ottosäiliö
An ottosäiliö, often translated as an Otto fuel tank or Otto cycle engine fuel tank, refers to the fuel tank specifically designed for use with an Otto cycle internal combustion engine. The Otto cycle is the thermodynamic cycle that describes the functioning of a typical spark-ignition piston engine. Therefore, an ottosäiliö is a container that stores the volatile fuel, typically gasoline or petrol, that powers such engines.
These fuel tanks are constructed from materials that are resistant to the fuel they contain, commonly steel
