Safety device for turbocharged engine
A safety device is described for a turbocharged engine which is provided with a turbocharger comprising a turbine disposed in the exhaust passage and a blower disposed in the intake passage and connected with the turbine by way of a rotary shaft and in which the throttle valve is disposed in the intake passage downstream of the blower. The safety device consists of an engine protective means for controlling the maximum supercharging pressure in the intake passage, at least one pressure sensor for detecting the supercharging pressure downstream of the blower, and a control circuit which actuates the engine protective means when the supercharging pressure detected by the pressure sensor continues to be higher than a preset supercharging pressure for a predetermined time interval. The control circuit includes means for generating the predetermined time interval, the means for generating the predetermined time interval shortening the time interval as the difference between the detected supercharging pressure and the preset supercharging pressure increases.
