## Understanding Engine Displacement

**Engine displacement** refers to the total volume of all the cylinders in an engine and is a key indicator of engine capacity. It is measured in cubic centimeters (cc) or cubic inches (cu in). Our engine displacement calculator helps you determine this value using the dimensions of the engine's cylinders and pistons.

## What Does Engine Displacement Mean?

When you see "cc" or "cubic inches" next to an engine's specifications, it indicates the engine's displacement. This measurement represents the volume swept by the piston within the cylinders.

Engine displacement affects the engine's power output and fuel consumption. For instance, a typical Formula One car engine might have a displacement of 1600 cc or 1.6 liters.

Engine displacement can be calculated with the formula:

V = N * L * π * D² / 4

where:

- V = Engine displacement
- N = Number of cylinders
- D = Bore diameter
- L = Stroke length

The stroke length (L) is the distance the piston travels within the cylinder. This formula calculates the volume of a single cylinder, and by multiplying it by the number of cylinders, you get the total engine displacement.

## How to Use the Engine Displacement Calculator

To find the engine displacement using our calculator:

**Enter the Number of Cylinders (N)**: Input the total number of cylinders in the engine.**Enter the Bore Diameter (D)**: Input the diameter of each cylinder's bore in centimeters.**Enter the Stroke Length (L)**: Input the length of the piston stroke in centimeters.**Calculate**: Click the "Calculate" button to get the engine displacement in cubic centimeters (cc) or cubic inches (cu in).

## Example Calculation

**Calculate the displacement for a 4-cylinder engine** with a bore diameter of 50 mm and a stroke length of 250 mm.

**Convert Bore and Stroke to Centimeters**: Bore = 5 cm, Stroke = 25 cm.**Number of Cylinders (N)**: 4**Calculate Engine Displacement**:

V = 4 * 250 * π * 50² / 4 = 1,963,495 mm³ ≡ 119.82 cu. in.

The result is approximately 119.82 cubic inches.
