crankpins

Example:The mechanic is inspecting the connecting rod assembly for wear and tear.

Definition:A component of an engine that transfers force from the pistons to the crankshaft, converting the up-and-down motion (piston movement) to rotational motion needed by the engine for power output.

Example:The crankshaft is the backbone of the engine, around which the pistons and crankpins rotate.

Definition:A shaft which converts reciprocating forces into rotational motion, such as in internal combustion engines or steam engines.

Example:The piston travels through its compression and power strokes along with the crankpin.

Definition:A component of an engine that moves up and down inside a cylinder, compressing the air-fuel mixture and then moving it downwards to create a power stroke.
