From Wikipedia, the free encyclopedia
Animated Engine

An excelent animation of an internal combustion engine, which I discovered accidentally while working on improving a different page. I think this is simply awesome. This originated on the commons.

The entire process illistrated here is explained in words in the article Four-stroke cycle. This should make the desccription of the animation easier. TomStar81 19:53, 11 February 2006 (UTC)[reply]
Uh, and it is also available as an animation! Image:FourStrokeCycle.mpg --Dschwen 17:25, 12 February 2006 (UTC)[reply]

Promoted Image:4-Stroke-Engine.gif: there are exactly twice as many supporters as opposers, which is what I tend to use as my guideline. This was a very close result. Raven4x4x 07:53, 25 February 2006 (UTC)[reply]

  • Comment: Hi - I am UtzOnBike, the creator of this animation. Thanks to all supporters. But here some explanations: 1. This animation was done for the german wikipedia, where it is part of an explanation in text. 2. Of course, some arrows would help - but I do not like arrows in my animations. 3. This animation was done with Autodesk Inventor, a CAD programm. So it is all 3D, but the graphic is not optimized for animations (-> alising). 3. The compression is definitely not infinite! But in pixels, it looks like. 4. The spark itselfes is blue - but looks different (a thin line). 5. There are pistons in a lot of shapes. Some are flat on top, some are roof-shaped (as shown here), some have other shapes. It depends on valve angle, compression, position of spark plug, ... Thanks to all!
