Operation of a diesel engine in the winter: capricious simplicity
Motorists of Siberia and the Far North have accumulated vast experience in operating diesel engines in the harsh Russian winter. Many residents of these extreme regions do not jam the engines of their cars for the night at all, or put coils in the fuel tanks through which hot water constantly circulates, and sometimes exhaust gases. But this is extreme measures for desperate situations. Basically, recommendations for the operation of a diesel engine in winter are quite real and easily accomplished. The main thing is to do everything based on the advice of professionals and automakers.
Why in our country are so many adherents of “diesel driving”? There are good reasons for this. First, there is no carbon monoxide in the diesel exhaust. Secondly, diesel, unlike gasoline, is not such flammable fuel, which makes the car much safer. Thirdly, the diesel engine in the water feels like a fish, but candles and high-voltage wires of gasoline machines will surely fail in a wet environment. Fourthly, diesel engines have a greater burden at low revs, which is important when it comes to off-road conditions. And, finally, diesel engines have a greater power reserve and lower fuel consumption. Looking at all of the above, one cannot but agree that diesel is good. But for the time being. When winter begins to lay its feather bed, diesel cars become a real headache for their owners. And it’s all in diesel fuel, which can not stand the cold.
When paraffin is not a friend
One of the components of diesel fuel is paraffin, which does not make itself felt, while the thermometers frolic above 0 ° C. But with the arrival of the first cold weather, diesel fuel begins to grow cloudy and fill with paraffin “threads”, which thickens in the cold and clogs fuel filters. That is why there is summer, winter and arctic fuel, each of which has its own cloud point (–5 ° С, –25 ° С and –35 ° С, respectively).
The only way to combat rebellious paraffin is to add special depressant additives to the diesel fuel. In extreme cases, diesel can be diluted with conventional kerosene in a ratio of 15% kerosene and 85% diesel. In hopeless situations, you can “drink” a diesel car and gasoline, adding it to diesel fuel, but in this case you will only bring the death of your “steel horse” closer.
It is important not to forget that any additive can only be poured into the tank of a well-heated car. Otherwise, all attempts at resuscitation of thickened fuel will be in vain.
The use of additives, which are also called “anti-helium”, is not recommended by any of the well-known automakers. Moreover, they are strictly prohibited to use. The main means of struggle, which will not deprive you of warranty service, is Euro-4 high-quality diesel fuel, which corresponds to the season. But you and I know perfectly well how our tankers “spoil” us with high-quality fuel. In other words, there is no high-quality diesel fuel in our country, and even if there is, then filling a car with it is the same thing as filling home-made pasta with White Truffle Marinara sauce.
But if you made a firm decision to “add” the fuel in the tank of your car with the help of depressor “gravy”, then try to choose the “anti-gels” of well-known manufacturers, including BP, Shell, Total, Wynn’s and others.
The transition period can be considered critical in terms of operating a diesel engine. When autumn has not yet resigned its powers, and winter lurks around the corner, they continue to sell summer diesel fuel at gas stations. You can refuel in the evening, and in the morning weep over jelly in the tank of the car in the middle of the frost. If this happens, then it is better to call a tow truck or ask a colleague to take you in tow and go in search of a warm box where diesel can “move”.
Starting candles: good condition – the key to a successful wintering
Often it happens that a cold car in the morning does not want to start. In diesels, the combustion chamber, before the engine starts, heat the starting plugs. Electronics controls the temperature of the air and adjusts the duration of the candles. The starter can be turned on only after the candlestick indicator on the dashboard goes out. In the event that hellish cold reigns outside, then you can start several warm-up cycles manually using the ignition key. This ensures that the motor will start for sure.
But such a focus is possible only on older cars, in which electronics is represented by a minimum set of functions. But in modern models, electronics decide for themselves when to turn on the starter – that is, right after the candles turn off.
