Many motorists leave the car in theira garage for the whole winter, as riding in this period is not only dangerous, but also requires some skill from the driver. Most in a blizzard or ice is sent to public transport or 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 an injection engine in frost
Most often, injection cars do not startat temperatures below -20 degrees Celsius. There may be a lot of reasons, but the main one is the outdated firmware of the electronic control unit. You can get rid of this only by uploading more recent firmware. But there are many other problems that need to be addressed. One of these is the lack of heating in the room where the car is standing. This leads to the fact that the battery fails.
If the battery freezes, thenit is discharged, and since starting the engine in the cold season requires a greater charge than at normal temperature, this is what becomes the main problem. There are several solutions. First, store the battery only where it is more or less warm. Secondly, do not charge the battery to the limit. This is due to the fact that the density of the electrolyte changes, and being in the cold, it loses its properties and the charge drops.
Some more effective ways
It is worth paying attention to the fact that the launchengine in the cold can be done from the pusher, but this applies to manual transmission. There is another way to warm the battery. To do this, you can turn on external lighting for 1-2 minutes, and then try to start the car.
But if it’s not possible to succeed, thenwill have to open the hood and carry out several manipulations already there. For example, you can blow cylinders, which sometimes helps, as well as replace the spark plugs. It should be noted that the launch of the injection engine in the cold for the first time must be performed without the gas pedal. If it did not work out, then after purging the cylinders, you can try to start with the pedal.
Do not forget about the air damper (choke).If you pull it towards yourself, it will be much easier to deal with the problem. In any case, before you leave the car to spend the winter in the garage, you need to check the resource of candles, starting system, oil seals, oil. As for the engine oil for the winter, this is a separate topic for conversation, as will be discussed below.
Starting the carburetor engine in the cold
As for the carburetor cars, then hereThere are problems in the winter. Often this is a problem exclusively in the internal systems of the car. In the very severe frosts, the inability to start the car the first time is a completely normal phenomenon. Most often, this problem is solved by installing contact ignition and its adjustment. But play a role and the launch system, which also must be pre-configured.
Of course, the engine will start in the coldMuch easier if the starter is serviceable. This mechanism can consume much more current than needed, and the output does not give enough voltage to start the car. To deal with this can and should be. It is worth buying a new one or repairing or adjusting an old starter.
Another proven way to helpsolve this problem is to install a more powerful battery. Established battery at 55 Ah can be changed to the one that is designed for 60 Ah. As noted above, the battery should be above average, but not the maximum, this is optimal for starting the engine in cold weather.
How to successfully start up at -20, or choosing engine oil
After we decided on the launchcarburetor and injection engines, it is worth a few words to say about the engine oil, which plays almost a key role. Currently produced the following oils:
- mineral;
- synthetic;
- semi-synthetic (mineral and synthetic).
Mineral oils are used for ICE of the year.release before the 90th. Therefore, VAZ vehicles use mineral oil. But there is one "but." The fact is that such oils thicken at a low temperature and do not allow the engine to be started in the cold. VAZ tolerates semi-synthetics, so it is suitable for the winter period. Do not forget that the model 2101-2107 is often difficult to start due to improperly configured ignition.
As for synthetic oils, they containA large number of different additives, as well as thicken at temperatures below -40 degrees Celsius, so this is an ideal option for the winter period.
Than use of low-quality fuel is fraught
The fuel system of the car is quite complicatedbut, regardless of the brand of car and its service life, high-quality gasoline or diesel must be poured into the gas tank. If starting the engine in winter in a frost is a problem for you, then first of all you need to make sure that the fuel is not diluted with water. After all, if this is so, then in frost the condensate and water will freeze, it disrupts the operation of the vehicle’s systems and makes it difficult to start.
The only reasonable solution to this problem.lies in the fact that it is necessary to drive away the car to a heated place where the water will thaw out along with the condensate. But it is not recommended to go anywhere on such gasoline. There are also fuel dryers that allow you to draw out the remaining 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 a lot of problems that make it impossible to start a diesel engine. Let us consider the main ones, and also find the methods for their solution.
Frustrated fuel injection timing. With late injection, starting a diesel engine in a frost is almost impossible. In addition, it is often quite difficult to determine that this is the case. This will require a diagnosis.
Another topical reason is battery leakage current. If in summer this circumstance may be wrongnoticeably, since the starter consumes not so much energy to start, then in winter this question requires an immediate solution. Most often, problems in the winding (somewhere something short-circuited). All this is found in the elementary visual inspection. It is advisable to check the alternator belt for wear, tighten if necessary. After that, most likely, you can immediately start the engine in a frost without any problems.
Frequent problems and solutions
Consider a few more problems thatmotorists encounter in the winter when you need to leave the garage, and the car does not start. Spark plugs may be cast. This happens quite often, and there is nothing terrible in this, but it is unlikely to go anywhere. You just need to clean the candles so that you can see how the spark passes. They can also be simply changed or calcined on the stove.
It so happens that the car is in the garage for a month, andthe last time it came out was warm, and the so-called “summer” diesel fuel was poured in the tank. In the cold, it becomes like jelly, and the car will not start. To solve the problem, you can resort to the use of auto-chemistry, such as "Quick Start" or something like that. You can warm up the hoses of the fuel system with warm water.
Conclusion
If you are driving on the mechanics, then start in the wintertime must be performed with a fully squeezed clutch. This allows you to reduce the immediate load on the starter. It is also recommended to periodically clean the exhaust pipe from the accumulated condensate there, it is also a working method.
Of course, it is equally important to leave the car onhibernation, having previously prepared it for this. This can be done by cleaning candles, cylinders, etc. As for a diesel engine, it is recommended to start it at the first attempt. Starter can twist about 10 seconds. If the setting did not happen, then you need to look for a solution under the hood.
