Engine preheater - electric, autonomous

Engine preheater - a device that allows you to warm up the engine to the optimum temperature before starting it. In addition, this device allows you to warm up the air in the cabin, thereby fully preparing the car for a trip in the winter without wasting time on warming up and cleaning the car from snow and ice.

Electric pre-heater

The electric heater is not self-contained. For its operation, it is necessary to have a 220V power supply nearby, which you will agree is not so convenient, since in Russia there are practically no parking lots and parking lots with accessible sockets. However, some manufacturers already include this option in the standard package of their vehicles. Mostly this system is installed on cars in the northern states of the USA, Canada, etc.

The problem of the presence of sockets in parking lots and parking lots

The principle of operation of an electric heater is that the system is connected to an alternating current (220V). With the help of an electric heating element, the coolant is heated, and the circulation is carried out due to the fact that the already heated liquid rises up, and the cold one remains at the bottom, therefore it is necessary to place the heating element as low as possible in the entire system. If a pump is installed, then the heating element can be installed anywhere.

In addition, the system provides a special coolant temperature sensor and when the temperature becomes optimal, heating is stopped, thereby preventing overheating and unnecessary power consumption.

Autonomous pre-heater

The autonomous heater can run on petrol, diesel fuel and gas. The principle of its operation is as follows. The heating system uses a gasoline pump to pump gasoline from the car's gas tank into the combustion chamber, where it mixes with air and is ignited by a spark from a spark plug. Through the heat exchanger, heat is transferred to the coolant, and the pump of the heating system forces the fluid to circulate through the jacket of the cylinder block, as well as the stove (channels of the interior heater). After reaching the optimum temperature, the stove fan turns on and supplies warm air to the passenger compartment, which melts the ice on the windows and creates a comfortable temperature.

The disadvantages of this type of heaters can be attributed to the fact that they use the fuel of your car, the battery (with a poorly charged battery, it can be planted completely). And also the cost of a liquid heater is quite high.
