Heated engine cooling system. What engine preheater is the best. Electrical Preheater HEAT

In place of unsafe methods of warming up the car with open sources of flames and the soldering iron lamps have long come preheater Engine. This unit allows you to warm it before launching the engine during the cold season, as well as heat the air in the cabin and defrost windshield. Thus, the heating device is allowed to increase operational deadlines power aggregate. Patented aggregates operate in temperature from 0 ° to -45 ° C.

Features of the device

Preparation heaters for vehicles are small devices, the purpose of which is pre-heating the motor without starting it. Also, thanks to this device, heating the cabin, defrosting windshield, janitors.

Principle of operation of any device

The design of the device includes the following details:

• fuel pump;
• heat exchanger;
• thermal chamber;
• circulating liquid pump;
• fuel drive.

The purpose of each component of the element of liquid preheaters is one - the run along the cooling system of the heated coolant for warming up the engine.

In addition to these parts, the configuration is provided for the presence of a thermal, activating the functioning of the built-in fan, the electronic control module, the switch.

Installation of the device is carried out in the cutting space of the car. Install the preheater is easy enough:

• the heat exchanger is attached to the small circuit of the cooling system of the motor;
• the electronic module is joined by the electrical network of the car.

Despite the ease of installation, this case is recommended to entrust a certified specialist. The case is in guarantees, it will stop if the installation will be engaged in a person who does not have permission or the relevant document on these work. First of all, these nuances relate to the products of Russian production.

Varieties of devices

It is difficult to overestimate the need for a heater for the car used in the Russian winter climate. Especially popular apparatus will be for diesel enginesWhen, when a decrease in temperature, the fuel acquires a thick jelly-like consistency. But for owners of cars operating on gasoline, the device will also not be superfluous. The unit facilitates the first institution of the motor in cold conditions and will warn it from the ambulance.

Electric 220V.

Electric engine preheater does not apply to class autonomous devices. The device is fixed instead of one of the cylindrical motor bolts, and the device operates only when connecting to a voltage source with a voltage in 220 V. Most of the modern cars already have a given addition in the configuration, but as a rule, it is characterized by a reduced power, which causes car owners to accommodate Another device.

This type of preheating heaters in the northern countries, such as Canada, Scandinavia, and others, are that infrastructure is a bit better developed in European republics than in Russia. There, almost every parking has separate outlets, which is so necessary for the operation of the unit.

Equipment for passenger cars has a complex design, which includes:

• heating element with a power indicator of 500-5000 W;
• the electronic unit control equipped with a timer;
• battery charge module, if available in the configuration;
• fan - needed to heal the cabin or the increasing area;
• pOMP - is not present in all modifications and is used for enhanced circulation of the coolant for uniform warming up.

It is not difficult to figure out how the preheater works is not difficult - the principle is based on the simplest laws of physics, when the warm liquid due to the temperature difference begins to circulate through the highway.

Heating element of the preheater diesel engine transmits the thermal energy of the fluid, at the moment when it circulates through the system. In this case, the TEN is mounted in the lower area of \u200b\u200bthe cooling system so that the heated antifreeze rose up, and the cooled down down.

If the package is provided for the presence of a liquid pump, the installation site is not fundamentally.

Offline Preheaters

Autonomous engine preheaters are mounted in the open space of the car and function using the following spray varieties:

• petrol;
• diesel;

The design of the autonomous preheater of the engine includes the following details:

• control module controlling temperature regime, fuel supply level, oxygen, gas;
• fuel pump;
• oxygen supercharger;
• miniature boiler with built-in combustion reservoir;
• liquid pump;
• perhaps the presence of a relay, timer, device DU or other.

The principle of operation of the preheater is a few steps:

• the system is included in one of the ways of launch;
• the fuel pump is triggered transmitting gasoline, dt or gas to the combustion chamber;
• ignition Candle contributes to the ignition of the incoming fuel;
• the flame heats the coolant;
• the coolant circulates through the system due to the pump operation.

When the temperature of the antifreeze reaches the desired indicator, the fan is started in the auto cabin. On average, the consumption of fuel when applying an autonomous liquid preheater is 500 ml / h.

