choke-ground cylinder
A cylinder of a reciprocating engine ground in such a way that its diameter at the top of the barrel is slightly smaller than the diameter in the center of the barrel.
The large mass of metal in the cylinder head absorbs enough heat to cause the top end of the barrel to expand enough more than the remainder of the barrel that, at the normal operating temperature, the diameter of choke-ground cylinders becomes uniform throughout.
