Do I need to clean diesel fuel?
There are no differences of opinion here - it is necessary.
Moreover, contrary to popular belief, contaminated diesel fuel is not only a Ukrainian problem.
Water and particulate matter in diesel fuel quickly destroys expensive fuel equipment.
Low temperatures lead to crystallization of water, thickening and waxing of the fuel.
Standard fuel filters fail quite quickly, and are often expensive.
Exit - install additional system cleaning with inexpensive replaceable elements.
For cold working conditions - heated.
Terminology
When it comes to fuel purification devices, there are different terms - "filter", "separator", "filter-separator", "filter-moisture separator", etc.
Actually, modern systems cleaning diesel fuel often represent a combined device - a separator of moisture and large particles, combined with a fine (or not very fine) filter.
For example, the term "Diesel Fuel Filter / Water Separator" is used in the catalogs.
We have a similar term "Water Separator an Fuel Filter".
At the same time, in the descriptions the manufacturers themselves often use the term "filter" for brevity.
In Ukraine, such devices are often called simply "separators".
Selection criterion - fuel consumption
Optimum separator performance is achieved when operating conditions are matched specific engine separator performance.
One of critical characteristics is the recommended fuel consumption.
This is due to the fact that the efficiency of separation processes in many devices depends on the hydrodynamics of the flow, which, in turn, is determined by the flow rate.
In this regard, one cannot fail to mention one common phenomenon.
Domestic sellers of the popular separator often recommend this separator for installation on cars.
At the same time, the younger model in the line is designed for a flow rate of 300 l / h.
This is the fuel consumption of a supercar at 350 km / h.
Or a heavy truck, excavator or boat.
Concerning passenger cars, then if a jeep travels 100 km in an hour and consumes 20 liters of fuel, then the hourly consumption will be 20 liters - 15 times less than that of the smallest separator!
In this case, such a big difference is of fundamental importance.
The patented separation process is based on a centrifugal effect, which in turn is only achieved with a sufficient flow rate.
At a low flow rate at a large working section, the centrifugal effect will not be achieved, the fuel will simply drain into the sump.
Most of the water and impurities, of course, will settle naturally, but it will not be possible to achieve the maximum return from the centrifugal effect.
Accordingly, the load on the built-in filter will increase. fine cleaning.
Strong dependence of the degree of purification on the liquid consumption - common disadvantageinherent in centrifugal cleaning systems.
It is impossible to completely get rid of it, if only due to the fact that fuel consumption under different operating modes of the engine changes significantly.
But you should not aggravate it by using devices that are obviously unsuitable in terms of characteristics.
Therefore, it is necessary to choose a separator based, first of all, on the average fuel consumption in accordance with the manufacturer's recommendations.
Too small throughput separator leads to increased load on fuel pump, loss of power and other negative effects.
Too large - to unnecessary costs and, often, to a decrease in the cleaning efficiency.
As an additional criterion, you can focus on engine power - separator manufacturers often indicate this characteristic.
Heated and unheated
Even when using winter diesel fuel, there may be problems with starting the diesel engine during the cold season.
The reason is the natural thickening of the fuel, as well as paraffinization (formation of paraffin flocs) at low temperatures.
The solution to the problem is to use heated separators.
Heating is a heating elementbuilt into the separator body.
The heated version is significantly (50-100%) more expensive than the unheated version.
As a rule, you can use models of diesel fuel separators with a heater installed at the factory (in the designation such models have the letter H), or you can purchase a separator without a heater, and, if necessary, purchase and install it later.
When choosing an option with or without heating, you must first of all be guided by climatic conditions.
For northern regions, it is advisable to choose the heated option.
For regions where the thermometer is in winter time often keeps at around -10 ° C and below - heating is also desirable, but you need to pay attention to the features of operation.
If we are talking about commercial vehicles that are intensively used at any time of the year, heating is needed.
If winter operation is intermittent or absent, you can save money and not install heating.
As a last resort, if necessary, it can be installed later.
Filter element
For various working conditions, manufacturers suggest using different types filter elements differing in material and pore size.
