FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines. Proposed method for ICE (1) consists in that supercharging air is forced, at increased power output, with pre-compression into ICE by two-step supercharge from low-pressure stage (ND) and high-pressure stage (HD). At low power output, supercharge air is forced with pre-compression into ICE (1) by compressor as the third supercharge pressure. Invention disclosed versions of supercharge assembly to this end.
EFFECT: high power output irrespective of geodesic altitude.
