Low ambient air temperatures always complicate the launch of the diesel power unit, which is due to certain features of diesel fuel, whose properties are changed when cooled. That is why all diesel engines are experiencing difficulties during the launch in the cold, although the most modern cars provide for a number of systems that give the car owner. Ability to not notice these difficulties.

How to start a diesel in the winter in the frost, general advice

However, in the regions where winter temperatures are particularly low, these systems may not cope with the required task, if some of their elements are partially or fully failed. In addition, in the system of diesel engine there are several constructive "weaknesses", which are particularly affected by frost. One of the most common problems is the sedimentation of paraffin on the tubes of the fuel supply system. Paraffin is present in any diesel, however, depending on the brand of gas station (or its absence) and the quality of fuel, paraffin in fuel can be so much that it can completely score the tube.

One of the most popular reasons why the diesel engine stalls is non-compliance with the tax owner of the rules of operation. It also affects the violation of the timing of preventive work. For example, every 7.5 thousand kilometers of mileage should be changed oil, since there is a lot of sulfur in diesel fuel. The oil is quickly oxidized enough, which entails the loss of its operational characteristics, and this adversely affects the state of the pistons. It is imperative to regularly monitor the cleanliness of the fuel system and drain waste from the filter and the tank. It is advisable to clean them twice a year, which will give the opportunity to prevent the filter zoom.

Fuel itself also has a huge impact on the operation of the diesel engine. It must meet the operation season. For example, in the winter period, the diesel power unit may sneak as a result of the fact that the car owner applies summer fuel grades, which are thick in frost and turn into a viscous mass. As a result, the fuel pump cannot be fuel to the engine, and since it lubricates the pump, the unit is quickly flashes in its absence. The only way out in such a situation is to drive a car into a warm dry garage to warm up fuel.

How to check the glow candles on the diesel

Glow candles are designed to perform one single function - launch of a diesel power unit. One of the weak links is their small resource. The original candles installed by the manufacturer, as a rule, "live" longer than the rest. There are cases when the motor is started with two work candles of four, but only subject to the condition of the remaining elements.

You can check the candle using a conventional tester without dismantling it from the motor, for which we do the following:

1. Tester Install the resistance measurement mode.
2. The first conclusion of the tester is connected to the mass of the vehicle, and the other to the conclusion of the candle.
3. If the contact is missing, then the candle is defective and it must be replaced.

Diagnosis of candle removed:

1. Let's supply the voltage from the "plus" terminal of the battery on the Candle terminal, the candle housing is connected to the "mass".
2. If the candle is working, its highway will immediately heat up. Ten seconds, she will fool around and starts glowing. If not, the candle makes sense to replace.

How to check the diesel glow candles

It is also desirable to check the relay of the glow of candles, that is, whether the current shield is fed when the ignition is turned on. You can check the light bulb or tester by connecting one contact of the tester to the ground, and the other on the bus. It is better to check on a cold engine, since the relay may not include candles when the power unit has a working temperature.

If the starter turns and the engine does not start, check

If the starter twists, and the motor will not start, but the candles are working for one hundred percent, it is necessary to check the following nodes.

diesel fuel pumping pump

If the frog after a twist starter is drawn up and saved its position either when manually pumping is very slowly returning to the previous position, it means the tank tank mesh has been scored by paraffin or paraffin appeared in the fuel line. In this case, it is impractical in this case, since the chance to discharge the battery is quite large, and the chance to start the motor at the same time.

fuel Mainer Diesel, how to blow

The most effective method in this case is purging by the pump / compressor of the fuel line. Remove the feed from the filter, open the filling lid, blow, the assistant must hear the bouffaging in the tank. If it is not difficult to get to the return, and the compressor is at hand, it is possible to pump the fuel to the compressor will be easier than the manual pump. We close the bayful neck, dismantle the hose from the release of the fuel filter and connect the compressor to the reverse while the filter does not flow from the filter.

how to warm the fuel tank

To warm up the fuel tank, you should substitute a soldering lamp for 10-15 minutes, directing the fire is not on the tank, but along it. We systematically pump up with hand pumping until the solarium flows from the filter out or you will not feel that the solarium is really pumped. If the tank is not warm up, it is possible that when you start the movement, the tank receiving grid will score paraffin again.

if the diesel started, drove a little and does not pull - I scored a paraffin receiving tank mesh, how to heal the tank

If the diesel engine started, drove a small distance and does not pull, then it is most likely (90%), the receiving mesh in the tank was punished with paraffin. To eliminate the problem, you should blow the fuel line and warm up the fuel tank above the described method. Although in this case it is most often enough to warm up the tank below.

craveled the filter of fine cleaning, signs, what measures need to be taken

If the highway is produced by a compressor, the tank is warm, the motor will start, but does not develop turnover, it means that a fine filter has been clogged. On maintaining idle turns of the filtrate is enough, but can not drive. In this case, you should warm the filter (burner or boiling water). The replacement of the filter will give only a short-term result, after which it will score again. A good solution in this case will be pouring a warm (preferably hot) solarium, warming up it or a house in a bath, or a soldering lamp, opening the neck.

Electric preheating, which problems will solve the installation of heating

The main differences between the electrical heaters for diesel motors from similar devices for gasoline engines are due to the parameters of fuel and its behavior in the conditions of negative temperatures of the surrounding among. At low temperatures, the viscosity of the diesel fuel increases significantly. The reason for this is a high paraffin content, as well as different impurities that are present in the fuel.

Different third-party additives that are part of the diesel engineering, during the operation of the motor, we are settled on the walls of the combustion chamber, simultaneously scoring pipelines and filters. Therefore, the engine heaters are installed on cars at the stage of their factory assembly.

The electrical heaters are connected to the power supply network and heat the antifreeze by the electric heating element. The coolant circulates by the system as a result of the temperature difference. To prevent overheating, the built-in thermostat is triggered when the required temperature is reached.

Do not underestimate the data of the device - they significantly facilitate the launch of a vehicle, which is difficult as a result of negative temperatures characteristic of the climatic conditions of our country. Although in the case of diesel cars, the trigger difficulties may appear even with minimal negative temperatures - the viscosity of the fuel at them sharply increases, which is capable of serving that the motor will not be started at all. Heated engine in this case - do not whim a car owner, but necessity. When choosing a preheater heater, it is worth paying attention to its technical characteristics and quality, and not the price of the device.

Defrosts and additives how they will help the car

To prevent freezing diesel fuel, special depressor additives should be used - antigels, which reduce the gelation temperature and the limiting temperature of the filtration, which significantly facilitates the launch of the diesel engine at negative temperatures. But, if the fuel has already frozen and antigels are not effective, it is necessary to take advantage of special defrosts of diesel fuel intended for dissolving paraffin and ice crystals in the frozen diesel combustion.

Tips Prof.

The main thing! Do not allow diesel fuel to turn into a "porridge", use diesel fuel on season.

To defrost diesel fuel, many car owners add various means to it that are not intended for this, such as kerosene, gasoline, alcohol and others. Of course, this is quite effective means in an emergency, however, it is better to still apply special defrosts and additives, to avoid faults in the future.
