1. What is Swept Volume?

Swept Volume is the volume between the top dead center (TDC) and bottom dead center (BDC) in an engine cylinder. It represents the volume displaced by the piston as it moves through one complete stroke.

2. How Does the Calculator Work?

The calculator uses the Swept Volume formula:

Where:

• \( Vs \) — Swept Volume (m³)
• \( \pi \) — Archimedes' constant (approximately 3.14159)
• \( Dic \) — Inner Diameter of Cylinder (m)
• \( L \) — Stroke Length (m)

Explanation: The formula calculates the volume of a cylinder using the cross-sectional area (π/4 × Dic²) multiplied by the stroke length.

3. Importance of Swept Volume Calculation

Details: Accurate swept volume calculation is crucial for engine design, performance analysis, compression ratio determination, and efficiency calculations in internal combustion engines.

4. Using the Calculator

Tips: Enter the inner diameter of cylinder in meters, stroke length in meters. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between swept volume and clearance volume?
A: Swept volume is the volume displaced by the piston, while clearance volume is the volume remaining when the piston is at top dead center.

Q2: How does swept volume affect engine performance?
A: Larger swept volume generally means more power output, as it allows more air-fuel mixture to be burned per cycle.

Q3: Can this formula be used for any cylindrical volume calculation?
A: Yes, this is the standard formula for calculating the volume of any right circular cylinder.

Q4: What units should be used for accurate calculations?
A: Consistent units must be used. The calculator uses meters, but the formula works with any consistent unit system.

Q5: How is swept volume related to engine displacement?
A: Engine displacement is the total swept volume of all cylinders in an engine, typically measured in liters or cubic centimeters.
