Ask why 5+2? And here is the answer: -Nowhere in the car operating instructions will you find the measurement of technical fluids (oil, antifreeze, etc.) in weight units - kilograms, everything is measured in volumetric units, in the European system - these are liters. The average density of the concentrate is 1.13 kg in 1 liter. So, we get: 1 kg of antifreeze - 0.885 l, 1.5 kg - 1.327 l, 5 kg - 4.424 l. And in the repair book it says that our engines have a volume of 5.7 liters. Something like that. To the question: Why red and not the original? I will say that I don’t have time to wait for the original, so I took this one.

How many kilograms are in a liter of antifreeze?

Mass is a characteristic of a body, which is a measure of gravitational interaction with other bodies.
Volume is a quantitative characteristic of the space occupied by a body, structure or substance.

Density is a physical quantity defined as the ratio of body mass to body volume.

The relationship between liters and kilograms of antifreeze is determined by a simple mathematical formula:

V – volume; m – mass; p – density.

In the calculation, the density of antifreeze was taken = 1112 kg/m3.

The density of antifreeze can vary depending on temperature and pressure. You can find the exact density of antifreeze in reference books.

It's no secret that the most important thing in a car is the engine. Its efficient operation depends not only on high-quality fuel and an appropriate lubrication system, but also on the cooling system. And throughout the history of the car, designers have addressed the issue of increasing the efficiency of the car's engine cooling system with the help of.

The mass of machine (engine or transmission) oil depends on the group chemical composition. Its weight is determined by the density of the substance located in a unit volume (kg/m3). The density of the oil is determined with a pycnometer at +20 °C since it directly depends on the temperature - the higher it is, the lower the density of the oil product.

To convert liters (l.) of motor oil into kilograms (kg) or vice versa, you need to focus on the density value, which can be seen in the table (average value) or the characteristics provided by the lubricant manufacturer (exact data). If the temperature of the oil product differs from that provided, then a correction factor is used.

History of coolants (antifreeze)

The first engines of the 19th century were air-cooled.

Around 1900, water-cooled engines appeared.

Since the 1930s, pumps and thermostats have been used for the first time to increase cooling efficiency.

Early coolants or antifreezes were: 1. Saline solutions of sodium and calcium chlorides. 2. Solutions of glycerin, sugar and honey. 3. Methyl and ethyl alcohols.

Since 1930, ethylene glycol has been used for the first time.

Since 1939, special anti-corrosion packages have been used.

History of the appearance of the name of measures

Units of measurement began to appear when they were needed. From the need to know the size of something, from the need for accuracy, people began to come up with measures of measurement that everyone could use. This was the beginning of units of measurement.

First units of measurement

Initially, people came up with the most primitive and most subjective measures. For example, sailors used a pipe as a unit of measurement, the Spaniards used cigars, and the Japanese used a horse shoe. For many peoples, the first common unit of measurement was the arrow. The distance that an arrow can fly was equal to 1 arrow.

The modern sayings “Keep out a cannon shot” and “Keep out a gun shot” appeared precisely thanks to this unit of measurement.

Also, the Greeks, Babylonians, and Egyptians had such units of measurement as stages. One stage was equal to the length of one stadium, which is about 195 meters.

The appearance of a mile, arshin, span, inch

One of the few units of measurement that is still used today is the mile. It appeared thanks to the Romans, Babylonians and ancient Greeks, who often measured distances in steps. A thousand double steps made a mile.

Over time, when people had to measure the length of rope, fabric and other things that were inconvenient to measure in steps, such a unit of measurement as the elbow appeared. One cubit is equal to the length of a human arm from the end of the fingers to the elbow joint. In the same way, arshin appeared, arshin translated from Persian, elbow. It indicated the distance from the tip of the fingers to the shoulder. One arshin is approximately equal to 71 cm.

Lengths in the old days

When it was necessary to measure something smaller than an arshin, another unit of measurement was used - the span. It appeared from the arshin and was ¼ of it. The distance between the spread index and thumb was a span. The span is approximately 18 cm.

