Summit Displacement Formula:
| From: | To: |
Engine displacement is the total volume of all the cylinders in an internal combustion engine. It's a key measurement that indicates the engine's size and power potential, typically measured in cubic inches, cubic centimeters, or liters.
The calculator uses the engine displacement formula:
Where:
Explanation: The formula calculates the volume of a single cylinder (π × radius² × stroke) and multiplies it by the number of cylinders to get total displacement.
Details: Engine displacement is a critical factor in determining an engine's power output, torque characteristics, and fuel consumption. Larger displacements generally produce more power but may consume more fuel.
Tips: Enter the number of cylinders, bore diameter in inches, and stroke length in inches. All values must be positive numbers for accurate calculation.
Q1: What's the difference between bore and stroke?
A: Bore is the diameter of each cylinder, while stroke is the distance the piston travels within the cylinder.
Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but efficiency, design, and technology also play significant roles.
Q3: Can I use metric measurements?
A: This calculator uses inches, but you can convert metric measurements (1 inch = 25.4 mm) before entering values.
Q4: What is a typical displacement range for car engines?
A: Modern car engines typically range from about 60 to 500 cubic inches (1.0 to 8.2 liters), with most falling between 120-300 cubic inches (2.0-5.0 liters).
Q5: How does displacement affect fuel economy?
A: Generally, larger displacement engines consume more fuel, but modern technologies like turbocharging and variable displacement can improve efficiency.
