FIELD: engines.
SUBSTANCE: invention can be used in internal combustion engines with supercharging for exhaust gases recirculation control systems. Method is intended for actuation of engine (10) containing first supercharger (120) with first compressor (122) and second supercharger (130) with second compressor (132). Method consists in circulated gases flow difference (EGR) increasing between EGR flow into first compressor (122) and second compressor (132) in condensation state through bypass valve (214). EGR flow difference between EGR flow into first (122) and second (132) compressors in stalling state is reduced through bypass valve (214). Invention discloses engine bypass valve actuation method and engine system.
EFFECT: technical result consists in reduction of condensate accumulation probability and compressor damage in stalling state probability reduction.
