ABSTRACT:
A supercharging pressure controlling device for an exhaust gas turbocharger having a turbine and a compressor comprises a velocity control device for exhaust gas flow and a bypass valve control device, the bypass valve control device provided into the bypass channel for the turbine to increase the opening when the downstream supercharging pressure of the compressor exceeds a first set value. The velocity control device controls the exhaust gas velocity by varying the degree of valve opening when the downstream supercharging pressure of the compressor exceeds a second set value, wherein the first set value of the supercharging pressure is higher than the second set value.
