Zusammenfassung:	PURPOSE:To detect surge phenomenon of a supercharger automatically, by utilizing compressor inlet pressure signal of the supercharger. CONSTITUTION:A cylindrcial cover 8 is installed to a compressor inlet 7 of a compressor 5 of a supercharger 1, and a pressure sensor 9 is attached thereto. Output of the pressure sensor 9 is entered in a bridge 11 and conversion of pressure- electric signal is performed. Signal of the bridge 11 is entered in an AC amplifier 12, and output of the AC amplifier 12 is entered in comparators 13, 14. Reference level of the comparator 13 is set to a level to enable the detection of small pulsation, and referenc level of the comparator 14 is set to a level to enable the detection of large pulsation.
