The hollow area between the top of the piston and the bottom of the cylinder head is known as the combustion chamber. This space is crucial in an internal combustion engine as it is where the air-fuel mixture is compressed and ignited, leading to the power stroke. The design and volume of the combustion chamber significantly influence the engine's efficiency, power output, and emissions.
cc=cubic centimeter= displacement=the amount of area displaced between the bottom of the stroke and top of the stroke of the piston.
In a internal combustion engine, a cylinder ridge is an unworn area around the top of the cylinder wall. In that engine, the piston moves up and down in the cylinder, and the rings seal the piston in that cylinder. But the rings are spaced "down a bit" from the top of the piston. And when the piston reaches top dead center in the cylinder, the rings haven't gone all they way to the top of the cylinder. They end up wearing the cylinder out "underneath" that top area. In other words, it's the top part of the cylinder that is not in contact with the piston rings. It's the "unworn" part, if you will.
Piston projection refers to the distance that a piston extends upward from the top of the cylinder when the engine is at top dead center. This measurement is important for ensuring proper engine performance and clearance between components.
The distance a piston travels within the cylinder is called the stroke. It is the distance between the top dead center (TDC) and the bottom dead center (BDC) positions of the piston.

The Pixie Hollow code for pumpkin top is 525350.
Yes, the material, thickness and possibly style of piston ring(top ring) can be different.
it's when the piston is all the way up
Putting it simply as the piston moves upwards on the compression stroke the fuel / oil / air mixture is compressed from a large volume into the much smaller area between the top of the piston and the cylinder head as it reaches TDC. The volume of this area is the squish volume. In other words it has been "squished". The velocity and heat generated in this process combined with the geometry of the head and piston affects the combustion process as it is pushed towards the spark etc
