The system is characterized in that an ejector 6 is installed between the exhaust pipe 2 of the internal combustion engine 3 and the inlet of the gas turbine 1 so that the inlet for the driving gas flow of the ejector 6 is connected to the exhaust pipe 2 of the internal combustion engine 3, the inlet for the driven gas flow of the ejector 6 is connected by a pipe 7 to the outlet of the gas turbine 1 (to which the pipe or system 4 for discharging of the exhaust gases is connected in parallel) and the outlet for the aggregate gas flow from the ejector 6 is connected to the inlet of the gas turbine 1.

[0017] In one variant embodiment of the system according to the invention, at least one of the inlets or outlets of the ejector 6 is adjustable by a regulating device 8 which is connected to a controller 9 which in turn is connected to at least one sensor 10 (as seen in FIG. 2) for any one of the operating parameters of the internal combustion engine 3 or of the consumer of the mechanical energy 5. In this variant embodiment of the system, depending on the application of the internal combustion engine and the need to regulate the ejector 6, additional regulating devices 8 can be installed at the other inlet of the ejector 6 and/or at the outlet for the aggregate gas flow of the ejector 6.

[0018] In a second variant embodiment of the system, the pipe 7 is connected to the outlet of the gas turbine 1 by a non-return valve 11 (shown in FIG. 2). It is of the type of the known non-return valves with movable valves, or of the so-called non-return valve of Nikola Tesla, without moving parts.

[0019] In a third variant embodiment of the system, the tube 7 encompasses the gas turbine 1 and the ejector 6.

[0020] In a fourth variant embodiment, the system is characterized in that a gas chamber 12 is installed between the pipe 7 and the inlet for the driven gas flow of the ejector 6 (as seen in FIG. 2).

[0021] In a fifth variant embodiment of the system shown in FIG. 2, it is characterized in that a device 13 for temperature and/or energy separation of the exhaust gases flow is installed between the outlet of the gas turbine 1 and the pipe or system 4 for discharging of the exhaust gases . This is one of the known devices of such actionfor example, the Ranque-Hilsch vortex tube. The high-temperature/high-energy outlet of the device 13 is connected to the pipe 7, and the low-temperature/low-energy outlet is connected to the pipe or system 4 for discharging of the exhaust gases.
