71Flywheel — [ Leonardo da Vinci] A flywheel is a mechanical device with significant moment of inertia used as a storage device for rotational energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a… …
72Stroke ratio — In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term which is used to describe the ratio between the diameter of the cylinder bore and the length of the piston stroke within its… …
73Linear alternator — A linear alternator is essentially a linear motor used as an electrical generator. (An alternator is a type of alternating current (AC) electrical generator.) The devices are often physically equivalent. The principal difference is in how they… …
74Bore (engine) — Bore is the diameter measurement of the cylinders in a piston engine. Engine displacement is calculated by: The term bore can also be applied to the bore of a locomotive cylinder. See also Stroke (engine) Compression ratio Cylinder head porting… …
