Calculating Engine Displacement: How To Determining the Size of an Engine
Engine displacement refers to the total volume of air displaced by all the pistons in an internal combustion engine. It serves as a measure of the combined cylinder volume within the motor and is vital for determining factors like compression ratio and indicating engine size.
To calculate engine displacement, you can use the following formula:Displacement = (π/4) × b² × s × c(alert-success)
In this equation, "b" represents the bore size, "s" denotes the stroke length, and "c" signifies the number of cylinders.
Let's illustrate the calculation by considering an example. Suppose we have a motor with a bore size of 3.7 inches, a stroke length of 3.2 inches, and 6 cylinders.Displacement = (π/4) × 3.7² × 3.2 × 6Displacement = 0.78539816339 × 13.69 × 3.2 × 6Displacement = 262.682 cu in(alert-passed)
Engine displacement is often measured in liters, cubic centimeters (cc), or cubic inches (cu in). If the bore and stroke measurements are in inches, the result from the above formula will be in cubic inches. If the measurements are in centimeters, the result will be in cubic centimeters.
To convert the displacement to liters, you can use a cubic inches to liters conversion calculator or multiply the cubic inches by 0.016387.
