PROBLEM TO BE SOLVED: To suppress that air in a system is discharged to an atmosphere resulting from the operation of an air bypass valve for avoiding a surge, in a supercharge engine in which compressors are arranged in two upstream-side intake passages, respectively, and a throttle valve is arranged in a downstream-side intake passage which is composed of an aggregation of the two upstream-side intake passages.SOLUTION: An air bypass valve control device performs synchronous opening control for constantly simultaneously opening both a first air bypass valve arranged at a first compressor and a second air bypass valve arranged at a second compressor. |
