Abstract

The invention makes it possible to increase the efficiency of internal combustion engines operating in a closed cycle. The gas mixture preparation device 4 simultaneously feeds exhaust gases from a diesel engine and a highly concentrated alkali solution and oxygen gas from reactor 3. In device 4, the exhaust gases are cleared from products of incomplete combustion of fuel, carbon dioxide absorption, water vapor absorption by concentrated alkali, enrichment oxygen gases and heat removal by an integrated heat exchanger. Maintaining the temperature of the gas mixture within the specified limits is carried out by the regulator 11 of the temperature of the gas mixture, and maintaining the concentration of oxygen in the gas mixture within the specified limits is carried out by regulator 10 of the oxygen concentration. 1 il.

Description

FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular engine-building, in particular to internal combustion engines operating in a closed loop.

The purpose of the invention is to increase efficiency.

The drawing shows the scheme of the proposed engine.

The diesel engine 1 is equipped with a radiator 2 of the cooling system, a reactor 3 for producing alkali and oxygen, a device 4 for preparing a gas mixture with an integrated regenerative heat exchanger (not shown), a cooler 5 for a gas-liquid mixture, an ejector 6, a buffer capacity 7, a regulator 8 for product consumption reaction, the accumulator 9 reaction products, regulators 10 and 11, respectively, the oxygen concentration in the gas mixture and the temperature of the gas mixture and the collector

12 water supply. The diesel engine 1 is connected to the outlet gas port of the device 4 by an exhaust channel (not shown), and an inlet channel (not shown) with the outlet port of the buffer tank 7. The buffer tank 7 is connected via the ejector 6 to the gas outlet port of the device 4, the second liquid outlet through which the flow controller 8 is connected to the liquid inlet of the storage tank 9 of the reaction products, the gas outlet of which is connected to the suction inlet of the ejector 6, the reactor 3 is connected to the gas inlet through the cooler 5 the rest of the mixture with the gas-liquid inlet pipe of the device 4, which is connected to the outlet pipe of the built-in heat exchanger with the gas mixture temperature controller 11 and through the controller 10 to the reactor inlet pipe 3, and the inlet heat exchanger inlet pipe through the cooler 5 and the radiator 2 with the collector 12 water supply.

The engine works as follows.

The high-temperature exhaust gases from the diesel engine 1 are fed through the gas inlet to the device 4, which are simultaneously fed from the reactor 3 through the gas-liquid pipe previously cooled in the cooler 5. highly concentrated alkali solution and gaseous oxygen obtained from the solid oxygen-containing substance by the reaction

2NaG2 + H2O 2NaOH + 3/202 + Q. (1)

In the device 4 for the preparation of the gas mixture, the exhaust gases are purified from the products of incomplete combustion of fuel, the absorption of carbon dioxide by the reaction

C02 + 2NaOH Na2C03 + H20 + Q, (2)

absorption of water vapor by concentrated alkali, enrichment of gases with oxygen and heat removal by the built-in heat exchanger. Maintaining the temperature of the gas mixture within the predetermined limits is carried out by the regulator 11 by changing. The flow of water through the heat exchanger built into the device 4 and maintaining the oxygen concentration in the gas mixture within the specified limits by the regulator 10 by changing the flow rate of water supplied to the reactor 3. MagSO3 C residues of unreacted alkali NaOH are removed from the bottom of the device 4 through the flow regulator 8 to the accumulator 9, in which the ejector 6 maintains a low pressure, which boils the reaction products entering into it and separates the dissolved gas from its dissolved gas, the resulting gas mixture consisting of purified from carbon dioxide of exhaust gases, water vapor and oxygen, from device 4 are received successively through, ejector 6, in which water vapor and gases from accumulator 9 are sucked, buffer capacity 7. in which the pulsation of gases occurs and accumulation of part gas to ensure stable operation of the engine on variable conditions in the intake duct of the engine 1.
