How do you Calculate Engine Displacement?
Engine displacement is calculated using many variables. The variables that you will need to gather include:
- Number of cylinders
- Bore diameter
- Stroke length
With these values, you now need to find the radius which can be done by dividing the bore's diameter by 2. Then you can use the following formula to find a single cylinder's total volume:
CV is equal to the cylinder volume and SL is equal to stroke length (in meters). After this is done you now will simply multiply your result by the total number of cylinders in the vehicle, and you will have your total engine displacement!
Understanding Your Results
Your result is automatically displayed as cubic inches as it is one of the more popular units of measurement for this type of metric, but another commonly used unit is liters. So once you hit calculate and get your engine displacement value, that is how much volume and space your engine's cylinders have in total.
How to Use the Engine Displacement Tool
If you are trying to calculate an engine's displacement, you are in luck. It can easily be done with a tool like this. The steps include:
- Enter the total number of cylinders the engine has.
- Enter the diameter of the bore (the opening at the end of the cylinders).
- Enter the stroke length (the total length the pistons are able to move within the cylinder).
- Hit calculate and get your engine displacement value in seconds!
Example Calculation
Let's say you have a vehicle that has the VQ35DE engine in it, let's find the engine displacement. First, we need to identify our variable values. It is a six-cylinder, it has a bore diameter of 95.5 mm, and a stroke length of 81.4 mm. After we insert these numbers into the tool and select the correct unit of measurement, we can calculate it and get an engine displacement value of 213.49 cubic inches or 3.5 liters.
