tehokäyrä
Tehokäyrä is a Finnish term that translates to "efficiency curve" or "power curve." It is most commonly used in the context of engineering and performance analysis, particularly when discussing engines, machinery, or systems. A tehokäyrä graphically represents the relationship between a system's output (such as power or torque) and a relevant input variable, which is often speed (RPM) or load.
The curve typically shows how performance changes as the operating conditions are varied. For internal combustion
Beyond engines, the concept of a tehokäyrä can be applied to other systems where output efficiency is
