FIELD: engines and pumps.
SUBSTANCE: invention can be used in supercharged internal combustion engines. Supercharged internal combustion engine includes at least two cylinders, at least one cylinder head and at least two series-connected turbines (1) and (2). Each cylinder has at least one outlet for discharging the exhaust gases from the cylinder. Each outlet adjoins an exhaust gas line. Exhaust gas lines at least two cylinders are integrated together to form common exhaust gas line (5) inside the cylinder head so as to form built-in exhaust gas manifold (4). Two different-size turbines (1) and (2) are located downstream exhaust gas manifold (4) in common exhaust gas line (5). Common exhaust gas line (5) in the area downstream exhaust gas manifold (4) enters housing (3a) of the manifold and passes through housing (3a) of the manifold to small turbine (1). Housing (1a) of the first turbine, in which small turbine (1) is located, is equipped with at least one coolant jacket (1c) to form a cooling liquid device. Engine control method is described.
EFFECT: technical result consists in ensuring closer location of turbines to the engine.
