Prestarting electric heater of the engine. Antifreeze heaters, types of devices, installation. DIY engine preheater

In the northern regions, the problem of starting the engine in the cold is always relevant - frost thickens the oil, complicating the cranking and worsens the volatility of the fuel, and reduces the current output of the battery. Even the difference in the thermal expansion of individual parts plays a role: the piston with a floating fit of the finger bites it in the cold, and the lower head of the steel connecting rod is compressed more than a cast-iron crankshaft.

Therefore, having started the engine, it is necessary to warm it up so as not to risk breakdown when starting to move. Here the minus of diesel engines is revealed: when idling, they slowly heat up even in summer, while in winter it is impossible to warm up a diesel in morse. Running in the cold - there is a considerable risk of cranking the crankshaft liners, scuffing the camshaft beds.

The practice of preheating the engine is as old as the cars themselves - and now you can see how the engine is heated with a blowtorch. But this method is inconvenient and unsafe. So, both home-made and factory engine preheater systems appeared a long time ago and continue to remain relevant.

Operating principle

The idea of ​​an engine preheater is simple: since the engine is filled with antifreeze, then by heating the antifreeze from an external source, it will be possible to evenly heat the engine itself. The working clearances between the parts will return to normal, the oil will warm up (it will heat up in the sump from the heat of the crankcase and on many machines, after starting, it will start to pass through the oil-and-oil heat exchanger) and the intake manifold. For diesel engines and engines with distributed injection, this is less relevant, for a carburetor motor, heating the manifold and the carburetor itself in the area of ​​the system jets idle move is necessary. The motor will give part of the heat to the gearbox, which is also important. Once in the car, you can immediately defrost the glass.

Preheaters are divided into two categories

1. Electrical.
2. Autonomous.

The simplest prestarting electric heaters are heating elements in metal pipes, cut into the lower radiator pipe. Such designs are homemade due to their simplicity; in the northern regions of Russia you can see cars with a 220V plug sticking out from under the hood. In Northern Europe, you can even find parking lots where each parking space has a post with a socket.

The minus of this is also understandable - heating is slow due to the lack of forced movement of the liquid in the circuit. It is avoided by introducing an additional electric pump into the cooling circuit, but the need to connect the preheater to external source current remains. But electric heaters do not lose popularity, there are interesting models that warm up the engine and at the same time recharge the battery.

The liquid (autonomous) heater is connected to the electrical system, the fuel line and the cooling system.

But how to warm up the engine when the outlet is not nearby? There is only one option - to burn your own fuel. This is how autonomous pre-heaters are arranged: these are small stoves that burn fuel taken from the tank and heat the built-in heat exchanger. It is easy to automate such a pre-heater - connect a timer to it, a control output from an alarm. Thanks to this, on commercial vehicles, such models, for which you can even set a weekly heating schedule, are installed from the factory, and the name of the manufacturer of autonomous heaters Webasto repeated the fate of Xerox, becoming in colloquial language a synonym for pre-heating systems.

Of course, autonomous heaters have their disadvantages:

1. First, they need fuel - with an almost empty tank, you will be left with a cold car.
2. In the same way, a battery charge is also needed - with an old battery, the motor will warm up, but the starter will not turn it over.

Therefore, many heating systems integrated with on-board electronics are automatically blocked when the fuel level or the battery charge drops below a critical level.

The fantasy is not limited to this, but its other fruits are considered rather curiosities. For example, heat accumulators have been invented - these are thermoses in which a certain volume of coolant is stored. While the motor is running, the heat accumulator is included in the common circuit and is heated to working temperature, when the engine is turned off, it turns off, retaining heat in itself. Starting a cold engine, the driver again receives a dose of antifreeze that has retained heat. It is difficult to take such developments seriously because of the short "shelf life" of the heat supply and because of the size. But they manage to be sold - these are the Canadian Centaur systems and the Russian AutoTerm.

