When 6 cylinder engine has a bore of 4 inches and a stroke of 3.5 inches what and the total piston displacement?

To calculate the total piston displacement of a 6-cylinder engine, you can use the formula:

[ \text{Displacement} = \text{Number of Cylinders} \times \left( \frac{\pi}{4} \times \text{Bore}^2 \times \text{Stroke} \right) ]

For a bore of 4 inches and a stroke of 3.5 inches, the displacement is:

[ \text{Displacement} = 6 \times \left( \frac{\pi}{4} \times (4^2) \times 3.5 \right) \approx 6 \times 44.0 \approx 264.0 \text{ cubic inches} ]

Thus, the total piston displacement is approximately 264 cubic inches.
