One of the most comfortable and productive options for life is the diesel engine. Diesel has many benefits. However, at the same time, it reacts extremely negatively to low temperatures.
Let's say not even low, but very low. The fact is that starting from -20 degrees Celsius, jelly-like flakes begin to form in it. This fact makes engine operation almost impossible. Since the flakes clog the fuel filters, the hot supply stops, as does the engine itself. What to do in such a situation, how to start a diesel engine in frost?
You can cope with different methods. Note that each of the methods in its own way negatively affects the operation of the engine with frequent use.
The use of ether. If you start the engine not on the usual diesel fuel, but on air, then it will work. When the engine heats up by itself, it will be possible to fill in the diesel and continue working. The problem is that ether has a bad effect on the engine body, creating an aggressive environment. Therefore, its frequent use is highly undesirable.
Using antifreeze fluids. This method has many limitations and high cost potential. That is, liquids themselves are expensive, and when the temperature drops by several points, they are no longer effective.
Boiling water can also help to start a diesel engine in frost. The fuel tank is simply poured over with hot water, heating the fuel, and the engine starts to work normally. The problem is that the temperature difference also has a detrimental effect on the engine material.
The most adequate solution to the problem was undoubtedly autonomous prestarting fuel heaters. These small, battery-powered devices heat the fuel that enters the chamber, thereby eliminating fuel freezing problems. The device is certainly not cheap, however, it is the most adequate and correct today.
What do they advise on the forums?1) In winter, it is necessary to fill in winter diesel fuel, otherwise everything else can be skipped (the difference between winter and summer in the temperature of "gelation", that is, the transformation of diesel fuel into a jelly-like substance and the release of paraffin from it.)
2) It is advisable to add an additive to the diesel fuel and preferably Hi-Gear Super Anti-Gel (a 0.5 jar costs about 300-350 rubles, 2 cans are enough for the whole winter). There are two options for adding:
a) Before refueling, pour an additive half-cap into the tank, and the flow of diesel fuel during refueling will stir it sufficiently well.
b) Stir the additive in a can of diesel fuel in advance and pour the mixture into the tank.
And it's important not to forget !!! - the additive must be kept in a warm place - otherwise it can be loaded with a shovel in the cold.
3) We figured out the diesel fuel - let's say the mixture is normal and doesn't freeze too much. why especially? because in Russia there is almost no normal diesel fuel and it still freezes a little and is not willingly sprayed on cold diesel fuel. Therefore, there are complexes for warming up fuel system like Webasto - which heat the diesel fuel from the tank, heat fuel filter and in general, diesel fuel with a temperature of 60 degrees is already supplied to the high-pressure fuel pump .. but Webasto is expensive, so an alternative option is an alarm with auto-heating (auto-start) by temperature. For example, I have a Starline Twage A8 - which starts the car every 2 hours for 10 minutes at night. and in the morning I do not worry about starting at all - because the car does not have time to cool down. The diesel fuel consumption for this action is penny - believe me, it is better to pay 10-20 rubles for a night of warming up than then to walk around the frozen diesel engine.
WELL AND NOW THE MAIN PART OF LAUNCHING !!!
Let's say your car has completely cooled down (it was overnight or even for several days), and it's minus 30 degrees outside. Now we follow the sequence very clearly:
1) Open the hood in advance and remove the air filter.
2) We open the PRE-PURCHASED jar of ether (it is better, too, Hi-Gear Quick start of the engine - something is called that)
3) We turn the ignition key to the penultimate position - they begin to warm up the glow plug chambers (this will just replace the inclusion of headlights to warm up the battery)
4) We warm up the cameras 3-4 times !!!
5) Suction (which on old diesel engines simply adjusts the position of the gas pedal, we remove it completely)
6) We jump out of the car, spray the air into the air intake 3-4 times and run back to the cockpit (here it is important not to miss the moment while the air is in a kind of atomized state)
7) Squeezing the clutch pedal all the way, turn the starter - and on a diesel engine it is better to twist a little than not to twist it !! we twist, on average, 5 seconds each, while carefully playing with the gas pedal - too much gas is not worth it, because cold diesel fuel is poorly sprayed and pours into the combustion chamber with a stream.