Minuses of the device are concluded big flow Electricity. And since the device operates from the battery of the car, there is a chance that it can be completely discharged in the morning.

Thermal battery

This is a fairly new invention that can be contemplated in such a model of cars as Toyota Prius. The device is a thermos in which the desired volume is accumulated with a heated coolant. At the time of starting the engine, this fluid enters the cooling system, which gives a little dilute cold antifreeze or antifreeze.

In general, in this way it turns out to increase the temperature of antifreeze by 10-20 ° C. This allows you to operate a car without a special load on the engine.

Such batteries can hold heat to two days. The ineffective, but very convenient method of heating the motor does not require the use of fuel or electricity.

The best models of engine preheaters

To accurately decide which engine preheater is better, it is recommended to compare devices of the most popular brands.

The most sought-after brand, since the devices of this manufacturer are able to warm up not only the coolant, but also the motor, salon. German modification TERMO TOP E is a liquid apparatus equipped with a timer.

At a temperature of -15 ° C, the unit regularly performs functions for no more than 25 minutes. The main minus of the device is the price that is 40,000 rubles.

The aggregate of the domestic manufacturer may warm the coolant and the salon. The configuration provides for a remote control functioning within a radius of 150 m. The main disadvantage of this is the absence of feedback. If you know more, then when the heater fails in the work, the driver does not know about it until it detects that the car simply does not start.

Manufacturer satisfied special attention The security system that controls the process of functioning the entire device. When a malfunction is detected, the device will report this to the owner of the error code.

Severste 103-37-41

A non-autonomous unit operates only from voltage in 220 V. The device is equipped with a thermostat. Heated to a temperature of 60 ° C requires one hour of operation of the equipment.

The benefits of preheating

Professional drivers have not been questioned for a long time due to the obligatory equipment of any car by the engine preheater, regardless of the variety of the latter. And if in Europe this type of equipment is used for more than 20 years, then in Russia only now he began to acquire a massive character. Previously, it was used mainly drivers of heavy trucks and diesel cars.

The benefits of PPPD is unconditional for the motor itself, and for the driver, in particular, fatigue is reduced, the comfort of operation is improved, the need for daily "witchcraft" in the form of soldering lamps, rechanged batteries And other manipulations.

The most important thing is that the device increases the operational resource of the car - one cold Start The engine is equal, on average, 100-120 km run in the warm season.

So, if you briefly describe the pluses of PPPD, you can form the following theses:

1. Reducing the volume of fuel consumed. On average, for the winter, cars run 300-500 times depending on the type of work. One cold launch Consumes up to 500 ml of fuel, respectively, only for 3 months of winter you can save about 150 liters of fuel (5500-6000 rubles.).
2. Reducing the load on the power unit. More than 80% of the load on the engine falls at the time of its cold start when the viscosity of the oil is very high, it does not have time to lubricate the parts in time, respectively, the friction of movable parts occurs dry. On average, one cold launch corresponds to 100 km run in normal conditions. Considering the fact that they are over 300 for the winter, it is easy to calculate which kilometer "wins" your car is just in one season.
3. Increase operation of operation by car. At minus temperatures, human heat transfer increases. Its clone is a dream, the fatigue increases, attention is scattered. All this is a straight road to an accident, when it is impossible to react to risk in time. Warm salon, clean windshield, heated seats - a deposit is not just comfortable, but a healthy driving at any time of the year.

Pipe electrical heaters

In addition to blocks, which are mounted directly into the block, there are no pipes installed in the incision of the nozzle.

Such a heater is suitable only if the diameter of the nozzle corresponds to the diameter of the device.

There are also pipes in the manufacturers of start (M1 / m2), Defa and Calix. They are also not difficult to install their own hands.

Such modifications of the pipes of the preheater are suitable only for the domestic car domestic VAZ, UAZ and gas.

Remote heating devices for cars

One of the types of electrical heaters is remote. The design is more complicated than in previous species. The kit includes hoses, clamps, thermostators.

Marks of domestic remote prehea heaters Severs-M (1-3), Alliance, Severste +, Atlant Smart, Atlant + and others.

Analog foreign production Hotstart TPS (SHOTSTART), as a rule, is already full of regular cars. The cost of it is about 8 thousand rubles.

