Heated fuel filter. How the fuel filter is heated

The fact that the launch of a diesel engine in the winter is very difficult, almost every owner of a diesel-powered vehicle knows. This article describes 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 change in the structure of diesel fuel. When the temperature of the outside air decreases during the seasons of colds in oil, the process of crystallization of paraffin takes place, which contributes to the thickening of the fuel. As a result of these physicochemical processes, the fluidity of the solar cells decreases, and paraffin particles clog the fuel filter. Its throughput is significantly reduced. As a result, the engine starts up badly or does not start at all.

Reduce the factor of thickening of fuel can be popular method, adding a little bit of kerosene or gasoline to it, and also by using various additives to facilitate 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 the cause of breakdown of fuel equipment, filter and engine failure. Owners of diesel units know perfectly well that repair of 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 the start of the engine is to heat 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 the normal operating mode.

Heated fuel filter by own hands

Earlier, our compatriots fought the problem of freezing 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 ignition of the engine and many other negative consequences. At the moment, handicraft ways of heating have come 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

They are a very effective method of eliminating the crystallization time in almost all 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 elements of coarse 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 coolant.

In the work electric heater is switched on from the cabin by auto driver, and is powered by a 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 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 purchase various 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, 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 can be called a filter for fine cleaning. To warm the diesel fuel in this mechanism, a bandage heater is installed, made in the form of a holder. The heater is placed on the outer surface of the element. Heating of 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. Also, they can be used to warm up the filters and mechanisms 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

Nozzles-heaters are installed on standard fuel-collecting areas and contribute to ensuring the supply of solar oil from the fuel tank at very low temperature values. 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 motor power supply system. Typically, such heaters are installed immediately before the fine filtration of fuel. To do this, make a cut in the fuel line and mount the device in it. At the same time, the heating of the fuel filter is carried out due to the receipt in it of already heated diesel fuel. Provide heating in this way you can throughout the period of use of the car.

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

To ensure normal operation and start the diesel engine in winter, it is important to determine how the heating process will be done. To 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 consider the risk of warming up manually, as well as the inability to perform this operation outside the home. It will be much cheaper to purchase a heating device, which in future will save time on warm-ups and will save you from various difficulties during engine start-up.