If we recall the unambiguously useless devices, then these are oil heaters inserted through the dipstick. Not to mention the ineffectiveness of heating the oil in the pan, and the power of such "heaters" is so scanty that they cannot heat the oil, uselessly draining the battery.

Installation

Installation diagram Binar-5

The simplest electric heaters are installed simply - we drain the antifreeze, cut out the section of the lower radiator pipe to the required length, insert the heater into the cut pipe, tighten the clamps and re-fill the antifreeze. It remains to stretch the wires so that the car is easy to "plug into the socket".

Why does the electric heater bump into the bottom pipe? This speeds up heating due to thermal convection - heating systems also work without forced circulation. When inserting into the upper pipe, antifreeze is heated in the radiator, and not in the motor - a closed thermostat will not allow liquid to flow into the block due to convection.

If you have not a cheap Russian heating element, but a more advanced device, then it crashes into the pipe that goes to the stove. Such devices are a monoblock that combines a pre-heater with a low-power pump, so they cannot be connected to the main cooling line, which has a large flow area. But warming up the engine with them faster, and at the same time, the salon stove heats up at the same time.

For a number of motors, electric heaters are produced with the expectation of installing instead of technological motor plugs - to install them, you will need locksmith skills, since you will first have to remove the necessary plug from the motor, and then install the heater in the hole of the block hermetically. It is better to entrust this to professionals, as well as the installation of an autonomous heater - here you will need to intervene in the fuel system of the engine, and to correctly place the exhaust of the heater.

The best models of electric pre-heaters

Defa

The Norwegian company is a leading manufacturer of heaters of this type. It produces electric heaters, which both cut into the unit and are installed in the cooling circuit. The main advantage of Defa systems is modularity: the heater is complemented by charger for the battery, an autonomous fan for the passenger compartment, an on-timer. If desired, choose a model of a heater with a thermostat - such a heater is left constantly on, without risking overheating the motor and saving energy, since when the set temperature is reached, the heater will automatically turn off.

Calix

Another Scandinavian firm. In its model range there are universal heaters cut into the nozzles, they are simple, reliable and efficient. Modular design is also used: the buyer can configure the desired system by himself, by purchasing additional control devices and battery chargers for a suitable heater. Owners diesel cars will appreciate the availability of easy-to-install electric tank heaters in the Calix range.

Severs

And these are the products of ZAO Leader. With all the advantages of European heaters, the disadvantage is the price, so offers Russian manufacturer will not be superfluous.

The model range includes simple convection heaters and "Severs +" models with forced circulation. The heater is supplemented with a timer and a battery charger.

Popular autonomous pre-heaters

The German concern with a century of history is known primarily for autonomous heaters. OEM models are available, installed on conveyors by the car factories themselves, and kits for self-assembly.

Each such set is created for a specific car and therefore stands up with a minimum of possible modifications. For control, own units are used, which are interfaced with the heater with a proprietary digital bus. It is used in conjunction with modern alarms - for example, StarLine systems were able to control Webasto in the last generation. Thus, the pre-heater is started by a timer and by a command from an alarm key fob and a mobile phone.

Eberspacher

The second German "titanium", the brand of which did not become a household name, perhaps because of the difficulty of pronunciation for the Russian language. Branded Hydronic heaters are universal units that are equipped with their own installation kit for a specific car model. Airtronic air heaters are produced separately for cabins - they are relevant for commercial vehicles, where the driver can spend the night in the cab in winter, while there is no point in spending fuel on constant heating of the engine all night long.

Teplostar

The Samara manufacturer will interest many: prices for Webasto or Eberspacher products were considerable even before the crisis, but now they have doubled. Teplostar's model range includes models of pre-heaters designed for different engine sizes, for different fuels and voltage of the on-board network. An interesting feature of the company is that the heaters are equipped with GSM modules: you can turn on the heater from your own phone, if you wish.

