1. What is Engine Stroke Volume?

Engine stroke volume, also known as cylinder displacement, is the volume swept by a piston in a single stroke. It's a fundamental measurement in engine design that helps determine engine size and performance characteristics.

2. How Does the Calculator Work?

The calculator uses the stroke volume formula:

\[ Stroke Volume = \pi \times \left(\frac{Bore}{2}\right)^2 \times Stroke \]

Where:

Explanation: The formula calculates the volume of a cylinder using the bore as diameter and stroke as height.

3. Importance of Stroke Volume Calculation

Details: Stroke volume is crucial for determining engine displacement, which directly affects power output, torque characteristics, and fuel efficiency. It's a key factor in engine design and performance tuning.

4. Using the Calculator

Tips: Enter bore and stroke measurements in millimeters. Both values must be positive numbers. The calculator will compute the volume of a single cylinder.

5. Frequently Asked Questions (FAQ)

Q1: How is total engine displacement calculated?
A: Multiply the single cylinder stroke volume by the number of cylinders in the engine.

Q2: Why are bore and stroke important in engine design?
A: The bore/stroke ratio affects engine characteristics - longer strokes typically produce more torque while larger bores allow higher RPM operation.

Q3: How do I convert mm³ to cc or liters?
A: 1000 mm³ = 1 cc (cubic centimeter), and 1000 cc = 1 liter. Divide mm³ by 1000 to get cc.

Q4: Does stroke volume account for combustion chamber volume?
A: No, stroke volume only measures the swept volume. Compression ratio calculations require adding combustion chamber volume.

Q5: What's a typical stroke volume range for automotive engines?
A: Common values range from 300-600 mm³ for motorcycles to 500-1000 mm³ for automotive engines per cylinder.
