Engine Capacity Calculator

Calculate engine displacement in cubic centimeters (cc) based on bore and stroke dimensions.

Input Parameters

Calculation Results

Calculation Formula

Engine Capacity (cc) = π × (bore/2)² × stroke × cylinder_count

Where:
π = 3.14159
bore = Piston diameter in cm
stroke = Piston travel in cm
cylinder_count = Number of pistons in the engine

Engine Capacity Calculator Usage Guide

Learn how to use the Engine Capacity Calculator and understand engine displacement measurements

How to Use This Calculator

  1. Enter the bore diameter of your engine in centimeters (cm).
  2. Enter the stroke length of your engine in centimeters (cm).
  3. Specify the number of cylinders in the engine (typically 4, 6, 8, etc.).
  4. Click the "Calculate" button to compute the engine displacement.

Understanding Engine Capacity

Engine capacity, also known as displacement, is the total volume of air and fuel mixture an engine can draw in during one complete cycle. It's measured in cubic centimeters (cc) or cubic inches. A larger displacement generally means more power output, but modern engines achieve efficiency through other technologies.

Important Notes

  • Ensure all measurements are in centimeters for accurate results.
  • This calculator provides an approximate displacement based on bore and stroke alone.
  • Actual engine displacement may vary due to other factors like valve overlap and combustion chamber volume.
  • For car models, check the manufacturer's specifications for the exact engine displacement.
