The present invention relates to the field of power engineering and is intended as an auxiliary power plant vehicles to maintain their internal combustion engines in hot condition, heating the air in the cabins and supply side of the electricity network.

Known liquid Autonomous heater, produced mainly by firms Webasto and Eberspacher containing fuel pump with fuel, the boiler comprising a combustion chamber with heat exchanger, water pump, thermostat, control system.

The disadvantages of liquid Autonomous heater should include significant energy consumption from the on-Board network of the vehicle, resulting in long work lead to battery discharge. In some cases, the battery discharge is so great that it is impossible to run an internal combustion engine of the vehicle.

Known heat setting (selected for the prototype), containing an internal combustion engine, an electric generator, a heat exchanger of heat of exhaust gas mixing device with a heater, a liquid pump with electric drive, check valve, valves, hydroline [Putin the Russian Federation No. 2421626, IPC F02G 5/02].

Specified heat and power installation in the structure has a complex branched hydraulic network with two valves for control of flow of cooling fluid, and a mixing device with electric heaters. All of the above design features lead to the following disadvantages:

1) the average size of a thermal power installation due to larger heat exchanger of the heat of exhaust gases, which works with a partial flow of the coolant;

2) the complexity of the control flow of coolant, which requires the presence of two valves

3) the movement of coolant through all of the elements of heat and power installation during operation of the internal combustion engine of the vehicle.

From the foregoing it follows that the known heating systems of internal combustion engines of vehicles have several disadvantages that reduce their effectiveness and usability.

The objective of this invention is to provide a liquid heater of the internal combustion engine of a vehicle having a simple structure, higher thermal efficiency, small size and electronegativity from the battery of the vehicle.

Liquid podagra the motor vehicle includes an internal combustion engine, an electric generator, a heat exchanger of heat of exhaust gas line of exhaust gases, hydroline, liquid pump with electric drive, check valve, tank with heater, recuperative heat exchanger for cooling the coolant with the electric fan, three-way valves with actuator, while the liquid pump with electric drive by means of hose that moves the coolant sequentially connected to the cooling system of the internal combustion engine, in which the integrated tank with heaters and heat exchanger-a heat exchanger of the exhaust gases, which is connected by means of hydroline with the first three-way valve with actuator, installed after the check valve on the hydroline, supplying the coolant from the internal combustion engine of the vehicle to the radiator hose heater of the vehicle and the recuperative heat exchanger cooler coolant with the electric fan, the second three-way valve with actuator positioned before the liquid pump with the actuator and connects the outlet and the inlet and the coolant hydroline with internal combustion engine vehicles, also on the highway exhaust gases exhaust gases of the engine NR the internal combustion supplied to the heat exchanger to heat their warmth.

In Fig.1 shows a diagram of a liquid heater of the internal combustion engine.

The liquid heater of the internal combustion engine includes an internal combustion engine 1, which is connected with the generator 17, the container heaters 2, the heat exchanger of heat of exhaust gas 3, the check valve 4, the three-way valves with actuators 5 and 8, the regenerative heat exchanger cooler coolant with the electric fan 6, a liquid pump with the actuator 7, the line of exhaust gases 9, hydroline 10, 11, 12, 13, 14, 15, 16.

The liquid heater of the internal combustion engine works as follows.

When the internal combustion engine 1 (Fig.1) the generator 17 generates electricity that is intended for consumers on-Board electrical system of the vehicle (primarily for charging its battery, the power fluid pump with the actuator 7, the heating of the coolant in the tank with heaters 2). Liquid pump with electric drive 7 delivers the coolant to the cooling system of the internal combustion engine 1, in which the integrated tank with electric heating elements 2. The flow of coolant passing through the cavity of the cooling system of the internal combustion engine 1, agrawals and enters the tank with electric heating elements 2. In the tank with electric heating elements 2 mounted tubular heaters, which can be connected to the mains, as all at once, or separately. The operation of the tank with heaters 2 controls automatic control system, which includes them during the regime of intense heating of the internal combustion engine of the vehicle (Fig. not shown) or during preheating of the internal combustion engine 1. In the tank with electric heating elements 2 of the coolant flow is additionally heated and sent to the heat exchanger-the heat exchanger exhaust gas 3. In turn on the highway exhaust gas 15 to the heat exchanger the heat exchanger exhaust gas 3 is supplied from the internal combustion engine 1 exhaust gas. Utilizarea heat exhaust gas stream of the coolant is heated to a final temperature in the circulation loop and goes for a three-way valve 5 with the servo. Three-way valve with actuator 5 is mounted on the hydroline 12 after the check valve 4, thus preventing the return of the coolant at the inlet of the circulation pump with the actuator 7. The work of the three-way valve with actuator 5 controls the automatic control system. In case of excess temperature coolant to enter the 90C automatic control system provides a control signal to the three-way valve with actuator 5 so the flow of coolant is directed through the hydroline 16 to the heat exchanger to the cooler coolant electroinsulation, where its heat is dissipated into the surrounding air. After the heat exchanger cooler coolant her thread, hydroline 16 is supplied to hydroline 13. In all other cases, the three-way valve with actuator 5 directs the flow of coolant through the hydroline 10 to the radiator to the heater of the vehicle (Fig. not shown), and then hydroline 11 removed from him in hydroline 13. If the ambient temperature is above 0C, three-way valve with actuator 8 covers the upper part of the hydroline 14. In this case, the flow of coolant is directed through the lower part of the hydroline 14 to the liquid pump with the actuator 7. Thus, there is no flow of coolant flow in the cooling system of the internal combustion engine of the vehicle on the hydroline 13. When the ambient temperature is below 0C, and also in cases when you need to forced heating of the internal combustion engine of a vehicle, the automatic control system overlaps with the help of the three-way valve with actuator 8 of the lower part of the hydroline 14. In this case, the flow of coolant through the hydroline 13 is supplied to the motor inside nego combustion vehicles. When the heating of the coolant in the internal combustion engine of the vehicle up to 40C three-way valve with actuator 8 covers the upper part of the hydroline 14, and the bottom opens. As a result, the flow of coolant starts flowing only to the liquid pump with the actuator 7, and the heating of the internal combustion engine of the vehicle stops. The heating of the motor vehicle resumed only when the temperature of a coolant in it to 35C by overlapping three-way valve with actuator 8 of the upper branches of hydroline 14 and opening her bottom.

During operation of the motor vehicle depending on the temperature of the coolant three-way valve with actuator 8 can provide the movement of the coolant through the liquid heater of the internal combustion engine at the top of the hydroline 14, and passing it hydroline 12, check valve 4, three-way valve with actuator 5 to the hydroline 10 and next to the radiator to the heater of the vehicle.

Declared a liquid heater of the internal combustion engine can be used as an auxiliary power unit on heavy duty vehicles, agricultural machines, road-building Masha is Oh, the locomotives for the production of heat and electricity. Its use will improve the efficiency of the system preheating vehicle through his warm-up coolant and engine oil to provide heat and electrical energy during long stops in the cold season, as well as expand service capabilities during operation in any climatic conditions.
