FIELD: engines.
SUBSTANCE: invention can be used in supercharged internal combustion engines. Engine actuation method comprises first charge provision with air having barometric pressure or below it into engine cylinder (14) through first inlet channel (30) and provision of second air charge subjected to supercharging, into same cylinder (14) through second, separate, inlet channel (31). Second air charge is subjected to supercharging by means of inlet compressor (52), driven by exhaust turbine (54). Invention discloses version of engine actuation method and engine system.
EFFECT: technical result consists in reduction of compressor and turbine dimensions.