Cool Well, in theory, they started up (after all, the air in the cameras ignites with a bang! - only the main thing is not to overdo it and not kill the engine). And do not release the clutch pedal for another 30 seconds - you can stall. Well, with the turnover it is clear - we set about 1500 - and we sit and wait.
9) If not and the starter turns sucks, then you need to charge / top up / buy new batterysince for a diesel engine it is very important that the battery turns the starter quickly. the faster it turns, the more chances it will start from half a turn. (on this, consider the principle of operation of a diesel engine) if the starter turns slowly, then do not even disfigure and do not kill the starter and battery.
10) Well, to top it off, I want to say the main thing: diesel is not gasoline and it needs care! Having missed one thing, a bunch of everything else will come up - for a diesel engine - the mechanics are quite simple, but everything is clearly interconnected.
But if you keep all the units in good condition and handle them carefully, then you will not have any problems and will start up even at 35 degrees below zero.
And by the way, about diesel fuel - in Russia on diesel engines it is recommended at least once a year to drain the leftovers from the fuel tank and rinse it - because so much "shit" settles there from our diesel fuel that it then very quickly clogs up all the nets and filters.
IN winter time starting the engine "cold" sometimes becomes an impossible task for motorists. Sometimes this requires a lot of effort. But not every car owner has so much free time. But how can you avoid this situation? In today's article, we will tell you how to properly start a diesel engine in winter. We will also consider tips, thanks to which you will not find yourself in such unpleasant situations so often.
Looking for a "common denominator"
How to start a diesel engine in cold weather? First, let's look at the reasons for the bad at low temperatures. Let's say right away that there are a lot of them. But most of them have a common denominator - liquids. Moreover, the lower the temperature environment, so worse engines they will work.
In the case of a diesel engine, frost affects the fuel. With a rapid drop in temperature, it begins to thicken, which is why the composition of the liquid changes. As a result, the fuel is difficult to ignite or does not pass at all through the fine filter.
A battery is also associated with liquids, in which they constantly run chemical processes (generating electric current). And the lower the air temperature, the slower they occur.
Another reason bad start diesel car can become motor oil... It, like fuel, also tends to thicken. Thus, with a decrease in temperature, the movement of rubbing parts of the KShM becomes more complicated. It is even worse if the oil film breaks or disappears altogether. Then overhaul power plant inevitable.
How to start a diesel in winter? First start
If your vehicle does not start the first time, no need to panic. This process should last no more than 15 seconds. After that, turn the key to its original position and let the battery "rest" for one or two minutes. Ideally, the car should start with a maximum of 3 attempts. If your car still won't start, under no circumstances repeat this process many times. So you will only worsen the performance of the starter and discharge battery.
Start by "lighting" method
In winter, always keep ready-made cables "in reserve". Thanks to them, you can start the car quickly. You can be assisted not only by an acquaintance, but also by any friendly driver passing by you.
If the car can be started by the "lighting" method, it can safely go on. But it is worth noting that you should not turn off the engine immediately after ignition. Let the battery fully "saturate" with electricity after driving at least 5 kilometers. Better yet, let the engine run for about an hour. In this case, it will definitely renew its charge and at the next start it will give a normal
Use of additives and antigels
So, we have her frozen, if not close suitable carfrom which one could "light"? Then welcome to the world of additives and antigels. Fortunately, finding them is not difficult, even in small towns. Often, car enthusiasts prefer such renowned manufacturerslike "Liquid Moli", "Khado" and "Castrol". Due to their composition, they do not allow the paraffin, which is contained in diesel fuel, to multiply in in full... The fact is that when the temperature drops, this fuel begins to grow cloudy, forming a special sediment. Because of it, the diesel fuel does not enter the combustion chamber, getting stuck in the walls of the filter.
