Known technical solutions for using liquefied natural gas as fuel in motor vehicles with internal combustion engines (ice), which includes the engine and the heat-insulated container with cryogenic liquid fuel. However, the transition to natural gas in internal combustion engines leads to a fall in efficiency and deterioration starting properties engines (Kershenbaum C. J., Falk C. E. Horizons transport equipment. M.: Transport, 1988, page 109).

Known power unit with Stirling engine and low fuel, comprising a container of liquefied gas, the Stirling engine, the supply line of the gas in the combustion chamber, passing through the refrigerator motor and providing maximum decrease in low temperature cycle engine (RF application N 96115098, bull. N 29 from 20.10.98). However, this setting is not intended for the simultaneous production of mechanical energy and cold.

Known energoholding installation, which includes the inverter direct cycle, thermally insulated tank with low-fuel line fuel supply to the heater is Ling, having a cooling system with a pump associated with the gasifier (EN 96116770 A1, F 02 C 1/04, 20.11.1998). However, in this device, the heater of the Stirling engine is placed in the combustion chamber, which reduces the durability of this node when operating on hydrogen fuel.

The technical result, which can be obtained by carrying out the invention is to improve the efficiency of the Converter direct cycle energoholding installation and additional useful energy.

To achieve this technical result energoholding installation with low-temperature fuel, comprising a Converter direct cycle, thermally insulated tank with cryogenic fuel, such as liquefied natural gas), the supply line fuel shutoff and solenoid valves, throttle valve and the cooler (evaporator) with, as a Converter direct cycle, Stirling engine, the contour of the tank with liquefied gas, comprising an intake pipe in the area of the liquid fraction of the fuel regulating valve associated with the accelerator pedal of the engine, gasificatio and the exhaust pipe in the zone of the vessel with gaseous fraction of fuel, camera heater, expansion turbine with the consumer power on the same shaft and expansion tank, and the engine cooling system with coolant and the pump, and exhaust gases from the engine flow through the heater supply line of the fuel, and the engine cooling system through the gasifier loop container with liquefied gas.

The introduction of energoholding installation with low-temperature fuel circuit tank with liquefied gas of the Stirling engine, cooling system which is associated with the gasifier loop capacity, and the exhaust gases pass through the heater supply line of the fuel, which includes turbine with consumer power, you get a new feature consisting in the use of low-temperature fuel, first for engine cooling, while the minimum temperature of the cycle of the engine is reduced below the ambient temperature, and then cooling the refrigerating chamber, and after heat exchange with exhaust gases as the working fluid to the expansion turbine, with additional energy.

The drawing shows energoholding installation with low-temperature fuel.

Energy is 2, loop 3 of the container 2, the supply line fuel 4. The Stirling engine 1 includes refrigerator 5, the combustion chamber 6 and the cooling system 7 consisting of a cooler 8, associated with the environment, the pump 9.

Loop 3 of the container 2 includes an intake pipe 10 located in the area of the liquid fraction of the fuel tank 2, the control valve 11 associated with the accelerator pedal (not shown), the gasifier 12 and the outlet 13 located in the zone of the gaseous fraction of the vessel 2. The circuit 3 is connected with the cooling system 7 through the gasifier 12.

Line fuel 4 in engine 1 includes a control valve 14, the throttle valve 15, the refrigerating chamber 16, the heater 17, the expansion turbine 18 with the consumer power 19 on the same shaft, the surge tank 20. Highway exhaust gases 21 of the engine 1 passes through the heater 17.

Energoholding installation with low-temperature fuel works as follows.

Liquid cooling system 7 of the engine 1 is fed to the gasifier 12 circuit 3, which is adjustable through the accelerator pedal (not shown) of the control valve 11 is supplied liquefied gas from the zone of the liquid fraction of the vessel 2 Creese, expands under pressure enters the zone of the gaseous fraction of the vessel 2 through the exhaust pipe 13. From the tank 2 gas with high pressure and low temperature flows into the supply line fuel 4. Passing through the control valve 14, the gas is choked in ventile 15 and flows into the refrigerating chamber 16 where it cools the internal environment of the chamber 16 to the desired temperature, the heated pressure increase. From the cooling chamber 16, the gas is supplied to the heater 17, where by heat exchange with exhaust gases of the engine 1 is heated to a high temperature with simultaneous pressure increase. Gaseous fuel from the heater 17 is fed into the expansion turbine 18, which expands and performs useful work to be passed to the consumer power 19. After this gas through the expansion tank 20 flows into the combustion chamber 6 of the engine 1. The exhaust gases through line 21 are fed into the heater 17 and after cooling are released into the environment. The purpose of the cooling of the Stirling engine 1 is provided by the cooling system 7. In this system, heated from the working fluid of the engine 1, the coolant from the cooler 5 by a pump 9 is supplied to the cooler 8 where heat is mperature environment. The liquid is then fed into the gasifier 12, where it is cooled to a temperature below the ambient temperature due to heat exchange with liquefied gas and is fed again in the fridge 5. Due to the heat exchange of the coolant with a low temperature and the working fluid of the engine 1 is reduced lower temperature cycle of the Stirling engine 1, which leads to increased efficiency.