The vershok also owes its appearance to the arshin. It was one sixteenth of an arshin or ¼ of a span and was approximately 4.4 cm.

Fathom and its types

In the 11th century, another new unit of measurement of length appeared, which became very popular - the fathom. The length of one fathom was set equal to 3 arshins or 2.13 m. In addition, several more units of measurement arose from it, for example, an oblique fathom was a unit of measurement from the end of an outstretched right arm to the left foot, a swing fathom was the span of the arms on the sides.

From the oblique fathom the Lithuanian cubit appeared; it was equal to ¼ oblique fathom.

Measuring length with a rope

So, let's summarize:

• Stage - 195 meters
• A mile-a-thousand double steps
• Elbow or arshin - 71 centimeters
• span - 18 centimeters
• Vershok-4.4 centimeters
• Fathom - 240 centimeters or 2.13 meters
• Oblique fathom-2.3 meters

Over time, more and more units of measurement appeared, for example, verst, field, tithe, spool, lot, ounce and many, many others, but it was stages, arshins and miles that laid the foundation for modern units of measurement.

Let's look at the length measures currently in use:

• 1 kilometer = 1,000 m
• 1 meter = 10 dm
• 1 decimeter = 10 cm = 0.1 m
• 1 centimeter = 10 mm = 0.01 m
• 1 millimeter = 1,000 microns = 10-3 m

Regarding volume measurement:

• 1 cubic meter = 1,000 dm3
• 1 cubic decimeter = 1,000 cm3 = 10-3 m3
• 1 cubic centimeter = 1,000 mm3 = 10-6 m3
• 1 cubic millimeter = 0.001 cm3 = 10-9 m3
• 1 liter = 1 dm3 = 1000 cm3

Why is a car engine cooling system necessary?

Combustion of the fuel mixture in the engine occurs at temperatures of 2100–2300°C. At this temperature, without forced cooling, engine parts would heat up to a temperature significantly higher than the ignition temperature of the oil. In addition to oil combustion, when the engine overheats, the frictional forces and wear of parts increase, thermal clearances decrease, oil coking and carbon deposits occur, and the filling of the cylinders of carburetor engines with the combustible mixture, and of diesel engines with purified air, worsens.

At the same time, excessive heat removal leads to engine overcooling and a change in the viscosity properties of the oil, which leads to increased wear of parts, a decrease in engine power and efficiency. The ideal thermal regime of the engine is 85-95°C, regardless of its load and ambient temperature.

How much does a liter of 5w40 motor oil weigh?

A liter of 5w40 engine oil whose density is in the range of 867…872 kg/m3 weighs 870 grams. However, this is an average figure, since there are 5W-40 synthetic oils that weigh 910 grams. The final weighing result will depend on the density of the individual brand of oil. The weight of such motor oil in packaging is usually 955 g.

How much does 5 liters of oil weigh?

The average weight of oil in a canister is 5 liters. It weighs 4.55 kg. You can find out exactly how much 5 liters of oil weighs only by knowing the specific gravity (density) of the liquid you are interested in. For example, motor oil with a density of 910 kg/m³ weighs exactly 4 kg 550 grams without taking into account the weight of the canister itself. Sunflower oil will be heavier - 4.65 kg because it has a density of 0.930 kg/l.

What to do?

• Use antifreeze that meets your vehicle manufacturer's specifications.

• If you bought a car and don’t know what was poured into it and when, it is better to replace all technical fluids (oil, antifreeze, brake fluid).

• To add, use the same brand of antifreeze. Different manufacturers may use incompatible additive packages.

• Whatever the perfect antifreeze, it is necessary to regularly monitor its level according to the marks in the expansion tank and the concentration using a glycometer, due to the formation of condensation, possible leaks and evaporation, and also replace it within the time specified in the instructions for the car by the manufacturer .

How to dilute antifreeze concentrate?

All information is on the label. If information is missing or unclear, remember the following:

• Never pour concentrate pure without dilution. You will receive antifreeze with a freezing point of -13°C and a strong corrosive effect.

