SUPERCHARGED INTERNAL COMBUSTION ENGINE Russian patent published in 2022 - IPC F02B37/10 F02B37/14 F02B39/10 F02D41/00 B60W20/00 

FIELD: engine building.

SUBSTANCE: invention can be used in internal combustion engines. Internal combustion engine (100) includes valve mechanism (102) of gas distribution, electric gas turbine supercharging (106) and control unit (114). Valve mechanism (102) of gas distribution is designed to close inlet valves (104) of internal combustion engine (100) for a time provided by Miller or Atkinson cycles. Electric gas turbine supercharging (106) is equipped with electric machine (112), which selectively operates as an engine or as a generator. Control unit (114) is intended for use of electric machine (112) of electric gas turbine supercharging (106) as an engine in the first range of load on internal combustion engine (100). Control unit (114) is intended for use of electric machine (112) of electric gas turbine supercharging (106) as generator in the second load range corresponding to higher loads on internal combustion engine (100) in comparison with the first load range. Valve closing time of timing mechanism (102) does not change. Internal combustion engine (100) additionally includes the second electric machine (122) made in the form of a power machine for conversion of electric energy received from electric gas turbine supercharging in the second power range. In the exhaust gas flow of the internal combustion engine (100) there is waste gate (136). Control unit (114) is additionally designed to open bypass flap (136) on one of the sections in the second load range, which corresponds to high loads within the second load range. Vehicle with engine is disclosed.

EFFECT: enabling implementation of Miller or Atkinson cycles without using complex controlled valve mechanisms of gas distribution.
