Any modern car that can be found on the country's roads is the most complex mechanism. Due to the correct operation of all its assemblies of the aggregates, the safe movement of the car is possible. Without a doubt one of the main design details is the engine, which is the heart of the machine and an integral part of it. All mechanical processes passing inside the engine, just lead the car in motion. The complexity of the design entails constant control over its normal operation and constant maintenance, which will significantly extend the operation time of the car.

The engine overheated, the consequences of overheating, which parts suffer from overheating

Unfortunately, in the summer period, when the thermometer column exceeds the mark of 30 degrees Celsius, very often car owners face an unpleasant problem, which is called engine overheating. The most problematic in this case is that even one time it is worth over with an engine, as a trace, many different problems will be drawn. It makes the car owner not only to spend a lot of time on solving problems in place with overheating, but most often - repair "flies to a penny."

Despite the fact that the engine during operation is constantly in a hot condition, many parts in it have high sensitivity to elevated temperatures. In the first stages of engine overheating, oil caps of valves may be damaged, which are an integral and important detail of any modern engine. They are made from elastomers, they are most often produced from the rubber mixture based on fluorocus and have a limited resource - approximately 170,000 km. A significant increase in temperature in the engine leads to their rapid wear and failure.

After oil-repellent valve caps, piston rings are damaged, in which the oil-circulation rings from elevated temperatures lose their elasticity. Such mechanical damage will entail a significant increase in fuel consumption and appropriate accelerated wear of engine parts.

but, costs notice, what and this is not sAMI big problem at undesirable exceeding temperature v engine. In time heating occurs gradual extension anyone metal, a he returns to former temperature — comes to normal state. In time strong overheating engine expands those details, which according to designs not exceed installed sizes. Such the effect maybe negative reflect on work engine, night before mechanical damage heads blok., cylinders, a also will lead to «pombok»Cylinders.

Causes of engine overheating

There are a number of reasons that can lead both to the heat of the car engine and its partially or full damage. Overheating can be not only external from the total ambient temperature and the engine itself, but also internal, which entails an additional and more significant danger. If the external is monitored by increasing the working temperature of antifreeze, then the internal often in the first phases is invisible and may manifest itself before it leads to unpleasant consequences.

The consequence of the internal overheating of the car engine is a sharp decrease in its power and the appearance of a noticeable detonation when felting the fuel and air mixture. Any car owner should know some of the symptoms of internal and external overheating and understand that it has led to this.

disadvantage of antifreeze, reasons how to eliminate

Engine cooling system It is one of the main, which allows you to maintain the engine operating temperature as in the summer period (in order to avoid engine overheating), and in the winter period (it allows you to quickly warm the motor and car interior). Often, it may occur so that some factors will lead to a change in the level of coolant in the system. This happens for various reasons, as due to elevated air temperature, intensive engine operation, not the tightness of the system, etc.

It is the lack of coolant in soda that is one of the main causes of the engine overheating of the car and the possible output of it. If the engine cooling system is not completely sealed and has damage, it can be seen visually, by examining it. Under the engine compartment, traces of coolant, or drums on the system itself, consisting of a plurality of nozzles and parts of the design - radiator battery, pump, thermostat, etc. Through small holes at elevated pressure in soda, a large amount of antifreeze can quickly pose.

In the event that it was not possible to visually detect damage to soda, and the level of antifreeze continues to decline, then should be paid to an intricate leakage. In this case, the coolant can fall into the oil or the engine cylinder, which can lead to the hydraulic man and the wedge of the crankshaft of the car.

To avoid these troubles, it is necessary to carry out mandatory maintenance of the car and check the level of fluid in the cooling system. This will significantly increase the resource of the car and save the car owner from trouble.

thermostat does not work, reasons how to eliminate

Thermostat is an important piece of any car, the cooling of the engine of which is due to the coolant. The correct operation of this device allows you to prevent the cooling fluid to enter the radiator battery before the car does not warm up to the operating temperature. Until the thermostat is activated, the liquid in soda moves along a small circle and allows the engine to evenly typing the operating temperature, which significantly increases the operation time of the car. After the engine is heated to 95 degrees, the thermostat automatically opens the path to the radiator.

Since in the thermostat there are some moving elements that close and open the passage of antifreeze from the motor to the radiator, the excessive overheating can lead to the loss of their elasticity. The reason for this is simple - high temperatures accelerate the processes of fluid oxidation and deposits begin on individual elements. The result is that the thermostat will not work when reaching the threshold temperature of antifreeze in the engine. The coolant begins to circulate on a small one or a large circle, which leads to the overheating of the engine, or its bad warming.

To avoid such a breakdown, the car owner should be poured into the cooling system specially intended liquids, as well as soft water, the number of salts and other impurities in which is significantly less.

the radiator does not cooled, the reasons how to eliminate

The radiator is an important part of the engine cooling system. After the thermostat translated the passage of coolant from a small circle to a large, the radiator begins to perform its immediate functions - cooling antifreeze.

