The distance a piston travels within the cylinder bore, from the very top to the very bottom. This limit is the stroke.
This is the formula. Area = .7854 x bore^2 A = .7854 x 30.25 (5.5^2) A= 23.75 sq.in Volume = Area x stroke 23.75 x 5.5 = 130.625 cubic inches. *This is just one piston. If engine was a nine cylinder then 130.625 x 9 = 1175.625*
Compression ratio is exclusive to each cylinder, though they will all have the same result if they are the same dimensionally ( and they always are) > Divide the total engine capacity by the number of cylinders, this gives the capacity or swept volume of each cylinder (bore * stroke) > So in a 2.0 (2000 cc) litre 4 cylinder engine, each cylinder has a 2000 / 4 = 500 cc swept volume (bore * stroke) > The combustion chamber is the volume remaining at top dead centre (TDC) > Compression ratio = volume at BDC (swept volume + volume at TDC) / volume at TDC
The displacement of a 302ci Ford V8 bored 60-over is 310.71ci V v V To calculate cylinder volume you should know the bore and stroke sized of an engine. Say a 350ci Chevy V8 bored 60-over: Normal bore of a 350 is 4" in diameter, so 60-over would measure 4.060" diameter bore. Stroke of a 350 is 3.48". Equation for measuring internal displacement of an engine is: Bore Radius^2 * 3.14 (Pi) * Stroke * # of cylinders = Internal Displacement So using that formula, we would divide of the bore diameter in half to get the radius. Radius is 2.03". Then calculate 2.03 to the 2nd power (2.03*2.03) is 4.1209". Now multiply 4.1209" by Pi which is 3.14. That equals 12.939626". This represents the 2-dimensional surface area of the bore. Now multiply that by the length of the cylinder stroke, which on this engine is 3.48". That equals 45.02989848 cubic inches (cylinder volume). You can round off the numbers to make it more simple, that's fine. Now 45.02989848 is the volume of a single cylinder of that engine. We know the 350ci has 8 cylinders, so we would now multiply by 8 to get the final calculation. The answer is 360.24 cubic inches. I hope this explanation helps a little.
That can be calculated for individual cylinders by the formula :- Pi R (2) x length of piston stroke.
Enlarging the cylinder bore will increase cc's in a 2 stroke and ci's ina 4 stroke.....

The bore of a cylinder is the diameter of the cylinder in an engine. It is directly related to the displacement of the engine, which affects the power output. A larger bore can increase the displacement, allowing for more air and fuel mixture to enter the cylinder during the power stroke, resulting in higher power output.
1000 cc
I'm not a mechanic / technician but as far as I know that is where the engine cylinder bore is larger than the stroke
If Measuring in mm, ( Bore x Bore x Stroke x .7854 ) / 1000 = cc's
Bore = the (internal) diameter of the cylnder hole in the engine block. Stroke = the distance the piston travels up (or down) the bore during its' cycle. If you multiply the bore dimension by the stroke dimension you will get the volumetric displacement of that cylinder. thus, Vd = (3.1416/4) (dia.) squared x Stroke
Bore is the diameter of the piston/cylinder, stroke is the distance the piston can travel between its highest position and its lowest position in the cylinder.
The Bore of a 350 cid engine is 4.00, the stroke is 3.48 inch..
4inch bore 3.25 stroke formula bore x bore times stroke times .7854= cid
I assume you mean engine displacement? To calculate engine displacement, use this formula: Bore x bore x stroke x .7854 x number of cylinders.
The bore and stroke is---3.740 bore and 3.480 stroke. STOCK 305