There are models with forced circulation of coolant. All previous variants of electro-heaters of motors had a natural circulation.

American Hotstart worth about 25 thousand rubles. Russian analogues with forced circulation cost much cheaper, about 2.5 tr. These are Atlant, Atlant + and others.

And, as not to mention the world-famous Chinese manufacturers - this is Xin Ji, the capacity of which is not more than 1.8 kW.

Heating plates

Picklight the ability to warm up the engine with special heating plates. They are installed mainly on the body of the cylinder block and on the crankcase.

Principle of operation of heating plates like electric tannes. There are models that work from the network 220V with a frequency of 50 hertz, there are and operating from 12 volts.

Power range of plates from 0.1 to 1.5 kW. Temperature mode from +90 to +180 degrees.

Installation with your own hands is also possible. After selecting a place to install, you need to clean from dirt and degrease this place and glue the plate.

Important! Heating plates can not be heated battery.

Such heating elements will not be able to quickly heat the coolant and the engine, they are designed to work in a long time.

Advantages of heating plates for DVS:

1. Reliable and durable. Do not require repair. The warranty period is long.
2. Easy mounted. No need to contact the installation service. Included there is a sticky tape that must be glued to peeled and skimmed space.
3. Safe. Vedo- and dust-proof increase the resource of the plates.
4. Resistant to wear. No moisture is afraid. Plates have a protective layer.
5. Efficiency. Electricity costs are less than the cost of fuel (gasoline, diesel fuel).

Disadvantages of heating plates

1. High cost of such an engine heater.
2. When nutrition plates from car battery (AKB), it is exposed to elevated wear.

The distribution of preheating plates is due to the fact that their use is very convenient.

Output

Having studied the advantages and disadvantages of heaters, we see that better autonomous heaters. Therefore, if there is a financial opportunity, it is better to install a reliable autonomy right away. Among electrical - comfortable lamellar heating elements.

On the video test of the popular engine heater Vibasto.

In the Fundament of Winter, many car owners began to think about how better to prepare their own vehicle. Basically, all such preparations are reduced to a banal replacement of rubber, oils, rechargeable battery (either of its recharging) and other "cosmetic" events. However, few people decide to approach this issue more thoroughly, and in vain ... After all, if, for example, the engine engine will not start because of a strong frost, new tires And the battery will not help you leave the parking lot or poorly insulated garage.

Considering this fact, it is not at all superfluous to pay your attention to such a device as an engine preheater, as in any weather and under any circumstances it is it can provide fast, and the main trouble-free start of the motor. Of course, it is best to purchase a similar device in the finished form, as they say "from the manufacturer", but if you wish and the presence of skillful hands, you can make it alone, let it sound a little unreal. In any case, the main thing is to delve into the details of the work and deal with all possible nuances, and then - the case of technology, would be instruction. Just about this we will talk to you today, but for a start a little theory ...

1. Cured path: Soldering lamps - modern electric preheater

As you know: "All new is a long-forgotten old", although I personally would have changed a little this statement and instead of the word "forgotten" would use the concept of "improved". But it is so it is, many modern devices have a very interesting history of their development. To which our ancestors were not thought of: an iron iron on coals, the first car resembling a cart with a motor, etc. In this regard, it did not exception and the aforementioned preheater And if you turn to the story, you can detect many interesting factsassociated with this device. For example, do you know that "Praded" modern designs It is the most common soldering lamp, an alternative to which (at that time) was except that no less well-known kerosene (the so-called "kerosene"). It is their grandfathers and great-grandfathers that were so deftly used in many areas of their livelihoods.

Of course, those functions and opportunities that have named devices possessed cannot be compared with powerful functional characteristics and numerous advantages of modern equipment, but with their task they still coped and since this was more or less enough, it means you need to give them a well-deserved place in history . Modern engine preheater, in our time, is used to facilitate the launch of the motor under conditions of low temperatures, and in some cases, also to warm the air in the car.

Regardless of the type and model, all heaters perform approximately the same functions, responsible for heating and maintaining the coolant temperature of the vehicle (antifreeze or antifreeze) in the desired range. In addition, the device described allows to significantly reduce the fuel consumption, because the engine mandatory warming is much less time. But the most important advantage of using is more quality protection Motor block resources, respectively, increases its life.

