piston

The piston (Breton: pistoñ, English phonetic "pist-on") is a type of oboe invented by Breton musician, teacher, and luthier Youenn Le Bihan in 1983.

Examples from Collins dictionaries As the pistons move up and down, the crank is rotated. The reciprocating pistons are connected to the crankshaft by connecting rods. The piston reaches bottom dead center and then begins to travel upward.

A piston is a cylinder or metal disk that is part of an engine. Pistons slide up and down inside tubes and cause various parts of the engine to move. French Translation of. 'piston' 'creature feature'

The word itself comes from the piston's repetitive movement - it shares a root meaning of "to pound" with pestle, the tool used for pounding and grinding spices. "Piston." Vocabulary.com Dictionary, Vocabulary.com, https://www.vocabulary.com/dictionary/piston. Accessed 26 Oct. 2023.

The pistoñ is a contemporary development of the hautbois, classical and/or baroque oboe, influenced by the bombard or talabard, the traditional double reed instrument of Brittany. It is typically rooted in the key of D and features post-mounted simple system key-work to expand its range.

As a component of combustion engines, the piston converts the energy released during combustion into a mechanical action and transfers it to the crankshaft in the form of a torsional force via the piston pin and the connecting rod.

Types of Pistons

• There are three types of pistons, each named for its shape: flat top, dome, and dish.
• As simple as it sounds, a flat-top piston has a flat top.
• Dish pistons present the least problems for engineers.
• Opposite in concept to the dish pistons, these bubble in in the middle like the top of a stadium.

As the crank rotates, the piston moves up and down in a linear reciprocating motion. A crank and piston system transforms rotational motion into linear motion. The linear motion can be vertical or horizontal (or in another direction), depending upon the orientation of the guide.

As the engine reaches operating temperature, the piston pin bore area expands more than other thinner areas of the piston. At operating temperature, the piston shape becomes a circular shape, which matches the cylinder bore for improved sealing and combustion efficiency.

Pistons form a combustion seal and transmit forces from combustion to the connecting rods. Pistons are made from either a low carbon steels or aluminum alloys.
