Algodoo

I see that you use ignition timing to determine engine rotation direction. That is an interesting concept but it doesn't explain how you handle the timing of fuel/air intake and exhaust gases which are things usually handled via valves and cam shafts. I guess that happens through the unseen magic of Algodoo!

Except for that little detail, you did a good job on the scene.

this scenario that i made is about the marine very large diesel two stroke engine for ship propulsion plant.The laser that i use for the ignition show the diesel ignition from the compresse air inside the combustion chamber.I usually make diesel engine because i have work alot at them and i believed that is better from an otto engine depends on work we need.In other scenario i will explain the injection system as better as i can in 2d dimensions.Thanks for the good comment my friend.Have a nice and happy new year with good life for all the world and PEASE EVERYWHERE!!!
