ABSTRACT:
A fuel oil treatment unit and associated method for removing undesirable contaminants from a fuel oil, such as diesel oil, being delivered to an associated engine, such as a vehicle diesel engine. The invention includes, inter alia, a unit for treating contaminant-containing fuel oil, comprising means for heating the fuel oil to a temperature sufficient to volatilize at least some of the contaminants and, also, means for filtering the so-heated fuel oil, to remove therefrom at least some of the remaining, unvolatilized contaminants. Optionally, the previously-heated and filtered fuel oil is passed to a temperature control means for maintaining or returning the temperature of the fuel oil to a desired level. The inventive fuel oil treatment unit can be used as an intelligent system capable of delivering the precise amount of fuel oil at the required temperature and viscosity, regardless of external influences from the environment or other influences resulting from the operational demands of an associated engine to which the treated fuel oil is subsequently delivered.
