The low temperature start motor becomes difficult, which leads to its significant wear. Installation Engine preheater not only makes it possible to solve this problem, but also ensures the engine start in all conditions. In the first place, preheater need on diesel power units that do not rarely denied in the winter due to increased viscosity of the fuel. Additional convenience Autonomous heater is the ability to create a comfortable microclimate in the cabin due to its warm-up. About this further in the article.

Autonomous engine heater

Independent pre-start engine heater can be installed in the vehicle power supply system or cooling system. Such a heater is easily mounted both on petrol, diesel and the types of motors. It consists of a medium-sized chambers with an air-fuel mixture and special kapilnogo pin, igniting the mixture. The walls of this chamber is kept circulating coolant. It is heated and by means of the pump enters the small loop of the cooling system, which ensures the heating of the power unit, as well as heating the passenger compartment and defrosting glasses.

Since the construction of the heater is not built into the vehicle itself, you can install it in any place that you will find the most convenient. It should be noted that the source of energy to operate the auxiliary heater is the vehicle's fuel tank. Products can be equipped with remote controls or timers. Some models are controlled by a mobile phone.

diesel engine heater

Separately want to consider heaters for diesel engines. Because diesel is much worse suffers drop in temperature than gasoline. Therefore, in conditions of negative temperatures drastically deteriorate the quality of the power unit at startup and operation. The problem is that the operation of the diesel engine is that the fuel-air mixture comes under the influence of heat which is formed during compression. If the window are zero temperature and engine pistons, new enough, with the launch of the problem does not arise. However, the lower the outdoor temperature, the harder it is to run a diesel engine, especially if it is poorly put, is not new.

To solve this problem the designers of diesel powertrains have to go to various tricks - to use an undivided chamber, adding to gasoline lubrication system, to set up special impaling candles and other. Therefore preheater diesel engine makes it possible to simultaneously solve many problems that are associated with the launch of the motor in the cold.

heater webasto

Vebasto is a small digital device that performs pre-start heating of the engine. Initially, it was used in the transport of German manufacture. Its main function, oddly enough, was to create a comfortable environment inside the vehicle. The portable device is installed in any available place of the vehicle engine compartment. After installation, it does not require follow-up care. Included with the heater includes a remote control, which allows you to run the motor at a great distance (the distance depends on the model purchased, as well as its configuration).

installation webasto

Heater manufacturers offer special instruction, the violation of which entails damage to structures. Installation webasto (diesel variant) for vehicles intended for the transport of dangerous goods carried out by experts.

• All vehicle components are located directly near the preheater webasto, must be protected from the negative effects - overheating, fuel falling, oil.
  
• It is very important to avoid a fire in case of overheating of the heater webasto, what follows:
  1. Use hard-flammables.
  2. Apply heat shields.
  3. Watch the full ventilation.
  4. Set webasto at a considerable distance from the vehicle elements.
  
• Do not install the heater where there are people (in the cockpit, the cabin). Only in emergency situations not install these components in a completely sealed enclosure.
  
• If webasto positioned in the engine compartment, can provide significant shielding. When operating the heater webasto may experience radio interference that may require additional screening.
  
• For fixing the heater you need at least three screws. The exhaust pipe must be routed so that exhaust gases are not able to penetrate the interior. Its end is directed downward or to the side, when the automobile exhaust at the bottom, a tube is brought to the rear boundary or to a vehicle driver's cab.
  
• The control unit and the electric wiring are arranged so as not to violate its integrity during operation.
  
• The fuel is carried to be protected from mechanical damage. It should be protected from significant exposure to heat all the heater elements.
  
• It is important to seal the fuel wires guarantee the absence of fuel leakage. When the leakage is necessary that fuel vapors do not accumulate on the electrical heater elements.

heater device webasto

The combustion air (1), the blower (2), outlet fluid conduit (3), a flame sensor / pin nakalyvaniya (4), an evaporator pad (5) and plugs (6), a control unit with temperature sensors (7), a heat exchanger ( 10), a combustion chamber (11), exhaust outlet (12), fuel intake (13), a circulation pump (14), a fluid intake pipe (15), a fuel metering pump (16).

webasto working principle

After switching on the heater starts to operate the blower. It blows the combustion chamber and exhaust system. At the same time, the control unit performs testing of all electric elements and sensors. Further, in the absence of errors, the fuel from the tank is in the combustion chamber by a fuel pump, which is ignited by a glow pin. After combustion of the air-fuel mixture by the exhaust gases leave the system with a flame arrester. Circulating pump with chase coolant through the heat exchanger preheater, warming it. The optimal time for the operation cycle of the heater - 40 minutes (at -20 degrees).

Preheater binary

Binary - it's pre-start engine heater designed specifically for light-duty vehicles and designed to:

1. Heating saloon car and the windshield on motor off.
2. Safe startup and warming of the power unit at low temperatures.
3. Additional warming of automobile interior and the engine switched on the motor during severe frosts.

This heater operates independently of the power unit. It is connected to the fuel system and the vehicle battery. The principle of this device consists in heating the liquid in the cooling system that forcibly pumped through the heater heat exchange system. The duration of action of the device of a full cycle is 45 minutes.

Useful advice

Preheater - irreplaceable thing in the winter. Indeed, in conditions of severe frosts, run the power unit is very difficult. The modern market offers a huge range of these devices to suit all tastes and budgets, so with a choice of heater plugs problems should arise.