If you disassemble the types and possible varieties of heaters in more detail, it is worth noting that absolutely all devices are classified using a certain, single schema. Based on what, the following main models are distinguished:

- gas heaters;

Devices using liquid fuels;

Heaters, the nutrition of which occurs exclusively from the external source.

As for the last species, it is precisely the electric preheater of the engine considered today.

2. The principle of operation of the electrical preheater

Electric type heaters include non-autonomous devices, even for their operation, it is necessary to supply networks (220 V). Now we will understand in more detail in the principle of their work, but to start a little interesting facts.

Did you know? The first inventor of the motor heater is considered to be Endrew Freimen (Andrew Freeman), which in 1949 received a patent for a coolant heater capable of screwing into place of one of the cylinder bolts. IN modern world, Electric type heaters are widespread in the northern countries of different states (Russia, USA, Scandinavia, Canada's cities), since it is here that there is a sharp need. Moreover, automakers of these regions include them in standard complete set Available cars, and sockets needed to connect devices can be found on many multi-storey parking lots and car parkings.

The existing electrical heaters today are a whole system that consists of several important parts. These include:

- electronic control unit having a built-in timer; Battery Battery Requal Body;

Located in a hermetic heat exchanger, the heating element with a capacity of 500-5000 W (installed in the process opening of the cooling shirt, or it is connected to it using nozzles);

Fan heating for heating salon.

In some models, in addition to the elements listed, there is still a built-in pump, the main task of which is fast and uniform engine warming up.

The standard electrical heater is represented as a spiral device, which is inserted into the motor cylinder block and operates from the external power grid of 220 V. in the role of the main executive element, there is a small electric spiral. In the course of its installation in the block of cylinders, the anti-low plug is removed from it, and the named item is installed on its place. When through a spiral, under the action of high voltage passes the current, it begins to heat the coolant (). The circulation of fluid in the system, passes due to natural convection, although it is less productive than artificial movement using a pump (also spend more time). The most famous representatives of the preheater of this type have models Defa Warmup.

If you store your vehicle in the garage or in the parking lot equipped with electrical sockets, the use of such a device will be as if it is impossible, otherwise it is impossible to apply it (when parking under the windows at home, you just have nowhere to connect the heater, which means that it does not will be). Also, a minus use is strong "voraciousness", and the electricity is not cheap today. It would seem that manufacturers have provided this drawback and completed the heater with a special timer, allowing you to install the required fluid temperature (when crossing the installed face, the spiral is turned off or turns on), but in practice it could not fully solve the problem.

The standard Options of the engine electrical heater include:

- charge battery;

Warming up the working fluid;

Heating of the cabin by supplying thermal air through the stove.

In general, the operating principle of the electrical preheater of the engine is the same as in the autonomous system - also, through the heating of the coolant, heat transmission is carried out by the power unit. The main difference lies in the method of heating (using an electrical power source), which makes it possible to apply an additional function - charging the battery, and in winterWhen low temperatures contribute to quick discharge, it is not possible by the way.

3. Engine preheater with your own hands

If the preheater of the motor is not included in the staffing of the car, but you would really like to have a similar device - there is nothing impossible. The easiest option is to go to the auto parts store and choose a suitable model (there should be many problems with the installation, especially since the appropriate instruction should be attached to the device). However, there is another path that provides for the independent manufacture of the desired device. The time will leave more, but having done everything with your own hands, you can be confident as a finished product, plus save some money.

And so what to create an electric preheater, you will need simple materials that are "in the farm" from any car owner, this is:

- Incandescent helix (called by Tan), is suitable even from some old kettle;

Metal tank;

Fitting (sold, probably in every plumbing store);

Distribution box (can be found in the electrician store).

Now, armed with elementary knowledge from the field of electricians, mount the device, which should provide high-quality preheating of the power unit, saving fuel and maintain the functionality of the engine for a longer service life. Getting started directly to action, it is necessary to understand that the task is not distinguished by simplicity, which means the whole process (both manufacturing and installation) is likely to be accompanied by some difficulties and specific nuances.

