Wikipedia
Crankshaft

A crankshaft—related to crank—is a mechanical part able to perform a conversion between reciprocating motion and rotational motion. In a reciprocating engine, it translates reciprocating motion of the piston into rotational motion; whereas in a reciprocating compressor, it converts the rotational motion into reciprocating motion. In order to do the conversion between two motions, the crankshaft has "crank throws" or " crankpins", additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach.

It is typically connected to a flywheel to reduce the pulsation characteristic of the four-stroke cycle, and sometimes a torsional or vibrational damper at the opposite end, to reduce the torsional vibrations often caused along the length of the crankshaft by the cylinders farthest from the output end acting on the torsional elasticity of the metal.

Standard forged pistons and connecting rods can't handle the kind of power you're going to be cranking out, so we've replaced them with super tough Venola forged blower pistons, Crower rods with big, heavy, stiff bolts, and a magnefluxed crankshaft.

These modified, Delux 30 Chevrolet pickups really packed a wallop he thought: Venola forged blower pistons, Crower rods, magnefluxed crankshaft, Paxton centrifugal supercharger forced induction system I A legacy of Fritz.

Power of explosion is exerted on piston and through connecting rod and crankshaft through transmission thence to rear wheels.

With their supporting frames, connecting rods, crankshafts, gimbels, and ancillary equipment, they take up most of the vessel's interior below this deck.

Each piston moves independently of the others, transferring the power generated by its vertical motion of two connecting rods, thence to a crankshaft.

The gas was ignited by the spark plugs and the explosion hit the cylinder head and the head was thrust down and that turned the crankshaft and the valves opened and closed and the cylinder heads kept going up and down and the crankshaft turned some more.
