Bore (engine)

Bore (engine)

Bore is the diameter measurement of the cylinders in a piston engine.

Engine displacement is calculated by:

\mbox{displacement} = {\pi\over 4} \times \mbox{bore}^2 \times \mbox{stroke} \times \mbox{number of cylinders}

The term "bore" can also be applied to the bore of a locomotive cylinder.
