1. What is Stroke Volume?

Stroke Volume (SV) is the volume displaced by a single piston during one complete stroke in an internal combustion engine. It's a fundamental parameter in engine design and performance analysis.

2. How Does the Calculator Work?

The calculator uses the stroke volume formula:

\[ SV = \frac{Displacement}{Number\ of\ Cylinders} \]

Where:

\( SV \) — Stroke Volume (cc or cu.in per cylinder)
\( Displacement \) — Total engine displacement (cc or cu.in)
\( Number\ of\ Cylinders \) — Total cylinders in the engine

Explanation: The total engine displacement is divided equally among all cylinders to determine how much volume each cylinder displaces during operation.

3. Importance of Stroke Volume

Details: Stroke volume helps determine engine characteristics like torque output, combustion efficiency, and is used in calculating compression ratio. Larger stroke volumes generally produce more torque but may limit maximum RPM.

4. Using the Calculator

Tips: Enter total engine displacement in either cubic centimeters (cc) or cubic inches (cu.in), and the number of cylinders in the engine. All values must be valid (displacement > 0, cylinders between 1-16).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between stroke volume and displacement?
A: Displacement is the total volume for all cylinders, while stroke volume is the volume for just one cylinder.

Q2: How does stroke volume relate to engine power?
A: Larger stroke volumes can produce more torque, but power depends on how quickly the engine can rotate (RPM) and other factors.

Q3: What are typical stroke volume values?
A: Passenger cars typically range 300-600cc per cylinder, while performance engines may be 500-900cc per cylinder.

Q4: Does stroke volume affect fuel efficiency?
A: Yes, generally smaller stroke volumes (with more cylinders) can be more efficient at higher RPMs, while larger strokes are more efficient at lower RPMs.

Q5: Can I use this for two-stroke engines?
A: Yes, the calculation works the same, though two-stroke engines complete the cycle in one revolution versus two for four-strokes.
