It is the space between the top of the piston and the bottom of the cylinder head. Great care should be used when putting an engine back together to make sure the bump clearance is not 0 so that the piston will not hit the head cylinder.

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 volume occupied by the cylinder when the piston is at top dead centre is called clearence valume.
Well...... you need A LITTLE bit of clearance for the gas mixture to lubricate the piston and cylinder. Plus your piston expands when it gets hot.
engines cease because, it is our misconception that the cylinder of the engine is cylindrical,in actual the cylinder walls are slightly slanting. and th diameter of the piston is a bit less than that of the cylinderwalls,which is known as clearance,,which is formulated for the smooth running of piston,,but when the temperature inside the cylinder increases above a certain level,the walls of the cylinder and the piston expands.but the expansion ratio is different for both,,as the cylinder is made of cast iron and piston with aluminium,which decreases the gap to certain level that there is no movement of piston,which is called as ceasinf of engine.
Clearance volume in a car engine is calculated by determining the volume of the combustion chamber when the piston is at the top dead center (TDC). To find it, you can use the formula: Clearance Volume = Total Cylinder Volume - Displacement Volume. The total cylinder volume is the volume of the cylinder when the piston is at the bottom dead center (BDC), while the displacement volume is the volume displaced by the piston as it moves from TDC to BDC. This calculation helps in understanding the engine's compression ratio and efficiency.

The piston is prevented from tipping in the cylinder by the piston rings, which provide stability and guidance as the piston moves up and down within the cylinder. Additionally, the piston skirt design and cylinder wall clearance also help to maintain proper alignment of the piston during operation.
Piston is the device with a cup like shape that fit completely in the Cylinder.
excessive piston to bore clearance means that the gap (tollerance) between your piston and the sidewall of your cylinder/block is too large. usually will cause blow-by. the burning of oil, and dark exhaust smoke. also may cause the engine to have a weak compression stroke
A cylinder is the central working part of a reciprocating engine, the space in which a piston travels.
