A B4 engine. Realistic in almost everything, except that it has only the front cylinder valves, that it shows only the power stroke (it's a 4 stroke), and the accelerator retrasses the stroke, when in a real engine it would inject less fuel.
Made for looks. I will never get strenght and looks as Gent does.
The stroke is represented with red for the upper, visible cylinders, and blue for the further cylinders.
The only controls are up/down to accelerate or deaccelerate. There's an automatic mechanism that starts the engine, and then deletes itself. Sometimes fails, like the valves, so if that happens, just undo sim start and play again.
The accelerator is mechanic.
Absolutely No Variables.
V2: I fixed two parts of the accelerator and it goes 10 rad/s faster. How the hell I did it?
Well, gent, fixed the valves, the pistons but not the cams. I've tested the circle-and-box design, and it doesn't work as smooth as this one. Test it yourself with this engine if you want, because a cam that is not round spinning at 20 rad/s makes shit the valves.
.001: Forgot the valve heads. Done, now it runs MUCH faster!