Separators have 2, 10 and 30 microns.
U - 10, 30 and 60 microns (there is a mention that the Separ 2000 10 micron filter element is intended only for gasoline).
A 2 micron filter element is recommended for warm season products.
For cold weather - a 10 micron filter element (the designation of such an element contains the letter W - Winter).
For heavily contaminated fuels and outdated engines - 30 micron elements.
For separators, 30 micron filter elements can be used.
For heavily contaminated fuel - 60 micron metal mesh.
Of course, the smaller the pore size of the filter element, the better the fuel will be cleaned.
But there is also a downside to the coin.
A finer filter clogs faster, increasing the hydraulic resistance of the system.
In the cold season, even the permissible natural thickening of the fuel can lead to the impossibility of using a fine filter.
Therefore, it is necessary to choose the filter element as small as possible, but always taking into account the specific engine and operating conditions.
Modern precision fuel equipment, especially Common rail, is very sensitive to the quality of fuel, so you should not save on replaceable elements - repairs will be much more expensive.
With intensive engine operation, a vacuum gauge can be installed behind the filter to control the hydraulic resistance.
In this case, certain readings of the vacuum gauge will serve as a signal for replacing the filter.
Manufacturer's choice
To paraphrase the satirist, in most cases one can say: "all separators are equally useful." We are talking, of course, about well-known brands like,.
Almost every manufacturer has a patented technology in stock that allows to achieve almost 100% fuel purification from water and solid impurities.
This depressurizer is a cone on the surface of which separation occurs.
This is a passive cyclone - a spiral surface that separates light and heavy fuel fractions under the action of centrifugal force.
After the primary separation, the heavy fraction (water and solid particles) remains in the sump, while the light fraction (refined diesel fuel) rises to the fine filter, simultaneously getting rid of smaller water droplets and polluting particles.
Therefore, when choosing, for example, between and, it is enough to be guided by the performance characteristics of the devices, their dimensions, price and availability for purchase.
The result of similar devices will be approximately the same.
The following table may be helpful when choosing a separator:
| Application | BALDWIN DAHL (without heating) |
BALDWIN DAHL (heated) |
SEPAR 2000 (without heating) |
SEPAR 2000 (heated) |
| Consumption 75 l / h (cars, small diesels) |

There are not many ways to make a DIY diesel separator. In most cases, experts recommend choosing a suitable product on the market. This is due to the fact that this unit is aimed at cleaning the fuel from various impurities, which are present even in high-quality diesel fuel, albeit in smaller quantities. Failure to comply with the slightest technological subtleties in the manufacture of the device in question can lead to sad consequencesassociated with malfunction of the engine and its failure.
However, for modernization lovers vehicle with your own hand, nothing is forbidden. The element in question is no exception, only, it is necessary to approach the process with the awareness of all possible consequences and the presence of experience with the insides of the car's fuel system.
Purpose
How to make a separator for diesel fuel with your own hands, its purpose and installation methods, we will consider further. The functions performed by this unit are additional heating of the fuel system and filtration of diesel fuel before it enters the combustion chamber. Modern separator type filters are completed with all additional elements mounted in one block.
A properly installed device is able to remove up to 90% of mechanical impurities and water from diesel fuel. Additional heating helps to prevent liquid crystallization, especially in winter. The cleaning procedure is as follows:
- The emulsion is cleaned due to the centrifugal force of the centrifuge. The sediment accumulates at the bottom of a special sump;
- Separation of impurities by fractional indicators is performed;
- The final stage of filtration makes it possible to obtain clean fuel at the outlet after passing it through a corrugated cartridge.
Making a separator from improvised means
One frosty morning, a car with a diesel unit stopped responding to starting. Clearing the snow didn't help. Initially, the fuel filter was examined for damage. Since, in the case under consideration, it is practically new, the reason should be sought in another node. It is noteworthy that when gas was added, the reaction of the car's engine became chaotic and uncontrollable.
A way out of this situation was found in the arrangement of a homemade separator with a heater. Further manipulations consisted of adding fuel to the main line. This procedure not difficult to produce, since pressure is created in the return line, which contributes to filling the main part of the line. The essence of the additional element is the possibility of heating fuel by the flow method.
