pistons

Reciprocating engine components

Pistons are cylindrical components that move back and forth inside a tube, typically to transfer force in an engine or pump.

In internal combustion engines, pistons convert the explosive force of burning fuel into the rotating motion that powers a vehicle.

Hydraulic systems use pistons to transmit pressure through fluid.

The word often appears in discussions of engine performance: The mechanic said one of the pistons was cracked.

Pistons is also the name of the Detroit NBA basketball team.
