SUPERCHARGER CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

WIPO Patent Application WO/2013/031920

A1

The present invention relates to a supercharger control device for an internal combustion engine. Said supercharger control device improves energy efficiency with a simple architecture. A compressor (15a) for a supercharger (15) is disposed in an intake passage (12) for an internal combustion engine (10), and a turbine (15b) is disposed in an exhaust passage (11). A bypass passage (1) is provided so as to connect the part (11a) of the exhaust passage (11) upstream of the turbine (15b) to the part (11b) of the exhaust passage (11) downstream of the turbine (15b), and a wastegate valve (2) that opens and closes the bypass passage (1) in accordance with the supercharging pressure of the compressor (15a) is disposed in the bypass passage (1). An accumulator (6) that stores exhaust pressure is connected to the bypass passage (1) downstream of the wastegate valve (2). The accumulator (6) is connected to the upstream side (11c) of the turbine (15b) by a backflow passage (8). A backflow valve (9) that opens and closes the backflow passage (8) in accordance with output demands is disposed in the backflow passage (8).