The climatic conditions of most of the territory of our country are distinguished by a very wide range of temperatures: from heat in summer to freezing frosts in winter. In the summer, car operation is quite simple, although it has its own specific features. And in the cold season, the car engine takes a long time after starting to reach its operating temperature. And to facilitate a cold start and save time when you warm up the car, there is an electric engine heater, which in a fairly short period of time is able to bring its temperature to acceptable values.

Features of starting the engine in the cold season

Engine internal combustion due to the peculiarities of its design, it is able to develop the maximum of its power and torque in a rather narrow temperature range... That is why cold start, especially in winter time years, so bad for engines. Previously, before the advent of pre-heaters, the only way was to start and warm up at idle or increased speed. Now, with the advent of various means and methods of heating, this method can be neglected. Moreover, modern motors very efficiently distribute heat from the combustion chambers and warm up quickly, so you can start driving almost immediately after starting. But this can be done in normal winter conditions, but if at night the temperature reaches 40-45 degrees below zero? Here, additional heating of the engine in winter is simply necessary.

What is an engine heater

In the general case, engine preheating is carried out by artificially raising the temperature of the coolant so that it heats up the engine parts (the block and the cylinder head, as well as the heater radiator). This makes it possible to significantly reduce the negative effect of increased frictional force during start-up and local (uneven) heating of its parts.

Types of engine heaters

Actually, there are only two types of heaters - autonomous and electric. Autonomous heating, as the name suggests, does not depend on external conditions and is part of the automotive power plant: it uses fuel from the tank for its operation. The most famous example is the Webasto autonomous engine heater. Special boilers use the combustion of fuel to heat the coolant that circulates through the system - and all this without starting the engine.

An electric auto-heater is also built into the engine cooling system and, using a special heating element, like a boiler, heats the coolant.

Electric heater as an alternative to stand-alone devices

The installation of a 220v engine heater is much easier (since it has, in fact, only one element and wires for connection) and much cheaper, while it does not use gasoline as a heat source, costing electricity.

Varieties of electric heaters

Blocky

The simplest type of heaters, which are installed in the cylinder block instead of a plug on the side. They are an electrical heating element in the housing and a connector. Such models do not have a large power consumption (500-700 W), however, due to the fact that they are located directly in the engine, they warm it up almost in the center. More sophisticated engine heating systems can be equipped with interior fan heaters, a start timer and a remote control. The only problem with installation can be the engine breather (crankcase ventilation hose), as it is often installed in such a way that it covers the plug in the block.

Branch pipes

Such devices are installed in the cut of the main pipes of the cooling system. The heater itself is equipped with a special adapter housing that is installed directly on the hoses. The disadvantage is that most of these devices are designed for standard hose diameters. For such devices, the power can be higher (up to 2-3 kW), the functionality and equipment are about the same as in the previous group.

Remote

This is a special group of devices that are also built into the cooling system, but are more complex in design and installation. Such models are more like Webasto heaters, only they run on electricity, not gasoline. Such models warm up the coolant and the cylinder block most efficiently. The external heater can also be provided with forced circulation of coolant, which better promotes uniform heating of the cylinder block and minimizes the harmful effects of cold starts. The cost of such units differs by more than an order of magnitude (from 1.5 thousand rubles for conventional chinese models up to 23 thousand rubles for a really good American HotStart). The power of the heating element also varies greatly and depends on the displacement.

Advantages of heating a 220v engine:

• Low cost the installation kit and the installation itself (from 1 thousand rubles).
• Wide the lineup , compatibility with almost all motors, simple design and high efficiency.

Disadvantages of an electric heater:

• In the nearest availability there should be a 220v household outlet.
• Open hood during heating operation... On the modern models this is not so important, since they are equipped with a special connector cut into the front bumper.
• Reliability of some models, which over time begin to pass coolant at the junction with the engine.

