A 4-cylinder Honda has a bore of 8 cm and a stroke of 9.1 cm. Find the piston displacement in cubic centimeters. Use the formula V_d = 0.785 x d² x s x n
where: d is the bore or diameter of the piston
v is the volume of the cylinders
s is the stroke or piston travel length
n is the number of pistons

Solution

V_d = 0.785 x d² x s x n
V_d = (0.785)(8²)(9.1)(4)
V_d = (0.785)(64)(9.1)(4)
V_d = 1828.736
V_d= 1829 cubic centimeters
