Algodoo

Use this in your spawn/fuel engines to advance the timing as the RPM increases. Change the spring constant of the two white springs to adjust what speed the advance acts. Change the density of the two long blue bars to adjust how much advance it gives. The laser provided on the outer ring should be used as the ignition laser.

CONTROLS:
Up arrow to speed up the input
Down arrow to apply a brake to the input

Watch the tracers and see how they cause timing advance. Pause the simulation to see how much it actually changes the timing. Tha maximum advance here is 60 degrees.
