Insugning

Insugning is a Swedish noun meaning the act of drawing something into a system or space by suction or intake. It derives from the verb suga in, meaning “to suck in.” The term is used across technical, industrial, and everyday language to describe processes in which a substance—typically air, gas, or liquid—is drawn into a vessel, pipe, engine, or organism.

In engineering and industry, insugning commonly refers to the engine induction process. The insugningssystem, including the air intake, throttle body, and intake manifold, controls how air is drawn into the cylinders during the intake stroke and how it mixes with fuel. In older or carbureted engines, insugning also described the delivery of the fuel–air mixture to the cylinders.

In building services and manufacturing, insugning describes air or gas being drawn into a ventilation or processing system, such as outdoor air entering a duct via dampers or fans, or gases being drawn away from a controlled space by exhaust systems.

In medical and physiological contexts, insugning may refer to the act of drawing air into the respiratory tract during inhalation, or more generally to suction-related procedures in specific technical descriptions. The exact meaning depends on context and terminology used by practitioners, and in non-Scandinavian texts the term may be less common or replaced by more specific terms such as inhalation, aspiration, or suction.

Overall, insugning is a versatile term for describing intake or suction processes across several fields, with the precise sense shaped by its domain of use.
