Description

Diesel Fuel Purifier {DIESEL FUEL PURIFIER}

Diesel fuels are used for the operation of almost all types of light and heavy equipment, including vehicles, road construction equipment, tractors, agricultural equipment, metallurgical equipment, oil drilling equipment, electric generators, trains, boats, ships and military equipment. The diesel fuel contaminants are one of the most important factors that adversely affect engine performance. For this particular reason, the main filter is used not only for solid waste, but also as a secondary filter for fine contaminants, and traps can be used for the separation of water from fuel. However, these filters are still inefficient and cannot cope with frequent contamination of the fuel.

The filter and trap described above may be the only solution currently available for the purification of diesel fuel, but the problem with the device is that the device has to be replaced periodically and requires periodic maintenance.

While conventional filters and water traps can produce a relatively clean fuel free of water and contaminants, they are unable to remove solid waste below 5 microns, and waxes accumulate especially during cold weather, most of which In the case of this, this results in full or partial shut-off of the filter, which impedes fuel flow and ultimately negatively affects the engine itself because of the lack of adequate combustion.

To overcome this problem, diesel engines use electrical heating elements inside the combustion chamber to heat the air prior to engine start-up, while other heating elements improve load and contribute to the separation and settling of contaminants. It is used in purifiers to generate currents and to prevent wax buildup that positively affects the ignition process and engine performance.

The present invention addresses the problems associated with diesel fuel contaminants, minimizes pollution and repair, and maximizes engine performance because of the relatively complete combustion inside the combustion chamber.

The present invention also aims to produce highly clean fuels and to produce available fuel purifiers that are relatively maintenance free compared to conventional filters and traps currently in use.

The present invention is mainly designed for cold areas since it does not require two heating elements (inside the combustion chamber and in the fuel filter system).

According to a first embodiment of the present invention, in a diesel fuel purifier unit including a purification chamber surrounded by an outer body, the purification chamber is surrounded by a wire filter. It has a barrier with cylindrical and conical sections, so that fuel flows from the diesel fuel purifier inlet through the pipe to the conical section, and the upper portion of the diesel fuel purifier has a relief valve, and The lower portion of the diesel fuel purifier has a heating element and a water sensor that can be connected to a sound and light indicator on a cabin dash board, and the bottom of the diesel fuel purifier has a A diesel fuel purification device is provided in which a drain valve and a filter are fixed to the outlet.

According to a second embodiment of the present invention, in the first embodiment, the outer body, the fuel inlet pipe, the cylindrical and the conical portion are made by forming a black steel sheet, and the upper and lower covers are molded. And a position for the relief valve, the heating member, the water cock and the drain valve are formed by a hydraulic device.

The present invention relates to a diesel fuel purification apparatus for producing a high clean fuel satisfying complete combustion conditions in a combustion chamber of an engine.

Any reference to a diesel fuel purifier or purifier should be understood to mean a preferred device according to the invention in this description.

The invention is explained in detail in the accompanying drawings, in which FIG. 1 is a longitudinal sectional view of a diesel fuel purification apparatus. The diesel fuel purification device mainly consists of a purification chamber 1 surrounded by the outer body 2 of the device, the purification chamber 1 being connected by a wire filter 7. The surrounding has a cylindrical tapered section 3 (shown in FIGS. 4A and 4B).

Fuel is discharged through a pipe (6) to a fuel inlet (5) and through the final filter (22) located immediately before the wire filter (7) and then to the outlet (8). To the conical part of FIG. 4 which is heated by a heating element 10 to an arbitrary temperature for heating it. The upper portion of the diesel fuel purification device includes a relief valve 9, and the lower portion of the diesel fuel purification device includes sound and light indicators on the heating element 10 and the vehicle dashboard. A water cock 11 is connected to the light indicators 12 and a drain valve 13 is provided at the bottom of the diesel fuel purifier.

