luftinnsprøyting

Luftinnsprøyting, often translated as air injection or air assist, is a process used in various applications to improve efficiency and performance. In the context of combustion engines, it refers to the introduction of air into the exhaust system. This secondary air injection helps to oxidize unburned fuel that would otherwise be expelled as emissions, thereby reducing pollution. This system is typically controlled by a pump and a one-way valve to prevent exhaust gases from entering the pump.

Beyond emissions control, luftinnsprøyting plays a role in some industrial processes. For instance, in cutting and welding, compressed air is often injected to cool the workpiece and remove molten material, leading to cleaner cuts and more precise welds. Similarly, in certain manufacturing techniques, air injection can be used to atomize liquids, creating finer sprays for coating or spraying applications. The principle remains consistent: introducing air to facilitate a process, whether it's combustion, material removal, or atomization. The specific design and implementation of luftinnsprøyting systems vary widely depending on the intended application, but the core function of introducing air for a beneficial effect is the common thread.
