Overall I think you did a good job on these engines, but they both seem to be a little unstable. That is, the speeds keep randomly fluctuating. Also, I was wondering how you would throttle the engine up and down, especially the "realistic" one with cams. If you could work out some of the bugs, this might be a great muscle for a car or other vehicle.

Great!!!!

I might try to improve these someday, but not now. i've got like 5 unfinished projects. Also the engines are unstable mainly because the cam one relies on collisions to transmit energy to the "crankshaft" (or however you'd call that ), and the rod one only has 2 rods, and the left and right pistons push the upper and lower pistons to transmit the power to the crankshaft, so you have 4 axles acting only as a way to transmit forces. (you can lower the simulation speed and you'll see that the upper and lower pistons are pushed to the sides when the side ones ignite)

If s_noonan's perfect rail thingy actually worked with less lag and could use axles without them stretching, this would be solved. but i even asked about something like that in the forum a lot of time ago (Pistons that wouldn't stretch) and even if 3/4 of the people wanted those, no one even bothered at doing that. And that was on the 1.9.xb times

Thanks Eduardo!

Link how big should be a normal engine? somewere in the 0.1m Zone??

@The Linkage i also fixed my Oversized Boxer Engine. Check it out.

Depends on the engine. Old Ford V6s have a total length of 60 cm, while a 2.0 I4 engine might have 50 cm length. we even have a v8 Ford engine at school and its length is that of your whole arm

0.1 m is 10 cm lmao

Wow this engine runs fast! I had never heard of this engine deisign before, nice rendition!
