摘要

Conditioning of petrol - based fuel prior to consumption is effected by storing a bulk quantity in a pressure vessel (13) and continuously extracting and returning a portion of that bulk quantity via a treatment conduit (18) which is heated along part of its length (19). The pressure vessel (13) is essentially unheated. Conditioned fuel is expelled from the pressure vessel (13) for consumption via a control valve (16), the pressure arising from the circulation and the condensation of heated vapours occurring within the vessel (13) from the fuel returning from the treatment conduit (18).
