Inside the tank 1 (Figs. 1-3), below the coolant level of the engine cooling jacket 2 (Fig. 1), an electric heater 5 (Figs. 1-3) of a large capacity of 3.5 kW is installed, allowing to quickly heat the engine block, sequentially connected by an electric cable 6 (Figs. 1-3) to a temperature relay 7 (Figs. 1-3) and an electric cable 6 (Figs. 1-3) connected to an external source of electricity 8 (Figs. 1-3) by voltage U-220b . (volt). Capacity 3 (Figs. 1-3) is made of two detachable parts, the lower part 9 (Figs. 1,2) and the upper part 10 (Figs. 1-3), interconnected by protrusions 11 (Figs. 1-3) through a rubber gasket 12 (Fig.1,2), made on the upper end surface of the lower part 9 (Fig 1,2) of the tank 3 (Fig 1-3) and the lower end surface of the upper part 10 (Fig.1-3) of the tank 3 (Figs. 1-3) and through holes (not shown in the drawing) in the protrusions 11 (Figs. 1-3) by rigidly connected bolts 13 (Figs. 1-3) and nuts (not shown in the drawing), forming a closed container 3 (Figs. 1-3). The lower part 9 (Fig. 1,2) of the tank 3 (Figs. 1-3) is equipped with a pipe 14 (Figs. 1-3) mounted on the inlet pipe 1 (Fig. 1), and the upper part 10 (Figs. 1- 3) capacity 3 (Fig.1-3) is equipped with a pipe 15 (Fig.1-3) mounted on the outlet pipe 4 (Fig.1). On the lower pipe 14 (Figs. 1-3) of the inlet pipe 1 (Fig. 1), a rubber valve 17 (Fig. 2) is freely fixed on the axis 16 (Fig. 2), which under its weight closes the hole 18 (Fig. 2) incoming lower pipe 15 (Fig.1,3) of the lower part 9 (Fig 1,2) of the tank 3 (Fig 1-3). The electric heater 5 (FIGS. 1-3) of the device for maintaining the internal combustion engine 2 (FIG. 1) in a heated state is located in the hole 19 (FIG. 2) made in the lower part 9 (FIG. 2) in the tank 3 (FIG. 1-3) and comprises a thermal electric heater 20 (FIG. 2), a device for attaching a thermal electric heater, comprising a housing, a threaded fastener 21 (FIG. 2), with a thermal heating element 22 (FIG. 2) mounted inside the thermal electric heater 20 (figure 2), fixed by the outer surface in the hole 19 (figure 2), made m in the wall of the tank 3 (Figures 1-3). Thermal heating element 22 (Fig. 2) is made in the form of a plate having a wide part located inside the tank 3 (Figs. 1-3) and a narrow part located both inside the tank 3 (Figs. 1-3) and outside it . A rubber sealing ring 23 (FIG. 2) is located on the threaded fastener 21 (FIG. 2), located on the inside of the container 3 (FIGS. 1-3) in front of the hole 19 (FIG. 2), and a nut 24 is screwed onto the thread ( 1-3), closely adjacent to the hole 19 (figure 2) on the outside of the tank 3 (figure 1-3).

The power of the electric heater 5 (Figs. 1-3) up to 3.5 kW and I-220 V, which corresponds to the technical requirements for the use of sockets 8 (Figs. 1-3) installed in apartments.

The operation of the device to maintain the internal combustion engine in a heated state.

With the internal combustion engine turned off, to warm the cylinder block through the cooling jacket of the internal combustion engine 2, we turn on the liquid heating system in the tank 3 from the external electric power source 8 using the electric heater 5 installed in it. For this, turn on the external electric power source 8 to 220 V.

The temperature relay 7 gives an impulse to turn on the electric heater 5 in the tank 3, which, through the inlet pipe 1, the lower pipe 14, the rubber valve 17 on the axis 16, are connected, on the one hand, to the tank 3, and on the other hand to the cooling jacket of the engine 2. Capacity 3 through the upper pipe 15 is connected through the outlet pipe 4 to the cylinder head through the cooling jacket of the internal combustion engine 2. The current from the external electric power source 8 is supplied through the electric cable 6, through the temperature relay 7, fixed e springs in a semicircle (not shown) to the body of the tank 3, enters the electric heater 5, which begins to heat the liquid in the tank 3, designed to cool the internal combustion engine 2. In this case, the hot liquid inside the tank 3, expanding in volume rushes up, pushing the entire volume through the upper pipe 4 into the cooling jacket of the engine 2, mixes with cold liquid in the cooling jacket of the engine 2, heating it, and through the lower pipe 1, through the lower pipe 14, the heated liquid and From the cooling jacket of the engine 2, pushing the rubber valve 17, enters the lower part 9 of the tank 3. Thus, the heated fluid circulates in a closed circuit. When the temperature in the tank 3 t-95 degrees turns off the temperature relay 7 electric heater 5. When the temperature in the tank drops to +70 degrees C, the temperature relay 7 is activated, the circuit is turned on, that is, the temperature in the tank is maintained until the external power source 8 is turned off.

The device allows you to quickly warm up the block of the internal combustion engine 2, for example, a VAZ car at a temperature of -20 degrees, the cold internal combustion engine 2 before starting is warmed up from the hot liquid in the tank 2 for 15 minutes to a temperature of +50 degrees C.

The device allows you to connect to 220 volt sockets installed in apartments and maintain a temperature in the engine cooling jacket for 2 + 70 degrees C for a long time, for example, on KAMAZ vehicles. In the parking lot, the driver rests all night in warmth and silence.
