To calculate engine displacement, square the bore diameter (D²), multiply by the stroke length (S) and the number of cylinders (N), and then multiply by π/4. This will give you the total engine displacement.
Welcome to the Bore X Stroke Calculator! Have you ever wondered how the size of an engine’s cylinders affects its performance? The bore and stroke of an engine play a crucial role in determining its displacement and overall characteristics. Let’s dive into how this calculator works and why it’s essential for engine design and optimization.
Formula:
Variable | Meaning |
---|---|
ED | Engine displacement (in cubic centimeters or liters) |
D | Bore (cylinder diameter in inches or millimeters) |
S | Stroke (piston travel length in inches or millimeters) |
N | Number of cylinders |
π | Pi (approximately 3.14159) |
Solved Calculation:
Example 1:
Given Values:
- D = 3.5 inches
- S = 4 inches
- N = 6 cylinders
Calculation | Instructions |
---|---|
ED = | Square the bore diameter, multiply by stroke and cylinder count, then multiply by π/4. |
ED = | Perform the calculations for the bore and stroke. |
ED = | Multiply the bore, stroke, and number of cylinders. |
ED ≈ 231 cubic inches | The result gives the engine displacement in cubic inches. |
Answer: ED ≈ 231 cubic inches
Example 2:
Given Values:
- D = 88 mm
- S = 96 mm
- N = 4 cylinders
Calculation | Instructions |
---|---|
ED = | Square the bore diameter, multiply by stroke and cylinder count, then multiply by π/4. |
ED = | Perform the calculations for the bore and stroke. |
ED = | Multiply the bore, stroke, and number of cylinders. |
ED ≈ 2335236.5 mm³ | The result gives the engine displacement in cubic millimeters. |
Answer: ED ≈ 2335.24 cc (cubic centimeters)
What is Bore X Stroke Calculator ?
The Bore x Stroke Calculator is a simple tool that anyone can use to figure out how big an engine is. The bore is how wide the engine cylinder is, and the stroke is how far the piston inside the cylinder moves up and down.
When you put these numbers together, you can calculate the engine’s size, which is measured in cubic centimeters (cc) or cubic inches. By knowing the engine size, you can understand how powerful the engine is and how well it will perform.
Using this calculator is easy! Just type in the numbers for the bore and stroke, and it will quickly show you the engine’s size. You don’t need to be a mechanic or an expert – this tool breaks it down so everyone can understand.
The bore-stroke ratio will also help you see if the engine is made more for power or speed, depending on the balance between the width of the cylinder and the piston’s movement. This simple tool can help you learn more about engines and how they work!
