wydechowe

Wydechowe is a Polish adjective formed from the noun wydech (exhalation, exhaust) with the suffix -owy, used to describe things related to exhalation or exhaust gases. In everyday language the term is most often encountered in two domains: automotive engineering and physiology.

In automotive engineering, wydechowy refers to the exhaust system, which channels exhaust gases from the engine to the outside world. The system wydechowy includes components such as kolektor wydechowy (exhaust manifold), rura wydechowa (exhaust pipe), tłumik (muffler), katalizator (catalytic converter), and often a diesel particulate filter or other emission-control devices, as well as sensors like czujnik tlenu (lambda sensor). The primary purposes are to remove spent exhaust gases, reduce noise, and limit emissions. Modern systems are designed to meet environmental regulations and may include materials like stainless steel and features such as resonators.

In physiology, wydechowy describes aspects of exhalation. The expiratory phase of respiration is called faza wydechowa; structures and muscles involved in expiration, such as mięśnie wydechowe, assist in expelling air from the lungs. The term may also appear in phrases describing airway segments or disease processes affecting exhalation.

Etymology: derived from oddech (breath) with the prefix wy-, indicating outward or outward release; the form wydechowy is common in technical and scientific Polish.