Note also that additives and antigels do not dissolve paraffin in liquids, they only retard its growth at the next decrease in temperature. But, as practice shows, this is quite enough to start a diesel engine in 40-degree frost. True, for this you need to know how to use antigel correctly. And it is poured into the tank at temperatures above 0 ... + 1 degrees Celsius. In this case, the tool brings real benefits to the engine.
Nuances of antigels
Modern automakers do not recommend the use of additives in fuels. This applies to TDI, HDI and CDI engines. This prohibition is explained by the complexity of the design of the fuel equipment. But car enthusiasts say that when used carefully and moderately, the additive does not cause any harm to diesel installations.
When using antigels, it is important to pay attention not only to the ambient temperature, but also to what proportion you need to add liquid to the tank. Manufacturers indicate this information on labels.
What to do if the diesel fuel is already frozen?
How to start a car in winter if the fuel is already frozen? Of course, already frozen diesel oil, full of paraffins, cannot be “revived”. The only way is to pour it into a canister and heat it to a temperature of 60-70 degrees Celsius. Then add a few milliliters of antigel and pour the resulting substance into the tank. But before starting the car in winter, motorists are advised to first install a new fuel filter.
Details about kerosene
Experienced drivers do not trust various new products in the form of antigels and additives and usually prefer to dilute diesel fuel with kerosene. In practice, the result is the same, and this method can be used not only on old engines. Kerosene has a high lubricity, so it does no harm. Experts recommend diluting diesel fuel with this fuel in a proportion of no more than 30 percent, that is, for 100 liters of diesel fuel, a maximum of 30 liters of kerosene.
Petrol
But this type of oil products should be completely deleted from the list of used "heaters" for diesel engines. The fact is that gasoline, unlike additives and kerosene, has no lubricity. This means that while the motor is running, the injection pump will pump liquid "dry". Therefore, before starting a diesel engine in cold weather in this way, remember that repairing fuel equipment can cost from 200 to 500 euros. As a last resort, it is recommended to dilute gasoline with oil.
Glow plugs
Before starting a diesel engine in winter, you need to thoroughly warm up the candles. How to do it? First you need to turn the ignition key, then wait until a light bulb in the form of a spring appears on the instrument panel. Most often it is yellow or red (you can see it in the photo below).
After a couple of seconds, it disappears, informing that the fuel has warmed up sufficiently. After that, return the ignition key to its original position. To completely warm up the glow plugs, you must repeat this procedure several more times with an interval of 2-3 seconds. The fact is that foreign manufacturers do not quite know what kind of low temperatures their cars have to face in Russia, especially in the northern regions. Fuel mixture during this period, it is simply not able to warm up normally, so this procedure should be repeated with the key turns more than once.
Also, before starting the diesel engine in cold weather, it is recommended not to remove the car from the gear, but to squeeze the clutch all the way (applies to cars with manual transmission). The fact is that in winter transmission oil tends to stagnate, that is, removing the machine from the gear, you force the discs and gears to slide without lubrication.
The car was frozen. How to start it from the pusher?
Unfortunately, this method cannot be used on vehicles with such engines.
The reason for this is the timing belt, which can break or jump a few teeth forward. Therefore, any attempt to start a diesel engine "from the pusher" in most cases turns into costly repairs.
Of course, it is best to prevent these occurrences. For this we recommend:
So, we figured out how to properly start a diesel in winter. We hope you find the tips above helpful. Good luck on the road!
Winter in Russia for many car enthusiasts usually comes suddenly, and most car owners find out about it only at the moment unsuccessful attempt start the engine of your "iron horse". In this article, we will try to give useful and sensible advice for car owners, not only, but also for owners of cars, as well as owners of equipped cars.
But the most important argument for a successful start of the car engine in frost is the serviceability of the battery (the electrolyte density should be 1.26-1.28 g / cm3). Below is the data on the freezing of the electrolyte, depending on the current characteristics of its density:
1.25 g / cm3 -50 ° C, 1.20 g / cm3 -25 ° C, 1.15 g / cm3 -14 ° C, 1.10 g / cm3 -7 ° C, 1.05 g / cm3 -3 ° C.
