yläturboilman
Yläturboilman is a Finnish term that translates to "upper turbo air" or "overhead turbo air". It is a technical term used in the context of internal combustion engines, specifically those equipped with turbochargers. The term refers to the air that has been compressed by the turbocharger and is subsequently flowing into the engine's intake manifold and cylinders. This compressed air is denser than ambient air, meaning it contains more oxygen molecules within a given volume.
When a turbocharger spins, it forces more air into the engine than it would naturally draw in.