• It is not recommended to use antifreeze with an ethylene glycol content of more than 67% and less than 30%. Common dilution: 33% ethylene glycol and 67% water (1:2) will give you -17°C. 50% ethylene glycol and 50% water (1:1) will give you -36°C. 55% ethylene glycol and 45% water (1 ,2:0.8) will provide –40°C. 65% ethylene glycol and 35% water (2:1) will provide –65°C.

Answers from forum users and experts to the question: How to convert 1 kg of lubricant into liters

If you are a manufacturer and you cannot find buyers or simply sell silicone lubricant for export, read it, you will learn a lot of new things.

01/06/2016

If one kilogram of water contains one liter of it, then with respect to other, denser liquids, this is difficult to say. For example, a liter of paint contains 1.2 kilograms. As for lubricant, 1 kg of lubricant will be approximately 0.87-0.93 liters. Usually this data is indicated on the packaging of the substance, as this is important information.

ATTENTION!

Ethylene glycol is a strong poison. If ingested, it causes severe intoxication, damaging the central nervous system and kidneys. The lethal dose for an adult is 100 ml. The problem is the sweet taste, which can attract your children and pets. We do not have statistics on ethylene glycol poisoning for Russia, but in the USA, where this problem is taken under separate control, over a thousand cases of fatal poisoning are reported annually. Avoid contact of ethylene glycol with skin. We strongly recommend that you store antifreeze, like all technical fluids, out of reach. Spilled antifreeze should be immediately removed with a rag or sand and then disposed of. Getting ethylene glycol into soil or water also poses a threat to plants and fish.

To ensure environmental safety and eliminate cases of poisoning, propylene glycol-based antifreezes are used. Propylene glycol has long been used in the production of food, medicines and perfumes. In heating systems for residential premises and food production, according to European standards, only propylene glycol is allowed to be used. Most municipal transport in Europe has switched to propylene glycol. Propylene glycol, unlike ethylene glycol, is less aggressive to metals and has greater thermal conductivity.

Personally, I believe that liquid engine cooling is much better and more progressive than air cooling (the facts show this, now 99.5% of cars are equipped with it). But antifreeze or antifreeze do not last forever and they simply need to be changed after a certain interval (usually 3 - 4 years). And then you may have a question, how many liters of this liquid are in the cooling system? And you know what (while I was writing this article), another question arose - why exactly such a volume, as they say, no more and no less? In general, the article and, as usual, the video at the end will be interesting, so read and watch...

Why use oil conversion in kg?

Our online calculator for converting kg of oil to liters will make it possible to find out the weight of one liter or more of motor oil, and will also allow you to recalculate the weight in kilograms or tons of any other type of oil, fuel and other fuels and lubricants. Or, on the contrary, understand how many liters of raw materials should be at a certain weight.

Such a transformation may be needed not only for reporting in organizations involved in fuel and lubricants or transport companies, but also for ordinary car owners. How?

As an additional indicator of the need for an oil change. After all, the weight of one liter will change by 4 - 7% during wear and tear over 1-2 years. And if you focus on the average density, then by weighing still fresh oil you can determine its quality. Low-quality motor oil may contain harmful additives, due to which it will have increased density and, accordingly, more weight. Or vice versa, due to an insufficient amount of additives for a particular type of oil, the mass will be less than it should be according to the characteristics specified by the manufacturer.

And also, knowing the fact that the volume of oil increases when heated, some suppliers, when filling cans on the packaging line, heat the lubricant and pour it according to the volume, rather than weighing it. As a result, the canister of oil on the counter will stand compressed and several grams lighter, because, in fact, it will not be topped up. An individual buyer will not notice a shortage of a few milliliters, but on the overall scale of production, the difference is significant. Therefore, by weighing such oil and using a conversion calculator, it will be possible to identify such a deficiency.

Why change antifreeze at all?

The thing is that antifreeze or antifreeze itself (this is a Russian, or rather a Soviet invention) becomes unusable over time, and if you don’t want your radiators, pipes or hoses to corrode, you must change them!

