Heated fuel filter. How the fuel filter is heated

The fact that the launch of a diesel engine in the winterthe period is very difficult, almost every owner of the transport with a diesel engine knows. This article shows the main reasons for the poor start-up of the engine and how to get rid of this problem: by installing a diesel fuel filter with heating on the engine or using popular heating methods.

Causes of difficult start-up

The main problem is the restructuring of thediesel fuel. When the temperature of the outside air decreases during the cold season in oil, the process of crystallization of paraffin takes place, which contributes to the thickening of the fuel.

As a result of these physicochemical processesThe fluidity of the solar cells decreases, and paraffin particles clog the fuel filter. Its throughput is significantly reduced. As a result, the engine does not start properly or does not start at all.

Reduce the thickening factor of fuel canfolk method, adding a little bit of kerosene or gasoline to it, as well as by using various additives to ease the start-up. But this method can not always help and has a number of significant contraindications and limitations. The use of inexpensive and substandard additives can be a cause of breakdown of fuel equipment, filter and engine failure. Owners of diesel aggregates know perfectly well that repairing the fuel system can cost a tidy sum. And it does not matter, domestic is a car or a foreign car.

Effective way to facilitate start-up

The most effective way to facilitate startmotor is the heating of the fuel filter, in the body of which there is accumulation of paraffin deposits. Crystallized paraffin clogs the microscopic holes of the filter element, which prevents the normal flow of fuel through it. The supply of the solar oil partially or completely ceases, which leads to various problems. At the same time, as already mentioned, the engine is badly started, there is a significant reduction in power, interruptions of normal operating conditions.

Heated fuel filter by own hands

Earlier our compatriots struggled with the problemfreezing of fuel in a rather primitive form. The fuel system and its elements were heated by using a soldering lamp or a self-made torch, hot water and household electric heaters. These measures were carried out with a high risk of engine ignition and many other negative consequences.

At the moment, handicraft ways of heatingcame to the back burner, as it became possible to install special electric electric heaters that heat the fuel filter and solar oil without any consequences.

Preheaters

Are very effective method of eliminationthe moment of crystallization practically under any severe weather conditions. As a rule, these devices are installed on the nodes of the fuel system, which are more susceptible to "freezing".

These include filtering elementscoarse and fine cleaning. The heater, which is located on the coarse filter, is responsible for heating the fuel, which is necessary to start the diesel unit. At the time of use of the car, the heating of the mechanism is carried out by means of the reverse current of the cooling liquid.

The electric heater is switched on fromcar driver, and is powered by a rechargeable battery. The power of the heater depends on the amount of diesel fuel consumed, and can be 15-150 W, with an on-board car of 12 V, and 25-250 W with a 24 V network. This type of heating helps to heat the filter to the required operating temperature, resulting in crystals of paraffin compounds are melted in a very short period of time, up to about five minutes. When using a combined heater, the heating process continues until the engine coolant reaches a temperature of forty degrees, after which the electrical heating is switched off.

Benefits of using the device

Using a heated filter on the car, it is possible to significantly increase the working life of the engine.

Also there is no need to purchasevarious start-up additives, the battery saves its resource. Starting the engine in the cold period contributes to excessive wear of its parts, and in case of easy start-up and rapid warm-up, the wear factor is significantly reduced. Also, frequent repairs of the fuel system and its connecting elements are excluded.

Types of heaters

They differ in form, method of manufacturing and installation, as well as in production indicators.

Taking into account the functional features of the heaters, they are divided into several types, which in different ways are heated fuel filter diesel:

Rod heaters.
Tape.
Bandage type.
Flow type.
Nozzles-heaters.
Fuel Inlet.

Assignment of a shroud heater

The most vulnerable part of the fuel system isname the filter for fine cleaning. To warm the diesel fuel in such a mechanism, a bandage heater is installed in the form of a cage. The heater is placed on the outer surface of the element. Heating the fuel filter is due to the heater's consumption of electricity from the battery. As a rule, it turns on five minutes before the engine can be started.

Tape

They are used mainly for heating fuel lines both before starting the engine and during its operation.

heating the fuel filter by one's own hands

They can also be used to warm the filters andmechanisms of the system. Due to the special design (made in the form of a ribbon wire), they can wrap any parts. Heating the diesel fuel filter with such a device ensures a normal and reliable operation of the filter element, with high throughput.

Nozzles

The nozzles-heaters are installed on thestandard fuel-collecting areas and contribute to ensuring the supply of solar oil from the fuel tank at very low temperature. Heated fuel in the tank has a more liquid structure, it does not have paraffin crystals, so it is easier to take in the intake. This heater is powered directly from the vehicle's on-board network.

Flow type

It can act as an additional equipment for the power supply system of the motor.

As a rule, such heaters are installedjust before the fine filtration of the fuel. To do this, make a cut in the fuel line and mount the device in it. Thus heating of the fuel filter is carried out due to receipt in it already warmed-up diesel fuel. Provide heating in this way you can throughout the period of use of the car.

The operation of heating the fuel filter is described in detail in the instructions for the use of a heating device.

To ensure normal operation and start-upDiesel in winter it is important to determine how the heating process will be done. To pre-heat the fuel filter with your own hands or with the help of special equipment - this is strictly a personal matter for every vehicle owner.

But it is important to take into account the danger of warming upmanually, and also impossibility of performance of the given operation out of house conditions. It will be much cheaper to purchase a heating device, which will save time on warm-ups and save you from various difficulties during engine start-up.
