Animated scheme of a four stroke internal combustion engine, Otto principle.
[edit] Detailed Description
- Fuel and oxygen are injected
- Fuel and oxygen are compressed and ignited
- Fuel combusts and piston is pushed downwards
- Exhaust is removed
[edit] Warnings & Comments
Warning: This animation is not completely accurate. There should be some space left when the piston is at its highest position. The current animation suggests infinite compression.
Comment: This is a 2D projection of a 3D model. The little space went lost in the pixels of the outlines. And a 2D projection is not able to show the space around the "roof" of the piston. (UtzOnBike) --85.182.123.226 20:58, 11 October 2006 (UTC)
Also, the valve dimensions are not to the usual scale. The exhaust valve should be the larger of the two to facilitate removal of the increased volume of gas that expanded during the combustion process.
