How to Calculate Engine Capacity
Understanding Engine Capacity Calculation
Engine capacity, often referred to as engine displacement, represents the total volume of all the cylinders within an engine. It is indicative of the engine's power and efficiency. To calculate it, the formula used is 0.7854 x bore x bore x stroke x number of cylinders. Here, 'bore' is the diameter of each cylinder, and 'stroke' is the length the piston travels within the cylinder, across all cylinders in the engine.
Tools Required for Calculation
For practical and precise calculations, the use of an Engine Displacement Calculator is recommended. This tool simplifies the computation by using the provided inputs: bore, stroke, and number of cylinders. Both metric and US standard units are compatible, facilitating a broad utility regardless of your regional measurement system.
Calculating Engine Displacement
To perform the calculation manually or via the calculator, first measure or gather the bore and stroke dimensions of your engine's cylinders. Next, count the total number of cylinders. Apply these values in the formula or input them into the displacement calculator to get the engine capacity, expressed usually in cubic centimeters (cc) or liters.
Conclusion
Calculating engine capacity is essential for understanding engine size and power. Accurate measurements and the correct application of the formulas or utilisation of a digital calculator will provide you with a reliable figure of your engine’s displacement.
How to Calculate Engine Capacity
Understanding Engine Displacement
Engine capacity, or displacement, measures the total volume of air displaced by an engine's cylinders. It is crucial for understanding engine size and power output.
Step-by-Step Calculation Guide
To calculate engine displacement, begin by determining the engine cylinder bore area. Multiply this area by the crankshaft stroke length. Use the formula: cylinder bore area x crankshaft stroke.
Next, multiply the result by the number of cylinders in the engine using the formula: cylinder Bore Area x Crankshaft Stroke x Number of Cylinders.
This calculation provides the engine displacement, representing the engine's total air volume capacity.
Choosing Measurement Units
Perform the calculation in either metric (cc, L) or U.S. standard units (cubic inches). Select the unit that best suits the intended use or geographical norms.

Examples of Calculating Engine Capacity
Example 1: Four-Cylinder Engine
To calculate the engine capacity of a four-cylinder engine, measure the cylinder bore and the piston stroke. Suppose the bore (diameter of the cylinder) is 85 mm and the stroke (distance the piston moves) is 88 mm. The formula to calculate the volume of one cylinder is: Volume = π × (bore/2)^2 × stroke. Converting the dimensions to centimeters, you have a bore of 8.5 cm and a stroke of 8.8 cm. Therefore, the capacity for one cylinder is approximately 508.938 cm³. For all four cylinders, multiply by four, which results in a total engine capacity of approximately 2035.75 cm³.
Example 2: V8 Engine
For a V8 engine, repeat the same procedure with appropriate dimensions. If a V8 engine has a bore of 90 mm and a stroke of 95 mm, converting to centimeters gives a bore of 9 cm and a stroke of 9.5 cm. Calculating for one cylinder yields about 638.172 cm³. With eight cylinders, this V8 engine has an engine capacity of about 5105.376 cm³.
Example 3: Inline Six-Cylinder Engine
In the case of an inline six-cylinder engine, let's use the bore of 75 mm and a stroke of 73 mm. Converted to centimeters, the bore is 7.5 cm and the stroke is 7.3 cm. This results in a capacity of approximately 324.407 cm³ per cylinder. Multiplied by six, the total capacity of the engine comes to approximately 1946.442 cm³.
Understanding these calculations helps in comprehensively assessing engine size and performance. Different configurations and sizes influence the power output and efficiency of an engine, underlining the importance of precise calculations.
