SYSTEM AND METHOD (EMBODIMENTS) OF CONTROL OF TURBINE GENERATOR BY MEANS OF VALVE DISCONNECTION IN SEPARATE EXHAUST SYSTEM OF ENGINE Russian patent published in 2019 - IPC F01L1/00 F01N5/04 F01N13/10 F02D13/02 F02B37/00 

FIELD: machine building.

SUBSTANCE: invention can be used in the internal combustion engines. Method of engine operation includes the following stages. Exhaust gas supply from first outlet valve (E1) of cylinder (20) to gas turbine (92) along first exhaust header (59). Turbine drives generator (94). Exhaust gas supply from the second exhaust valve (E2) of the cylinder to catalytic neutraliser (72) bypassing the turbine along the second exhaust header (57). Selective disconnection of the first outlet valve in response to the fact that the turbine rpm exceeds the threshold value of the turbine rpm. Invention discloses engine operating method and engine system.

EFFECT: technical result consists in improvement of utilization of energy of exhaust gases and simplification of design of exhaust system.
