FIELD: engines.
SUBSTANCE: present invention may be used in turbocharged internal combustion engines. Turbocharged internal combustion engine (1) has at least two turbo-compressors (8, 9), at least two cylinders (3) and the head (2) of cylinders which may be connected to the cylinder block from the side of the assembly end. Each cylinder (3) has at least two outlet openings (4A, 4b) for discharging the exhaust gases. At least one of the outlet as engaged opening (4a). Each outlet opening (4a, 4b) is connected with exhaust pipes (5a, 5b). Exhaust pipelines (5a) capacities of engaged outlet openings (4a) of at least two cylinders (3) are connected to each other forming the first outlet manifold (6a) to form the first common exhaust pipeline (7a), which is connected with turbine (8a) of the first turbo compressor (8) of exhaust gases. Exhaust pipelines (5b) of other outlet openings (4b) at least, two cylinders (3) are connected to each other to form the second exhaust manifold (6b) to make the second common exhaust pipeline (7b), which is connected with turbine (9A) of the second turbo compressor (9). First exhaust manifold (6A) and second exhaust manifold (6b) are permanently connected to each other upstream two turbines (8A, 9A) by means of at least one not closed connecting channel (10). Exhaust pipelines (5a, 5b) of at least two cylinders (3) are connected to form two common exhaust pipelines (7a, 7b) inside the head of cylinders (2). Common exhaust pipeline (7a, 7b) is located on the side of the other common exhaust pipeline (7a, 7b) opposite to the assembly end. Invention discloses an engine operation technique.
EFFECT: technical result is reducing the amount of pipelines between the outlet holes on cylinders and turbines and reducing weight and length of exhaust pipelines.