The cylindrical body 2 and the fuel inlet pipe 6 and other cylindrical conical sections 3 and 4 are made of black steel sheet, upper and lower covers and the relief valve 9, the heating The holes and spaces for the member 10, the water cock 11 and the drain valve 13 are formed by a hydraulic device.

Once the cylindrical part is constructed and the valves are in place, the connecting part is ground, the device is cleaned by suitable solvents, and the tightness and leak test is performed at 7 bar for the device. Performed by using pressurized air, the passed device is then coated with a suitable paint, and when used for sea, the device is coated with marine grade moisture and corrosion resistant paint.

The relief valve 9, the heating member 10, the drain valve 13 and the water cock 11 are all fixed by clamps. In order to prevent any leakage, gaskets (not shown) are used for the installation of these valves. These parts can also be installed by pressing or riveting or by a commonly accepted method.

2 is a diagram showing in detail a method of installing a diesel fuel purification device in a fuel system of a vehicle. Fuel from the fuel tank 14 is connected to the sound and light indicator at the device inlet 5, heating element 10 and dash 12 having the relief valve 9 in the direction of the arrow 15. (11) and the drain valve (13). The device is secured by a band 16.

The diesel fuel is purified in the apparatus and the pure diesel fuel goes from the outlet 8 to the main filter 17, then to the injection pump 18 and then to the engine (not shown in the figure).

3 shows how the purification device is installed in a vehicle. The purifying device is fixed by a steel clamp 16 which is fixed by a screw 19 to the U-shaped bracket 20 in the vehicle frame 21.

Using the purifying device according to the invention generates a number of advantages, including the following examples:

1. Reduce carbon black to a minimum due to complete combustion.

2. Because of the heated fuel lubrication properties (optimum at 36 ° C), it protects sensitive components of the fuel system including injectors and injection devices.

3. Prevents the accumulation of sulfuric acid due to the separation of water from the fuel.

4 shows an optimal position for the installation of the device, which is the main fuel tank which can be flowed directly into the fuel supply line and then to the purification device.

The fuel is completely purged in the purifier and contributes to the precipitation of water and solid waste in the interior of the purifier through the inlet 5, near the bottom, the drain valve 13, thus the density of the solid waste and the fuel Flows below the conical part 4, which is affected by a heating element which generates a load current due to the temperature fluctuations, which affects. The heated fuel continues to flow to the wire filter 7 which separates light contaminants, and the fuel continues to the outlet 8 for final filtration through a filter 22 fixed to the purifier outlet. Thus, pure fuel free of water and pollutants is produced.

The above purification process relies on the occurrence of significant density differences in the contaminants that contribute to the precipitation of heavy impurities and light contaminants are separated by the wire filter assembly. Said density difference is caused by the heating of the fuel in the limited region of the lower part of the purification apparatus. When the appropriate temperature is reached, heavy contaminants and water condense and warm fuel flows to the outlet through a wire filter separating light contaminants. The separated contaminants accumulated at the bottom of the purifying device are blocked by the drain valve 13 and accumulated to an arbitrary level detected by the sensor, at which point the sensor has a warning light indicating when to discharge the contaminants and Start the alarm system.

Contaminants are easily discharged by opening the upper relief valve 9 and the lower drain valve 13. When the discharge is completed, the relief valve and the drain valve are tightly closed.

The discharge device can be modified to operate automatically by replacing the valve with a solenoid valve.

It will be appreciated that many variations and modifications can be made to the invention without affecting the principal concept of the invention.

Throughout the specification, unless the description requires another, a change such as the word "comprise" or "comprising" refers to the inclusion of the described complete or group of other completes and any other complete or complete You will understand that it does not exclude groups of people.

The present invention can minimize contamination and repair to a minimum, and maximize engine performance because of the relatively complete combustion inside the combustion chamber.

In addition, the present invention produces a fuel of high cleanliness and can produce a fuel purifier that is relatively maintenance free compared to conventional filters and traps currently in use.
