Engine Displacement **Calculator** This Engine Displacement **Calculator** provides calculations for engine displacement based on either the metric or US standard system. Engine displacement is determined by calculating the engine cylinder **bore** area multiplied by the **stroke** of the crankshaft, and then multiplied by the number of cylinders. Read More. The diameter of the piston, and the inside diameter of the cylinder, is called the **bore** - B . So the area A of the head of the piston is pi (3.14159) times the diameter squared divided by four. A = pi * B^2 / 4. The volume swept out during any complete **stroke** is the piston area times the **stroke**: V = pi * S * B^2 / 4. May 25, 2018 · Displacement is calculated from other engine measurements. You will need to know the Cylinder **Bore** Diameter and **Stroke** Length. Use one of the formulas below. c.i.d. = 0.7854 x **Bore** 2 (in.) x **Stroke** (in.) x Number of Cylinders. **cc** = (0.7854 x **Bore** 2 (mm) x **Stroke** (mm) x Number of Cylinders) ÷ 1,000.. The bike's manual gives the following technical specs. Maximum permissible rpm. 7500. Maximum rated capacity (horsepower) 35 kW at 6500 rpm. Maximum **torque**. 57 N.M. at 5200 rpm. From this we can see that the difference between max **torque** and max power is 1300rpm - quite a big gap that we must utilise for different conditions. In a 4-cylinder engine, the** stroke** length is 10 cm and the bore is 4.5 cm. What is the displacement? Since N = 4, S = 10, and B = 4.5, the displacement in cubic centimeters is D = ( π /4) (4.5²) (10) (4) = 636.1725 cc, or 0.636 L. Example 2: A 6-cylinder engine has a displacement of 200 cubic inches and a** stroke** length of 3.75 inches. This means that if you want to determine the displacement, the first step is to measure or locate the **bore** and **stroke** of its cylinders.
