Filters coarse and fine fuel purification

Gasoline is obtained from oil with secondary processing, then transported on gas stations. With these manipulations, impurities in gasoline appear, which we buy with you. In addition to technical impurities, it can also get into fuel dirt, dust particles and much more, we also note that the composition of gasoline includes water, which is also an admixture, in a small amount: 60-100 grams. on ton of gasoline. Another feature of gasoline is a mix form that directly depends on the contact with air, that is,: in the gas tank, the mixing is quickly quick to harm your engine, as it can be postponed on the rods of ink valves. How to get rid of it all?

Two main filters: thin and rough cleaning

Get rid of them quite simple, it is enough to take advantage of good filters, which will be discussed in this article. There are two main stages of fuel purification, such as: primary and finishing stage, respectively two filters: coarse and fine fuel purification. Between them there is a difference in the location, such as the main and submersible and sizes of the particles that they skip. Coarse filter passes particles with dimensions less than 0.1 mm, and thin - up to 15 microns or 0.015 mm.

varieties of filters using the filter element

There are several different filters: slotted, mesh, felt, etc. Briefly talk about them.

The mesh filter uses the grids as a filter element, so fuel, passing through the grid, is cleaned.

The slit filter uses longitudinal and annular gap under pressure, so fuel, passing through such a system, it turns out purified.

Felt filters are used as a filter element felt. Felt - dense material, passing through the layers, fuel is cleaned from harmful impurities.

What do you need a filter

As mentioned earlier, impurities in gasoline are a lot and this in high-quality gasoline, you can also buy both poor-quality, in which it can be contained much more impurities that increases the risk for the engine.

To secure your motor from the destructive effect of impurities, you need a cleansing fuel filter. It will clean the fuel from impurities, and your engine will work better, as well as longer.

Filter-sump rough fuel purification

Picture 1.
As it was said earlier, fuel filtering occurs in two stages, rough cleaning is the first, which can remove large particles of dirt, impurities and water. Filters are separated by location: trunk and submersible. The first are located directly in the fuel line, and the second - in the tank, next to the pump.

principle of operation of a coarse filter-sump

Figure 2.
Figure 2 (a) shows a coarse filter:

  1. Glass-sump.
  2. Spring.
  3. Union.
  4. Frame.
  5. Bolt.
  6. Union.
  7. Filtering element.
  8. Holes.
  9. Plates.
  10. Rack.
  11. Bolt.

This settling tank is installed on gas and zil cars, and it is a submersible slot filter, as it is installed between the fuel tank and the pump and has a slit filter element. With the help of bolts 5 and 11, a glass of 1 is attached, the filter element 7 holds with a spring 2. The fuel, passing through the fitting 6, enters the glass 1, in which the filter element is located, water remains at the bottom of the glass, and gasoline, passing under pressure through The filtering element, namely through the holes 8, is cleared of dirt and other impurities, it leaves purified through the fitting 3.
How to find out what the filter is clogged?
There are several signs:

  1. Engine power drops.
  2. The engine began to stall often.
  3. The car pulls when traveling.

Tip: As soon as you make sure that the filter clogged, change it, and do not try to wash with water. Dirt is very high in the filter element and do not rinse it with water. This is if the filter is felt, but if the mesh, then, on the contrary, flushing with a special mixture, purified from contamination. It is best to install which one you have a filter, and from here to come in solving the problem.

Filter of fine cleaning

As mentioned earlier in this article, even very small impurities can significantly reduce the duration of the engine. That is why the fuel purification filter is needed, which is the second and final fuel purification step, because the previous filter cleaned fuel from water and large impurities. Filter felt, as it has a corresponding filter element.

how the fountain cleaning filter is arranged

  5. Bracket.
  6. Screw.

With the help of a bracket 16 and nut 17, a glass-sump 13 is attached to the housing 12. The fuel, passing through the fitting, cleaning with the help of the filter element, it passes on, is already straight into the engine.

Varieties of fuel purification filter

fine Cleaning Filter Uncovered

Figure 5.

This filter does not understand, which is why after it is clogged it will have to throw it out. It is because of its disposable the price of it somewhat less than the following type of fuel purification filter. The cheapness of this filter is its main advantage, they do not differ in quality. Such a filter is very suitable for the car, which you are going to sell soon, in order not to spend money on the purchase of a collapsible filter.

Filter thin cleaning collapsible

Figure 6.

This type of filter can be easily disassembled to throw out the filtering element if it clogged, insert a new one, it is for this reason that this filter will cost more than the previous one, but in the future it will pay off in full. Such a filter should be purchased for cars that intend to exploit on which more than 30 thousand km are going to drive. 30 thousand km - this is exactly what a car should drive, after which the manufacturers of filters recommend to change it (filter). Tip: Before removing the filter, make sure that there is some capacity to drain fuel residues, then substitute under the hoses and boldly remove the filter.

filter of fine cleaning with transparent housing

Figure 7.

This type of filters should be allocated for their main feature - the transparency of the case. It is worth it to clog, so it will be easy to find out. For example, if the filter is filled with halfway, the filter works absolutely normal, if completely - the filter clogged, it must be changed. Also, this filter can serve as an indicator of a good tightness of the fuel supply system: if air bubbles are present in the filter, it means that the system is violated.

Fuel purification filters for diesel engine

The composition of diesel fuel includes paraffin, which at low temperatures will crystallize on the filtering element, intensively clogging it, thereby outlining the filter.

To avoid this destructive effect, the heating element is added to the filter device, which is why these filters should be highlighted among all. The heating element does not crystallize the paraffin on the filter element, which extends the service life of the filter itself. If you are the owner of such a car, make sure that the heating element is, of course, if you have enough cold winters.

This video illustrates the filter action, namely: it is clear that the fuel intentionally added a lot of impurities, for example "Coca-Cola", and joined the vessel with gasoline, which with impurities, with a filter, and using the hose and pump system, pumped gasoline in the second vessel. After filtering, it can be seen that the filter coped with the task and cleaned the fuel. So: in the right volume, filled fuel, the vessel was added impurities that change the color of the fuel. With the help of the entire design, the fuel is pumped into the left vessel. As can be seen in the video, the filter cleaned the fuel and gasoline from impurities in the left vessel transparent.

Conclusion

Let's summarize: it is necessary to put the filters to protect your own engine, it is also worth watching the filter tornness to change it on time and not kill the motor. The filter replacement is made approximately at 25-20 thousand km of the car's mileage on one filter. I hope that after reading the article, you will not be mistaken in the fact that there may be lucky without the filter. "

    SEPAR-2000 fuel filters
    The filter is fully coping with the main problem of using a diesel engine, that is, 100% separates water and other mechanical impurities. These substances are regularly formed in the fuel tank.
    Such a filter is able to ensure reliable protection of all elements of the fuel system of diesel engines, including expensive. The life of the nozzles, the fuel pump, the fuel lines increases significantly. On average four to five times. Perfect operational characteristics.

    The design is compact enough. Another advantage is the economic benefit reaching 300-500%. This is due to the inexpensive cost of filters, as well as at low costs of their installation and maintenance. Systems can be installed on trucks, agricultural equipment, construction and road equipment.
