Understanding Engine Displacement

Engine displacement is a crucial metric in automotive engineering that measures the total volume of all the cylinders in an engine. It represents the volume swept by all pistons from their highest point (Top Dead Center) to their lowest point (Bottom Dead Center).

How It's Calculated

The formula used is:

Displacement = π/4 × bore² × stroke × number of cylinders

Key Terms

• Bore: The diameter of each cylinder
• Stroke: The distance the piston travels inside the cylinder
• Cylinders: The number of combustion chambers in the engine