How to put an engine heater

Do-it-yourself engine heating installation is a relatively simple task. It does not require a special tool and special knowledge. You just need a general understanding of the principles of operation of car engines and an idea of ​​the location of components and assemblies under the hood.

To understand how to install the engine heater, just look at the installation instructions that came with the kit. The general installation sequence is as follows.

1. Since the heater is installed in the cooling system, it is necessary to drain part of the antifreeze (at least 2 liters in order to lower its level and prevent leakage during depressurization)
2. If a block heater is installed, the plug is removed from the cylinder block and a heating element is installed. For the remote or branch pipe version, the hoses leading to the heater radiator are removed. It is better to use the hoses included in the installation kit so as not to cut the factory ones. When installing new nozzles, all connections are fixed with clamps, and it is advisable to coat the fittings with a sealant to avoid leaks.
3. The device body is attached with a bracket included in the kit.
4. All necessary connections are made, the rest of the assembly is carried out in the reverse order.
5. Antifreeze is poured back to the desired level... When filling, it is advisable to avoid the appearance air congestion(pour antifreeze into expansion tank carefully, in a thin stream!).

Installing engine heating is a task that is quite feasible for almost everyone. And which type to choose depends on the specific operating conditions and design features car.

An independent heater installed on the internal combustion engine reduces the warm-up time to several minutes. Many car owners will be skeptical about this prospect. In practice, however, installing a heater is much easier and more efficient than waiting 10-15 minutes in a cold car.

Installing a heater for a 220V engine does not affect the engine itself, but antifreeze, significantly increasing its temperature. This is due to a tungsten coil and a special block.

Preheater 220V engine, connected to the engine, does not work constantly, but only until the engine reaches its operating temperature. Then, with the help of the sensor, it is turned off, and the motor continues to work as usual.

Owners of a diesel engine will appreciate the installation of engine heating from 220V, since it is much more difficult for this type of engine to work with low temperatures... But it can be just as convenient to put heating on a gasoline car as it is on a diesel engine.

Another significant advantage, for the sake of which it is worth connecting the heater, is the economy of gasoline and diesel fuel, as well as quick heating of the entire cabin, which is very important for owners of leather seats.

Known types of devices

It is quite possible to make an engine preheater with your own hands if you have some skills and abilities. But first you need to figure out what they are in mass production.

There are two types of fuel heater:

• autonomous;
• electric.

The installation of an electric heater is considered to be simpler. It is inexpensive and easy to install. It is based on a special block that heats up the unit. A properly connected engine heating from 220 V. The set with it often contains:

• battery;
• remote control system;
• thermal sensor and timer.

The installation diagram of an electric engine heater is very simple, so every car owner can use it. The main disadvantage can be considered only the amount of energy consumed, which is high enough for such a device.

It is much more difficult to install an autonomous preheating of the engine, made by hand. Its system is more complex, the cost is higher. They are switched on with a button and do not require a mains supply. Installed autonomous heating operates from fuel system or from a special petrol tank.

The principle of operation is based on the principle of air recirculation, which allows you to start the engine and quickly start moving, regardless of weather conditions and the power supply network. The device heats up the antifreeze, which then rises, enters the radiator, cools again and returns to the heater.

So the liquid circulates until the whole system heats up, and it reaches the operating temperature. Autonomous heating connected to the cooling system can be installed anywhere that is free under the hood of the car. It also quickly heats the passenger compartment.

Installation and installation of the device

The prospect of not waiting for extra minutes on a frosty morning until the engine warms up seems very tempting for motorists. Many motorists at this stage will wonder if there is homemade heating... And how to install engine heating on your own?

To understand how to make an engine preheater, first you have to accept that it will work on electricity. Consequently, the presence of an outlet in the parking lot will be one of the operating conditions.

So, a self-assembled 220V engine heater will consist of a heating element, fittings and several fittings. The heating element must be connected to a small circle of the cooling system and equipped with a pump so that when the engine is turned off, the liquid can circulate.