You can check the density of the electrolyte of the battery at a service station or on your own by purchasing a device necessary for this procedure - a hydrometer. Of course, you also need to ensure the serviceability of the starter and generator, the presence of new (working) high-voltage wires and spark plugs, reliable fastening of the battery terminals, pure synthetic or semi-synthetic oil in the engine, preferably only synthetics in the gearbox. Replaced air, oil and fuel filters, and at least ½ full fuel tank capacity are also important for a successful engine start. But the most important point is the battery.
Running gasoline engine in frost.
Let's simulate a situation - morning, temperature minus 25ºС, a car with "mechanics". We open the car and ... don't try to start the engine right away. First you need to warm up the battery, one of the surest ways is to turn it on normally high beam (just blink your headlights for 10-15 seconds), then turn the key in the ignition lock and wait for the fuel pump to pump fuel into the system. We squeeze the clutch pedal all the way (gearbox to neutral) and try to start the engine (for cars with injection engines, in no case touch the accelerator pedal, for carburetor engines we pull out the choke knob). If the car is in good working order, the starter will "revive" the engine within 5-7 seconds, but sometimes a second attempt is required. Take your time, wait a minute, and then try again the algorithm described above - the engine will start, with a successful start, gently and slowly release the clutch pedal. If the engine starts to lose speed when the clutch pedal is released, depress it again and hold for 20-30 seconds, try again (the oil in the gearbox will warm up), the pedal can be released.
Warm up injection engines it is recommended no more than 2-3 minutes, and for carburetor minutes it will take about 10 minutes. At this time, it is necessary to prepare the car for safe movement, clear frost or ice from frozen glass overnight, and the interior needs to be warmed up at least a little. Well, now on the road, we leave and move at a speed of up to 50 km / h, try not to greatly increase the engine speed until the operating temperature rises to 50-60 degrees.
Running diesel engine in winter.
As in the case of a gasoline engine, a "live" battery is required to start a diesel engine, but due to the design features of an engine running on heavy fuel (diesel fuel), important factors affecting a confident start in winter period... the glow plugs are in good working order, the condition of the air and fuel filters, winter fuel... "Summer" diesel fuel begins to grow cloudy (paraffins crystallize and clog filters and the entire fuel system) at temperatures below 0ºC. So we strongly recommend switching to winter fuel in winter (up to -25 ° C), but for severe climatic zones with temperatures from -30 ° C and below there is an Arctic diesel fuel... IN real conditions even after refueling with the correct "winter diesel" it will not be superfluous to use depressants (prevent fuel thickening), in extreme cases add kerosene (80-85% summer diesel fuel and 15-20% kerosene) to diesel fuel.
The most advanced owners install fuel and fuel line heating systems on their cars with diesel engines (). The algorithm for starting a diesel engine is exactly the same as that of its gasoline counterpart. If there are no problems with diesel fuel and the battery, then the launch goes without problems. In case of thickening of diesel fuel, in no case should you heat the pipes of the fuel system with an open fire, because you do not drive a Kamaz.
Starting the car engine with automatic transmission in frost.
Automatic transmission (if it is not ready for operation when low temperatures) complicates engine starting in winter conditions. The oil in the box that has thickened overnight counteracts the rotation of the automatic transmission shafts. If in the case of “mechanics” the driver disengages the box by squeezing the clutch, then the “automatic” cannot be turned off and the starter has to put more effort to unwind the engine and the box. So the most important aspect for a car with automatic transmission is a timely oil change in the gearbox (the cleaner the oil, the easier it is to start the engine).
In conclusion, I would like to say that if your car “doesn’t want to start up in cold weather,” there are options: “light” from another car and pull the car “on a tie”. The first option is preferable, but cases of "dying" of the engine control unit and ignition coils for cars with injection engines are not uncommon. Nothing will happen to carburetor engines, you can safely start "from the pusher". But in any case, do not try to start a car with automatic transmission using a tug (the box will fail).
Our advice - a new battery, good wiring, winter fuel and a garage (not even heated) will allow motorists to spend the winter in peace.
