11: i) shaving refers to the engine solution, namely, engine-motley, in particular, to the arrangement of exhaust systems for cjrpaPo-1N1Sh1X engine gases internal to the combustion of gas turbines {ummaa;

The purpose of the invention is to reduce it; loss of energy exhaust ga-yuv internal combustion engine.

FIG. 1 shows the system of the view, FIG. 2 is the same, top view, in FIG. 3 - pressure stabilizers.

 The exhaust system contains at least one pair of exhaust manifolds 1 and 2 with inlet 3 and outlet A sections, at least one pair of pressure stabilizers 5 and 6, and gas receiving tatrubok 7 of the turbocharger 8, Collectors 1 and 2 are equipped with at least one a pair of annular vortex chambers 9 and 10. The exhaust manifolds 1 and 2 are connected to the exhaust pipes of the 11 and 12 cylinders of the engine. Stabilizers 5 and 6 are provided with each conical tapering nozzle 13 and 14 and are installed in the outlet section 4 of the collectors 1 and 2, the gas inlet 7 of the turbocharger 8 is connected to the output section A of the collectors 1 and 2. Each of the annular chambers 9 and 10 is located between the outlet openings 15 and 16 conical tapering nozzles 13 and 14 stabilized 2132282

Ditch 5 and 6 and gas inlet 7 of the turbocharger 8. The ratio of the areas of the end openings of 1 5 spit 16 and 1 / or 18 is equal to 0.45-0.55.

The exhaust system works as follows.

The exhaust gases from the exhaust pipes 11 and 12 of the engine cylinders enter the inlet 3 and outlet 4 of the exhaust manifolds 1 and 2. In the latter, pressure pulses are generated. The exhaust gases then enter the conical tapering nozzles 13 and 14 of the pressure stabilizers 5 and 6. In tapering nozzles 13 and 14, the amplitude of the pressure oscillations of the exhaust gases decreases, and the flow rate increases. Gases with high speed enter the gas inlet 7 of the turbocharger 8, increasing its capacity. Part of the gas is reflected from the turbocharger 8 and in the form of a rarefaction wave is directed in the opposite direction. Due to the presence of annular vortex chambers 9 and 10, the reflected wave is throttled. Making the area ratio of the end openings 15 or 16 and 17 or 18 equal to 0.45-0.55 allows optimum conversion of pressure pulses.
