Abstract
The present invention relates to diesel purifier that produces a fuel of high purity that meets the full ignition requirements at the combustion chamber of the engine. The purifier is shown in Fig 1 of the attached drawings. The above purification process depends on causing of some differences in the density of contaminants which contributes towards settling of heavy impurities and the light contaminants are separated by wire filter assembly.
Description
DIESEL FUEL PURIFIER
Background of the invention:
Diesel Fuel is used for operation of almost all types of light and heavy equipment including vehicles, road construction equipment, tractors, farming equipment, metallurgy equipment, oil pro:~pecting equipment, electrical generators, trains, boats, ships, and military equipment, etc. Diesel contamination is one of the most factors that have an adverse effect on engine performance. For that specific reascan, primary filters are used for solid waste as well as secondary filters for the fine contaminants, and traps may be used for separation of water from the fuel. I-iowever, these filters are still ineffective and cannot cope with the frequE:nt contamination of the fuel.
Such filters and traps may be the only solution available at present for purification of the diesel fuel, but the problem about such devices is that they have to be periodically replaced and need periodical maintenance.
These conventional filters and water traps are capable to a certain extent to produce relatively clean fuel free from water and contaminants, but still they may be not able to remove the solid waste of less than ~ micron, and wax build-up especially during cold weather, which in most cases causes a total or partial blockage of such filters, which interferes with the fuel flow and ultimately negatively reflected on the engine itself due to lack of proper combustion.
To cope with this problem, the diesel engine employs electrical heating elements inside the combustion chamber for heating of air prior to starting of the engine, and another heating element is used in the purifier to improve fuel and generate load currents that contribute towards precipitation and separation of contaminants and eliminate wax build-up, which is positively reflected on ignition process and performance of the engine.

Using a purifier according to the invention will result in many advantages including for example:
1- Reduces carbon black to minimum thanks to full fuel combustion.
2- Protects the sensitive parts of the fuel system including injectors,
5 injection devices, thanks to improvement of the warm fuel lubrication characteristics (which is optimum at 36°C).
3- It eliminates build-up of sulphuric acid thanks to separation of water from the fuel.
Figure (4) shows the best place for installation of the unit, which is the fuel supply line, and after the main fuel tank which allows direct flow to the purifier.
Fuel is totally purified in the subject matter unit, fuel flows into the unit through the inlet (5) then down to the conical part (4) where it is affected by the heating element (10) which generates load currents due to fluctuation of temperature, which consequently affect the density of solid waste and fuel, which contributes towards settling of water and solid waste at the bottom, nearby the drain valve (13). Warm fuel is directed to the wire filters (7), which separate light contaminants, and fuel continue: to flaw towards the outlet (8) where a final filtration takes place through filter (22), which is fixed at the unit outlet. The result is a pure fuel free from water and contaminants.
The above purification process depends on causing of some differences in the density of contaminants which contributes towards settling of heavy impurities and the light contaminants are separated by the wire filter assembly. Such difference in density is created by heating of fuel at a confined area at the lower part of the unit. Once the appropriate temperature is reached, heavy contaminants and water precipitate, warm fuel flows towards the outlet through the wire filters that separate light contaminants.
Separated contaminants build-up at the bottom of the unit close to drain valve (13) where they accumulate up to certain level which is detected by sensor
