This wouldn't work in real life as the valve opening times are too short and the front valve (which I guess is the intake) opens when the piston is moving to the front. Also on a 4 stroke engine you have to compress the fuel and then it would blow up, the piston should go all the way right, and THEN an exhaust valve should open until the piston goes all the way left, then the intake opens until it's all the way right, then the piston does half a flywheel turn to compress the fuel, and the process repeats. I've got a demo (click here)

The Linkage, this is just a prototype, i know how engines work this is my first attempt in this game, i could use some help

Well the first tip i'd give you is to ALWAYS use the grid. No matter what, don't even turn the grid off when you're building something. Also, you should use 120 Hz for every scene (go to settings => Simulation => change the frequency slider to 120), and use very high densities for everything, even if things end up weighing a lot more than in reality. Density makes collisions better, that's why

Look....nice? i dont know lol i dont know anything about engens so eh. good for a first time in the game tho. (i have seen VERY worse lol)

Thanks guys, i thought this would work with steam

dont thank us thank your self you are the one who made it