What and how does it corrode? Just a few words for understanding - look, coolant consists of three main components:

• Ethylene glycol or propylene glycol (less toxic and used in the G13 generation). These are simple dihydric alcohols, very active and, with prolonged exposure, can destroy metals, rubber, etc.
• Distilled water
• Additives. They are needed mainly only to neutralize the negative effects of ethylene glycol and propylene glycol (to put it in simple words, they prevent them from corroding everything and everyone)
• Well, the last thing is dye

Well, actually, why do you need to change? YES, just after 3 - 5 years the additives wear out and stop working, that is, the liquid that is poured inside becomes VERY active.

How much antifreeze is in a VAZ-2110 8 valve injector

Car : VAZ-2110. Asks : Stas Salomatnikov. The essence of the question : I want to completely drain the antifreeze and flush the system, how much antifreeze should I buy?

Yesterday I looked into the coolant reservoir and was horrified, there was some kind of dirt and foam. In the winter it’s still normal, but in the summer it will be a mess. The honeycombs on the radiators will get clogged, so I don’t want to force the car. I want to completely flush the cooling system and replace the antifreeze.

How much antifreeze does a VAZ-2110 need in general? My car has 8 valves.

Features of Antifreeze

Antifreeze is responsible for cooling the engine. Without it, the engine will not be able to operate normally, as it will simply overheat.

Antifreeze is sold in cans of various capacities.

Therefore, every VAZ-2110 owner needs to know how many liters of antifreeze should be in the car, and when it needs to be changed in order to ensure normal functioning of the internal combustion engine.

The following two tabs change content below.

Timely maintenance not only guarantees the durability of the vehicle, but also makes it possible to save on repairs. The situation is the same with antifreeze.

High-quality antifreeze must meet the requirements of GOST.

Advantages

1. It does not expand like water when heated and boils at a higher temperature.
2. Doesn't freeze in sub-zero temperatures.
3. Doesn't foam.
4. Does not corrode metal and plastic.

How much antifreeze is needed in a VAZ-2110?

A car of this brand will need to be filled with about 7-8 liters of liquid.

It is recommended to purchase antifreeze from trusted manufacturers.

This will ensure normal cooling in the system. Sometimes when pouring it may seem that 5-6 liters . But that's not true. Antifreeze cannot immediately fill the entire system, and therefore it must be filled correctly.

After pouring antifreeze, you need to let the engine idle for some time. Then open the expander plug and add fluid to the system. Topping up should be done with the engine turned off, when it has cooled down.

If there is little liquid in the system, it will boil faster and will not be able to fully cool the engine . It is also important to monitor the excess fluid in the system. In this case, it may tear the pipes or the tank itself. There are usually marks on the tank with the minimum and maximum antifreeze points in the system.

The antifreeze level in the expansion tank should be between the MIN and MAX marks.

Draining antifreeze

In the VAZ-2110 it should be changed after a mileage of 150,000 kilometers.

Typically, antifreeze is changed every 5 years or after 150 thousand kilometers.

It is not recommended to exceed this figure. But sometimes in practice it may be necessary to replace antifreeze prematurely. This should be done when:

1. The fluid in the reservoir has a film of oil.
2. There is rust in the liquid.
3. The engine often boils.
4. There is a fluid leak.

Antifreeze is changed ahead of schedule if it has darkened, but first the cause is established.

Recommendations

What should you consider when replacing antifreeze? To carry out filling correctly, you must adhere to the following rules :

1. Fill in the brand of antifreeze that was previously in the system.
2. Give preference to a quality product from a reputable manufacturer. This way you can increase the service life of the motor.
3. Filling should only be done into a cold engine.

Before filling in new antifreeze, it is recommended to flush the cooling system with special cleaners.

conclusions

Based on the above, you were able to find out how much antifreeze you will need to pour into the VAZ-2110 system, as well as how and when to do it correctly. If you apply the recommendations given in the article in practice, you can ensure uninterrupted operation of the internal combustion engine .

How many liters are in the system?

