FIELD: machine building.
SUBSTANCE: present invention may be used in turbocharged internal combustion engines. Engine system with turbocharger comprises first scroll (100), second scroll (102), adapter (200) and spiral valve (220). Second scroll (102) is separated in fluid medium from first scroll (100) by means of separating wall (101). Adapter (200) is connected to outlet of outlet header, inlet opening of first scroll (100) and inlet opening of second scroll (102). Scroll valve (220) is installed inside adapter (200) and can be rotated depending on the exhaust gas pressure. Scroll valve (220) comprises front part (222) and rear part (224). Front part (222) is perpendicular to rear part (224). Disclosed are an engine with a turbocharger and an engine with a turbocharger.
EFFECT: technical result consists in reduction of pressure losses in turbine and in reduction of engine pumping losses.
