Second turbine, the work of the second compressor is driven, is discharged into air afterwards；Air is entered by the first compressor and the second compressor respectively
Enter, the compressed air of the first blower outlet, burning is participated in by respectively enteing A, B row cylinder air inlet communicating pipe；Second calms the anger
The compressed air of machine outlet, the path between controlled triple valve second channel-first passage, is respectively enterd by air inlet communicating pipe
A, B row cylinder participates in burning, and now first and second turbocharger is devoted oneself to work, i.e., double turbine supercharging mode of operations in parallel.
