ABSTRACT:
In a turbocharged engine, a pressure sensor is disposed downstream of the blower of the turbocharger and protective devices such as an alarm lamp for requiring the operator to lower the supercharging pressure and means for interrupting fuel feed to the engine are actuated under the control of a control circuit, when the supercharging pressure detected by the pressure sensor exceeds a preset maximum supercharging pressure. The control circuit does not permit the protective devices to operate unless the detected supercharging pressure continues higher than the preset maximum supercharging pressure for a predetermined time interval.
