylinder.

🔹 Purpose:
To clear the cylinder of waste gases so a new cycle can begin.

🎯 Quick Memory Trick:
Intake → Compression → Power → Exhaust
(Fill → Squeeze → Boom → Blow out)
