Engines

Resources for understanding how engines actually work.

How they work

Animated Engines (Website) — clear, interactive animations of how engines run, from four-stroke to Stirling.

• Four stroke (Interactive) — the Otto cycle, one stroke at a time.
• Wankel (Interactive) — makes the rotary finally click.
• Single Cylinder Stirling (Interactive) — the clearest hot/cold cycle animation.

• How a Car Works (Website) — free illustrated course on the whole car, engine included.
