Piston Travel vs Crank Rotation

Post by Luders »

For anyone using a programmable ignition who needs to calculate the above, I found this useful calculator

http://www.dansmc.com/mc_software2.htm

a = ignition advance in degrees
T = ignition advance in mm
R = engine stroke divided by 2
L = conrod length in mm

T = L + R·(1-cos a)-√L² -(R·sin a

Sorry, the equation was the best I could get it to look using the character map
