Engine Displacement Volume Calculator







Formula

The formula to calculate the Displacement Volume (DV) is:

\[ \text{DV} = \pi \times \left(\frac{\text{BD}}{2}\right)^2 \times \text{SL} \times \text{NC} \]

What is Displacement Volume?

Displacement volume is a measure of the total volume of all the cylinders in an internal combustion engine. It is the space that is swept by the pistons as they move between the top and bottom of their stroke. Displacement volume is an important metric for understanding the size and power potential of an engine.

Example Calculation

Let's assume the following:

Step 1: Calculate the radius:

\[ \text{Radius} = \frac{\text{BD}}{2} = \frac{4}{2} = 2 \text{ inches} \]

Step 2: Calculate the displacement volume:

\[ \text{DV} = \pi \times 2^2 \times 3.5 \times 8 = \pi \times 4 \times 3.5 \times 8 \approx 351.86 \text{ cubic inches} \]

Therefore, the displacement volume (DV) is approximately 351.86 cubic inches.