Many owners diesel cars they are anxiously awaiting winter frosts, since almost each of them had to face the fact that the car would not start in subzero temperatures. The main reason for this is the thickening of diesel fuel at negative temperatures. This nuisance comes in because of the formation of small paraffin particles in diesel fuel. However, if you apply the little tricks that experienced drivers use, you can figure out how to start a diesel engine in cold weather.
In order for a diesel engine to easily start in severe frost, it is necessary to take into account such important factors:
- good and proven fuel;
- reliable battery;
- working starter;
- quality candles.
A prerequisite is also normal compression and serviceable injection system... When at least one of these points is inoperative or does not work well, the diesel engine will not start in frost. Before the onset of cold weather, it is necessary to check the operation of the engine in a good workshop. A fuming engine indicates a lack of power, uneven operation, or problems with compression. This is one of the main indicators that can characterize the entire operation of the motor.
The diesel engine is checked using a pressure gauge that is connected directly to the injector. Thus, it is checked operating pressure in the cylinder during operation crankshaft... If the car is new, then this figure should be at least 30-40 bar. If the pressure in the working cylinder is lower than 20 bar, then the start of the diesel engine in frost will definitely not take place. But this is more common on cars with high mileagewhere the engine is already exhausted. In this case, a major overhaul of the motor is necessary or, as an option for the winter, a warm, heated garage. In the warm season, even a heavily worn engine starts without problems.
Possible problems with the injector
In older cars with high mileage, the injector problem usually appears when the car is started, power is also significantly reduced and fumes exhaust pipe... Such an engine starts to work too noisily, as if it knocks with something metallic. If the car is new, you can find out that the injector is inoperative by hard braking after pressing the gas pedal. The cost of repairing an injector varies depending on the year of manufacture of the car, the newer the car, the more expensive it will be to repair the injector.
Battery Disadvantages
As practice shows, starting any diesel car is much more problematic than starting a car with a gasoline engine of the same power. Therefore, batteries and starters are much more powerful on diesel engines. In winter, all defects of the batteries manifest themselves in a double size, since in severe frosts the need for the engine for electricity increases significantly. The fuel thickens from frost, the starters rotate more intensely, and the candles need to work longer. Usually, the more cold it is outside, the less battery power is. How to start a diesel engine in cold weather is becoming a major issue even for experienced car owners.
To avoid many problems in advance, you need to take a closer look at the work of the starter. If it does not work well or after a couple of attempts to start it up noticeably weakens, then you need to contact a specialist. The service station will check the performance of the battery and all parts of the car used to charge it. If you immediately buy a new battery without checking the old one, then it is often just a waste of money, perhaps the problem is not in it. The generator or starter may be defective. The service life of modern batteries is three to five years.
Fuel and fuel filter problems
With a sharp drop in temperature in most tanks diesel cars summer diesel fuel, which tends to thicken strongly at a temperature of zero degrees, is also filled in. Paraffin deposited in frost from such fuel can completely clog the fuel filter, this is one of the reasons for the impossibility of starting a diesel engine correctly in frost. If for any reason summer fuel was not used in time, it is necessary to pour into the tank special additive - antidepressant. This will help reduce the thickening parameters of the diesel fuel. Experts recommend changing the fuel filter before the onset of frost; in diesel engines, the filter design provides for a sump for collecting water, if a lot of liquid has collected in the sump, then it will freeze in frost and limit the flow of diesel fuel into the engine.
Most diesel owners think that diesel engine trouble in winter is due to diesel fuel that is out of season. There are only three types of diesel fuel:
- summer diesel fuel - used from zero degrees and more;
- winter diesel fuel - poured at negative temperatures up to minus thirty degrees;
- arctic fuel - used in diesel vehicles at temperatures below minus thirty degrees.
The main difference between all these grades is the fuel thickening temperature. If the fuel is filled for the season, then the use of special additives is not required. If all systems of the car are working properly, the diesel will start in frost on the first try.
Malfunctioning candles
It is very rare that all car plugs fail at the same time. If the car is old and with high mileage, the driver may not even notice a malfunction of a separate candle, just when the engine starts up, the engine starts weaker and its operation is uneven for several seconds. In the fall, it is advisable to revise car candles and replace faulty elements.
