Engine Displacement Formula:
From: | To: |
Engine displacement is the total volume of all the cylinders in an internal combustion engine. It's a key specification that indicates engine size and power potential, typically measured in cubic inches (ci) or liters (L).
The calculator uses the engine displacement formula:
Where:
Explanation: The formula calculates the volume of a single cylinder (πr²h) and multiplies by the number of cylinders.
Details: Displacement directly relates to engine power and torque. Larger displacement engines typically produce more power but may have lower fuel efficiency.
Tips: Enter bore and stroke in inches, and number of cylinders. All values must be positive numbers.
Q1: How does displacement relate to engine power?
A: Generally, larger displacement means more power potential, but efficiency, design, and forced induction also play major roles.
Q2: What's the difference between bore and stroke?
A: Bore is cylinder diameter, stroke is how far the piston travels. Together they determine cylinder volume.
Q3: How do I convert cubic inches to liters?
A: Multiply cubic inches by 0.016387 to get liters (1 liter = 61.0237 cubic inches).
Q4: What's a typical displacement range?
A: Passenger cars: 1.0-6.0L (61-366ci), trucks: 4.0-8.0L (244-488ci), motorcycles: 0.25-2.0L (15-122ci).
Q5: Does displacement affect fuel economy?
A: Generally yes - larger engines consume more fuel, but modern technologies can mitigate this relationship.
