The Info List - Bore (engine)


--- Advertisement ---



The bore or cylinder bore is a part of a piston engine. The bore also represents the size, in terms of diameter, of the cylinder in which a piston travels. The value of a cylinders bore, and stroke, is used to establish the displacement of an engine.[1] The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons.
