Abstract
An exhaust bypass type turbo-charger includes a turbine driven by an exhaust gas from an internal combustion engine, a compressor driven by the turbine and supplying a compressed air into the engine, an exhaust bypass valve for controlling an amount of the exhaust gas bypassing the turbine, a drive mechanism for fluidly driving the exhaust bypass valve, and a transducer. The transducer communicated fluidly with both the drive mechanism and an outlet of the compressor, and amplifies the pressure variation of air discharged from the compressor so that the amplified pressure variation is applied in the drive mechanism. The drive mechanism, therefore, can start to open the exhaust bypass valve at a relatively smaller pressure, and fully open it at a relatively larger pressure.
