Calculating Displacement
Displacement is calculated utilizing the bore (cylinder diameter), stroke (distance the piston travels), and the variety of cylinders. The formulation sometimes used is: Displacement = (/4) bore stroke * variety of cylinders. For instance, an engine with a bore of 86mm, a stroke of 86mm, and 4 cylinders would have a displacement of roughly 1997 cc. Correct measurement of those parameters is essential; errors in bore or stroke measurements immediately translate to inaccuracies within the complete displacement worth.
