SYSTEM FOR ADDITION TO EXHAUST GAS INCLUDING EXHAUST GAS ADDITION DISTRIBUTION APPARATUS AND EXHAUST GAS ADDITION DOSAGE APPARATUS Russian patent published in 2021 - IPC F01N3/20 

FIELD: machines.

SUBSTANCE: present invention relates to a system of supply of a combustion engine (2) exhaust system for a turbo-compressor turbine (6) wherein the supply system includes a distribution apparatus (24) and a dosage apparatus (26). The distribution apparatus (24) includes a receiving surface (40, 46, 54) and at least one distribution surface(-s) (42, 48, 56). The receiving surface (40, 46, 54) is designed to receive addition to exhaust gas supplied to the distribution apparatus (24). The distribution surface (42, 48, 56) is in fluid communication with the receiving surface (40, 46, 54) and is designed for distributing addition to exhaust gas in the exhaust gas flow through the turbo-compressor turbine as a result of rotation of the distribution apparatus (24). The distribution apparatus (24) is firmly attached to the shaft (20) or a hub of the turbo-compressor turbine (6). The dosage apparatus (26) includes a inlet channel (28), a dosage valve (30) and a dosage valve (32) located downstream from the dosage valve (30) along the flow of the reducer. The distribution apparatus (26) is designed for supplying addition to exhaust gas to the receiving surface (40, 46, 54) of the distribution apparatus (24). The invention also relates to a distribution apparatus and a dosage apparatus for use in such supply system.

EFFECT: invention enables manufacture of a system of supply of a combustion engine exhaust system for a turbo-compressor turbine.