One of the main reasons why cooling fluid in soda is coolly cools, is the pollution of the ribs of the radiator battery. Reducing the efficiency of cooling antifreeze occurs just because the radiator is clogged with dust and other garbage that falls from the outside. During the movement of the car at high speed, minor dust with rapid speed is clogged with a radiator, and under the action of high temperatures harden. This leads to a gradual increase in the coolant temperature and later the engine itself.

In addition to clogged ribs, the radiators, one important reason for the inefficient cooling of antifreeze, is a fan that performs the function of additional cooling of the radiator and the hot air intake from the engine compartment. Its malfunction will lead to a deterioration in the cooling of antifreeze.

The main causes of faults in the fan operation is non-working temperature sensor that does not include blowing when the threshold is reached. In the event that the fan is driven by a belt connected to the crankshaft, the entire malfunction can be stored in a break or a weak belt tension.

the engine works with overload for a long time, reasons how to eliminate

Each modern car is equipped with a special device that allows you to track the number of engine speed. This device is called a tachometer and on it, as on other control devices, highlighted with a red zone extremely allowable number of revolutions. In different models of cars, it can vary in different limits.

The long-term operation of the car within the red zone is not recommended by the manufacturer, since it is it can lead to a rapid growth of the internal temperature of the engine. Due to the intensive operation of the motor at extremely high revs, oil starvation may appear, as well as overheating of the pistons. Such overheating for a long time can significantly reduce the engine resource, as well as lead to its wedge due to the expansion of metal moving parts.

In order to avoid overheating of the engine and fails to pay attention to the testimony of the tachometer and not allow it to operate it at extremely high revs for a long time.

long work with detonation of gasoline engine, reasons how to eliminate

Such a phenomenon as the detonation of a gasoline engine is at the present time with the usual phenomenon. Most often, detonation occurs due to poor quality of gasoline, since the octane number does not correspond to the specified manufacturer. Poor quality gasoline burns much faster, plus it will happen to this will be unevenly. In addition to the metallic knock inside the engine, the accelerated heating of the design parts will occur. Such a problem will significantly speed up the engine overheating process and the failure of its individual elements.

In order to avoid engine overheating due to long-term work with detonation, you should refuel the car only on tested automotive gas stations and only high-quality fuel.

the injection and ignition system is incorrectly adjusted, reasons how to eliminate

Another engine malfunction, which leads to a rapid overheating, is incorrect adjustment of the injection and ignition system. Such a malfunction can lead not only to the rapid internal overgeneration of the motor, but also a reduced period of operation of the car.

If the ignition system is incorrectly adjusted, the moment of the beginning of the combustion of the fuel and air mixture and the end time of its combustion is shifted. Thus, the process of combustion of the fuel mixture does not end yet when the exhaust valves open occurs. Such a shift leads to a significant increase in the temperature of the exhaust gases.

Given that the factor that the maximum heating temperature of the cylinder block takes precisely from the exhaust gases, the engine will be much more difficult to cool. The coolant temperature will be very quickly climbing, which will lead to the boiling of antifreeze in the engine cooling system.

To avoid overheating due to such a fault, you should contact the maintenance station on time to adjust the injection and ignition system.

exhaust valve burned out the reasons how to eliminate

A malfunction associated with the burned outlet valve, similar to a problem with an incorrectly adjusted injection system. The blocking valve can be the consequence of the engine operation on the progenit revolutions for a long time.

As a result of the outlet of the exhaust valve through a small hole, gases with significantly high temperatures are completely high. Such a malfunction of the engine of any modern car is fraught with a significant increase in the temperature of the exhaust gases. Subsequently, the temperature of all parts of the engine increases significantly, which leads to a decrease in their operation time.

To avoid boiling the coolant as a result of the exhaust valve, driving at extremely high speeds, as well as track changes in the coolant temperature. On time, the eliminated fine problem will significantly save on the subsequent maintenance of the car.

in combustion chambers, a large amount of Nagar, reasons how to eliminate

Another of the reasons for overheating the car engine is the appearance of a large amount of deposits in the cylinders. Such problems often appear in supported cars with large mileage. The Nagar in the combustion chambers is most often appearing due to the large amount of oil, which comes there due to the production of cylinders and oil-free rings.

Engine oil is poorly burning, so it falls into the combustion chambers and forms the same Nagar. A big problem for the early detection of the upcoming engine overheating is that the engine temperature sensor cannot respond to such changes. The only symptom appearance of Nagara in combustion chambers is a white dum leaving the exhaust pipe.

A gradual increase in Nagar can lead to the emergence of an early or late vibil ignition. This process is very dangerous and in time not eliminated problem will definitely lead to poor consequences. Nagar in the combustion chamber leads to a significant increase in the internal temperature. This may lead to the fact that the fuel mixture will be flammable before the appearance of the spark on the candle. Thus, interruptions in the engine work appear, which leads to the failure of it.

