Installation of engine warming. Engine preheating system

The desire to maintain the engine of the car in the optimal temperature regime is more than justified. In the winter, this is not only a kind of insurance against the fact that the car just will not start. A frozen power unit spends far more resources on activating its functions - accordingly, its heating minimizes unnecessary stress and creates more favorable operating conditions for the mechanisms. As experts note, even the simplest engine heating installation, produced in the cooling system through the frame, reduces fuel consumption and increases the service life of the parts.

What is the engine heater?

This is a small device that generates heat by heating it or directly the engine or adjacent mechanisms. There are liquid models and electric ones. If you need to heat the engine in winter from an autonomous source, then you should choose the first option. In such designs, a small combustion chamber is provided, which independently of external sources will fulfill its function. Electric heaters are advantageous for small dimensions, but they require connection to an automotive electrical network. Heating control is usually implemented using the remote control, which is located at the owner. The owner of the machine activates the heating function at any time, if necessary, or program the system to work on a specific schedule.

General principles of installation

The traditional installation scheme provides integration of the device into the cooling system. Accordingly, the question arises as to how to put the engine heating in this part of the technical stuffing of the car? This is done in two ways - either through an existing production hole, or by tapping the device. But even this is not the main difficulty of the process, but in finding the optimal location for heating. Specialists recommend choosing the lowest possible point in the pipeline contour, which will eliminate the risk of air blowing of the heater.

If there is no technological hole in the line, and there is also no desire to dismantle the existing pipeline, then if possible it makes sense to use an additional hose that is easier to connect to the cooling system. In any configuration, the engine preheating installation will assume its mechanical fixation to the housing. The search for anchor points depends on the particular model of the car, but in all cases it is not recommended to install it to the silencer collector, since this solution in practice can lead to the ignition of not only the heater itself but also the supply wiring together with the hoses.

The technique of sequential installation

In this model of the heater installation, the installation is realized through a line connecting the engine with the heating in the cabin through a cooling system. The main task of the executor is to find the input and output channels of the pipes, after which drain the liquid through them and connect the heating device to them. However, you can not activate its function immediately after installation. It will be necessary to wait again for the liquid to fill the capacity of the integrated component. Such an engine preheating installation has many advantages, which are ensured by the system's closed system and its reliability in terms of protection against fires. This option is simple, efficient, reliable, but at the same time it is recommended to perform it only with a high-quality heating device, since it will bear considerable responsibility during the operation of the engine.

Parallel installation technique

The previous version is implemented by a simple, but in some way rigid scheme with respect to the cooling system. At the same time, the collision of hot flows with a cold liquid does not add efficiency to the heating process. Therefore, many turn to an alternative scheme, which provides for not direct connection of the device to the cooling system, but parallel. What is the parallel installation of heating the engine? In this case, the coolant circulation circuit remains virtually intact, but a duplicate coolant circulation loop is connected to it, which will also interact with the cold flows, but in a softer mode. The main disadvantage of this method is the use of additional materials in the form of hoses and nozzles, which will in effect have to repeat part of the circulation line of the cooling system.

Features of the heating installation for the diesel engine

Such systems operate on the principle of heating diesel fuel by splitting paraffins, which are formed in conditions of low temperature. Before starting, the diesel engine can be heated from the battery, and after it, there is also the possibility of power supply from the generator.

In terms of installation, such heaters are divided into several types. Models of a bandage type, for example, are installed in a system of fine fuel filtration. Distributed and in-line flow devices that work with the fuel main. How to put the heating engine of this type? It can be embedded in the main line of the fuel system, after which the heating of the liquid passing through the formed shirt will be realized.

Installing the thermostat

In addition to the heater, it will not be superfluous to install a thermostat, which is usually included in the package of branded devices. It is desirable to install this component precisely in technological holes. Another thing is that integration itself can be carried out in different ways. For example, there are devices with a thread. This is not the best option, but if there is no way out, then it is necessary to screw the mechanism into the available hole due to the force. By the way, the engine preheating system can be built in according to the same scheme, depending on the design features of the model. Another option involves the installation of a thermostat with spacers. At first the antennae of the mechanism is inserted into the niche of the tube, and then by means of clamping or by means of twisting, the spacers diverge and thus fix the device.

How much does the engine warm up?

Sets with heating systems in the simplest versions can be purchased for 1-1,5 thousand rubles. As a rule, these are devices made in China that do not have high quality and reliability. The products of large manufacturers are estimated at a minimum of 2 thousand. These are also simple modifications, but they are already characterized by durability and constructive reasoning. In the higher segment, the engine is heated, the price of which is about 4,000-5,000. These are high-tech kits with an expanded equipment, which are also distinguished by modern controls through multifunction relays. Some manufacturers propose to car owners to form a single heating infrastructure for different parts of the machine, the control of which will be provided by the same relay and control panel.

Conclusion

The need for a system for heating the engine power unit in cold regions has always existed. But this problem was solved in many ways. As the professionals note, heating the engine in winter with a pre-start device is by far the most practical and effective method. Of course, it requires costs and, as a rule, not the most pleasant editing procedures, but the end result justifies itself. In practice, the car owner will only have to manage the heating process with a few buttons.