The performance of candles can be checked without contacting specialists. The element must be pulled out, the contact from the minus must be connected to the body, and the plus must be thrown onto the plug terminals. When the candle is working, its tube will instantly warm up. After a few seconds, it will fully heat up and it will glow.
Proven diesel starting methods
A very reliable and proven way to ensure the correct functioning of the fuel structure of a diesel vehicle is to install a heating structure in fuel tank, on pipes and on the filter. It is very easy, although dangerous, to plant a diesel engine using a tug.
Passenger cars are equipped with a belt-type distribution system drive. When a tug is used, jerks are inevitable, this can lead to a break in the belt. The tug can only be used in desperate situations when the battery is dead or the starter is broken.
Take some advice from experienced drivers:
- if the diesel engine starts in frost, it must be turned on for a few minutes high beam, then squeeze the clutch for a few seconds, and then give the starter a rest, this can help the diesel plant;
- you can add kerosene to the fuel, even with prolonged operation at subzero temperatures, such a composition does not affect the operation of the entire structure of a diesel engine;
- use additives that reduce the thickening temperature of diesel fuel;
- to quickly warm up a frozen diesel engine, you can put on a cover on the car and put a heat gun under the bottom. The temperature under the engine must be brought to at least zero degrees;
- if we start a diesel engine in frost, then for a quick plant, you can sprinkle ether into the air intake, you need to try to start the engine while the ether is in a sprayed state;
- another time-tested method from experienced diesel drivers. If the car does not want to start in cold weather, it is necessary to warm up the drain manifold. This can be done simply with a piece of paper and matches. The paper is set on fire and the collector is heated with the help of smoke, the car in this case starts up very quickly;
- you need to buy diesel fuel only at proven gas stations, saving on diesel fuel, you can spend a lot on repairs.
Conclusion
Diesel vehicles are popular due to their power and economy in operation. But for all these advantages, lovers of such cars suffer in winter frosts... Especially troublesome is the transition period from autumn to winter, it is at this time that there are frequent frosts, and the fuel in the car is mostly filled with summer fuel. So you have to spend hours trying to start your car. If you follow the advice of experts and closely follow the machine, then even in severe frosts, such problems will not arise.
Many car owners living in regions with cold winters are faced with the problem of starting a car in frost. This is especially true for diesel cars, which are difficult to start at subzero temperatures, due to the peculiarities of their design. There are several reasons why the diesel engine cannot be started. A good car owner needs to know what is causing the problem and how best to fix it. In this case, the likelihood of starting the engine, even in frosty weather, is higher. But more about everything.
What features of a diesel engine you need to know
To understand how to avoid problems when starting a diesel engine in cold weather, it is important to know the features of its operation and design nuances. As a rule, the causes of malfunctions lie inside the motor. Let's highlight the most important of them:
The main reason why it is often not possible to start the engine at subzero temperatures is diesel fuel. The composition of this fuel contains paraffins, which precipitate at zero degrees. With further cooling, the fuel takes on a gel-like form and loses its ability to pass through the filter, and then to the engine. Logically, a diesel engine won't start without fuel.
FUEL IGNITION METHOD
Another reason why problems with starting in frost are possible is a special option for igniting the fuel-air mixture in the combustion chamber. So, in gasoline engines the fuel is ignited due to the appearance of a spark from car candle in the cylinder. Diesel engines work on a different principle. In them, the fuel is ignited by high pressure.
The algorithm is as follows. Fuel is injected into the combustion chamber, heated under pressure to 800-900 degrees Celsius, and then ignited. If it's freezing outside, starting a diesel engine becomes a problem, due to the impossibility of heating the fuel to the desired temperature. It is for this reason that the diesel engine cannot be started.
During operation, the car owner must know the reasons discussed above, and be able to act if difficulties arise during the start-up process.