To avoid the appearance of a car, it is necessary to refuel the car with the recommended octane number. This will avoid engine overheating and increase its life.

the engine shirt cooling system is clogged, reasons how to eliminate

Engine shirt is a special cooling system that consists of a channel with antifreeze passing along it. The shirt allows you to cool the head of the engine block and cylinder. It consists of elastic pipes that are suitable for the radiator. There is a hot liquid in it, coolant transfers its heat air, which passes through the core of the radiator.

When the cooling fluid is heated in sod, a high pressure is created, which is reset through a special valve in the roof cover of the radiator. However, if the engine cooling shirt is clogged, then the pressure in the system will gradually rise. Excessive increased pressure in the system will lead to the fact that there will be no possibility of emergency discharge pressure, which will lead to the engine boiling.

To avoid boiling engine due to a scored shirt, it is necessary to carry out maintenance SOD. This will make it possible to get rid of the scale and gradual formation of an undesirable floor on the walls of the elastic pipes of the system.

negative impact of additives, reasons how to eliminate

Another reason for the booster of the engine of any car is to use all sorts of additives that are massively added by car owners in engine oil. Separate types of additives are created on the surface of the cylinders a special protective layer.

This layer for its function resembles deposits and are a good thermal insulator. Thus, instead of cooling the engine, they independently accumulate the inner temperature, the consequence of which will boil the engine.

Signs of engine overheating

Engine overheating is one of the main reasons for his breakdown, which will be able to entail a lot of other more serious problems. There are many signs of engine overheating, which are capable of negatively affecting its performance.

weak overheating, short (10 min) overheating cycle, consequences for the car

Weak overheating is the continuous operation of the engine for 5-10 minutes at temperatures above the working one. This happens after the failure of the thermostat when it does not allow cooling fluid to a large circle, or when the fan fails.

Short-term engine overheating leads to piston boost. However, many models of engines are able to easily withstand the engine overheating. A more serious and long-term overheating of the engine running under load will show themselves with a black smoke of the exhaust pipe. A more tangible sign will also appear - the engine will work as if under load.

The motor will be gradually warm at the expense of large friction of the well-plated engine pistons with aluminum particles, which remained on the surface of the walls of the cylinders.

medium (significant overheating) when the car overheating works more than 20 minutes, possible consequences for the car

If the engine will work over 20 minutes at the exhaust temperatures, the curvature of the GBC, or the formation of small cracks in it, and even extinguishing the gasket is added to damage.

In addition, the special partition on the pistons can completely collapse. Ultimately, medium overheating can lead to gradual oil transmission from various seals in the engine. The result of significant engine overheating can be its overhaul, the cost of which is essential, compared to maintenance.

strong overheating - catastrophe

In case of strong overheating, the breakdown may have larger consequences - a significant knock appears in the motor or it can "catch a wedge". With a strong overheating, the survive may not be far from all the main elements of the engine.

Strong overheating first leads to the fact that cooling stops and the pistons begin to gradually melt and gradually be lit, then small holes appear, ultimately they completely destroy. Aluminum melts and gradually clings to the walls of the cylinders, which makes the stroke of the pistons more complex. As a result, the motor can completely stumble.

The gradual heating of the engine leads to the fact that the oil loses its most important properties and becomes similar to a substance that does not lubricate the details. Next, the high temperature of the liners melted and sticks to the crankshaft, which will lead to difficult consequences. The engine repair with this form of overheating will be long and will require a large cash costs to restore it.

If the engine overheated, what can be done, and what is impossible

It is not recommended to immediately open the hood of the engine compartment, because there is a high probability of being a high temperature steam, while trying to add evaporated cooling fluid into the system. This is not categorically recommended.

The superheated metal with sharp cooling can be deformed, which will lead to a destruction or significant damage to the metal parts of the engine design. Experts recommends, as a result of overheating, stop and let work for several minutes at idle, after which you can drown out a car. If the engine was overheated very much, it is desirable to drown out as it can be used to get rid of overheating faster.

Property Council: How to Prevent Engine Overheat, what to follow

The main rule to prevent engine overheating is the constant maintenance of the car to replace the coolant and cleaning SOD. It is recommended to clean the cooling system using special means that are intended to deliver the walls of the system from unwanted scale and corrosion.

It is prevention that will make the most effective measure to combat undesirable overheating, which will be able to significantly reduce its influence on the engine performance. Preventive work does not require significant costs and allows you to extend the working capacity of the car to a substantially long term.

When carrying out the maintenance of the car, it is necessary not only to replace the waste liquids, but also to inspect the parts carefully in which suspicions are detected. In addition to these rules, you should not forget about the operation of the car - do not move for a long time on low or increased transmissions.

One thing should be remembered - preventive work is less costly than the overhaul of the engine.
