Errata - Balancing the Lancia V4 


​1)  pgs. 80-81:

If one recalculates the values using the formula, the listed cylinder offset of 19.34mm  ( for the Fulvia) should be shown as 18.94mm. The correct value was used to determine the reciprocating % of 21.5%.  Here are the calculations for the Fulvia:

              ​K = ½ * (1-e/L * (cot (crankpin offset angle)))
              K = ½ * (1 - (18.94mm/153mm) * (cot (12.27)))
              K = ½ * (1 -  ((.1238)* 4.597)
              K = ½* (1 - .5691)
              K = .215 or 21.5%

Note: the value of  e, used above, was used as perpendicular to the engine center line, but instead should be perpendicular to the cylinder bore angle. The change is minor: for the Fulvia 1.3, the value of K changes from 21.5% to 21.2%. Thanks to Paolo Varvara and Luca Landoli for noting this. 
2.     On pg. 35, in the text of the CEMB formula: cylinder bore angle is listed,  should be crankpin angle (one side only).
3.     On pg.75, Fessia's 1963 paper refers to the crankshaft of the engine 818.100 (Fulvia 2C). It should refer to 818.000.