Compared to factory (factory) products made by hand, it will not be clearly and perfectly placed in motor compartmentSo all measurements must be carried out with an accuracy of a centimeter. However, it is not necessary to regard the specified possibility as an insurmountable obstacle, especially if there is a lift in the garage or looking Yama. If they are not (which rarely, but happens), then, most likely, you will not be able to independently place all the necessary wires and electrical equipment, since the space under the car will be limited and climb hard. Also, I want to warn about the risk of making a homemade heater, because one incorrect movement and you can get serious engine problems.

4. Installation of electrical engine preheating

Suppose you have a ready-made (purchased) set of an electrical preheater and you decided to install it yourself. In this case, at the initial stage, you need to evaluate the space existing under the hood and decide where the device will be mounted. It may be a place under, metal parts of the tunnels or a place next to expansion Bachkom cooling system. The last option is more relevant in the case of an installation on an SUV, which often moves through the swampy terrain. Also, do not forget to check the prepared harness with wires, because its length may not be enough to combine all the nodes.

Now, with regard to the control panel. When installing a "commander" in the car, you must immediately determine free space on the dashboardwhere it will be possible to derive control elements (perhaps even, you will have to disassemble some part of it). The boilers for heating fluid are installed only on a reliable base, with a circle of them there should also be enough space, because all the wires must be placed in a free order and as far as possible from moving mechanisms.

Well, when preparatory stage Passed, consider the entire installation procedure in step by step mode:

1. The main part of the electrical preheater is fixed to the place selected in advance;

2. Then it is worth checking the quality of the installation fastening, if necessary, you can use special brackets;

3. Next, the installation of the fuel plate is made (or enters the purchased kit, or is purchased separately). Installation sites - Points of connecting filters and fuel hoses, and a procedure is performed using a tee;

4. After that, connect electrical system Heater: The device is powered by the device, and turning on / off control is displayed in the cabin;

5. Now the device can be connected to the cooling system (notice: after the procedure is performed, it will have to top 1 liter of fluid to the system);

6. We visually check all the connections of the system, they must be durable and reliable;

7. The last step is to check the preheater operation: run the engine and observe the result.

The most difficult part of the entire process of self-installation, there is work with electricity, but even if you have to seek help to the electrician, the installation of the heater will still be cheaper than the service center service. Another, not less an important point Installations, is an exhaust from the device system. Since the poppy flow of air has high temperature, It is necessary to avoid the possibility of its hoses and hoses placed under the hood. The optimal solution for the solution of this problem is the direction of exhaust to the engine crankcase, which will also lead to an additional oil warming.

Now imagine the following: You have fulfilled all instructions of the instructions that came with the instructions, all as needed to be connected, and the electrical heater does not work, what to do? Naturally, with an independent installation of the device, the warranty is lost on it, which means that problems will have to be dealt with on their own or contact specialists, but not for free advice.

In any case, it would be more correct to check the performance of the preheater before installation on the vehicle, suddenly he is already in a non-working condition, but ... if he knew where you fall, the mattress would be forced. However, there are cases when everything worked before the installation, and after it the activities stopped. There are several main reasons for this phenomenon: Most likely, during installation, the connection of the device to the car's power grid was confused or the heater itself is damaged; It is also possible that the system simply does not receive fuel and it is necessary to connect to another way.

If independent attempts to eliminate these reasons were not crowned with success, you will have to seek help from specialists. There you can get more solid answers to all your questions and quickly eliminate the problem.

Some car owners connect the heater to, but for this you have to overpass contacts in its block, which requires special skills in electrical engineering. Therefore, if such a thought comes to your mind - think twice, whether it is worth doing it. In general, we described only the general moments on the installation of an electrical preheater, and all the subtleties and nuances of this process, you can find out with the instructions or with a specific manual for installing a particular device brand.

The most inexpensive view of the engine preheater is the electric, built into the cylinder block, or posted next to it. In essence, this is a modified electricity. Only its main task is not to bring fluid to boil, but in heating to such a state so that the motor can quickly start in the cold season.

With the first type, everything is clear: the power of the devices is only 400-750 W. Their purpose is to maintain a certain temperature mode directly in the cylinder block. In addition to the heating element and wire, leading to a 220 volt outlet, no additional sensorsNo pipes and other devices here are not available.