Installation of an engine preheater has a fairly simple instruction, and for greater convenience, there are videos on the Internet that explain step by step the course of action.

The first thing that is required to assemble and install the heater is a tee for an inch pipe of a standard sample. It can be purchased at any plumbing store, and there you can also buy a heating element, which is also required to assemble your unit. The best option would be a heating element with an already built-in 1.5 kW thermostat.

Teng is installed at the end of the tee, and a ten-centimeter pipe is mounted at the other end. It is necessary for faster heating of the system. Plugs are installed on the free outlet and end of the pipe for further connection of the hoses.

Now we connect the resulting part to the coolant circulation system in the car. To do this, you need to find the place where the hose breaks from the bottom, where the exit to the stove is carried out, and build in a home-made device. A wire of a suitable cross-section is connected to the contacts of the heating element, and at this the first stage can be considered successfully completed.

This is followed by the connection of the pump, with the help of which the liquid will circulate. The easiest way will be to use a pump from a Gazelle, since it is universal and has a fairly affordable cost. It is connected in front of the heater using an open relay to a car network or a regular outlet.

These are the main points for which the engine heating is installed.

Danger of untested systems

If you have absolutely no skills to do this kind of work, the best option will be the acquisition of a ready-made device. In this case, how to connect the heating will be told by the instructions that come with the unit.

If you independently intervene in the internal combustion engine system and its cooling cycle, there is a risk of damage to some elements if you know about the internal structure of the car by hearsay.

If the desire to figure it out and do all the work on your own is too great, then you should enlist help. Usually experienced motorist can understand the part of the system where the heating is installed and will tell you the location of the necessary parts.

The easiest to use, but at the same time the most functional device is considered to be a device for diesel engines of the PZhD. It costs modestly, but works efficiently. Supports manual and automatic start, works with antifreeze and antifreeze, in medium power mode it consumes less than a liter of fuel per hour of operation.

PZhD is able to withstand temperatures up to -45 degrees. You can install it yourself using the instructions or by contacting the nearest car service, where this work will be done in a few minutes.

Remember that any intervention in the internal structure of the car must be qualified.

Before wondering how to install a pre-heater for the engine in the winter season, consult a professional. An experienced specialist will help you determine which model is best suited for your car, model, year of manufacture and mileage, or it is not necessary to put heating at all.

Each car is unique. And it's not a fact that a heater, which is great for a neighbor's car, will just as well reduce the warm-up time of another's engine vehicle... You should always rely only on the authoritative opinion of a specialist.

The pre-heater is a device that is indispensable for most drivers in the cold season. Thanks to a simple but effective device, starting the engine at subzero temperatures will take place in a matter of minutes. But at the same time, you do not have to warm it up for a long time. idle.

Many will probably think that this is impossible. After all, warming up the engine in the cold season is simply necessary, and for this you need to start the unit and stand for some time with the engine running. Only after that you can get under way, and then without accelerating to high speed.

This process usually requires a significant investment of time and gasoline. And the lower the ambient temperature, the longer it will take to warm up the motor. Of course, this factor does not have a very favorable effect on the state of the environment. A sensible alternative is to install a pre-heater for the motor. Next, we will tell you how it works. this mechanism and how it can be installed on your car. And at the same time - about the features of the operation of the prestart mechanism. We will also provide a video on installing a 220V preheater on a car.

What is an engine preheater

Before installing the mechanism on your car, you should understand the principle of its operation. The fact is that the heater does not heat the unit itself, but the antifreeze liquid. It is arranged as follows: a tungsten coil is placed in a special block.

It is located under the engine, works temporarily until the mechanism warms up and the car starts to work as usual. That is, the device performs the same function as a long warm-up of the engine, only this does not consume fuel. It is enough just to turn it on for a while, then start the car and start moving.

Regardless of whether the car engine is powered by gasoline or diesel, the device will be equally effective for both types of engines. The preheater is especially relevant for diesel units, which are much more difficult to start at low temperatures than gasoline ones.

