WebApr 10, 2024 · Then turn the crank to position the piston exactly 0.100 inch below the deck surface. Now place some light grease on the flat plastic plate and position it over the cylinder with the small hole near the upper edge of the cylinder. Rotate your engine stand to position that hole in the plate as the highest point. WebTo calculate the compression ratio of an engine, use the following formula: compression ratio = V d + V c V c Vd is the displacement volume of the motor, or the volume displaced by the piston from the start to the end of the stroke. Vc is the clearance volume of the motor, or the remaining space left when the piston is at the end of the stroke.
