In fact, the engine arises, as a rule, in autumn or in winter, when the engine is difficult to make a turn because of thick oil, and the fuel is not able to ignite in a timely manner in cold cylinders. But, as the automotive practice is evidenced, there are not rare situations when the car does not start at the minus temperatures, but on a heated, recently worked engine.

Perhaps in your practice have also been cases where the engine is hot do not want to start after a stop. Many car owners immediately begin to turn the starter, thereby dischargeing the battery, carefully trying to start a hot motor, which, in fact, should be launched in seconds.

Badly start on a hot car, what is the reason

In fact, the problem is unpleasant, but completely solved. The bottom line is that when the motor works, through the carburetor runs a huge amount of air, respectively, cooling it strongly. This happens with fuel, which also passes through the carburetor. As a result, it turns out that when the motor is running, the carburetor temperature is slightly lower than the motor temperature.

This discrepancy at temperatures is saved only when the engine is running. However, as soon as the motor stops, the carburetor begins to warm through the red-hot motor. Since the air flow is absent, it is heated in minutes to the engine temperature. The remaining of gasoline, while remaining in the float chamber, are intensively evaporated as a result of very high temperatures, filling out all empties, in particular, air filter, intake manifold and carburetor itself. Fuel gradually evaporates, and in the float chamber actually nothing remains. Evaporation, with this, quite often form in the fuel system cork.

The duration of this procedure depends on how much time you will stand after a long ride and on the ambient temperature, about 5 to 30 minutes. When starting the motor in a given interval, will flow into the combustion mixture chamber pereobogaschenie fuel vapors. The consistency will be broken and the fuel is simply starting to pour candles. This is the main cause of a bad engine launch.

Driver actions so that the engine on the hot started well

In this situation, it is necessary to act in a certain order. The main task is to combine the mixture to enable the motor to start, for which when the hot motor is started, it is necessary to squeeze the gas pedal, it is possible and completely depending on the situation, as well as from the carburetor itself.

With a frequent pressure of gas, there is a risk to aggravate the position, since each time you press, the pump will serve a new portion of fuel into the carburetor, and in the end you simply will fool the motor. Make a number of attempts, go out several times after starting and continue moving.

Stalls on hot, why and how to eliminate

No less unpleasant when the hot motor stalls when the vehicle is moving. Such a phenomenon is often observed in the summer, when the air temperature is quite high. The reason for this is the appearance of gas traffic jams in the fuel pump. As a result, the fuel pump functions incorrectly, nothing remains in the float chamber, since it simply does not come to it. This problem is solved by cooling the gas station. To do this, you need to take a wet rag and wrap it with a fuel pump. But this method is relevant only for metal benzonasos. It is not suitable for those models in which glass is applied, as the glass is simply burst from the temperature drop. If, after a long cooling, the hot motor never started, most likely in the machine with a gas station problem. To eliminate the problem, it is necessary to check the gas station. If it is faulty - repair it or replace it.

In addition, the banal cause of the motor stop on the go can be poor-quality fuel or a scored fuel filter. To solve the problem - drain fuel and replace the fuel filter.

The same problem can be with a air filter if it is clogged, the air will not come, respectively, the air mixture will fill the candles. In addition, the motor will be given from the lack of air, in other words, the power will fall, the combustion procedure of the mixture will not be carried out and the engine will be stuck. To solve the problem, you must replace the air filter.

If the vehicle stalls on the go and no longer starts, there may be a problem in the generator. It may not be charged, as a result of which the onboard network will be powered only from the battery, and it is known to be enough for a long time.

In modern advanced cars, the reason may also be in electronics and a variety of sensors.

Tips of professionals

It should be noted that the car may not get on hot and more for other reasons.

1. Sorting battery will not rarely cause the vehicle not start. Therefore, it is necessary to check the status of the battery before traveling.
2. Another possible reason is the problems with the starter. Look, whether the starter turns when you try to start the motor. If it does not react or simply clicks, make it diagnostics with subsequent repair or replacement of the starter.
