Start the engine in frost. Starting the engine in frost

Many motorists leave the car in their garage for the whole winter, as driving in this period is not only dangerous, but also requires a certain skill from the driver. The majority in a snowstorm or ice falls on public transport or a taxi. But those who still decided to go to work on their own car, may face the problem of starting the engine in the cold.

Starting the engine in frost

Most often, injector cars do not start at temperatures below -20 degrees Celsius. The reasons may be mass, but the main one is the obsolete firmware of the electronic control unit. To get rid of this you can only fill the bay with a more recent firmware. But there are many other problems that need to be addressed. One such is the lack of heating in the room where the car is. This leads to the fact that the battery is out of order.

If the battery freezes, then it itself is discharged, and since a larger charge is required to start the engine in the cold season, rather than at normal temperatures, this is what becomes the main problem. There are several ways to solve. First, store the battery only where it is more or less warm. Secondly, do not charge the battery to the limit. It is due to the fact that the density of the electrolyte changes, and while it is in the cold, it loses its properties, and the charge falls.

A few more effective ways

It is worth paying attention to the fact that the engine can be started in the frost even from the pusher, but this applies to the manual gearbox. There is another way to warm up the battery. To do this, you can turn on the external lighting for 1-2 minutes, and then try to start the car.

But if it is not possible to succeed, it will be necessary to open the hood and carry out several manipulations already there. For example, you can blow the cylinders, which sometimes helps, as well as replace the spark plugs. It should be noted that the start of the engine in the frost for the first time must be performed without the gas pedal. If it did not, then after blowing the cylinders, you can try to start with a pedal.

Do not forget about the air damper (suction). If you pull it yourself, it will be much easier to cope with the problem. In any case, before you leave the car to spend the winter in the garage, you need to check the life of the candles, the start system, oil seals. As for motor oil for the winter, this is a separate topic for conversation, as will be discussed below.

Starting the carburetor engine in frost

As for cars carburetor, then there are their problems in the winter. Often this is a malfunction of the vehicle's internal systems. In a very fierce frost, the inability to start a car from the first time and at all a normal phenomenon. Most often this problem is solved by setting the contact ignition and its adjustment. But the role of start systems also plays a role, which must also be pre-configured.

Of course, starting the engine in frost will be much easier if the starter is working. This mechanism can consume much more current than it needs, and at the output do not give enough voltage to start an auto. It is possible and necessary to combat this. It is worth buying a new one or repairing or adjusting an old starter.

Another proven method that will help solve this problem is the installation of a more powerful battery. The staff battery for 55 Ah can be changed to the one that is designed for 60 Ah. As noted above, the battery charge should be above average, but not the maximum, it is optimal for starting the engine in the frost.

How to successfully start in -20, or Select an engine oil

After we decided on the launch of carburetor and injector engines, it is worth a few words to say about motor oil, which plays almost a key role. Currently, the following oils are produced:

• Mineral;
• Synthetic;
• Semisynthetic (mineral and synthetic).

Mineral oils are used for internal combustion engines up to the 90th. Consequently, vehicles of the VAZ family use mineral oil. But there is one "but". The fact is that such oils thicken at low temperatures and do not allow the engine to start in the cold. VAZ well tolerates semi-synthetic, so it is suitable for winter. Do not forget that the model 2101-2107 is often difficult to get because of incorrectly adjusted ignition.

As for synthetic oils, they contain a large number of different additives, and also thicken at a temperature below -40 degrees Celsius, so this is an ideal option for the winter period.

Than use of poor-quality fuel is fraught

The fuel system of the car is quite complicated, but, regardless of the car brand and its service life, high-quality gasoline or diesel must be poured into the gas tank. If starting the engine in winter in frost is a problem for you, then first of all you need to make sure that the fuel is not diluted with water. If this is so, then in the frost condensate and water will freeze, this disrupts the operation of the car's systems and makes start-up difficult.

The only reasonable solution to this problem is that it is necessary to drive the car into a heated place where the water is thrown together with the condensate. But it is highly recommended not to go anywhere on such gasoline. There are also fuel dehumidifiers that allow you to draw out the remains of water so that the car runs on clean gasoline. But this is only a temporary solution to the problem, which will allow you to start your car in the cold.

Solving problems with starting a diesel engine

There are many problems that make it impossible to start a diesel engine. Let's consider the main of them, and also we will find methods for their solution.

A frustrated moment of fuel injection . With late injection, starting a diesel engine in frost is almost impossible. In addition, it is often difficult to determine whether this is the case. This will require a diagnosis.

Another actual cause is leakage of the battery current. If this circumstance can not be so noticeable in the summer, as the starter spends less energy for launching, in the winter this issue requires an immediate solution. Most often, the problem is in the winding (somewhere something is shorted). All this is detected by an elementary visual inspection. It is advisable to check the generator belt for the degree of wear and, if necessary, tighten it. After that, most likely, you can immediately start the engine in the frost without any problems.

Frequent problems and solutions

Let's consider some more problems with which motorists collide in the winter, when it is necessary to leave the garage, and the car does not start. Spark plugs can be flooded. This happens quite often, and there is nothing horrible about it, but it's unlikely to leave somewhere. You just need to clean the candles so that you can see how the spark passes. They can also simply be changed or calcined on the stove.

It happens that the car is in the garage for a month, and the last time it left there, it was still warm, and the so-called "summer" diesel fuel was filled in the tank. In the cold, it becomes like jelly, and the car does not start. To solve the problem, you can resort to using autochemistry, such as "Quick Start" or something like that. You can warm the hoses of the fuel system with warm water.

Conclusion

If you drive a mechanic, then start in winter, you need to perform with a fully squeezed clutch. This allows you to reduce the direct load on the starter. It is also recommended that the exhaust pipe be periodically cleaned of accumulated condensate, which is also a working method.

Of course, it is equally important to leave the car for the winter, having prepared it beforehand. This can be done by cleaning the candles, cylinders, etc. As for the diesel, it is recommended to start it on the first attempt. The starter can be twisted for about 10 seconds. If grasping did not happen, then you need to look for a solution under the hood.
