Using EI ZTS low molecular gas can improve the thermodynamic properties of the working fluid in a diesel engine (to reduce heat capacity), thereby improving fuel economy.

EI works as follows

Working mixture was transferred to an absorption in the diesel engine 1, is formed in the mixing chamber 7 and is composed of an oxidant (oxygen), low molecular weight gas and combustion products. Oxidizer enters the mixing chamber (IC) 12 from the tank 7 storing oxidant previously passed capacitors 14 and 27, a pressure reducing device 20 and the freezer 17. The low molecular weight gas in the IC is supplied from tank 7 via conduit 8, 9, and the exhaust gases (RG) coming 7 in the UK from the gas exhaust system. Diesel fuel is fed in from the tank 1 through line 2 3.

Exhaust gases produced during the combustion process in the cylinders of the diesel engine 1 comes into a cavity 6 preheater 4, where they are cooled in the heat exchange with the working mixture flowing to the suction of the engine 1 through the cavity 5 of the heater. The resulting mixture is increased to boost the temperature of the temperature. Then sent to the SH convection cooler 10, they contain water vapor is condensed and removed the pump 41 over the side, the separated oil and fuel enter the settling tank. As cooling medium used in cooler 10 Outside water from the engine cooling system. Then separation WG recirculation regulating valve 11 is performed in such a way that formed in the combustion gas part enters the cavity 19 of the freezer 17 and the remainder in IC 7. The freezer 17 is further cooled condensate and freeze SH residues. Refrigerant cooling gas is supplied to the freezer chamber 18 from the tank 12, after having passed the capacitors 14 and 27. In operation, the installation occurs plugging cavity 19 of the freezer 17 the ice formed from the condensate, so to function settings freezer 17 holds a two-piece. In the process of the formation of ice in the first section of the second is its defrost, and formed water is removed pump 41 overboard. 17 from the freezer gases enter the duct 42 where there is a mixture of CO ₂ gas formed in the jacket 35 of the ice maker 33, and additional cooling.

For preparing solid combustion products must have a maximum density of the liquid CO ₂ phase. The existence of the liquid phase is possible only at pressures above the critical 5.3 atm, so the compressor 23 the gas pressure increases to 6 ata. Then the gases are fed to a cooler 26, in which a cooling medium is used seawater from the cooling system of a diesel engine. From cooler 26 the gas mixture is sent to the condensers 27 and 14, which by heat exchange with oxygen is first cooled to a CO ₂ condensation temperature of -50 ^{o C,} the pressure of 6 ata Corresponding then condense carbon dioxide. The resulting two-phase medium is sent to a separator 30 where the carried phase separation, then liquid carbon dioxide is poured into the inner cavity 34, the icemaker 33, and the gas phase consisting of oxygen and low-molecular gas enters the mixing chamber 7 through the conduit 21 and further to the composition of the working fluid at absorption in one or diesel as a refrigerant is directed through conduit 22 to the cooling chamber 18 of the freezer 17.

Oxygen tank 12 is stored in liquid state in pressurized January 5 ata and with a temperature of 50 100 K. The cryogenic pump 13, it is fed under a pressure of 30 to 40 atmospheres oxygen in the cavity 15 of the second stage of the condenser 14. In the condenser 14 in heat exchange with the condensing liquid CO ₂ oxygen is vaporized and heated to a dew point of carbon dioxide to minus 50 ^o C. Then, the decompression device 20 expands the refrigerant, while the pressure is reduced to the boost pressure, and the temperature is reduced to 115 ^o C.

From device 20 downward pressure oxygen is supplied into the cavity 28 of the condenser 27, in which the cooling of the SH and the beginning of _the CO ₂ condensation. The refrigerant is then directed into the cavity 18 of the freezer 17, from which the IC enters the part 7 and the working medium is supplied to a diesel engine 1 absorption.

In the inner cavity 34 of the ice maker 33 during downward fluid pressure below the critical value, the liquid phase CO ₂ is separated into a solid (dry ice) and gaseous. The gaseous carbon dioxide through a gas jacket 35 flows into conduit 42.

After completing the crystallization process, the CO ₂ dry ice briquette enters the airlock chamber 36 via the inlet channel 37, then channel 37 is blocked and the chamber 36 is sealed, then through the channel 38 into the lock chamber 36 is supplied seawater. After pressure equalization in the outboard chamber 39 is opened outlet channel and the preform of dry ice under the action of gravity is removed overboard. Then, the channels 38 and 39 are closed and the airlock 36 through the channel 40 is drained pump 41.

Calculations for PA with underwater autonomy of 72 hours and PP containing DW 50 kW shows that by excluding from the EC refrigeration unit, durable storage tanks for liquid CO _2, but also the removal of the resulting combustion products overboard possible to improve the weight and size characteristics of the power plant about 40 while increasing efficiency of the plant from 22 to 37 due to the improvement in the workflow combustion engine operating on a mixture comprising a low molecular weight gas, reducing the power required to drive the compressor flue system and exceptions to the drive power loss of the refrigeration unit.