Video - independent installation 220 volt engine engine heater:

Do you have a little "boiled" with wire? Then it will not be superfluous to buy an ordinary timer, if you so fundamentally important accuracy up to every second.

The most famous Russian heaters of this type are "Strong" (from 1,200 rubles), "Start Mini" (from 950 rubles). Mentioned devices are mainly designed for, but are there any obstacles for domestic craftsmen?

In fairness it should be noted that our motorists still consider the car primarily the luxury to which too much money is spent. People are somehow not ready to "indulge" their iron horses by expensive heaters, and therefore growing and popularity of models, the cost of which does not exceed 2,000 rubles. The same cohort includes models with the names of "Leafter", "Start M1", "Start M2", "Sibir-M", "Alliance".

Recently, the aggregates of this type began to be improved, equipped not only by the timers, but also the emergency switch, which, in case of overheating, stops the flow of electricity. The disadvantage of such designs is that they have become harder to install in the space near the engine.

Another point that makes it too pleasant to use such devices - the need to open the hood cover every time to stretch the wire from the device to the outlet. True, now the connector has already become applied under the bumper, which greatly facilitated operation.

Video - 12 volt engine preheater (24V, 220V) in the form of flexible heating plates:

More "advanced" preheating heaters are autonomous, adapted to the power supply from the vehicle network and designed for voltage at 12 volts. Along with the mass of advantages, such devices have very significant drawbacks:

• the presence of internal devices subject to wear and requiring replacement;
• the formation of plaque in bodies and combustion chambers due to insufficient fuel purification;
• installation requiring certain skills;
• big value.

This is just the last point - the main reason for which the acquisition of pre-autonomous heaters is constantly postponed to "then". After all, not everyone can easily post on average from 30,000 to 90,000 rubles per device, even if its usefulness is no doubt.

Those who installed on their car leave a different one, but there are quite a lot of positive among them.

The electrical engine preheater is a mechanism that allows you to warm up the car engine without launch.

Such a need arises in cold weather. The operation of the heater simplifies the subsequent launch. Sometimes this device is used to heat the cabin.

The principle of operation of the electrical preheater

In contrast to autonomous heaters, electric work directly from the 220 V network (from outlets in parkingons, in parking lots).

The heating element warms the coolant. The temperature distribution occurs when the warmed liquid rises upwards.

The device is automatically shut off when the specified temperature is reached, i.e. It can be left included in the parking lot overnight without hazard overheating.

Main characteristics

Popular models

The selection of the stamp of the heater is determined by its functional, economy, the presence of a suitable model depending on the brand of the machine. As well as price and positive reviews consumers.

Defa (Norway). The advantages of the model are simplicity of installation, the optimal ratio of performance, power consumption and price.

"Severst": ease of installation, variety of models for different enginesTested for years quality, low price.

Advantages and disadvantages of electrical preheater

• The ability to save fuel (compared to autonomous heaters powered by the fuel tank).
• Fire safety.
• Easy to use.
• Compactness, ease. Unlike autonomous heaters, which weigh up to ten kilograms and more, the most bulky models of electrical heaters are about one kilogram. Small dimensions simplify the installation.

Note!

The main deficiencies, compared with autonomous heaters, two: this is the need for the availability of a free outlet and electricity costs.

Installation of an electric preheater

For liquid system Cooling The heating element is put on the cylinder block.

1. From the cooling system, remove the plug.

2. On the nozzles of the heater to wear hoses.

3. Dry liquid.

4. Put the heater, fix.

Attention!

The heating element should be located at the bottom of the cooling system. Electric heater Engine with pump can be installed anywhere.

5. Connect the sleeves.

6. Pour fluid.

7. Install a power outlet on the machine housing.

8. Connect the cables heater, control unit, connector, and other blocks, if any.

9. Make sure the system tightness and sufficient wiring isolation.

10. Connect to the network, check the performance of the system.

Cost

The price of the heater Defa depends on the power (1.4-5 kilowatt), technical features Models and ranges from 3.5 to 10 thousand rubles.

"Severrs" - from 3.5 to 7.5 thousand, also depends on productivity and model.
