Engine displacement, also known as engine capacity or cylinder displacement, is a measurement of the total volume of all the cylinders in an internal combustion engine. It’s a crucial parameter used in engine design and specifications. Here’s the formula, definition, and SI unit for engine displacement:
Engine Displacement (V): Engine displacement represents the total volume swept by all the pistons in the engine cylinders as they move through their strokes. It is typically measured in liters (L) or cubic centimeters (cc).The formula for calculating engine displacement depends on the engine’s configuration:
For Inline Engines (e.g., inline-four or inline-six):
- Bore: Bore is the diameter of each cylinder, typically measured in millimeters (mm) or inches (in).
- Stroke: Stroke is the length of the piston’s travel within the cylinder, typically measured in millimeters (mm) or inches (in).
- Number of Cylinders: This represents the total number of cylinders in the engine.