This requires a couple of meters of rubber hose, a “ruff” connection and fixing clamps. The installation of a homemade separator with a heating element consists in the additional installation of a couple of meters of rubber hose, fixed with clamps, and a VAZ aluminum fuel line.
The essence of the design is as follows:
- The conductive fuel system of aluminum composition must be bent in such a way that it is tightly pressed against the exhaust manifold of the exhaust pipe;
- These elements warm up at a fast pace and contribute to the heating of the fuel and parts through which it circulates;
- Additionally, the unit can be equipped with a heater, which will create additional thermal insulation.
Hand-made installation of factory units
The separator device for diesel power units is mounted taking into account the supply of the working mixture between the tank and fuel filter... If the upgrade does not contradict the manufacturer's recommendations, you can remove the standard coarse filter from the system. In subsequent operation, its functions will be performed by an element that comes complete with a separator block.
As a rule, the node in question does not require significant additions. All the main parts, from the separator device, fasteners, filters and connections, go in one unit, which makes it possible to intelligently and practically place the unit in the system. Some of the nuances of the hand-made installation of the element in question consist in the correct placement of the supply pump, which should be on the same level with the separator block.
Some useful tips help modernize diesel engine equipping it with the element under consideration. How to make a separator for diesel fuel with your own hands is quite obvious. However, this delicate work will require certain knowledge and practical skills.
Diesel fuel, which is sold at gas stations in our country, contains a lot of heavy and harmful impurities for the engine. Also, diesel fuel must contain paraffin particles and water. Driving on such fuel for a long time will result in serious deterioration of engine performance. Each owner of a diesel engine faced difficulties when starting the engine, a drop in power in winter. The water contained in diesel fuel will turn into crystals in winter. The fuel will be less liquid. These changes negatively affect the quality of work power unit and reduce its resource.
To protect the engine from low-quality fuel, it is worth using a diesel fuel filter separator (there is a photo in our article). In Russian conditions, they are simply necessary. Coarse and fine filters are not enough. In addition, they often fail, and their price is quite high.
How does the filter separator work?
This element represents combined system... So, one part serves as a sump. Here solids gradually accumulate at the bottom. In the second part, it retains water, paraffins and other substances dissolved in diesel fuel. Additionally, the housing can have a heating system, as well as elements for mechanical cleaning of diesel fuel.
Functions and principle of operation
How does this element work? Most motorists often confuse mechanical separation equipment with sedimentation filters or coarse cleaning mechanisms. The filter separator for diesel fuel is mechanically cleaned. It removes various foreign particles from the fuel and protects the fuel system from the accumulation of dirt.
Among the main tasks that these products perform, two can be distinguished:
- The process of flaw detection of impurities.
- Allocation of water.
These filters can remove up to 99% of water and up to 95% of mechanical particles from a diesel engine. And this despite the fact that the fuel has a very high concentration of both impurities. If a heated diesel fuel filter separator is used, this prevents water crystallization processes, as well as diesel fuel waxing at low temperatures air.
The fuel flows according to a certain pattern. So, at the first stage, the emulsion is processed by means of centrifugal cleaning. For this, the device is equipped with a stationary centrifuge. At this stage, solids and water enter the settling tank.
Further, intermediate coalescing processes take place by changing the flow directions. What is the essence of this cleaning step? Even smaller particles of impurities are separated from the fuel. In the final phase, the fuel is cleaned of microscopic particles using a cartridge - a filter element. Then diesel fuel is fed to the pump.
A heating element can also be used in the device. It promotes successful winter start-ups. So, paraffins will not crystallize, but will simply dissolve. Due to this, the components of the fuel system of a diesel engine will work for a long time and properly, in conditions that are comfortable for them. On cars with such a system, drivers did not observe problems with starting in cold weather.
