piston
의미: A cylindrical component that moves up and down inside a cylinder in an engine or pump, transferring force between the expanding gas and the crankshaft.
Pistons are central to the operation of internal combustion engines, where they convert the explosive force of burning fuel into the rotational motion that drives a vehicle. Most car engines have four, six, or eight pistons. Pistons are also found in hydraulic cylinders, compressors, and pneumatic systems. The phrase 'firing on all pistons' (or 'cylinders') is an idiom meaning operating at full efficiency.
