The Engine Cylinder Overbore (volume) calculator computes the total engine displacement of a combustion engine with cylinder overbores.
INSTRUCTIONS: Choose units (e.g. inches, mils, millimeters) and enter the following parameters:
Engine Overbore Volume (V): The Total Displacement with Overbore volume is returned in cubic inches. The volume can be automatically converted to other volume units (e.g. cubic centimeters) via the pull-down menu.
Overbore is the additional diameter added to a cylinder and is common in piston replacement. Note: overbore is often in the units of mils. 1 mil = 1/1000th of an inch. Engine displacement is the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead center (TDC) to bottom dead center (BDC). Engine displacement is determined from the bore and stroke of an engine's cylinders. The bore is the diameter of the circular chambers cut into the cylinder block. When calculating engine displacement for engine with an overbore, the overbore is added to the bore in the calculation.
Theis as follows:
`v = π⋅((b+oB)/2)^2⋅s⋅n`
