Tyhjäajoa
Tyhjäajoa, often translated as "empty run" or "idle running," refers to the operation of an engine without it being connected to a load or performing any useful work. This can occur in various contexts, such as vehicles, industrial machinery, or generators. When an engine is running in tyhjäajoa, it consumes fuel and produces emissions, but its output is not being utilized.
In automotive applications, tyhjäajoa is commonly observed when a vehicle is stationary with the engine running,
In industrial settings, tyhjäajoa might happen when machinery is powered on but not actively processing materials
