1. What is Engine Capacity?

Engine capacity, also known as displacement, is the total volume of all the cylinders in an engine. It's a key specification that indicates the size and potential power output of an engine, typically measured in cubic centimeters (cc) or liters (L).

2. How Does the Calculator Work?

The calculator uses the engine capacity formula:

\[ Capacity_{bs} = \pi \times \left(\frac{B_{bs\_cap}}{2}\right)^2 \times S_{bs\_cap} \times N_{bs\_cap} \]

Where:

\( \pi \) — Mathematical constant (approximately 3.14159)
\( B_{bs\_cap} \) — Bore diameter in millimeters
\( S_{bs\_cap} \) — Stroke length in millimeters
\( N_{bs\_cap} \) — Number of cylinders

Explanation: The formula calculates the volume of a single cylinder (π × radius² × stroke) and multiplies it by the number of cylinders to get the total engine displacement.

3. Importance of Engine Capacity

Details: Engine capacity is a critical factor in determining an engine's power output, fuel consumption, and emissions. Larger engines typically produce more power but consume more fuel. Engine capacity is also used for vehicle classification, taxation, and racing regulations in many countries.

4. Using the Calculator

Tips: Enter the bore and stroke measurements in millimeters, and the number of cylinders. All values must be positive numbers. The calculator will compute the engine capacity in cubic centimeters (cc).

5. Frequently Asked Questions (FAQ)

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 inside the cylinder.

Q2: How does engine capacity relate to power output?
A: Generally, larger engine capacity means more potential power, but actual power depends on many factors including engine design, compression ratio, and forced induction.

Q3: Why is engine capacity measured in cc or liters?
A: Cubic centimeters and liters are standard volume measurements that provide a convenient way to compare engine sizes across different manufacturers and countries.

Q4: What is a typical engine capacity range?
A: Motorcycles: 50-2000cc, Cars: 800-8000cc, Trucks: 4000-16000cc. These are general ranges and exceptions exist.

Q5: How accurate is this calculation?
A: This provides the theoretical displacement. Actual working volume may differ slightly due to combustion chamber design and other factors.
