Question

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

Answer 1

Answer:

Piston displacement = 84.8

Step-by-step explanation:

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