Well, now the most interesting thing is how much antifreeze is needed. I will provide a breakdown of several popular brands and models:

VAZ. In older versions (2101 - 2107) it was about 8.6 liters . Fresh front-wheel drive versions (PRIORA, KALINA, GRANT 2109 - 2115) - 7.8 liters

RENAULT. In particular LOGAN (SANDERO) – 5.5 – 6 l.

KIA ( Hyundai) . In particular, let's talk about RIO (Solaris). It all depends on the engine size: 1.4 – 5.5 liters; 1.6 – 5.8l

Daewoo . In particular NEXIA. Engine 1.5 (8 valves) – 6.2 liters, 1.5-1.6 (16 valves) – 6.7 liters.

If we take the arithmetic average for various brands and brands, engines with a volume of 1.4-1.6, it turns out from 5.5 to 8 liters . In any case, you need to buy two 5 liter canisters. There will still be left for topping up (and you’ll also flush the system a little)

BUT this is what interested me, and I think you will too. Why exactly so much antifreeze or antifreeze, that is, say 7 liters, and not 3 or 10 liters? Why such a volume? And there is a completely reasonable explanation for this.

About the airlock

Having found out how much antifreeze you need to fill in the VAZ-2110, you should also talk about the air in the system. It can enter when new fluid is added to the system. Therefore, we adhere to short pauses so that the antifreeze smoothly leaves the space of the tank. You can’t pour it in large portions up to your throat, splashing everything around. How much antifreeze should I pour into a VAZ-2110? The answer is 7.8 liters.

• Place the front of the vehicle on a hill.
• Open the tank lid halfway.
• Start the engine and warm it up to operating temperature.
• Turn off the engine and use gloves (carefully - it’s hot) to squeeze the upper and lower pipes that come out of the radiator.

Thus, we will displace the air from the system as much as possible. Its presence is extremely dangerous for the engine. Air can easily lead to overheating.

Subtleties of cooling

To understand how much antifreeze is needed in the cooling system, an engineer needs to calculate many different parameters. Several problems are solved:

• To prevent the engine from overheating, the coolant does not boil over the entire load range (both at idle and at maximum speed). Effective removal of thermal energy from the motor (so that it does not jam)
• It is necessary for the liquid to warm up relatively quickly; it is important for winter so that you do not freeze in the car. Also, various components in the car are heated for more stable operation (for example, the throttle)

Therefore, there should be neither too much nor too little antifreeze in the cooling system, but enough.

In order to calculate correctly, we first need to take such an important parameter as the efficiency of the internal combustion engine , and we will understand that this is not such a large percentage, only 20 - 25%

And the rest goes to mechanical and thermal losses (they are what we are interested in).

Approximately 30% of energy is lost to heating. That's a lot!

We will count them based on the engine power. It is usually indicated at peak (that is, at maximum speed, say 4000 - 6000, different for different manufacturers). Often you just see power of 100 - 120 - 150 - 200, etc. Horse power

For convenience, let’s take a 100 hp engine. and convert the power to KILOWATTS. For this, 100/1.36 = 73.55 kW (1 kW = 1.36 hp). Once again, you need to understand that this power at maximum speed

As a result, 73.55 X 30% (this is exactly how much is spent on heat losses) = 22.065 kW, rounded to 22.1

Just think about it: 22.1 kW is spent on heating, and it just needs to go somewhere. By the way, from this indicator you can safely subtract about 9 kW (40%) that fly out into the chimney with exhaust gases.

We count further. For example, let’s take that our motor is made of aluminum and weighs 100 kg. In order to heat aluminum, we need to apply 3.9 X 10 5 = 390,000 J per kilogram. If we convert all this into kW, we get 0.1 kW per kg , multiply by 100 = 10

Thus, to heat a motor weighing 100 kg, we need 10 kW of thermal energy.

A standard car radiator dissipates about 2 kW of heat in a quiet state, and about 3-4 with airflow. At extremely low temperatures, dissipation increases. It is worth noting that the car also has a heater radiator (pipe pipes, etc.), in a quiet state it dissipates about 0.5 kW; when blown, it can provide 1 to 2 kW of heat into the cabin.

