How a Car Engine Works: Combustion to Crankshaft
This short shows how a tiny explosion inside an engine makes a car move. Fuel and air mix, a spark plug ignites them, and the blast pushes a piston down so the connecting rod turns the crankshaft, turning up and down motion into rotation. The flywheel then smooths the engine's spin. It is aimed at curious teens and general viewers and shown in the CAD Cutaway 3D style with technical machinery in satin industrial blue.

The brief
This is the brief that made the video. Start from it and change what you like.
Make a vertical (9:16) 3D explainer of about 30 seconds on how a car engine works, for a curious general audience. Open by asking how a tiny explosion inside the engine makes a car move. Show fuel and air mixing and a spark plug igniting them, then the explosion pushing a piston down, the connecting rod turning the crankshaft and up and down motion becoming rotation. End with the crankshaft spinning the flywheel, which smooths the engine's rotation. Use a friendly, confident host speaking at a measured pace and clear technical cutaways of the engine's internal parts.
The script
Ever wondered how a tiny explosion inside your car makes it move? It all starts with combustion. Fuel and air mix inside the engine, and a spark plug ignites them, creating a powerful explosion.
That explosion pushes a piston down. The piston moves a connecting rod, which turns the crankshaft. Basically, it converts up-and-down movement into rotation.
The crankshaft spins the flywheel, which helps smooth out the engine's rotation.
