How a Four-Stroke Engine Powers Your Ride!

Scene 1: Engine side-view – transparent overlay showing inner mechanics
The four-stroke engine – a marvel of mechanical engineering.
It powers most of the vehicles we drive today.
But how does it work?
Let’s break it down, stroke by stroke.

Scene 2: Piston inside cylinder – Intake stroke in motion
Stroke 1: The Intake Stroke
The piston moves downward.
The intake valve opens.
A mixture of air and fuel is drawn into the combustion chamber.
Think of it as the engine breathing in.

Scene 3: Compression – valves closed – piston rising
Stroke 2: The Compression Stroke
The piston rises again, compressing the air-fuel mixture.
This increases pressure and temperature – preparing for ignition.
It’s like cocking a spring – ready to release power.

Scene 4: Spark ignition – explosion – piston pushed down
Stroke 3: The Power Stroke
The spark plug fires.
BOOM – a small explosion pushes the piston down with force.
This is where the engine generates power.
It converts fuel into kinetic energy.

Scene 5: Piston rising – exhaust valve opens – fumes escape
Stroke 4: The Exhaust Stroke
The piston rises one last time.
The exhaust valve opens.
Burned gases are expelled from the chamber.
The engine breathes out.

Scene 6: Crankshaft rotating, showing smooth motion
These four strokes – intake, compression, power, and exhaust – happen in rapid succession.
Connected to a crankshaft, they transform linear motion into rotational force.
This is what spins your wheels.

Scene 7: Wide shot – engine running, car moving
From raw fuel to motion on the road – this is the magic of internal combustion.
Simple. Reliable. Powerful.
The four-stroke engine.
A century-old technology… still roaring today.