So what's the bottom line? 22.1 kW (maximum heat). We subtract 10 kW to warm up the engine, 9 kW goes into the exhaust pipe, about 2 kW for the main radiator + 0.5 kW for the heater radiator. 10 + 9 + 2 + 0.5 = 21.5 kW.

We need to remove about 0.6 kW more, we also need to use the radiator, because without liquid it will not work.

Replacing antifreeze on a VAZ 2107

Antifreeze replacement in domestic VAZ 2107 cars is carried out at standard intervals - once every 2 years or after 60,000 km. It all depends on which condition is met first. In addition, the fluid must be replaced if it has changed color, for example, acquired a reddish tint.

Which antifreeze is better, and how much should I fill it with?

Before draining the antifreeze, you must decide on the brand of new coolant and purchase it in the required volume. VAZ 2107 cars require 9.85 liters to fully refill the cooling system. This means that one 10-liter container of antifreeze will be enough. When purchasing coolant, please note that some antifreezes are sold in the form of concentrates and require dilution with distillate in a 1 to 1 ratio.

To replace antifreeze, you can use the following types:

• For “sevens” from 1998 to 2002, the optimal coolant option is G12 red. This includes MOTUL Ultra, Lukoil Ultra, Castrol SF and others.
• In VAZ 2107, manufactured from 2003 to 2012 and beyond, it is recommended to use G12+ or G12++ antifreeze of the following brands - MOTUL Ultra, Castrol Radicool Si, Zerex G.

Before draining the antifreeze, stock up on the necessary tools. You will need a minimum set, which includes a key for “thirteen”, a group of screwdrivers, a container (this is where the old coolant will be drained), as well as 10 liters of the new composition in a canister.

Replacing antifreeze begins with draining the old working fluid. To begin, find a flat surface to perform all manipulations. It is better to work on an overpass or pit, in a garage. If it is not possible to park the car level, the front part can be raised slightly higher than the rear (the reverse situation is excluded).

Then proceed like this:

• If present, remove the engine protection. To do this, just unscrew the twelve fastening bolts. Also remember that there are four plastic fasteners.
• Go to the salon and move the lever to the right, which is responsible for the release of warm air from the heating system in the car's interior. As a rule, it is located on top.
• Open the expansion tank. Assess the condition of its plug and, if there are defects, replace it.
• Open the filler neck at the top of the car's radiator.
• Unscrew the plug that closes the coolant outlet from the engine cylinder block. Before draining the antifreeze, place an empty container (bucket or bottle) to remove the old coolant.
• Move the container or place a new container under the radiator, then open its drain. Wait until the old coolant is completely out of the system.
• Discard the belt that holds the expansion tank. Now lift the tank up to drain the antifreeze from the connected tube. The remaining coolant, in this case, exits through the drain in the radiator.
• Leave the car for a while to ensure that the coolant has completely drained out.

Filling with new antifreeze

Now proceed to replacing the antifreeze. To do this, proceed like this:

• Return the cooling system reservoir to its original place and screw the plug onto the drain hole of the VAZ 2107 cylinder block. Do the same with the drain plug on the radiator - screw it into place.
• Pour new antifreeze into the radiator, and then do the same work for the expansion tank. Monitor the position of the coolant in the system using the control marks. Stop pouring antifreeze when the line is 3-4 cm above the MIN line.

Removing air from the system

Now remove any air pockets from the system. To do this, find the outlet, bypass and supply pipes of the radiator, and then press them several times with your hands.

You can do it differently. Park the car so that the front is higher, start the engine and let it run for 5-6 minutes at idle. Now return the radiator and reservoir caps to their original places. After starting the engine for the first time, check the coolant level in the tank again. If it is not enough, top up.

Finally, consider the following points:

• Replacing antifreeze should be done exclusively on a cold engine.
• Remember about the toxicity of coolant, so work should only be done outside. All manipulations can be performed indoors, provided there is good ventilation.
• Three days after the replacement, check the antifreeze level again. If necessary, bring it to normal.