What are engine pre-heaters

For now, let's drop the option homemade device, since most experts are inclined to think that experiments in this area are acceptable only with certain skills and knowledge. Otherwise, they will be dangerous.

As for the heaters from the manufacturer, they are divided into two main types:

• electric pre-heaters 220 V, the installation of which we will consider in more detail below. One of the advantages is low cost and simplicity, therefore almost everyone can install such a device on their car;
• autonomous pre-heaters that do not require an electrical connection to operate. Such mechanisms are very convenient. In order to activate them, you just need to press a button. Power comes from the fuel system or from gasoline in a special fuel tank... But their cost is much higher than those devices that are powered from the mains.

Autonomous pre-heaters

Standalone devices They are mounted so that the car can be started at any time of the year, at any temperature, and regardless of whether there is a 220 V socket nearby. They are simple in design and are based on the principle of air recirculation.

In general, the heater works in much the same way as its analogue, which operates from 220 V. The coolant is heated directly in the device block. Heated antifreeze rises up the system when it leaves the block. In the radiator, it cools down again, and through natural circulation it flows back into the heater. So the liquid circulates until it completely heats the unit.

Depending on the characteristics of the device, it can be mounted in two ways:

• connection to the car's electrical systems;
• connection to the cooling system.

In addition to the standard functions, the heaters quickly heat up the car interior. You can install them in any free space under the hood of the car.

Electric pre-heaters 220 V

As mentioned earlier, an electric heater has a fairly simple design. All the main work is performed by a unit with a small element designed to heat the coolant. In this case, it will, on the contrary, heat up the unit. In addition, the preheater has a power cable that connects to a 220V outlet. It is this version of the preheater that most often craftsmen make by hand.

Depending on the configuration, the heater can be equipped with the following options:

• device for recharging the device's battery;
• timer with thermostat;
• fan;
• remote control.

The price of a pre-heater is usually low and mainly depends on the availability of certain options. The installation diagram of the electric pre-heater is quite simple. Installation does not require certain skills, therefore, for installation, you can do without visiting a service center.

Important! A pre-heater, operating from a 220 V network, consumes quite a lot of electricity, since the heating element installed inside the device has enough high power... Its indicator may fluctuate depending on the characteristics of the product.

How to install a 220 V pre-heater with your own hands

Do-it-yourself installation of the heater does not require much time and any special knowledge. Almost every car enthusiast who knows where the main working components of the car are located will be able to cope with the task. The installation process itself will take no more than 3 hours. Video instructions for installing the prestart mechanism will help in performing all the necessary work:

But if you are not sure that the installation will be performed normally, it is better, after all, to visit the technical station.

When self installation should adhere to detailed instructions... As a rule, it comes with the device.

The sequence of actions when installing a pre-heater for 220V.

Heater operation

Often, the manufacturer promises that it will take no more than half an hour to fully warm up the unit. But at low temperatures, this figure can be from one to two hours.

The pre-heater, directly connected to the car's stove, quickly warms up not only the unit and adjacent systems, but also the air in the car's interior. Thus, the engine preheater performs two functions simultaneously. The engine does not need heating if the ambient temperature is +10 degrees and above. In this case, there is no need for unnecessary energy consumption.

Preheat the engine in winter period can be simple and easy if you install a heater. If you are not yet aware of such a possibility, let's look at this information in more depth. Such heating can be carried out using electric heaters that operate both from the vehicle's mains and from a socket.

To begin with, the electric heating of the 220 V engine is carried out with the installation of a preheating system. I want to note that such devices work by connecting to a household network.

The engine coolant increases its temperature due to the fact that it is heated by a thermocouple. The circulation of the heat carrier begins through the system of a small circle of cooling. As soon as the required temperature is reached, the thermostat is connected to work in order to disconnect the heater from the network.

