FIELD: engines and pumps.SUBSTANCE: invention relates to the field of motor industry, namely, to propulsion engineering. A turbocompressor of an internal combustion engine comprises a bearing unit, where a rotor shaft is installed, with turbine and compressor wheels, a body of a centripetal turbine fixed on the body of the bearing unit, and a body of a compressor stage also fixed on the body of the bearing unit. In the body of the compressor stage there is at least one hole arranged on the external surface of the nozzle in the place of transition from a curvilinear to a rectilinear section, at the same time the diameter of the hole does not exceed the thickness of the nozzle wall.EFFECT: invention is aimed at increased reliability of combination engines due to improved quality of air arriving to a cylinder.2 dwg |
