The engine displacement of an automobile is the volume through which the piston moves from high to low position. If an bore
engine has n cylinders, the displacement is D=s • stroke. n, where the bore is the diameter of the cylinder
2
and stroke is the length of the piston's travel.
1. If bore= and stroke = h, simplify the expression, D, in terms of k and h for 8 cylinders.
2. If the bore is 4 inches, the stroke is 3.4 inches, and the engine has four cylinders, what is the displacement? Round
your answer to the nearest tenth of a cubic inch.