Thus, heating the engine electrically prevents the cooling fluid from overheating. The temperature system is automatically regulated, so such a device can be left overnight without worrying about possible overheating. In general, everything is very simple. However, let's take a closer look at what such a system consists of in order to understand the general essence of the work.

On sale you can find several types for heating the engine using 220 volts. Which boilers to choose ?!

DEFA WarmUp heating system

This Norwegian device, although simple, is very reliable.

Heating elements are designed for many engine models and are installed in the engine plugs.

The operating process is simple: a "boiler" - heats up the coolant, and together with it, the oil is heated. This device can work even without a control module.

Those who prefer comfort can use complete set Defa heating and set:

• a heating module in the cabin, which is fast;
• a battery charger that will ensure that the battery is fully charged throughout the winter;
• module for managing the entire system;
• SmartStart control panel, works from a distance of up to 1200 meters;
• special cable for 220V network.

The price of a 220v engine heating system from Defa depends on the configuration and brand of the vehicle.

Video: preheaters Defa.

There are similar analogs and domestic production, but - the quality is lame!

Other electric heaters

On the market you can buy boilers for heating the motor of other famous brands, For example:

• Start-M;
• Severs-M.

How similar electric boilers work:

when the device is connected to a 220V outlet, the coolant is heated in its body and with the help of a valve, due to the pressure difference, directed circulation (antifreeze) through the heating and cooling system of the vehicle is obtained.

And the thermostat is designed to prevent overheating of the device itself and the cooling liquid.

How to install heating with your own hands

In the purchased kit there is an installation manual that will help you install the pre-start electric boiler yourself.

All instructions are different depending on the model of the device, but the installation principle is usually as follows:

1. drain the coolant;
2. fix the electrical appliance to the cylinder block;
3. instead of the temperature sensor, put a tee fitting and screw the temperature sensor into it, and put a branch for the hose through which the heated liquid will flow;
4. instead of drain plug(tap) on the cylinder block, put a branch for the hose for the cold liquid, which will go into heating;
5. tighten the hose clamps;
6. pour (antifreeze).

Methods for heating a diesel engine in winter and which type of heater to choose?

Today already has good equipment for heating diesel engine in winter. Mainly produced are types of electric heaters powered by the vehicle network for heating the diesel engine fuel system.

What types are:

• filter heaters fine cleaning, are installed inside the filter;
• flow heaters, mounted in the fuel line;
• bandage heaters, put on the filter housing;
• heaters of the posistor type, installed in the fuel intake in the fuel tank;
• well, autonomous engine heaters (liquid) are installed in any cars.

Video: heaters overview diesel fuel Nomakon.

When choosing a heater, I recommend paying attention to the engine design and parking conditions. Autonomous heaters need fuel in the tank and excellent condition battery... Storage heaters are beneficial for frequent use.

pay attention to electric heaters from the 220V network. The electric option is a win-win for the diesel engine. They are inexpensive. They are especially relevant in cases where the car is located in the garage or at home. You can purchase the Severs, Electrostart or Defa models in order to save your budget.

Efficiency of engine heating using the Webasto system

Those who are not constrained in funds can use the engine heating, as it allows you to get rid of a number of unpleasant moments in the winter. This system is produced by German manufacturers in two varieties.

In general, the device is a small combustion chamber. It is mounted in the engine compartment and connected to the cooling system. When antifreeze is heated, the engine heats up. Through the cooling system, the liquid moves through the radiator of the stove due to the operation of an autonomous pump.

Liquid preheater - device and principle of operation

Do not forget that such a system, among other things, helps to maintain the optimum air temperature in the cabin, no matter how many degrees it is outside. However, with such a system, fuel consumption becomes slightly higher.

However, if you try to compare the possibility of prolonged warming up of the engine in the absence of a heating system, then this consumption is compensated. At the same time, the driver gets maximum comfort and convenience, since he will have to forget about such a problem as a cold steering wheel and seats.
