A 4-cylinder engine has a bore of 3 inches and a stroke of 3 inches. What’s the total piston displacement
saveliy_v [14]

<u>Answer:</u>

Piston displacement = 84.8

<u>Step-by-step explanation:</u>

We will find the volume of the cylinder in order to find the piston displacement.

Here, (bore = diameter, so r = diameter/2) (height = stroke)

Volume = \pi r^2h =3.14\times1.5^2\times 3 = 21.2 cubic units

Since the engine has 4 cylinders, so we will multiply the piston displacement by 4 to get:

Piston displacement = 21.2 \times 4 = 84.8
