The compression ratio doesn't deal with the displacement, the bore and stroke do. If it's a modern engine it should say the size of the engine in liters. You can use this to convert the engine size to cubic inches. A 173ci engine is a 2.8L engine when converted.
The Stihl 039 saw has a 2-stroke engine with a displacement of 3.9 cubic inches. The related link will take you to the owner's manual.
One cylinder would have a displacement of 21.2 cubic inches. By multiplying this displacement by the number of cylinders, in this case 6, the total displacement would be approximately 127 cubic inches. Area of circle pi x radius squared x length of stroke = one cylinder's displacement. be sure to use same units for area as well as stroke.
To calculate the total piston displacement of a 6-cylinder engine, you can use the formula: [ \text{Displacement} = \text{Number of Cylinders} \times \left( \frac{\pi}{4} \times \text{Bore}^2 \times \text{Stroke} \right) ] For a bore of 4 inches and a stroke of 3.5 inches, the displacement is: [ \text{Displacement} = 6 \times \left( \frac{\pi}{4} \times (4^2) \times 3.5 \right) \approx 6 \times 44.0 \approx 264.0 \text{ cubic inches} ] Thus, the total piston displacement is approximately 264 cubic inches.
The displacement of the engine cylinder(s).
5.00 L = 305.12 cubic inches.
The cubic inch displacement of a 4.6-liter engine can be calculated by converting liters to cubic inches. Since 1 liter is approximately 61.024 cubic inches, a 4.6-liter engine would have a displacement of about 281.9 cubic inches (4.6 liters × 61.024 cubic inches/liter). Therefore, the 4.6-liter engine in the Toyota Tundra has a displacement of approximately 282 cubic inches.
Cubic inches of displacement in reference to a car is the volume of the cylinders in the engine in cubic inches. In most American muscle cars, part of the name refers to the displacement of the engine in cubic inches, for example the Chevrolet Chevelle SS454 has a 454 ci engine and the Oldsmobile 440 had a 440 ci engine.
