2.18. System cooling
Characteristics of the device
The motors of the cars of Hyundai are equipped of the system of cooling of circulation. For the circulation of the centrifugal bomb services cool the liquid. The system of cooling of the motor is composed of a shirt of the cooling, an electric heater with the electric ventilator, the bomb of centrifugal water, the thermostat and hoses. The cooling system works with a wide separate tank.
Management of an outline of cooling the liquid termostático. For the time being the motor coldness, cooling the liquid only circulates in a head of the cylinder block, the cylinder block and the conductor of heat. In the process of the thermostat is heated of the motor it opens a great outline of the system of cooling. The liquid cooling begins to move constantly the bomb of work for an electric heater of system of cooling. The liquid cooling passes by an electric heater of the top I lower it, cooling with the air that passes between electric heater plates.
When the temperature of cooling the liquid is in the variety of 92-97 °C, the thermoswitch lights the electric heater electric supporter. The electric ventilator puts itself in the action for the electric motor and works until the temperature of cooling the liquid does not fall below of 84-91 °C.
PREVENTION
Be careful – the electric supporter of an electric heater can be lit also in the ignition off. In a driving compartment it can happen because of the heat several times.
|
Thanks to the fact that the supporter works mutávelmente the useful power of the increases of motor, the fuel consumption is cut.
The thermostat Beskorpusny of the system of cooling – with a firm thermosensitive enchedor.
Cooling electric heater of tubular system and lamellar, aluminum, with plastic tanks. The liquid cooling is filled out in the system for a mouth of volume of a wide tank which cork supplies with itself entry and end with valves.
Cars with motors with a volume of work of 1,1 and 1,3 l
Check of tension of the system of cooling
Wait until the motor is calmed, then carefully withdraw a cork of electric heater.
Check the level of cooling liquid (it will be in the lowest edge of a mouth of an electric heater).
Install the device of the check of traffic jams of traffic of an electric heater in an electric heater mouth and create the pressure of 140 kPa (1,4 kgfs/cm2) in the system. To support the pressure specified inside 2 minutes, to be convinced of the lack of the hole of liquid of the system, for hoses and connections.
In the presence of the liquid hole they remove us or substitute defective details.
TO OBSERVE
The temperature of cooling the liquid can be very high. Do not open the system of cooling in the hot motor I eat at the same time there can be an emission of hot liquid that will cause burns. There begins works with the cooling system only after cooling of the motor.
|
Shoal they rub the checked knots and the connections of the system of cooling.
In the moment of the removal of the adaptation of experience it looks what from him cooling liquid did not go out.
During the installation, the check and the removal of the adaptation of experience they try not to put out a mouth of electric heater.
Check of a cork of an electric heater of the system of cooling
Withdraw a cork of electric heater, moisten the placing of a cork with the liquid cooling and install a cork in the device of the check (fig. 2.89).
Create the pressure of adaptation until the arrow of the manometer of the adaptation stops turning away.
TO OBSERVE
Pressure of opening of the valve to steam – 78-108 kPa (0,8-1,1 kgfs/cm2).
The very permissible value – 65 kPa (0,66 kgfs/cm2).
|
One secures that the valves opening happens with a not less specified pressure.
If it begins the opening of valves with a less pressure, substitute a cork of electric heater.
TO OBSERVE
Before the check to be convinced of the purity of a cork of an electric heater: if in the placing of a cork there are aspects of a rust or another pollution, the results of the check will be inaccurate.
|
Substitution of cooling the liquid
The liquid cooling must be substituted only after the repair of the system of cooling in which the liquid fused. The substitution inside the annual maintenance is not supplied. If in the moment of the repair the head of the cylinder block, the placing of a head of the cylinder block, an electric heater, an electric heater of a heater or the motor was substituted, to cool liquid anyway must be substituted. There is needed the reason of which in an extra phase I profit from the anticorrosive particles, which it bequeaths to the details of the system of cooling done from leagues from light metal they supply the creation of a lasting anticorrosive layer. The action of anticorrosive particles in the liquid that was in the use is not so big to create a sufficient protective layer in new details.
PREVENTIONS
It is impossible to re-use the liquid of fused cooling – is poisonous. Only it cannot be emptied in the piping or in the land. Use the liquid that cools at places specially distributed with this finality.
In the plum of cooling the liquid look that the covering of the block of the alternation was closed, do not allow the blow of liquid in elements of electric equipment and a painting and covering of varnish of a body. If the liquid falls, at the same time take away his waters of great number while washing.
|
Install the doorknob of switch of temperature in the situation that corresponds to the very temperature of the air given to the hall. One secures that the motor and an electric heater to the touch coldness.
Withdraw a cork of electric heater.
Confiantemente holds tight a cork of drain of an electric heater.
Withdraw a wide tank, fusion of liquid him and install a tank at the place.
Fill out in a tank the water distilled at the level between etiquettes "MINUTE" and I "MOVE", soon glicol from ethylene to an etiquette I "MOVE".
Fill out the cooling of liquid in an electric heater to the lowest edge of a mouth and establish a cork of electric heater, without holding tight it.
Leave and heat the motor before being lit of the electric supporter, the motor work leaves us before not repeatedly to be lit of the supporter.
It gives birth to the motor. Check and if necessary it restores at the level of liquid of standard in an electric heater.
Hold tight a cork of electric heater, soon launch the motor and one convinces of the lack of holes.
The check of the density of cooling the liquid
The cooling system will be completely it during the whole filled year of the solution of glicol of ethylene in the water that prevents the caused damages freezing and corrosion, the formation of hard deposits and, besides, it increases a boiling point of cooling the liquid. In an outline of system of cooling
because of the liquid expansion heating the excessive pressure it was believed what also promotes the increase in a boiling liquid point. The pressure contents itself with the valve in a covering of a wide tank. More loudly to boil point of cooling the liquid is necessary for the normal Repair of the system of cooling. In the too low boiling point in traffic traffic jams the system steam because of what damage of the outline that cools and the reduction of the cooling of the motor are they possible can be formed. Therefore, the cooling system will be completely it during the whole filled year of the antifreeze.
Like liquid that cools only the antifreeze on basis of the glicol of ethylene of details of leagues from aluminum it can be in use.
TO OBSERVE
The level of cooling the liquid is recommended happening in the cold motor how heating his increases of volume and in the heated motor the liquid level can increase considerably.
|
Withdraw a cork of electric heater.
Check the density areometer of cooling the liquid that will be 1,078-1,085 g/cm3.
If the level in a tank will be lower than standard and liquid density on top of the determined one, adds the distilled water. If normal density, to add the liquid of the same mark, that the liquid that is in the cooling system. When the density is lower than the standard, a concentrate restores it.
PREVENTIONS
In the moment of the concentration of the lowest antifreeze of which anticorrosive properties of 30 % of cooling the liquid reduction.
In the moment of the concentration more top of what the resistance of frost of reduction of 60 % and the properties cool of liquid that negatively influences the Repair of the motor. Therefore, it is necessary to maintain the concentration of the glicol of ethylene in the specified limits.
Do not mix liquids they cool of different marks.
