täyttöaukon

Täyttöaukko is a Finnish term that translates to "filling opening" or "filler neck." It refers to a designated point where a substance is introduced into a container, system, or device. The specific nature of the täyttöaukko depends heavily on its application.

In the context of vehicles, a täyttöaukko is most commonly associated with the fuel filler neck, where gasoline or diesel fuel is poured into the fuel tank. These are typically covered by a cap or flap to prevent contamination and fuel evaporation. Other täyttöaukko examples in vehicles include those for engine oil, coolant, windshield washer fluid, and brake fluid.

Beyond automotive uses, täyttöaukko can be found in various industrial and domestic settings. For instance, a täyttöaukko might be present on a water heater for refilling purposes, on a swimming pool for adding chemicals or water, or on industrial tanks for storing liquids or gases. The design of a täyttöaukko ensures safe and efficient introduction of the substance, often incorporating features like seals, filters, or specific nozzle compatibility. The term emphasizes the function of access for filling.
