Engine Capacity Formula:
| From: | To: |
The engine capacity formula calculates the total displacement volume of an engine's cylinders. It represents the total volume of air/fuel mixture an engine can draw in during one complete cycle of all cylinders.
The calculator uses the engine capacity formula:
Where:
Explanation: The formula calculates the volume of a single cylinder (πB²S/4) and multiplies it by the number of cylinders to get total engine displacement.
Details: Engine capacity is a fundamental specification that indicates engine size and potential power output. It's crucial for vehicle classification, performance comparison, and engineering design.
Tips: Enter bore and stroke measurements in millimeters, and the number of cylinders. All values must be positive numbers with bore and stroke greater than zero, and at least one cylinder.
Q1: Why is engine capacity measured in cubic centimeters?
A: Cubic centimeters (cc) provide a convenient unit for measuring engine displacement, with 1000cc equaling 1 liter, which is commonly used for engine size classification.
Q2: How does engine capacity relate to engine power?
A: Generally, larger engine capacity can produce more power, but actual power output also depends on factors like engine design, compression ratio, and forced induction.
Q3: What are typical engine capacity ranges?
A: Motorcycles: 50-2000cc, Cars: 800-8000cc, Trucks: 4000-16000cc. Modern passenger cars typically range from 1000-6000cc.
Q4: Are there different formulas for different engine types?
A: The basic formula applies to all piston engines, but rotary engines (Wankel engines) use a different calculation method based on rotor geometry.
Q5: How accurate is this calculation for real engines?
A: This provides theoretical displacement. Actual effective displacement may vary slightly due to manufacturing tolerances, combustion chamber design, and piston crown shape.
