Abstract

Owing to limitations in the transport and storage process of diesel, fuel is exposed to contamination with solids, such as rusting, and with liquids, mainly water in condensed and emulsified form. In addition to causing environmental problems, these contaminations affect the efficiency of the combustion and also decrease the useful life of the injection and explosion system, such as the injection pump, fuel injectors and combustion chamber. After 30 years studying the phenomenon, a filtering system capable of keeping back the water mixed in with the fuel was developed and patented. The separation principle takes advantage of the bipolar characteristic of water molecules using a chemically ionized filtering element. In its first stage, the objective of the research, based on the patented filtering technology, is to prove that the filtering element bathed in the selected chemical produces the desired effects of separation of solid particles and liquids (water) from the diesel oil, in an environment that simulates the discharge and the pressure of a working diesel engine. For this purpose, controlled tests will be carried out in purifiers constructed in the laboratory, using commercially available materials, without legal and environmental restrictions and at a market compatible cost.
