Crankshaft rotation versus stroke Formula
Crankshaft rotation versus stroke Formula
(OP)
Does anyone have the formula to calculate crankshaft rotation in degrees versus stroke position? I have all of the stroke and rod length information.
Thanks.
Thanks.

the simple case, w/o pin offset or crank offset, is:
y.piston = a*cos(theta)+sqrt[r^2 - a^2*sin(theta)^2]
where "a" is the crank throw, and "r" is the conrod length. "Theta" is the crank angle from TDC.