Filter elements: device and features
Next, consider what constitutes a filter design. Diesel fuel separators are equipped with a cartridge. This element is an ordinary plate, but small holes are made in it. The smaller their size, the more efficient the fuel cleaning will be. However, when choosing, you should not chase the numbers. The filter element with the smallest hole diameter - only 2 µm - clogs up very quickly. And due to the blockage, the hydraulic resistance of the system increases. The motor will start unstable.
Filters with large openings (from 30 microns and more) are designed for cars that are equipped with old motors. Such a fine diesel fuel filter separator can be used to work with very dirty diesel fuel. A device of this type will last longer and will not create any problems with the fuel supply to the owner. Naturally, after a while it will have to be replaced.
Experts recommend choosing a filter that will have the smallest possible hole size, but it is important to take into account the type of engine and its operating conditions. For example, modern Common Rail fuel systems are very demanding on fuel quality. Therefore, with such motors, you should not save on filters.
How to choose
In order for the Diesel Filter Separator to perform optimally, there are several key factors to consider. So, experts recommend paying attention to the average fuel consumption, supply voltage and heater power. Also, the device can be equipped with a water sensor and a heating control system. Additionally, the design has an additional pump for pumping diesel fuel. And, finally, when choosing, the fineness of cleaning and overall dimensions are important.
Naturally, a large number additional options make the filter separator for diesel fuel more expensive. However, these same options make it easier to service the product. In stores, sellers often try to sell expensive device and motivate this by the fact that the model is different high quality work. At the same time, the seller does not even try to find out about the fuel consumption of a particular car. But when the fuel consumption is small, and the working section is large, then the necessary centrifugal effect will not be created. As a result, an expensive device will simply turn into an ordinary sump.
Filter separators in Russia: models, prices
Over the past 10 years, Russian stores have significantly expanded the range of parts for cleaning heavy fuels. The modern market offers a lot of products renowned manufacturers... There are plenty to choose from.
It is necessary to replace the fact that even the domestic auto industry has begun to introduce devices for separator cleaning of fuel. For example, now KamAZ is installing a filter separator for diesel fuel right at the plant. These are the Separ-2000 model and Mann-Filter products.
Consider several models that are quite popular among motorists, which have long been able to prove their high efficiency on different cars.
"Separ-2000" with heating
These are the products of the German manufacturer Willibrord Lösing. These filters have long been known and used professional drivers... Separ-2000 is fundamentally new system centrifugal cleaning. Processing is carried out in several stages. The filter is suitable for use on a wide variety of automotive engineering... Most car manufacturers already install this equipment as standard filters.
This separator ensures that the fuel is cleaned as much as possible from dirt, water and wax. The cleaning process is carried out in three stages. If this device is installed, the service life of the equipment in the diesel fuel system will increase 4-5 times. At the same time, equipment repair and maintenance costs are reduced.
Features of "Separ-2000"
The algorithm of action is based on the principle of operation of the centrifuge, although it is not in the filter device. All particles heavier than diesel fuel are released from the liquid at different stages of the purification process and accumulate in the sump. The filter contains elements with mesh sizes of 2, 10 and 30 microns. One of the significant advantages of this element is the self-cleaning function. The element is well cleaned of water and dirt.
Many car owners of domestic and imported cars choose the Separ-2000 heated diesel fuel filter separator. Reviews about them are more than positive. The cleaning quality is really good, as motorists say. The heating function is very helpful in winter.
Stanadyne
This company is from the USA. It manufactures various products for automobiles.
The assortment also includes filter separators. Thus, the company offers the Fuel-Manager system. It is a modular solution that includes a water separator, a real innovation
Features:
The Stanadyne diesel fuel filter separator is produced in two versions. So, there is a version designed to work with engines with a capacity of up to 300 l / h, and a model for motors operating under huge loads with a large capacity.
The main component is the head, which is then completed with various modules. So, there are three types of filter elements. These are 150 microns, 30 microns, as well as a fine filter for 2 or 5 microns. There are also side and top heaters. There is a sump, the possibility of manual or electric pumping. Reviews say that the device does an excellent job of its function. The cost of such a filter-separator is about 2-3 thousand rubles. The device can be used on all diesel engines with power up to 350 horse power both on cars and on trucks.
