1. What is the CSG Engine Displacement Formula?

The CSG engine displacement formula calculates the total volume swept by all the pistons in an engine's cylinders. It's a fundamental measurement of engine size and potential power output.

2. How Does the Calculator Work?

The calculator uses the CSG displacement formula:

\[ Disp = \pi \times (B/2)^2 \times S \times 4 \]

Where:

\( Disp \) — Engine displacement (cm³)
\( B \) — Cylinder bore diameter (mm)
\( S \) — Piston stroke length (mm)
\( \pi \) — Mathematical constant Pi (approximately 3.1416)

Explanation: The formula calculates the volume of a single cylinder (πr²h) and multiplies by the number of cylinders (4) to get total engine displacement.

3. Importance of Engine Displacement Calculation

Details: Engine displacement is a key factor in determining engine performance, fuel efficiency, and emissions. It's used for vehicle classification, taxation purposes, and performance comparisons.

4. Using the Calculator

Tips: Enter bore and stroke measurements in millimeters. Both values must be positive numbers. The calculator will automatically compute the displacement in cubic centimeters.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 4 in the formula?
A: The multiplication by 4 assumes a standard 4-cylinder engine configuration. For different cylinder counts, this multiplier would change accordingly.

Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but many other factors like compression ratio, forced induction, and engine design also significantly impact power output.

Q3: What are typical bore and stroke values?
A: These vary widely by engine design. Modern engines typically have bore sizes between 70-100mm and stroke lengths between 70-95mm for passenger vehicles.

Q4: Why convert to cm³ instead of keeping in mm³?
A: Engine displacement is traditionally measured in cubic centimeters (cc) or liters, which are more practical units for expressing engine size than cubic millimeters.

Q5: Does this formula work for all engine types?
A: This formula works for any 4-cylinder piston engine. For engines with different cylinder counts, the multiplier (4) should be replaced with the actual number of cylinders.
