One of the parts in the piston are the piston head,
A bent engine piston is a reference to the piston rod. The piston cannot be bent, but the piston rod can be bent.
The piston rings create a seal between the piston and the cylinder wall.
There is the penis, the testicles, the scrotum, the prostate, the sperm duct etc.
A piston seal is a gasket designed to keep fluid from leaking around the piston. Piston seals are commonly used in brake calipers.
The piston doesn't twist it's way out. There is a ratchet screw adjustment that takes up the slack behind the piston. Screwing the piston back in resets the adjustment.
It is a spring metal sleeve that goes over a piston to compress the rings so that the piston can be install in the motor. It tightens down on the piston, forcing the rings into the grooves in the piston then you tap it into the cylinder.
It connects the piston to whatever the design calls for the piston to push or pull on. In a combustion engine, the piston rod connects the piston to the crankshaft, turning linear reciprocating motion into rotary motion.
A piston rod connects the piston to the crankshaft in an engine, transmitting the force from the expanding gas to the crankshaft to generate motion. A connecting rod connects the piston to the crankshaft, converting the linear motion of the piston into rotational motion to drive the crankshaft. In summary, the piston rod is part of the piston assembly, while the connecting rod is part of the crankshaft assembly in an engine.
A larger piston skirt to cylinder wall contact raises piston cooling. With turbo motors, they have piston oilers, they spray oil on the underside of the pistons, cooling the piston /crown.
