For most small engines (scooters, chainsaws, ...) we use a 2-Stroke Engine.

The 4-Stroke Engine
If you have never seen a 4-Stroke engine before, watch this 8-minute video. It's okay if it doesn't make a lot of sense now.

Now Test Yourself (with a partner)
The video below has no talking and only music.

Be sure to watch at 35 seconds when the colours help you see where combustion is happening.
(This coloured animation helps to show that combustion is only happening once at any given time.)