Engine cranking features
What to do when it's frosty outside and you need to urgently start diesel engine? Regardless of the foresight and correctness of preparing the car for cold weather, it is important to know the nuances of the "winter" start. When following simple tips, it is possible to avoid many problems, including those associated with the engine.
The first thing to start with in cold weather is to warm up the battery and candles. A common mistake many newbies make is turning on headlights. This recommendation is relevant only for gasoline cars. If a diesel engine is installed in the car, it is enough to turn the key in the ignition lock and hold it for 12-15 seconds. This is enough to warm up the battery and glow plugs, and then start the diesel.
Some cars are equipped with a Start-Stop button. Their peculiarity lies in the presence special system, providing preliminary heating of the candles. To perform the necessary work, just press the button and hold it in this position for six seconds. At some point, on dashboard the icon should light up, signaling the possibility of starting the motor.
The diesel engine must be started with the clutch engaged. The starter motor rotation time should be about 15 seconds, which is enough to start the engine. If it was not possible to start the diesel engine the first time, it is recommended to turn off the ignition, wait a few minutes and try again.
In a situation where the above actions did not lead to success, you can use emergency methods of starting in frost. The options are as follows:
1. Check the condition of the fuel. If the diesel fuel is frozen (thickened), it is worth calling a towboat and putting the car in a warm place to warm up the fuel system.
2. If there are no problems with fuel, you can go the other way - warm up the engine. To solve the problem, you need a blowtorch and a piece of tin. Then proceed as follows. Place a tin under the car and heat the engine by directing the lamp fire onto the metal of the diesel engine. Make sure that the flame does not spread to nearby areas of the car. It is optimal that heating is carried out by a warm air stream, and not by the fire itself. Alternatively, you can use the "quick start" device.
3. If it was not possible to start the diesel with the help of the considered tips, there remains one more attempt - to start the engine with the help of a tug. The advantages of the method are the high probability of success. On the other hand, timing belt vehicles are at risk and could fail. If there are no other options, you can start a car in frost in this way.
How to eliminate problems in the future
It is no secret that the best treatment is not the drugs themselves, but the prevention of the disease. By the same principle, you can act in the case of a car. In order for the diesel engine to start without problems even in cold weather, it is worth taking certain measures. Some simple steps allow you to avoid problems in the future and additional spending on the repair of the fuel system.
The first thing to do is to choose the right fuel. Note that starting the engine in winter, with summer diesel fuel in the tank, is unlikely to work. The reason is the wrong choice of diesel fuel, which is of three types:
SUMMER. Feature - fear of low temperatures and freezing, already at five degrees of frost. Summer fuel density - up to 860 kg / cu. meter.
WINTER. Such a diesel engine can start even in severe frost (at temperatures up to -35 degrees Celsius). Maximum density - 840 kg / cu. m.
ARCTIC. If such fuel is filled, it will be possible to start the engine up to a temperature of 55 degrees below zero. Density parameter - up to 830 kg / cubic meter.
Since November, winter diesel fuel has been sold at filling stations. But here it is important to consider a number of points. In particular, mix different types diesel fuel is not recommended. Gas station employees know about this, but often do not wait for the sale of all summer fuel, and fill the tanks with winter diesel. As a result, instead of high-quality diesel fuel, drivers are refueled with a mixture of summer and winter fuel, and frost resistance decreases. That is why, at first, you should not trust 100% fuel from a gas station. It is better to play it safe and add anti-gel additives to the tank.
To eliminate problems with starting the engine in the future, you can install a preheating, which is the main assistant of a diesel engine in cold weather. The most common option is the use of liquid fuel heaters. One of the best representatives is the Webasto model. Electric heaters are the second most popular.
It doesn't matter what type of device you use. The main task of the devices is one - to help start the diesel by heating the fuel.
Before winter starts, check the battery for good condition. If the power supply is not performing its function, it is better to replace it. Preference should be given to batteries with a higher starting current.
Frost carries many risks for the car owner and his car. To avoid difficulties with starting a diesel engine, it is important to start it correctly and fill only with high-quality fuel. With this approach, it is possible to solve another problem - to extend the service life of the motor, and, in the future, to save on its repair.
