摘要： PROBLEM TO BE SOLVED: To enable an engine to make a high output without increasing a capacity of a low pressure stage turbocharger, in a supercharging device having a low pressure stage turbocharger and a high pressure stage turbocharger. SOLUTION: When an engine speed Ne and the torque Te of an internal combustion engine 10 exist in a high speed-high load area large in exhaust energy, a low pressure stage exhaust control valve 24 is controlled in a half-opening state, and a high pressure stage exhaust control valve 44 is controlled in a half-opening state, and an intake control valve 34 is controlled in a closed state. A part of exhaust gas from the internal combustion engine 10 bypasses a high pressure stage turbine 42, and flows through a low pressure stage turbine 22, and the remainder of the exhaust gas from the internal combustion engine 10 passes through the high pressure stage turbine 42, and flows by bypassing the low pressure stage turbine 22. Thus, intake air pressurized by a low pressure stage compressor 21 and bypassing a high pressure stage compressor 41, and intake air bypassing the low pressure stage compressor 21 and pressurized by the high pressure stage compressor 41 are introduced to the internal combustion engine 10.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine capable of preventing a reducing agent added in heavy EGR (exhaust gas recirculation) operation from entering a suction system through an EGR passage due to exhaust pulsation. SOLUTION: Two divided exhaust manifolds 5 and 6 are connected to an engine body 3. Superchargers 10A and 10B are connected to the downstream of the exhaust manifolds 5 and 6, respectively. A reducing agent adding nozzle 28 is mounted to an exhaust port corresponding to the first cylinder #1, and the reducing agent (fuel) is added into a branched tube 5a of the exhaust manifold 5. On the other hand, an EGR port 32, as a connection spot of an EGR tube 22, is placed at a branched tube 6c of the exhaust manifold 6. When the reducing agent is added from the reducing agent adding nozzle 28 in the heavy EGR operation, the reducing agent flows through the supercharger 10A into an exhaust tube 18 and never flows back to the other supercharger 10B; thus not flowing into the EGR port 32.
